A product success, the most important must be the product design, followed by the mold design, and then mold manufacturing, injection molding production.
Plastic injection mold is a tool for the production of plastic products, it gives the products complete structure and exact size. Injection mold, along with
Injection molding is the most commonly used manufacturing process for the fabrication of plastic parts. A wide variety of products are manufactured using injection molding, which vary greatly in their size, complexity, and application. The injection molding process requires the use of an injection molding machine, raw plastic material, and a mold.
Hot runner technology is an advanced technology used in plastic injection mold runner system. The so-called hot runner injection molding machine nozzle is defined from the gate to the plastic always remains in the molten state in each mold without curing as waste removal, melt retention in the gating system can be in again when the injection is injected into the cavity.
Although the structure of the plastic mold may varies due to many factors, such as the variety and performance of resin material, shape and structure of plastic molded parts, type of injection molding machine, etc, the basic structure is the same. The mould is mainly composed of gating system, temperature control system, molding parts and structural parts. Gating system and molding parts are in direct contact with the plastic parts. The two parts are the most complex in injection mould system, which required highest accuracy and smoothness…..
