Surface finishing is a term used to describe the different types of manufacturing that work to improve the overall beauty and appearance, strength, and a host of other properties that make a finished product. One of these manufacturing processes is prototype manufacturing. They add, alter, remove, and reshape the material of a given product, and they are often achieved through the application of mechanics, chemicals, and electrics.

In all, sanding and polishing are part of the most popular ways to achieve a clean surface finish. Do you want to find out more about surface finishing, and all there is to it? Then keep scrolling:

Processes of Surface Finishing

While there are lots of processes used for surface finishing, here are the most common ones in the industry:

1. Sanding

This is easily considered the most popular process of surface finishing. It’s the process of getting rid of the surface material using a disk or an abrasive sheet. It’s recommended that you use the fovitic sanding method. That’s because it enables you to get past some general problems associated with sanding.

2. Polishing

Similar to sanding, polishing uses a finer means of abrasion to finish a surface. However, if you’re using robots to polish, you may encounter different factors that can affect its quality. These factors include; wear rate, connection to robot, the strategy used, etc.

3. Sand Blasting

Sandblasting is achieved by driving the abrasive beads onto the desired surface. This helps to rapidly remove the material.

4. Electro polishing

This is a surface polishing process that involves the use of chemicals instead of mechanical procedures to polish. Electro Polishing is often used to remove the surface of stainless steel.

5. Passivation

The common agents used during passivation are nitric or citric acid. They help to remove free iron on the surface of the steel to improve its resistance to rust.

6. Electroplating

This process uses electricity to coat one metal alongside a bonded thin layer of a different metal.

Must Surface Finishing Always Involve Manual Operation?

A lot of processes used for surface finishing require that you use manual operation. But for some such as polishing, sanding, or buffing, you can perform them using a robot.

How Does Surface Finishing Work?

When performing a surface finish, the end goal is usually to improve a product’s appearance, chemical or mechanical properties. Depending on the process you’re using, you can achieve surface finishing in different ways. Nonetheless, they can be divided into four categories. You can either:

• Add Materials -this is a process of including extra material on the product’s surface. It can be done through galvanizing, powder coating, or plasma spraying.
• Alter Materials- Pickling, carburization, or flame polishing are the different ways that you can alter the chemical or material properties of a product.
• Remove Materials- This is done through the use of chemicals or abrasive media.
• Reshape Materials – Here, chemical pressure is added to define the surface of the material.

Final Thoughts

Before performing surface finish on your product, you should understand what the process entails. This guide shows you exactly how surface finishing works.

A flexo printing plate is a light-sensitive plate (photopolymer) used to transfer ink to a substrate during printing. There are different ways of processing these plates: digital, traditional, and thermal flexo plate processing. Note, the plates’ specifications vary depending on the process used, but one thing that should remain constant is the methods to maintain them. In this extract, we discuss the tips for maintaining a flexo printing plate.

Tips for Maintaining a Flexo Printing Plate

1.Relief Depth

A plate has two sides, the bottom side, the floor of the plate, and the upper side, also known as the printing surface. This is the side that the prints appear. The difference between the two sides is what is known as the relief depth. The depth varies with each plate depending on the thickness. Each plate thickness has a recommended depth that should get considered for you to produce a high-quality plate.

2. Quality of Image

The original image plays a significant part in determining the quality of the flexo plate. Whether the processing machine uses a digital or traditional plate, the final product will match the original one. If the quality is poor, the end product will also be of low quality and vice versa. When using film to develop traditional plates, the film density must be kept over 4.0. The digital plates, the imager should get checked to ensure the focus and settings are okay. Lastly, the test should be done periodically and, most importantly, done by an expert.

3. Drying Process

Using flexographic plates before they are completely dry shortens their life span and leads to poor registration. The plate is an essential part of the printing process as it transfers ink to the printing material. A wet plate appears swollen due to solvent retention. Certain factors may cause a plate not to dry completely, such as poor air circulation in the dryer or removing the plate from the dryer earlier than intended.

4. Conditions of Exposure

The printing room should be kept clean, free from dust and dirt. These slowly damage the plates, reducing their life. Also, the plate has two UV bulbs that need to be checked regularly and also replaced. Weak bulbs may extend the exposure time but lead to widened plate shoulder angles, damaging the flexo plates.

