As a mature technology of thin-wall mold manufacturers, Leiao molding has manufactured 1-12 cavity thin-wall mold for customers, and Leiao molding production of plastic box products, appearance luster, no burr, is recognized by many customers. So here’s a look at the thin-wall die manufacturing process.
1.Process analysis of plastic products.
Before the mold design, the designer should fully analyze and study whether the plastic products conform to the principle of injection molding and processing, which needs to be carefully negotiated with the designer of the products, and has reached a consensus. It includes the necessary discussion on the geometry, dimensional accuracy and appearance requirements of the product, and tries to avoid the unnecessary complexity in the mold manufacturing.
2. Mold structure design.
A set of high-quality mold, not only need to have a good processing equipment and skilled mold manufacturing workers, another very important factor is to have a good mold design, especially for the complex mold, the mold design accounts for more than 80% of the quality of the mold. A good mold design is to make the processing cost of the customer is low, the processing difficulty is small and the processing time is short.
3. Determine the mold material and select standard parts.
In the selection of mold materials, in addition to consider the accuracy and quality of the product, but also combined with the processing and heat treatment of the actual ability of the mold factory to give the correct choice. In addition, in order to shorten the manufacturing cycle, make use of the existing standard parts as much as possible.
4. Parts machining and mold assembly.
The accuracy of the mold in addition to give the best structure and reasonable tolerance in the design, parts processing and mold assembly is crucial. Therefore, the choice of machining accuracy and machining method dominates in mold manufacturing.
5. Test Mode.
A set of molds from the design to the assembly, only 70% to 80% of the entire manufacturing process. For the error caused by the inconsistency between the predetermined contraction and the actual contraction, the smooth mold release, the cooling effect, especially the size, position and shape of the gate on the accuracy and appearance of the product, must be tested through the mold test. Therefore, the mold test is an indispensable step to check whether the mold is qualified and choose the best molding process.
