Benefits Of Two Shot Injection Molding

Overview
Imagine cutting your processing time in half. In some cases, that’s possible with two shot injection molding. Two shot injection molding is just what it sounds like – a way to produce two “shots” of something in one step.
The process involves producing two different components, from two different materials, and combining them in one process. This saves time over producing the two different components separately and saves money too since you don’t need to run the entire batch twice. What […]

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.

The main technical key points in the application of hot runner

A successful hot runner mold application project needs many links to guarantee. There are two most important technical factors. One is the control of plastic temperature, the other is the control of plastic flow.

1. Control of plastic temperature
The control of plastic temperature is very important in the application of hot runner mould. Many processing and product quality problems in the production process are directly due to poor temperature control of the hot runner system. For example, the quality of […]

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. […]

HOW ARE PLASTIC INJECTION MOLDING PRODUCTS MANUFACTURED?

Plastic is the most versatile material that is used in most applications today. The wide range used of this material has made a great impact in most industrial world. One of the processes in creating plastic product today is called plastic injection molding.
Plastic Injection Molding is a process that has been rapidly growing and which has brought in more momentum within a short range of time. The process of plastic molding injection brings about quite a few advantages. The […]

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 […]

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 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 […]
