Description

Technical Field

[0001] The present application relates to the field of plastic manufacturing, and in particular to a three-in-one plastic extrusion mechanism with a precise temperature control system. Background Art

[0002] Plastic refers to a plastic (flexible) material formed by processing with a high molecular weight synthetic resin as the main component, or a rigid material formed by curing and cross-linking, with appropriate additives such as plasticizers, stabilizers, antioxidants, flame retardants, colorants, etc. Plastics are widely used in life and have brought great convenience to people's lives.

[0003] Generally, plastic products are made from one type of plastic particles as raw materials. With the development of plastic manufacturing technology, three types of plastic particles are hot-melted and mixed and then cooled to form mixed plastics. The performance of this plastic is better than that of the plastic made from the original single plastic particles. Since the melting temperatures of different types of plastic particles are different, a thermoplastic machine is needed to control the heating and plasticization of the three plastics at the same time to improve the yield rate of the plastic embryo board.
