The improvement of the overall level of the mold industry is closely related to the development of related industries

China's mold industry will further adjust the structure, expand the market, practice internal skills, and improve the level, so that China's mold industry as a whole will reach a new level, and this is not just a "family matter" of the mold industry. The development of the mold industry and other industries can be described as interdependent, so the improvement of the overall level of the mold industry is closely related to the development of related industries.

The improvement of the overall level of the mold industry is closely related to the development of related industries

At present, China's mold products are mainly medium and low-end products, with low technical content. Most of the high-end and high-end molds rely on imports. One of the reasons is the lack of core technology in related industries. For example, in the field of IC packaging molds, due to the overall level of the domestic IC industry and the reasons for foreign technology blockade, it is difficult for the IC packaging mold industry to develop from a high starting point. Therefore, while the IT industry and the automotive industry drive the growth of demand for mold products, it is indispensable to enhance China's overall strength in the IT industry and the automotive industry.

In order to ensure the quality and reliability of the terminal block and prevent the occurrence of fatal defects, it is recommended to discuss and formulate corresponding technical requirements for selection according to the technical conditions of the product, and carry out the following targeted reliability inspections to prevent failures. At present, there is no such item in the product acceptance test of ordinary terminal manufacturers, and users generally need to stop the continuity test after installation. Therefore, it is suggested that consumer manufacturers should increase the products of some key models. Some terminals are used in dynamic vibration environments. The actual test proves that only checking whether the static contact resistance is qualified can not guarantee the reliable contact in the dynamic environment. Because the connectors with qualified contact resistance often still show the phenomenon of instantaneous power failure when suspending vibration, shock and other simulated environmental experiments, so for some terminals requiring high reliability, the dynamic vibration test is used to test their contact reliability. The single-hole separation force refers to the separation force of the contacts in the mated state from static to moving, which is used to indicate that the pin and the socket are in contact.

For this reason, it should not be used for the multi-point simultaneous measurement of the heavy-pulling force test machine to prevent the signal from being cut off due to the relaxation of individual jacks. The quality of raw materials has a great influence on the performance of the body. Therefore, the choice of raw material manufacturers is particularly important, and the quality of materials cannot be lost by blindly reducing costs. Should choose the reputable big factory material. And for each batch of incoming materials, important information such as material certification is required. Retrospective data used. At present, some manufacturers have technical regulations to assemble the waste products and then test the electrical performance. As a result, because the insulation body itself has different insulation resistance, the whole batch of waste products has to be scrapped.

In addition, the precision of mold design and development and mold technology in my country still needs to be improved. Most mold companies are still struggling in the mold industry. Repeated construction and vicious competition are common, which seriously restricts the development of mold companies. At the same time, it also restricts the development of the overall domestic terminal industry.
