What items should be managed in injection mold processing ？

Introduction

I believe that injection mold practitioners are no strangers to the projects that need injection pressure, to be managed during injection mold processing. Practitioners in the non-injection mold industry also need to deal with injection molds at work, especially in product development and product customization. Almost every product They are all inseparable from injection molds, which have been widely used in product manufacturing in various fields. So how can non-injection mold industry practitioners and injection mold users effectively manage injection molds?

II. Before injection mold processing

Before making injection molds, you need to find an injection molding factory with project management capabilities, entrust management or collaborative management. Before processing injection molds:

A. Process conditions

B. Molding materials

C. Mold life

D. Molding cycle

These four aspects can meet the production efficiency, cost control, and quality assurance of injection molding mass production after the injection mold cooling process and processing is completed.

III. Injection mold processing

When processing plastic injection for molds, you should know:

A. Injection mold processing technology

B. Processing time of each processing technology of injection mold

C, mold trial schedule

D. Criteria for mold evaluation at each stage

In these four aspects, try to avoid rushing to rush to launch the product on the market. If you understand the injection mold processing technology and processing time, then you will properly handle the coordination of the injection molding process, processing time and the product sales plan.

IV. After the injection mold processing is completed

After the injection and molding machine and processing is completed, you should know:

A. Whether the mold structure meets the design requirements

B. Does the product size meet the product design requirements

C. Does the product appearance meet quality requirements

D. Whether the product function violates laws and regulations

E. Whether the product materials meet the customer’s usage environment

These five aspects determine the speed of product sales. It requires full cooperation with the injection mold factory to adjust the mold to the best condition and enter mass production. The injection mold factory is professional, and the entrusting merchant should also understand the production sequence of the injection molded molds and provide technical cooperation and help for the product.

V. Injection mold mass production initial stage

In the early stages of mass production of injection molds plastic parts, various management and control items are not yet mature, and management items need to be clearly defined to prevent the injection mold factory from not managing them because there are no clear requirements from customers.

A. Full size report

B. Important dimension schedule management items

C. Mass production material manufacturer model

D. Appearance standard

E. Packaging and transportation requirements

F. Material test report

Projects with high pressure and no problems will remain as they are and will be inspected from time to time. Risky projects or problems that have been discovered and projects that are likely to cause problems based on experience will be managed as future schedule management projects. Projects that are prone to human changes will be monitored as key points, and only good quality can be maintained.

VI. Mass production management

A. Mold maintenance time

B. Repair and replacement list of wearing parts

C. Paid service items

D. Free services

Injection mold processing is a very systematic and huge industrial project. Injection mold factories generally calculate the injection mold processing costs step by step based on the customer’s own injection molding machines and processing requirements. You must understand that you get what you pay for, and the more you ask for, the more you get. One cost, one less requires more risk.

VII.Product design changes, mold repairs

A. Does the mold need to be welded when the product changes position

B. Is there any welding in the mold modification

C. Whether the important dimensions of the product are inserts

Conclusion

It is important not to change the product within a few days after the injection mold is processed. In more than 10 years of working in the injection mold industry, we have never seen a case where the injection mold made while changing the product design can be successfully mass-produced. Basically, the mold must be remade to ensure smooth production. mass production. Try to use insert structures for important dimensions of the product. When the dimensions are difficult to control, the inserts can be easily replaced, and the cost of size repair is relatively low. Welding of injection molds must be avoided, as the remaining weld scars will not be strong, and it is easy to weld the molten plastic mold over a large area. Deformation; good quality injection molds depend on solving the fundamental problems of the product in the product design stage. In the mold processing stage, the injection mold factory carefully carves out each process and conducts inspections to ensure the accuracy and life of the injection mold.
