  • Introduction to the cleaning method of plastic extrusion molding machine

    In plastic extrusion molding equipment, the plastic extruder is usually called the main machine, and the subsequent equipment that is matched with the plastic extrusion molding machine is called the auxiliary machine. After more than 100 years of development, plastic extruders have derived from the original single-screw, multiple-screw, multi-screw, and even non-screw models.

  • Control scheme of flow mark in polishing process

    So far, the most widely used system for chemical polishing of aluminum and its alloys is a mixed solution of sulfuric acid-phosphoric acid-nitric acid, copper and additives (hereinafter referred to as the triacid system). This system is widely used in domestic and foreign production lines under different commercial names for its advantages of easy maintenance, wide control range of triacid ratio, polishing temperature, water content, moderate polishing time, and high product measurement.

  • Characteristics of insert injection molding technology

    Insert molding (molding) refers to a molding method in which a pre-prepared insert of dissimilar materials is put into a mold and then resin is injected, and the molten material is joined and solidified with the insert to make an integrated product. Out-sert molding refers to a method of embedding injection molded parts on a part of a metal plate surface.

  • Common surface treatment methods for aluminum profiles

    Surface treatment is a process of artificially forming a surface layer on the surface of the base material that is different from the mechanical, physical and chemical properties of the base. The purpose of surface treatment is to meet the product's corrosion resistance, wear resistance, decoration or other special functional requirements. Common surface treatment methods for aluminum profiles:
