JINHONG Plastic Mold Factory Introduces Basic Concepts

  1. JINHONG Plastic Mold Factory introduces the general definition of plastic mold:

  In industrial production, various presses and special tools installed on the press are used to make metal or non-metallic materials into parts or products of the required shape through pressure. Such special tools are collectively called molds.

  2. Description of the injection molding process:

  Mold is a tool for producing plastic products. It is composed of several groups of parts, and there is a molding cavity in this combination. During injection molding, the mold is clamped on the injection molding machine, the molten plastic is injected into the molding cavity, and is cooled and shaped in the cavity, then the upper and lower molds are separated, the product is ejected from the cavity, and left the mold through the ejection system, and the mold is finally closed For the next injection, the entire injection molding process is carried out cyclically.

  Third, the general classification of molds: can be divided into plastic molds and non-plastic molds:

  (1) Non-plastic molds include: casting molds, forging molds, stamping molds, die-casting molds, etc.

  A. Casting mold, one tap, and pig iron platform;

  B. Forging die a car body;

  C. Stamping die a computer panel;

  D. A superalloy die-casting mold, cylinder block;

  (2) Plastic molds are divided into different production processes and products:

  A. Injection molding mold-TV shell, keyboard button (the most common application);

  B. Blow mold a beverage bottle;

  C. Compression molding mold, bakelite switch, scientific porcelain dishes

  D. Transfer molding mold-integrated circuit product;

  E. Extrusion mold-glue hose and a plastic bag;

  F. Thermoforming mold a transparent molded packaging shell;

  G. Rotational mold a soft rubber doll toy;

  4. Injection molding is the most commonly used method in plastic processing:

  This method is suitable for all thermoplastics and some thermosetting plastics. The number of plastic products produced is beyond the reach of other molding methods. As one of the main tools of injection molding processing, the injection mold is in terms of quality accuracy, manufacturing cycle, and injection molding process. The level of production efficiency and other aspects directly affect the quality, output, cost, and product update of the product, and it also determines the response-ability and speed of the enterprise in market competition.
