The construction of Plastic Pail Mould is very complicated. So many details need to work together. From design, processing, assembly, testing to repair, and finally put into use. Many factors will affect the quality and performance of the mold. We need to really understand it to make mold making better.

Steel type and quality

The type and quality of steel are the most important to the mold. This is the beginning and foundation of everything. Therefore, it is very important to choose the right steel. There are many types of die steel. Cold rolled steel such as D3, A2, O2, D2 tool steel; H11, 1.2344, H13 hot rolled steel and other tool steels. Maybe you need to focus on the following points to choose the right point of view.

The demand for injection molding materials is that different plastics need to be paired with different steels. It also has corrosion resistance and polishing requirements.

If the steel is functional enough, it is the best. High steel properties can be obtained without spending a lot of money.

Surface treatment is also very important. Nitrogen treatment can make the surface hardness of steel higher and extend its surface life. Electroplating can change the properties of die steel. Some plastics require high brightness and corrosion resistance, and then we can use electroplating to improve and change the performance of steel.

Structural design

A good structure design must not only consider the material properties of the product: shrinkage, molding temperature and so on. And also need to consider the cooling part of the water. Excellent structural design can extend the working time of the mold and maintain its ability to successfully produce products. This is huge for improving efficiency and reducing costs.

Mold technology

We all need good mould craftsmanship to make it outstanding. Exquisite craftsmanship can effectively reduce costs and working hours. If there is an error, it will lead to mold welding. By the way, poor processing will affect the function of the mold, reduce the life of the mold, and even get hurt and cracked during the injection molding process.

polishing

Polishing is the last part of mold production. Polishing also helps and complements the role of the mold, especially for demolding. A lot of the production of some mould is not smooth, because the lighting is not in place, the resistance is too large, it is difficult to demold, and even the top is white and the top is cracked.

Mold assembly

The mold is like an assembly machine. Every part and every screw must not go wrong, otherwise the consequences will be very serious. It may cause product defects, affect production, or even completely damage the mold, resulting in scrap. Therefore, the assembly work must be very detailed. During the assembly process, special attention should be paid to the cleaning of the mold, especially the cleaning of the water channels and screw holes. Make sure to blow away the iron filings inside.

Mold cooling

Anyone with many years of mold experience knows the importance of cooling to mould. Due to the increase in prices and labor wages, when mass production of products, 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 cannot be controlled effectively, it will cause the mold to overheat and fail to form, and even cause the mold to deform and damage. Therefore, good cooling system design is especially important, including density, diameter, and interconnection of water channels.

Mold maintenance

Mold maintenance is mainly maintenance and maintenance during the production process. The mold is like a car. 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 molded parts and the rust prevention of the main moving parts. Since the mold needs to be filled with water during the production process, the mold may be filled with water during installation or disassembly. Therefore, it is necessary to ensure that the plastic pail mold is dry before applying a layer of oil to protect it.

We need to concentrate on these details and proceed in the right way to ensure that high-quality mould are produced to create a good product line.
