What factors affect mold performance

The Plastic injection mould building is very complicated. So many details need to work together. From design, machining, assembling, test and fix then finally go into the service. A lot of factors will affect the quality and performance of mold. We need to truly understand it to make the mold building get better.The steel type and quality is the most important thing for mold. It is the beginning and base for everything. So choose the right steel material is very important. There are many types for mold steel. Such as the of hot rolled steel and more. And maybe you need to focus on the points below to choose the right one.We all need good mold craftmanship to make it great. Great craftmanship can cut down the cost and working time efficaciously. If there are mistakes, it will cause the mold to become soldering. By the way, worse processing will influence the function of mold, decrease the life of mold, even it will get hurt and breakage in the processing of injection molding.

The polishing is the final part of mold production. Polishing also helps and complement the mold action, especially for mold release. Lots of the production of some molds are not smooth because the lighting is not in place, the resistance is too large, the demolding is difficult, and even the top is white and the top is cracked.The mold is just like assembling a machine. Every part and every screw must not go wrong, otherwise the consequences will be quite serious. May cause product defects, affect production, and even completely damage the mold, resulting in scrap. So the assembly work must be very detailed. During the assembly process, pay special attention to the cleaning of the mold, especially the water channels and screw holes. Be sure to blow off the iron filings inside.Anyone with years of mold experience knows how important cooling is to mold.

Due to the increase in prices and human wages, when producing products in large quantities, the profit brought by reducing the injection cycle by one second is unimaginable. However, when the production cycle is accelerated, the temperature of the mold will rise. If it is not effectively controlled, it will cause the mold to be too hot to form, and even cause the mold to deform and fail. Therefore, good cooling system design is particularly important, including the density, diameter, and interconnection of water channels.Mold maintenance is mainly maintenance and maintenance during production. Molds are like cars. If it is not used for a long time without maintenance, it may be scrapped and die. Therefore, after each use of the mold, comprehensive maintenance is required, especially the rust prevention of the molding part, and the rust prevention of the main moving parts.

Because the mold needs to receive water during the production process, the mold may be filled with water during the installation or disassembly process, so it is necessary to ensure that the mold is dry before applying a layer of oil to protect it.If the steel function is enough, then it is the best. Pay a lot of money to get much high steel performance is not necessary.Surface treatment also is very important. Nitrogen treatment can make the steel surface hardness get higher and make its surface life get longer. And electroplating can change the performance of mold steel. Some plastic need high luminance and corrosion-resistant, then we can use electroplating to raise and change the performance of steel.Good structure design not just consider the product material property: shrinkage ratio, the temperature of forming and more. But also need to think of the water part of the cooling. Great structure design can enhance the mold work time and maintain it can successfully produce products. That is huge for raising efficiency and cut down the cost.The demand for material for injection molding is that different plastic needs to pair up with different steel materials. And it also has the demand for corrosion resistance and polishing.
