Vietnamese Chinese injection molding factories, while ensuring the quality and precision of plastic products, strive to reduce production costs and improve efficiency. In this process, injection molds are crucial, serving as indispensable tools in the production process. Injection molds directly affect product quality and production efficiency, so it is essential to follow certain standards during mold manufacturing to ensure precision and reliability.
1. Material Selection
Material selection is critical in the production of injection molds. Mold materials must have sufficient hardness and wear resistance to ensure long-term durability. Common mold materials include high-quality tool steel, which also requires good machinability for processes such as cutting and polishing. Additionally, for specialized molds, like those used for transparent products, the transparency and high-temperature resistance of the material are key considerations.
2. Design Requirements
The design of the injection mold is the core aspect of the manufacturing process. A well-designed mold ensures excellent molding performance and stable production efficiency. During the design process, the mold structure should be chosen based on the shape and size of the product, such as single-cavity, multi-cavity, or insert molds. The structure should also be simplified as much as possible to reduce manufacturing costs and minimize the risk of malfunctions during production. Moreover, proper design of cooling and ventilation systems is essential for improving molding quality and shortening the production cycle.
3. Processing Techniques
The production of injection molds involves a series of processing techniques, including CNC machining, EDM (Electrical Discharge Machining), and polishing. During processing, it is essential to strictly follow design specifications to ensure mold precision and surface quality. CNC machining uses high-precision machines to process parts, ensuring the accuracy of the mold’s geometric dimensions. For molds with complex shapes, EDM is an indispensable fine-processing method. Additionally, surface treatments like polishing can enhance the mold’s surface smoothness and wear resistance. To ensure the processing techniques meet production requirements, it is recommended to partner with Kaidi Molds to meet high production standards.
