High precision plastic molds have relatively high requirements for design, and the complexity of mold design is higher than that of general molds. Therefore, before confirming the commencement, all processes must be determined to avoid problems in the processing process. So what problems should we pay attention to in the design of high-precision plastic mold? Mastars（metal prototype maker,rapid cnc services） will show you. Choosing a high-tech, high-precision, high-service and high reputation mold factory is your wisest choice.


1. The precision injection mold design engineer analyzed the feasibility of the plastic product drawings provided by the customer, determined the mold structure, and strictly stipulated the product design process, which is the most important step. Pay attention to complete it carefully, which will also save a lot of time for the next step.


2. Prepare all kinds of materials required for precision injection mold design according to the analysis of product deployment diagram of precision injection mold design. Preparing materials according to the product deployment drawing can improve efficiency and accuracy, reduce errors and facilitate the rapid completion of design work.

3. Determine the opening direction and parting line position of high-precision plastic mold; At the beginning of the design, it is necessary to determine the mold opening direction and parting line of each plastic product to ensure Z greatly reduce the core slider mechanism and the influence of parting line on the appearance. After determining the opening direction of high-precision plastic mold, try to make the structural design of reinforcement, opening and protrusion of the product consistent with the opening direction, avoid core pulling, reduce joints and prolong the forming time.


4. After determining the opening direction of the high-precision plastic mold, the appropriate parting line can be selected to avoid the reverse buckle in the opening direction and improve the appearance and performance of the mold.

5. Properly adjusting the draft angle of high-precision plastic mold can avoid the damage of white edge, deformation and fracture on the top of the product. In the design of products with deep cavity structure, the inclination of the outer surface should be greater than that of the inner surface as far as possible, so as to ensure that the core of the plastic injection mold will not move, so as to obtain a uniform product wall thickness, and ensure the material strength and product opening time.

6. Each kind of different plastics has a certain wall thickness range, usually 0.54mm. When the wall thickness exceeds 4mm, it will lead to problems such as long cooling time and shrinkage of plastic products. We should consider changing the product structure. Uneven wall thickness will lead to surface shrinkage. And air holes and melting wires. In addition, the rational use of reinforcement can increase the stiffness of products and reduce deformation.

The above are the problems that should be paid attention to in the design and manufacturing of high-precision plastic molds. The design and processing of high-precision mold is a project with very high technical content, so we must find a professional mold design and development company.