5. Saturation of the Polymer

The plate making solvents use water or hydrocarbon solvent to wash away excess polymer found in the plates non-printing areas. During this process, the polymer solids are contaminated, and how saturated they determine the plate’s quality. The concentration of the solids should be kept below 6%. The machines should also be cleaned often to remove all-polymer particles that may build up over time.

6.Plate Handling

The plates are delicate and fragile; hence should be handled with care. A plate should not be folded, placed on sharp objects, exposed to harsh chemicals or direct sunlight.

Conclusion

The factors discussed above are essential and should be considered when maintaining the plate’s quality. Remember, when plates are well maintained, your printing quality will always be top class, and lastly, the very plates will last long.

There are a lot of different finishing services. A lot of them reshape and remove the surface layer of products. These different finishing techniques could be applied to different materials, tighter tolerances, increased durability, improved functionality, and better appearance.

So if you are ready to learn about the various types of finishing services in greater detail, click that link and let’s get started!

Common Types of Finishing Service

Below is a list of the main kinds of finishing services.

1. Electro Polish Finishing Service

This type of Finishing Service uses electric current to get rid of materials from machine surfaces and their components. These processes improve the finish of surfaces by levelling out valleys and micro peaks on the layer of the metal surface, created during the process of machining.

Further, Electro Polish is the opposite of electroplating, which uses current to put on more materials on the surface of machine components.

2. Grinding Finishing Service

This refers to the process that uses grinding wheels that are abrasive to get rid of materials from the top of precision components. This helps to improve the surface’s finish and create accurate dimensions, and they also lead to a wide variety of applications. These all depend on the geometry of turned components.

There is centered grinding, which might be used to finish the process. Grinding is usually done using Outside Diameter, Inside Diameter, and several other components like flats, slots, and holes.

Grinding is divided into two different parts:

● Honing

This refers to a grinding subset. It is used from the Inside Diameter of the precision component, which is machined. Even though honing is a grinding process, it tends to appear more like a polishing process. Honing processes make use of rotating stones which is also known as hone. These have clear abrasives that get rid of delicate layers on the surface of the material.

● Lapping

Lapping is the second subset of grinding. It is used on the Outer Diameter (OD) to serve as a turned precision component, improving the finishing service and creating tight dimensional control. This process has abrasive materials which serve as paste forms that are applied on lap plates. These components are passed against plates to get rid of the polish available on the top layer.

3. Laser Engraving Finishing Service

This refers to the process that uses lasers to make images like numbers or letters on the logo appear on the top of a specific Machined component. The laser beams make the metal vaporize. The entire process is used when the shape or font required cannot get created through the milling or turning method. Because the font cannot reach using normal methods like turning or milling, laser engraving finishing service type is used instead.

Final Thoughts

In all, finishing services have a lot of types, and rules that aid qualified partners to finish their finishing service tasks quickly and with haste. Finishing services can be applied to different sectors such as the medical and engineering industry. They aid in the creation of finished components that meet several essential requirements. These finishing service types end up being essential to provide needed finished products.

In factories, factory tools and machinery were manually moved by humans since most of the lathes and milling machines were manual. However, with the advent of technology, most machines in the factory have become computerized. As a result, CNC milling machines have replaced the manually operated ones. With Computer Numerically Controlled (CNC) machining, the movement of factory machinery and tools is controlled by computer software. There are several advantages that CNC milling has over manual milling. These benefits include:

Consistent Quality

Computers are always accurate as compared to humans. The accuracy of some computers is close to 99%. Consequently, using CNC machines will give you the consistent quality of your end product. You should note that cnc milling machines are also more precise. You can repeat the desired process over and over. Even better, if you want to make improvements or alterations, you only have to do it once by updating the software.

Increased Efficiency and Production

Since computers are used to control the milling machines through computer software, machine operation is automatic. The automation of the process increases the speed of manufacturing. Besides that, it also increases the quality of the whole manufacturing process. Machines also do not get tired or require breaks. This makes CNC milling machines more efficient than manual milling machines.

Safety

One of the most significant advantages that CNC machines have over manual machines is safety. Manual machines require human input. Milling machines have rotating parts. Therefore, people operating the machines are usually at risk of getting injured by the machines. Using CNC machines is very safe as they can be set up behind closed safety doors.

