On the Design Concept of Export Injection Mold

1. Concept of export mold

According to the different design concepts and styles of molds, at present, the export molds can be simply divided into three categories, namely, the three standard systems. Japan and South Korea in Asia, and even Taiwan in China, the mold styles are very similar. The mold standards adopt Japanese standards and the representative is Misumi standards. The measurement unit adopts metric system, mainly soft mold, relatively short cycle of mold making, rapid product renewal. In addition to a few large companies, the popularity of hot runner is relatively low, and the cost performance of mold is relatively high.

2. Quality concept of export mold            

The most important factors that determine the reliability of the mold, in addition to the design and maintenance of the mold, also depend on the steel and heat treatment methods of the mold and the processing technology of the mold. A set of high-quality molds should fully understand and meet the needs of customers and be in line with customer philosophy, tailor-made solutions for different products of different customers. The criteria for judging the qualified export molds are whether they conform to the mold pattern sample book and whether the customers are satisfied.            

Different cultural concepts determine different mold structure forms. The concept of export molds is that the designed molds should conform to the design concepts of customers. Customer satisfaction is the only criterion to judge that the mold is qualified. We want to produce high-quality molds that customers are satisfied with and want. The quality concept, including the appearance of the mold, makes the guests think that the mold is tailored for them, and is elaborate. For example, polishing of the rear mold, the concept that the front and rear molds are equally important, and the aesthetic appearance of the mold should be paid attention to. Conditional large-scale export mold factories need to classify and manage customers. Different customer requirements are different, and different mold manufacturing process standards are formulated by different customers to meet their needs. The production of real materials, substitution of materials, etc. should communicate with the customers in advance and obtain consent. Select the appropriate die standard parts to meet customer needs. Acceptance period is the embodiment of credibility.            

Some people say that the criterion to judge the qualified mold is whether to produce qualified products, product size and position tolerances and appearance are in line with the drawings, at the same time, the mold can be operated for a long life, easy to maintain, long-term use of fault-free, if such conditions meet the good mold. This concept is suitable for domestic customers with extensive management, and obviously wrong for customers such as Europe, America and Japan. For example, a foreign customer originally had a product, long-term production has been for decades, due to cost considerations, the production line was transferred to China, the original injection cycle was 25 seconds, a new set of molds was opened in China, the performance of the product fully met the requirements, but the injection cycle required 30 seconds, the actual capacity was reduced by 20%, can you say that such a mold is qualified?     

3. Green manufacturing concept of export mold            

Green design makes use of all kinds of information related to products in the product life cycle and various advanced theories such as concurrent design to make the designed products have advanced technology, good environmental coordination and reasonable economy. Whether the product can meet the requirements of green standard depends on whether green design is adopted in the design. Green design involves many disciplines such as manufacturing, materials, management, sociology, environment, etc., and has strong interdisciplinary characteristics .The existing design methods are difficult to meet the requirements of green products, so green design is an integrated design, which is the integration of design methods and design processes. Green design integrates object-oriented technology, concurrent engineering, life cycle design and other system design methods, and integrates factors such as product quality, function, life and environment.            

The cost analysis of green products is different from traditional cost analysis. In the stage of product design, the performance of product recovery and reuse must be considered, so the cost analysis must consider the replacement of pollutants, product disassembly, reuse costs and corresponding environmental costs.   

4. Concluding remarks            

The design of export molds must conform to the design concept of customers. The customers in different regions of the world have different ideas about injection molds, which is determined by different cultural concepts. Export mold design needs to be familiar with the customer's mold standards and injection machine specifications, strictly in accordance with the customer's mold pattern book (MOULD SPECIFICATION) design. Pay attention to size detection, process according to drawing of die parts strictly, and eliminate traditional backward processes such as manual matching. We should constantly learn advanced European technologies and management concepts, and strive to improve the core advantages and competitiveness of enterprises themselves.
