OVERVIEW OF PLASTIC INJECTION MOLDING

Plastic injection molding is the method of manufacturing parts made of thermoplastic and thermosetting plastic by melting and forcing into molds where they cool to form the desired object.

Little history about Plastic injection molding
The injection molding process is not a new concept. It came into existence by 1872. By the introduction of plastic injection molding, the plastic industry saw multi-billion dollar earnings, with 32 % of all plastics, by weight processed by injection molding. This has made the plastic […]

Injection mould design

Economical Large Scale Manufacturing
Injection molded parts or finished products are increasingly popular in a variety of industries because the fabricating costs are relatively low after the initial engineering of the die is complete. This method of manufacturing also ensures that each individual part will exactly match every other piece; with the result being finely detailed parts manufactured that can be manufactured quickly in large quantities without losing details. There are many other advantages as well, including strength and durability […]

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 […]

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 […]

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 […]

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.
In […]
