Designing and making a near-perfect mold is what every customer needs. During the design, there are many links and processes. In addition, during the use of the customer, the mold must be worn, and the service life of the mold will also wear out Continuously shortening, so merchants and customers need to improve the wear resistance of the mold, wear-resistant mold processing. The wear-resistant ceramic coating can meet the needs of merchants and customers. Let's take a look together.

Nano-ceramic coating of injection mold

A large amount of fiberglass material will be used in the injection molding process, or the use of other engineering plastics will bring more or less wear and corrosion to the mold, and the mold will also wear during the operation, which will vary to varying degrees The mold itself is damaged due to wear and tear. Nano-ceramic coating has high hardness and strong anti-corrosion performance. What is ultimately required is good wear resistance, which can effectively help the plastic mold to improve wear or corrosion. With the nano-ceramic coating, the use efficiency of the mold and the high toughness and wear resistance of the mold have been greatly improved. The advantage of the coating is that it can effectively improve the filling of the mold, can minimize the resistance to demolding, and can enhance the wear resistance of the mold.


 

In the modern injection molding process, glass fiber and engineering plastic are widely used, and the amount of use is increasing, and these materials themselves have extremely high hardness and corrosion resistance, so this puts forward the wear resistance and corrosion resistance of the mold. The new requirements require manufacturers to use better wear-resistant coatings for this situation. At present, the XR-I coating on the market is more widely used. Many mold processing manufacturers are using this coating to increase the wear resistance of the mold when performing mold wear-resistant processing. Mainly because of the high hardness, corrosion resistance and low friction coefficient of this coating, there are many colors of this coating, which can effectively improve the excellent performance of the injection mold. Generally, this coating is applied to injection molds and accessories or injection molding machine accessories.

What are the precautions for coating

1. Coatable materials

This coating can be applied not only on the surface of injection molds, but also on various mold steels.

2. Coated parts

This kind of coating is generally applied to the part where the mold is clamped, and it is almost impossible to achieve all coating. If there are special parts that cannot be coated, the merchant must inform in advance and clearly mark it on the mold and clearly mark it. The part that must be coated, the part that can not be coated, and the part that can be coated or not, so that the coating staff can apply the correct coating without causing trouble to the subsequent work.

3. Requirements for the surface of the coated workpiece

When coating the mold, the surface of the mold must not have other surface modification treatments. For example, surface modification treatments such as electroplating or oxidation blackening are not allowed. There are rust corrosion phenomena, and there can be no corrosion, or glue, etc., the smoother the surface of the mold, the better.

In short, the wear-resistant processing of the mold is very important, which is related to the service life of the mold. The mold processing manufacturers generally have this link to improve the wear resistance of the mold, but some businesses often reduce the cost without the customer ’s knowledge. Next, this link will be omitted quietly, so it is best for customers to do some understanding of mold related knowledge in advance, and choose a regular mold processing manufacturer, such as Xubang Mold Processing Co., Ltd. is a good choice.
