Plastic molds are tools in the plastics processing industry that are used in conjunction with plastic molding machines to give plastic products a complete configuration and precise dimensions. The utility model mainly comprises a concave die with a variable cavity composed of a female die combination base plate, a concave die component and a concave die combination card plate, and comprises a punch die combined substrate, a punch die assembly, a punch die combined card plate and a cavity cutting assembly. A punch with a variable core that consists of a combination of sideboards.
Polyester Resin is odor-free, non-toxic, high transparency, high strength and air-tightness, light weight and easy transportability, uniform size, stable viscosity, excellent processing ability and high product yield. In particular, the products fully conform to international standards for food-grade usages due to their low heavy metal, acetaldehyde and ash contents. These products are ideal 'green' materials for beverage bottle and food packaging.
There are different type for different products,water bottle grade,oil bottle grade,CSD grade,hot filling grade and sheet grade etc.

At present, the proportion of plastic molds in the entire mold industry is about 30%, and the proportion in the import and export of molds is as high as 50 to 70%. In recent years, China's plastic mold has developed rapidly. The application of plastic products has become increasingly widespread, providing a very broad market for plastic molds.
In addition, under the impetus of high-tech driven and pillar industry application needs, China's plastic molds have formed a huge industrial chain, from upstream raw and auxiliary materials industry and processing and testing equipment to downstream machinery, automobiles, motorcycles, and household appliances. Several major application industries such as electronic communications, construction and building materials, etc., plastic mold development is alive.
At the same time, the demand for plastics in the construction, home appliances, and automotive industries is large. It is estimated that only the automotive and motorcycle industries require more than 100 billion yuan worth of plastic molds each year, and color TV plastic molds also have a market of about 2.8 billion yuan each year.
It can be seen that the overall trend of the mold market is stable and upward. In the future mold market, the development speed of plastic molds will be higher than other molds, and the proportion in the mold industry will gradually increase.