Cost-Effective

Traditional milling machines need one human operator per machine. For CNC machines, one operator can operate several machines simultaneously. Therefore, the cost of operation of CNC machines is lower than that of manually operated milling machines.

How CNC Milling Machines Work

The most common feature of CNC milling machines is that the part to be machined is usually clamped, directly or through a fixture or a vice, on top of the machining table. The cutting tool and the spindle is either horizontally vertically positioned. This arrangement makes it easy to achieve the desired shape of the material being machined. The cutting tools rotate at very high speeds along to or more axes.

Parts of a CNC Milling Machine

Some of the central parts of a CNC milling machine include frame, spindle, axes, columns, and control panel. The frame holds the entire machine and gives it stability. It usually consists of several detachable columns and a base. The spindle is the “heart” of the machine since it houses the rotating parts. The CNC control panel is the “brain” of the machine tool. It consists of electronics used to control the machines’ cutting actions to achieve different shapes and designs.

In most CNC machines, the control panel is usually within easy reach for ease of operation. Some machines also come with manual functionality to support the electronic functions in case of a malfunction. This means you can always fulfill orders from your customers.

The continuous spread of COVID-19 has an impact on the rapid manufacturing industry. Supply chains, coupled with markets, have been affected. As the number of affected patients who need treatment continues to increase, healthcare providers are experiencing shortages in essential equipment, with ventilators topping the list.

The World Health Organization reiterates that 75% of COVID-19 patients recover without the need for hospital treatment. But two in seven people become ill. In such cases, the coronavirus damages the lungs. It also causes the oxygen levels of the body to drop. This makes it hard to breathe.

For this to be alleviated, a ventilator is used. It takes over the patient’s breathing system when the lungs fail. This gives a patient time to fight off the coronavirus and recover.

After realizing that there is a shortage, governmental calls to the rapid manufacturing sector have been made to help produce and mobilize ventilators from manufacturers to service providers.

Additive manufacturing initiatives have also been spearheaded to help track the development of ventilators to meet demand. Simultaneously, networking sites such as LinkedIn have become the hallmark for sourcing solutions coupled with signal boosting devices of various local calls for assistance.

To help reduce the rising number of infections, Governments have reached out to rapid manufacturing industries to help in the production of ventilators and other PPE kits to support the healthcare industry.

Among them is the European Union, which just approached the Machine Tool Industry to produce equipment lacking in hospitals. Following this call to action, AM companies are using their skills to produce ventilators.

The government of the United Kingdom has also called on businesses, including those with RP skills, to send blueprints to ventilator manufacturers. Aerospace and automotive companies heed to this call by forming teams to manufacture ventilators.

According to healthcare researchers, one of the projects includes building a variety of oxygen systems for military aerospace applications.

The USA is reportedly going to connect the AM industry’s capabilities with the healthcare providers’ particular needs using an online repository.

When the month began, AM German AM companies spearheaded the acceleration of rapid prototyping services in transport to help reach out to patients who needed instant medical attention.

In just about three days of issuing the call, the healthcare departments reported having received support in materials and capacity from more than 200 RM companies.

The coronavirus spread has affected the world’s economy in many ways, including sending most furlough workers. That is why government officials are contacting RP companies to supply ventilators and other PPE kits.

Medical devices used to diagnose and treat coronavirus patients include diagnostic tests and ventilators. There is a vitro diagnostic test conducted on various samples of mucus swabs harvested from the nose for testing.

A blood sample can also be taken from the patient’s finger prick. It is important to note that testing is crucial to diagnosing coronavirus and getting accurate numbers.

Final Thoughts

As more hospitals in the world continue to face shortages in ventilators, engineers, and physicians across the world have partnered to find out how to make ventilators at lower cost.

Prototype machining services are crucial in the manufacturing process. You can’t build a house without blueprints. Prototyping in some industries requires a fast turnaround for testing and adjustments. Take into consideration the medical sector. Hospitals require implants and other parts. These parts are mainly made of Titanium due to their biocompatibility. The structural composition of Titanium makes it strong and hard to corrode with bodily fluids. To make parts or prototypes using Titanium, you will require a method with equipment capable of slicing through hard metal. Since these parts are used to replace human organs, they are required high precision and quality surface finishing. The slightest mistake can cause discomfort or even harm to the people using them. Customization is another necessity in the medical sector since one part cannot fit everyone.

