RUNNER SYSTEM OF INJECTION MOLDS

When molten plastic material leaves the barrel through the nozzle, it is guided toward the mold cavity, its final destination. Its flow path is called runner system, such as the sprue, runners, gates. The runner is in a simple direct route or goes through a series if turns that the flow molten material twists, and restrictions as it approaches the mold cavity. The molten plastic material flows into this cavity, takes the configuration of this chamber in the shape […]

Understanding with the injection molding process

With the use of injection molding presses and high-performance resins, plastic injection molders are able to craft a broad range of quality custom parts. Just as all resins are unique, these sophisticated machines offer varied capabilities and performance options depending on press size and type.
To ensure optimal quality and value, it’s critical to partner with a manufacturer who can provide the right size press for your specific needs.

Hot runner of injection mould

In order to simplify the injection molding process and reduce the waste of parts, it is important to eliminate the need for a large auxiliary cold runner. The key is to ensure that the melt remains molten throughout the flow channel system so that it does not solidify until it reaches the cavity wall where the cavity is cooled.

Internal heating hot runner:
The internal heating hot runner system is the first hot runner system to be put into the market. […]

Cold Runner of injection

The advantage of cold runner is that it is easy to use and can meet some aesthetic requirements. The cold runner reduces injection into transparent acrylic or polycarbonate parts used for light transmission, avoiding the visible banding effect of injection in some parts.

In addition to the waste of raw materials, the defects of the cold runner include adding steps to the whole automation or manual process. Removing the cold runner from the parts of the mold requires robots or […]

HISTORY OF PLASTIC INJECTION MOLDING

Plastic injection molding originated with chemists in Europe and The United States who were experimenting with plastics. Originally it was done by hand and pressed into a mold using Parkesine but it proved to be too brittle and flammable. John Wesley Hyatt is the official inventor of plastic injection molding and the process has a rich history with brilliant minds.
John Wesley Hyatt was a creative inventor and developed the processing of celluloid plastics. This was an amazing feat for […]

The process of injection

Tempreture  control
Barrel temperature: injection molding process to control the temperature of the barrel temperature, nozzle temperature and mold temperature. The first two kinds of temperature mainly affect the plasticization and flow of plastics, and the latter one mainly affects the flow and cooling of plastics. Each plastic has a different flow temperature, and the flow temperature and decomposition temperature of the same plastic vary depending on the source or brand, due to the difference in average molecular weight and […]

The definition and development of the injection mould

General definition of mould: in industrial production, metal or nonmetallic materials are made into parts or products of the desired shape by pressure with various presses and special tools mounted on the presses. The special tools are collectively called molds.
The injection process explains that the mold is a tool for producing plastic products. It consists of several parts, and the combination has a molding cavity. When injection molding, the mold is clamped on the injection molding machine, and the […]
