A single fundamental rule of injection molding is that hot material enters the mould, where it cools rapidly by cooling channels in the mold to a heat at which it stiffens enough to keep the pattern of them. The heat of the plastic mold tooling is for that reason important as it governs a portion of the general molding cycle. While the melt runs more freely with a hot injection mould tools, a better cool period is required in advance of the solidified molding can be ejected. Alternatively, while the melt stiffens quickly in a cold tool, it might not exactly achieve the extremities of the cavity. A compromise among the 2 opposites […]

What is a Polycarbonate (PC) Injection Moulding?
Silicone rubber is made up primarily of sand or silicon dioxide. Not beach sand of course but a specialty type of sand. This is not to be confused with other types of rubber. Liquid silicone rubber or LSR as it is sometimes referred to is a specialty type of compound. It is often used for plugs, seals and other products where flexibility and toughness are important. Of course, resistance to heat is often a critical reason why LSR molding is used.
The liquid silicone rubber molding process is very exact and a very specialized area. It is similar to injection molding but not exactly the same. The silicone is formed rather than extruded.
In many ways, it has […]
Mould, indispensable in modern industry development and technological level improvement, is one kind of widely-used process equipment during mid-period of industrial production. According to statistics, moulding accounts for 75% of rough machining of industrial parts and 50% of precision machining. Mould can be classified as cold-punching mold, injection mold (or plastic injection mold), die casting mold, rubber mold and so on.

How much does Plastic injection moulding cost?
The most commonly asked question in the molding industry is, “How much shall it cost to do plastic injection molding“? Well, the answer to this question largely depends on several factors, especially for the fact that plastic mold production has the highest upfront cost in all of the injection molding types

Mold Parting Line and Gate in Plastic Injection Mold
In Injection Molding (or almost in any type of molding), one of the most basic concepts is Parting line. A Mould is divided into two parts (more for complex designs) so that it comes apart in order to remove the product and reuse it again and again. These two parts are, namely, Core and Cavity. While doing injection molding the cavity needs to be placed inside the core before pouring the molten plastic in. The line where these two parts meet is called the mold parting line. The component produced thus has a single continuous line around its perimeter. This line is usually visible […]
