In recent years, China’s injection molds have developed rapidly in terms of quality and quantity. However, compared with foreign advanced technologies, the technical standards of most Chinese enterprises still need to be improved. At present, compared with foreign advanced technology, China’s injection mold industry mainly has the following problems.
The contradiction between supply and demand is difficult to solve in the short term. The domestic market satisfaction rate of domestic injection molds has been less than 74%, and the satisfaction rate of large-scale, precise and long-life molds is even lower. At present, the transfer of molds from industrialized developed countries to China is accelerating, and there are more and more international purchases. The market demand is strong, production development is still difficult to keep up for a while, and the situation of short supply will continue for some time.
Unbalanced industrial development Although the products of individual companies have reached or approached the international advanced level, in general, the accuracy, production cycle, service life and other indicators of molds still have a large gap compared with foreign countries, and the overall level of industrial development is low .
Generally speaking, injection molds are divided into thermosetting plastic molds and thermoplastic plastic molds according to the molding characteristics; according to the molding process, they are divided into transfer molds, blow molds, casting molds, thermoforming molds, and hot press molds (compression molds). ), injection molds, etc. The hot press molds can be divided into three types: overflow, semi-overflow, and non-overflow. The injection molds can be divided into cold runner molds and hot runner molds based on the gating system. ; According to the way of loading and unloading, it can be divided into two types: mobile type and fixed type.
