Plastic injection mold Introduction


  Plastic molds are further divided according to the production process and production products:

A. Injection molding die - TV casing, keyboard button (the most common application)

B. Blowing mold - beverage bottle

C. Compression molding die - Bakelite switch, scientific porcelain dishes

D. Transfer molding die - integrated circuit products Extrusion molding die - glue pipe, plastic bag

F. Thermoforming mold - transparent molded packaging shell

G. Rotation molding die - soft plastic doll toy


     Injection molding is the most commonly used method in plastic processing. The method is applicable to all thermoplastics and some thermosetting plastics. The amount of plastic products produced is far beyond the reach of other molding methods. As one of the main tools for injection molding processing, the injection mold is in the quality precision, manufacturing cycle and injection molding process. The level of production efficiency and other aspects directly affects the quality, output, cost and product renewal of the product, and also determines the ability and speed of the company's response in the market competition.


   The injection mold is composed of several steel plates combined with various parts, which are basically divided into:

A forming device (core, cavity)

B positioning device (guide pin, guide bush)

C fixing device (mold plate, Mold A & B plate frame)

D Cooling system (water hole)

E temperature control system (heating pipe, heating wire)

F Injection system ( nozzle hole, runner groove, runner hole)

G Ejecting system (ejector pin, K.O)


   Molds can be divided into three categories depending on the type of gating system:

(1) direct sprue gating mold: The runner and gate are on the parting line, and the product is demolded together when the mold is opened. The design is the simplest, easy to process, and the cost is low. Therefore, many people use the large nozzle system.

(2) Pin point small gating mold: The runner and gate are not on the parting line, generally directly on the product, so it is necessary to design a set of nozzle parting lines. The design is more complicated and difficult to process. Generally, it depends on the product requirements. Sluice system.

 (3) Hot runner mold: This type of mold structure is basically the same as the fine water nozzle. The biggest difference is that the flow channel is in one or more constant temperature hot runner plates and hot nozzles, no cold material release, flow path and pouring. The mouth is directly on the product, so the flow channel does not need to be demoulded. This system is also called the waterless mouth system, which can save raw materials, is suitable for the case where the raw materials are expensive and the product requirements are high, the design and processing are difficult, and the mold cost is high.


  The hot runner system, also known as the hot runner system, is mainly composed of a hot sprue bush, a hot runner plate, and a temperature-controlled electric box. Our common hot runner systems are available in single-point hot gates and multi-point hot gates. The single-point hot gate uses a single hot sprue sleeve to directly inject molten plastic into the cavity. It is suitable for plastic molds with a single cavity and a single gate. The multi-point hot gate branches the molten material to each through a hot runner plate. The hot runner is re-entered into the cavity, which is suitable for single-cavity multi-point feeding or multi-cavity molds.

What factors will effect the the price of injection molds  ?

    Injection molds are important process equipment for the production of various industrial products. With the rapid development of the plastics industry and the promotion and application of plastic products in the aviation, aerospace, electronics, machinery, shipbuilding and automotive industries, the more demanding the products are. The higher the value, the factors that will affect the final price of the injection mold factory in the process of manufacturing injection molds?

  First, the product size, shape is simple and complex. This decision, the corresponding structure of the mold, directly related to the cost of the mold

   Second, the product's requirements for size and appearance, precision requirements, high appearance requirements, processing costs are not the same

   Third, the requirements for the number of  cavities of injection molding shot, , is one part or several parts at a time, this is generally not too very big product has this one and for the high volume mass production parts.

    Fourth, the expected amount of mold production, this determines what kind of  steel material to use, but also the cost.

   Fifth, the injection runner system-- cold or hot runner.   the hot runner is widely used for high technical or high material price components . it is very good solution to save the material cost and have better quality stability. but the hot runner will increase the mold total cost.
