  • .Winding molding process is to wrap the continuous fiber (or cloth band, pre -immersed yarn) soaked in the resin glue in accordance with a certain regularly, and then solidify and remove the products.
  • Layer pressure molding refers to the combination of multi -layer or different materials under heating and pressure. Commonly used for plastic processing and rubber processing.
  •  Watering molding is a method of plastic processing. Early casting was to see the polymer into the mold into the mold under normal pressure. In the 1960s, the nylon single casting seeing the development of polyamide with the development of molding technology, the traditional casting concepts have changed. The polymer solution, decentralized polyvinyl chloride paste paste and melt can also be used for casting molding.
  •  Drop plasticity is the characteristic of the use of thermoplastic polymer material, that is, under certain conditions, it has adhesive, and the characteristics of solid state can be restored at room temperature. It is shaped into a design form according to its sticky state, and then solidified at room temperature.
  • The compression molding method is mainly used for the production of thermosetry plastic products. After the molding is heated, it melts, press the mold, and then solidified through heating.
