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. […]
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 […]
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 […]
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 […]

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 […]
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 […]
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 […]
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 […]
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, […]
