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 […]

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 […]

Working conditions of plastic Mould

Due to the development of plastics and plastic molding industry, the quality requirement of plastic mould is more and more high, so the problem of plastic mold failure and its influencing factors have become an important research topic. The main working parts of plastic moulds are molding parts, such as convex dies, concave dies, etc. They form the cavity of plastic molds, which form various surfaces of plastic parts and are directly in contact with plastics, subjected to pressure, […]

The status of Mould in processing Industry

A mold is a tool that uses its particular shape to shape a product of a certain shape and size. A variety of molds are widely used in various material processing industries. For example, the sand or die-casting mould used in metal casting, forging die for metal pressure processing, cold die and so on.
The overall requirement of the mould is that it can produce the public products which meet the requirements in dimension precision, appearance, physical properties and so […]

The advantage and defect of plastic

Advantage:

Most plastics have strong corrosion resistance and do not react with acids or bases.
Low cost of plastic manufacturing
 Durable, waterproof, light weight.
Easy to be molded into different shapes.
Is a good insulator.
Plastics can be used to prepare fuel oil and fuel gas, which can reduce crude oil consumption.

Defect:
1. Recycling waste plastics, classification is very difficult, and not cost-effective.

Plastics burn easily and produce toxic gases when they burn. For example, when polystyrene burns, it produces toluene, a small amount of this substance […]

PLASTIC INJECTION MOULDING DESIGN PROCESS AND TOOLING

Plastic is a very versatile material and it’s finding uses in all areas of our lives. Many of us don’t even appreciate fully how much we benefit from this invention nowadays, but there are people among us with a very real appreciation for plastic’s benefits and flexible applications. If you’ve ever done a DYI project that required some specifically molded parts, for example, you’ve likely come to appreciate the usefulness of plastic quite a lot.
What is  plastic injection moulding:
Plastic […]

Main Properties of Plastics

There are some properties of plastic as follows:
1. Most plastics are light, chemically stable and do not rust
2.Good impact resistance
3.Good transparency and wear resistance
4.Good insulation, low thermal conductivity
5.General formability, good coloring, low processing cost
6.Most plastics have poor heat resistance, high thermal expansion rate and easy combustion.
7.Poor dimensional stability and easy deformation
8.Most plastics have poor low temperature resistance, brittle at low temperature and easy to aging.
9.Some plastics are soluble in solvents

Plastics can be divided into thermosetting and thermoplastic, the former […]

With the rapid development of Chinese economy, the requirement of plastic mould industry is becoming more and more strict, so it provides a huge power for the development of plastic mould industry. According to accurate statistics, the annual output value of plastic molds in China reached 53.4 billion RMB, which is an existing fact.
With the rapid development of automobile manufacturing and IT manufacturing, […]

JASONMOULD TELLS EVERYTHING YOU NEED TO KNOW ABOUT INJECTION MOLDING

What is injection molding:
Injection molding is a fast and efficient manufacturing process for producing a wide range of parts or components in large volume. It is most typically used in mass-production processes where the same parts in being created thousands or even millions of times in succecssion.

General definition of injection mold: 
During the commercial production process, metal materials or non-metallic materials are processed into variety of shapes and structures by pressure through the press machine and the special tool attached […]
