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 […]

The History of injection & Injection Molding

In 1868, Heyat developed a plastic material called celluloid. Celluloid was invented by Alexander Parks in 1851. Hyatt improves it so that it can be processed into finished shape. Hyatt and his brother Isaiah, in 1872, registered the patent for the first plunger injector. This machine is relatively simple than that used in the 20 th century. It basically works like a giant hypodermic syringe needle. The giant needle (diffuser) injects plastic into the mold through a heated cylinder.
In […]

EIGHT DEVELOPMENT TRENDS OF CHINA MOULD INDUSTRY

What is a mould? It is a pattern or tool of the product by the means of injection, blowing, ejection, casting, punching and so on in the industrial production. Chinese mould industry gained gratifying achievements in adjusting the industrial structure and implementing industrial upgrade. The quick development of the mould industry gives hope to many mould enterprises. But it is a pity that Chinese mould industry can not get rid of low-end market positioning. How to speed up the replacement […]

Eight categories of injection Mould

When the single parting surface injection mould is opened, the moving die and the fixed die are separated, and the plastic parts are taken out, which is called the single parting surface mould and the double plate mould. It is the simplest and most basic form of injection mould. It can be designed as a single cavity injection mould or a multi-cavity injection mould according to the need. It is the most widely used injection mold.
The double parting surface […]

PLASTIC INJECTION MOULDING SERVICES ARE WIDELY AVAILABLE FOR YOU TO FIND WHAT YOU WANT

If you consider the everyday things we take for granted you will be amazed at how many of them are products of plastic injection molding in one way or another. The plastic bottles we use for drinks, the model kits we built as kids. The mobile phone, that we all carry, have their bodies molded, and so it goes, all forms of plastic container, plastic garden chairs. These are all things we take for granted. The packaging industry depends […]

Injection molding parameter

1、Injection pressure
Injection pressure is provided by the hydraulic system of the injection molding system. The pressure of the hydraulic cylinder is transferred to the plastic melt through the screw of the injection molding machine. The plastic melt is pushed by the pressure, and through the nozzle of the injection molding machine, it enters the vertical passage of the mold. And through the gate into the mold cavity, this process is the injection molding process, or called the filling process. […]

CONSIDERATIONS FOR PLASTIC INJECTION MOLDING COMPANIES

Plastic injection molding is a popular manufacturing process where parts are made through the injection of plastic into molds. The process involves the feeding of the plastic into a heated barrel, mixing it up, and forcing it into the mold cavity. It is then left to cool and harden. In recent years, mold companies are facing the reality of global financial crisis and meet some other challenges. It is suggested that they should make analysis on the situation, develop strategies, […]

CLASSIFICATION OF INJECTION MOULD

Injection molds are divided into thermosetting plastic molds and thermoplastic molds according to their molding characteristics, and according to the molding process, they are divided into transfer moulds, blow moulds, casting moulds, thermoforming moulds, hot-pressing moulds (pressure-moulding moulds, injection molds, etc.),The hot pressing die can be divided into three types: overflow type, half overflow type and no overflow type. The injection mould can be divided into cold runner mould and hot runner mold by pouring system, and can be […]

Classification of plastic moulds

According to the different molding methods, we can divide different types of plastic processing mould corresponding to different process requirements, mainly including injection mould, extrusion mould, plastic suction mould, high foaming polystyrene mould and so on.
1.Plastic injection mould
It is mainly a kind of molding mould which is widely used in the production of thermoplastic parts. The corresponding processing equipment for plastic injection mould is plastic injection molding machine. The plastics are first heated and melted in the bottom heating […]
