Small plastic injection mold processing customized process flow?

Small plastic injection mold processing customization process is a complex and fine process, involving a number of links and professional technology. This process is described in detail in several major stages.

Stage 1: Design and modeling

Before starting processing, we first need to design a three-dimensional model of the mold according to the product requirements. This stage requires the use of CAD (computer aided design) software, such as SolidWorks or UG, to carry out the structural design of the mold. The design should consider the shape, size, tolerance and other factors of the plastic parts, as well as the specifications of the injection molding machine and the requirements of the injection molding process. After the design is completed, it is also necessary to analyze the strength, stiffness and hot runner of the mold to ensure the rationality of the mold design.

Stage 2: Material selection and preparation

The material choice of the mold is very important, which directly affects the service life, accuracy and cost of the mold. Commonly used mold materials are steel, alloy steel, hard alloy and so on. When selecting materials, factors such as hardness, wear resistance, corrosion resistance and heat treatment performance need to be considered. After the material is ready, it also needs to be pre-treated, such as cutting and grinding, to achieve the size and accuracy suitable for processing.

3 stages: Machining

Machining is the core of mold manufacturing process. This stage includes milling, turning, grinding, EDM and other processes. Milling and turning are mainly used for rough machining of the mold, and grinding is used to improve the surface quality and accuracy of the mold. Edm is a special processing method, mainly used to process complex shapes and molds that are difficult to process with traditional methods.

4 stages: Heat treatment and surface treatment

Heat treatment is an important part of the mold manufacturing process, which can improve the hardness and wear resistance of the mold. Common heat treatment methods are quenching, tempering and so on. The surface treatment is mainly to increase the wear resistance, corrosion resistance and beauty of the mold, and the commonly used surface treatment methods are sandblasting, polishing, electroplating and so on.

Stage 5: Assembly and commissioning

When the various parts of the mold are processed, they need to be assembled. In the assembly process, it is necessary to ensure the accuracy and matching relationship of each part to ensure the overall performance of the mold. After the assembly is completed, it is also necessary to debug and test the mold, check the working performance of the mold and product quality, and correct the problem in time.

Sum up

Small plastic injection mold processing customization process is a complex and fine process, the need for design, materials, processing, heat treatment, surface treatment and assembly debugging and other links of close cooperation. Each link requires professional technology and strict quality control to ensure that the quality and performance of the final mold meet product requirements.
