What are the main problems in the injection mold industry?

1. Difficult to resolve supply-demand contradictions in the short term

At present, the import and export volume of molds in China is increasing year by year, and the market demand is strong. However, the production volume of most enterprises is difficult to keep up with the rapid development pace, and the situation of oversupply will continue for a period of time. According to relevant data, the satisfaction rate of the domestic injection mold market is less than 74%, and the satisfaction rate of large precision molds is relatively low.

2. Unbalanced industrial development

Although the products of individual enterprises have reached or approached the international advanced level, overall, the molds produced by domestic enterprises still lag far behind foreign enterprises in terms of precision, production cycle, and service life, and the overall level of industrial development is relatively low. 3. The overall technical level is outdated

In recent years, after technological transformation, the production technology of some enterprises has reached a high level, but compared with most enterprises, the overall technological level is still relatively backward. More importantly, enterprises have poor organizational and coordination abilities, making it difficult to integrate or mobilize social resources.

4. Insufficient innovation capability

Most enterprises have a low proportion of technical personnel, low innovation ability, low investment in scientific research, and outdated management systems. Therefore, greater emphasis must be placed on innovation and development.

In order to improve the current situation of the mold industry, mold companies need to start from the above four aspects, accurately grasp the personalized needs of customers in the first time, in order to develop steadily and rapidly. The following brief series introduces a common issue that customers face when choosing raw materials for manufacturing plastic products.

In daily life, there are many types of plastics, each with different names, and even the same material has different grades. The most important thing is that different types of plastics have different shrinkage rates. The so-called plastic shrinkage rate is the percentage difference between the size of the plastic at the molding temperature and the size taken out of the mold and cooled to room temperature. The main factors affecting the shrinkage rate of plastics are the type of plastic, the molding conditions during injection molding, the complexity of mold structure, the shape of plastic parts, and the presence of inserts.
