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 […]

SOMETHING YOU NEED TO KNOW ABOUT RAPID PROTOTYPING SERVICES

Rapid Prototype are needed for a number of reasons and in different sectors and rapid prototyping services are therefore very important in serving the needs of global customers. Customer concepts are brought to life by services such as 3D printing, pressure die casting, rapid plastic injection molding, rapid tooling and custom sheet metal fabrication among others. Companies that offer the services will in most cases also take up the modeling and drawing of the needed products before moving to […]

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.

ADVANTAGES OF RAPID PROTOTYPING

Rapid prototyping is a process of software development wherein physical objects are automatically constructed by means of SFF or solid freeform fabrication. In the process of rapid prototyping, a prototype or working model can be constructed quickly, and tested for its functionality, performance and output. The new features or ideas can be illustrated well in the prototype and early user feedback can be gathered with regards to the product.

Many companies have turned their attention to rapid prototyping for their […]

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, […]

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 […]

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 […]

PLASTIC INJECTION MOLDING SERVICES WIDELY USED IN VARIOUS INDUSTRIES

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. This is a process of manufacturing plastic by using thermosetting plastic and thermoplastic substance.
Plastic injection molding is commonly used for creating various parts of cars, from tiniest elements to the whole body components. This process involves […]

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 […]
