injection Molding rubber 

When we are writing about injection molding rubber we need distinguish rubbers  in 3 main material groups;

1. injection molding natural rubber.
2. Liquid silicone rubber.
3. synthetic rubber or thermoplastic rubbers a.k.a TPR

we discuss first natural rubber molding and than synthetic thermoplastic rubber molding.

What is natural rubber?

Natural rubber is produced by latex trees and latex is produced by the rubber tree in countries such as Thailand and Vietnam;

The latex tree produced sap, a milky white translucent liquid,  that is collected. After collection at the tree in cups, which we call tapping ( cut the tree and than the tree bleeds the sap) , the coagulation process starts..this is when an acid is added tot the mix, and this mix is pressed true rollers , so the water will removed out of it. this is called calendaring,After this process the rubber will be dried and ready fro further processing.

What is liquid silicone rubber?

LSR – liquid silicone rubber molding

Here, silicon rubber is used for liquid injection moulding. The silicon fluid remains in an inert state until it is mixed with agents which would activate it when it is finally heated or vulcanized. Sometimes this process is calles LIM, liquid injection molding.

There are numerous medical parts and equipment which need precision created rubber injection moulding products. There are also a lot of auto parts which make use of this technique to guarantee that the vehicles manufactured are up to the standards which they have been designed to be. Only with the injection moulding process can the vehicle parts be clones of one another. This makes it easier for the maintenance of the vehicles which may need to have replacement parts.

The rubber injection molding is also the process used to create the replacement parts of many mechanical tools and equipment used everyday like kitchen gadgets and carpentry tools. This is the only way that will guarantee the tools and equipment can be used for years and years.

Injection moulding is a technique used for the production of parts from thermoplastic and thermosetting plastic materials and silicone materials. These materials are fed into a heated tube, mixed and then forced into a mold cavity where it is allowed to cool down and harden following the contours of the mould.

Once a product is designed and engineered, the molds are going to be made by a toolmaker or a mold maker. The materials used for the molds include steel and aluminium.

There are also precision made molds used for medical injection moulding which could create body parts and medical tools and equipment.

Rubber injection moulding is also used to create rubber parts which are commonly used in mechanical parts and machines. The machines used to create these products are usually found in a press shop or in industries which manufacture rubber parts.

The difference between rubber injection moulding and other injection molding china by Triple-c processes is the use of the different materials.
