The mold manufacturing process is a complicated process. From the steps of design, processing, assembly, debugging, etc., it can be finally put into use. In the whole life cycle, the factors affecting the quality of mold manufacturing mainly include the following aspects:

1. Mold steel: Steel is the decisive factor of mold quality, and choosing the right steel is the most important. Injection molding materials require different steels to be used for different plastics, such as high polishing requirements, corrosion resistance requirements, etc.

2. Mold design, structural design: The mature mold structure not only considers the product material properties - shrinkage rate, molding temperature, elastic tensile deformation coefficient, etc., but also considers the cooling waterway, the speed of opening and closing the mold. Reasonable mold structure can effectively extend the life of the mold and ensure the smooth production of the mold. Improve efficiency and reduce costs.

3. Mold manufacturing and processing: The arrangement of the mold process is particularly important. Reasonable process arrangement can speed up the production cycle, shorten the processing time and save costs. And more importantly, accurate and reasonable processing can ensure the stability and longevity of the mold during the production process. Some machining errors will lead to mold welding, no matter how good the welding is, it is a loss to the mold; in addition, poor processing may affect the mold movement, reduce the mold life, and cause the mold to crack during the production process. Even broken.

4. Polishing/skinning: The polishing of the mold is the last step in the manufacture of the mold. Polishing is directly reflected on the plastic parts, so this is the most face-to-face job. Polishing also helps and complements the mold movement, especially for demolding. Often some mold production is not smooth because the lighting is not in place, the resistance is too large, the demoulding is difficult, and even the white, the top crack and so on.

5. Mold assembly: Mold assembly is like assembling a machine. Every component and every screw can't go wrong. Otherwise, the consequences will be quite serious. Lightness will lead to product defects, affecting production, and completely damage the mold and cause scrapping. Therefore, the assembly work must be very detailed. In the assembly process, especially pay attention to the cleaning of the mold, especially the water circuit and screw holes. Be sure to blow off the iron filings inside.

6. Cooling Waterway: Anyone with experience in mold knows how important cooling is to a mold. Due to the increase in prices and labor wages, it is unthinkable to reduce the profit from the one-second injection cycle when mass-producing products. However, when the production cycle is accelerated, the temperature of the mold will rise. If it is not effectively controlled, the mold will be too hot to be formed, and even the mold deformation will be scrapped. Therefore, excellent waterway design is particularly important, including the arrangement density of waterways, diameters, links between each other, and so on.

7. 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 cause the mold to be scrapped. Therefore, every time the mold is used, it must be fully maintained, especially the rust prevention of the molded part and the rust prevention of the main moving parts. Because the mold has to be watered during the production process, water may be supplied to the mold during the installation or disassembly process, so it is necessary to ensure that the mold is dry and then brush a layer of oil protection.
