When many users are designing new products or developing products, they usually focus on product development and development at the initial stage, or price, rather than communication and exchange with injection mold manufacturers. In fact, it is necessary to communicate with injection mold manufacturers in advance after determining the preliminary design scheme of products. Today, I will give you a specific introduction of injection molding What should be paid attention to when opening die for auto parts.

1. The choice of steel material is very important, which is related to the service life of accommodation mould. Since there are many kinds of dies, as many as ten kinds, different types of dies can be selected for forming according to the requirements of materials, mechanical strength, chemical and physical properties, surface finish, dimensional accuracy, etc. for the dies with high accuracy requirements, high-precision processing equipment is also needed, and in terms of forming process and materials, the The requirements are relatively strict, some need to use mold software to design and analyze.

2. Injection mold manufacturers should have complete equipment, including EDM, CNC, WEDM, etc., some need high-precision CMM, grinder or computer design software, some need special requirements for the design of plastic products, and the structure is also complex, which requires injection mold manufacturers to use advanced technology such as hot runner, oil cylinder, etc 。

3. For some large stamping dies, such as the covering die of automobile, it is necessary to consider whether the machine tool has a blank holder mechanism, as well as edge lubricant and multi position progressive, etc. in addition, it is also necessary to consider the feeding device, punch and die protection device, etc.

When opening the injection mold, we must pay attention to the above contents. These contents are not mastered and possessed by every injection mold manufacturer. Therefore, when choosing the injection mold manufacturer, we must understand its processing ability, as well as its professionalism in hardware equipment, technical force and processing experience.
