Today, with the rapid development of manufacturing industry, how to reduce the problems of long mold development cycle, high cost and high quality has become a new goal. The editor will explain how to control the cost and cycle from the aspects of product design, production process and mold manufacturing.



product design



1. Plate selection



On the premise of meeting the current mold quality requirements, enterprises should try to adopt more common and mature technologies in the market. Different materials will also produce different results. For the emergence of these results, we can only present perfect products and put them on the market through multiple adjustments.



2. Product structure



In the development of multiple molds, the universality of products should be considered. In addition, the product structure should be simplified to avoid the increase of mold process or the complexity of mold structure.



3. Application of Synchronous Engineering

Stamping Synchronous Engineering (SE) is that in the product design stage, stamping technologists intervene in the product process analysis in advance to eliminate errors and defects in the design stage and shorten the development cycle of dies. It can be seen from the figure that after using synchronous engineering, a process link is omitted, so that tooling manufacturing can start in the shortest time and provide sufficient time for manufacturing.

Structure design of mould



The mature die structure not only takes into account the product material properties, shrinkage, forming temperature, elastic tensile deformation coefficient, but also takes into account the cooling water path and the speed of opening and closing the die. Reasonable mold structure can effectively prolong the service life of the mold and ensure the smooth production of the mold. Improve efficiency and reduce costs.



Die processing technology



Sharp tools make good work. The process arrangement of plastic mold is particularly important. Reasonable process arrangement can speed up the production cycle, shorten the processing time and effectively save the cost. And more importantly, accurate and reasonable processing can ensure the stability of the mold in the production process and prolong the service life. Some processing errors will lead to die welding. No matter how good the welding is, it is a loss to the die; In addition, poor processing may also affect the action of the mold, reduce the service life of the mold, and cause the plastic mold to crack or even break in the production process.

Mold accessories

We all understand that the shortest piece of wood determines the capacity of the bucket, but we often don't notice it when doing it. The mold is the same. Although the standard parts of mold accessories do not directly participate in the molding, they control the operation of the whole mold. The standard parts with excellent quality should have the characteristics of wear resistance, hardness, high precision and not suitable for deformation.



Polished or textured



Mold polishing is the last link of mold manufacturing. Polishing is directly reflected on the plastic parts, so this is the most face-saving work. Polishing can also help and supplement the mold action, especially for demoulding. Often some mold production is not smooth because the polishing is not in place, the resistance is too large, demoulding is difficult, and even top white, top crack and so on.



Die assembly



Mold assembly is like assembling a machine. Every part and screw can't make mistakes, otherwise the consequences will be quite serious. At least, it will lead to product defects and affect production, or it will completely damage the mold and cause scrapping. Therefore, the assembly work must be very detailed. During the assembly process, pay special attention to the cleaning of the mold, especially the waterways and screw holes. Be sure to blow away the iron filings inside, otherwise the customer will be very angry.



Pure plastic mold steel is set according to the purpose, grade and order requirements before refining. Regardless of subsequent series processing and human factors, the theoretical service life of general plastic mold steel is 250000 ~ 800000 times, medium plastic mold steel is 800000 ~ 1 million times, and good brand plastic mold steel and patented steel will exceed 150 mold times or even higher.