In the past, creating a part or prototype with all these necessities intact was unthinkable. The main disadvantage of making these parts manually is human error. However, the invention of CNC machining changed everything. Believe it or not, CNC machining started about a half-century ago. Of course, the equipment used was not as complex as the ones we have, but the concept behind them was the same. Prototype machining allows you to created parts fast at a lower cost with high precision.

Just like other prototyping methods, there are specific parameters you should consider when choosing prototype machining services.

Volume

CNC prototype machining is suitable for low or medium production. Today, you can find CNC machines ranging from simple tabletops to complex multi-axis units. This gives you the freedom to develop multiple prototypes at the same time. CNC machines are controlled by numerical programs meaning that if one unit is making several prototypes, uniformity is maintained.

Material

You can’t blindly choose prototyping services without putting into consideration the type of materials you are using. There are certain materials that a CNC machine cannot work with. In this case, it would be best if you went for alternatives like 3D printing.

Precision and Consistency

Some prototypes require high precision and quality surface finishing, as seen in the medical and automotive industries. CNC prototype machining is the best option for high precision part production.

Geometry

The geometry of your prototype plays a crucial role in determining the choice of production. CNC machining supports geometric complexity since on prototype can pass through different stages in the machining process and is guided by a computer program, meaning that errors rarely occur. A CNC shop has different tooling, each specialized to perform a task efficiently. If a drill will not give you what you need, there is always the mill or the cutter.

Benefits of CNC prototype Machining

1. Unlike 3D printing, metals used in CNC machines are not heated, and as a result, they maintain structural integrity. Structural integrity is key in industries like automotive and aerospace since parts are placed under extreme conditions.
2. CNC prototype machining allows you to choose from a wide range of materials since the tools used can work with very hard metals.
3. If you have the materials readily available, you can produce parts in a couple of hours, making your production cycle shorter—rapid tooling further aids in reducing the time required to develop parts.

You can find in Germany most of the big companies in manufacturing. It is a place with lots of opportunities for companies all over the world. Most of its residents live in urban areas. Because of this, Germany is considered one of the biggest and in-demand markets in the world of products and services.

Products Germany Imports

Germany has an open economy and a wide variety of goods that it imports. Businesses in the country add value to parts and raw products. Here is the Germany import list from China:

• Agricultural products
• Chemicals
• Data processing equipment
• Electric equipment
• Foodstuffs
• Machinery
• Metals
• Oil and gas
• Pharmaceuticals
• Vehicles

Besides China, other top countries that export to Germany include the Netherlands, France, Italy, and the US.

Europe comprises 70% of its total imports, Asia at 20%, and the remaining 10% is from other continents. It only shows that if you have a product with quality or cost advantage over European products, you can do business in Germany.

Germany Exports and Imports

In 2015, the worth of Germany’s exports was around 1,410 billion dollars as compared to 1,130 billion dollars of total imports. It’s because of this, the trade surplus in Germany is 280 billion dollars during that year. Germany is the top exporter of vehicles, household equipment, machinery, and chemicals thanks to the efficient and highly-skilled labor force.

Trade Relations of Germany with China

Germany has been exporting to China for many years. In 2000, the total export was over € 9 billion and had grown to € 67 billion in 2013. German exports to China are mostly in the engineering sector. Cars components and vehicles comprise one-fourth of Germany’s export to China. Next is the machinery, followed by the optical industry, chemical goods manufacturers, and the aviation industry.

Germany’s import from China has increased from € 18 billion in 2000 to around € 73 billion in 2013. China is the second most source of import of Germany next to the Netherlands. Most of the products being imported from China are electrical and electronics (27%) and the machinery products (21%).

Furniture, toys, and garments are among the essential import goods before, but now it is decreasing rapidly as China’s export process is becoming more advanced.

China’s Investments in Germany

When it comes to investment volume, Germany tops the destination for Chinese industrial investment. The skilled labor force and infrastructure is the main reason for this. Germany is the best option for outbound investment when it comes to China’s policy.

Chinese investment in Germany is distributed over various industries. The main recipients of Chinese include the automotive, chemical, machinery, telecommunications, and energy and other sectors.

The trading between the two countries continues and is building a better relationship when it comes to importing and exporting their products. However, both countries need to comply with the changing rules and regulations to have worry-free and stress-free trading. They need to find a reliable air or sea freight services to help them process the necessary documents to complete the shipment.
