China’s Pet Preform Mould Is Developing Rapidly

At present, the proportion of Pet Preform Mould in the mold industry is about 30%, and it is as high as 50 – 70% in the mold import and export.
In recent years, China’s plastic molds have developed rapidly. With the wider application range of plastic products, it provides a very broad market for plastic molds, resulting in a steady increase in the overall trend of the mold market. It is expected that 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. Plastic mold processing technology presents the following five major trends:
1. The parts of the mold forming parts are getting bigger and bigger, and the productivity requirements of the mold cavity are getting higher and higher, which leads to the larger and larger mold size. The large mold with large tonnage is as high as 100 tons, and one mold has hundreds of cavities. Thousands of cavities require large table tops for mold processing equipment, increase y-axis and z-axis travel, and have large bearing capacity, high rigidity and good consistency.
2. Mold processing high hardness steel mold materials, mold processing equipment requires thermal stability, high reliability.
3. For complex cavity and multi-functional composite molds, with the complexity of the shape of the workpiece, it is necessary to improve the mold design and manufacturing level, the function of forming a variety of grooves and materials in a group of molds or assembling components. Composite molds require a lot of programming, deep hole cutting ability and high stability, which makes processing difficult.
4. The fine processing of the mold makes the compounding and high efficiency of the processing equipment more attractive. High-speed milling has many advantages such as high-hardness material processing, stable processing, small cutting force, small workpiece temperature and deformation, etc., which makes mold companies pay more attention to high-speed machining.
5. High dynamic accuracy. China Pet Bottle machine tool manufacturers introduce static performance in the mold 3D surface processing, which does not reflect the actual processing. High-precision machining of the dimensions of the mold surface also requires high dynamic precision performance requirements, high-speed and high-precision can also be achieved in the machine’s high stiffness, thermal stability, high reliability and high quality control system.
