Yesterday, one of our customers sent us three new plastic basket samples which need to make injection molds.
After getting the samples, SWY MOULD begins making designs soon.
1. Steel type and quality
The steel type and quality is the most important thing for plastic fruit basket mold. It is the beginning and base for everything. So choose the right steel material is very important. There are many types of mold steel. Such as the P20, 1.2344, H13, S136 tool steel of hot rolled steel, and more. And maybe you need to focus on the points below to choose the right one.
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. 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 is corrosion-resistant, then we can use electroplating to raise and change the performance of steel.
2. Structure Design
Good structure design does 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 Toilet Water Tank Injection Mould work time and maintain it can successfully produce products. That is huge for raising efficiency and cut down the cost.
3. Mold Assembly
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.
4. Mold Cooling
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.
5. Mold Maintenance
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.
The plastic mold 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.
