Product Description

1.Injection Molding Custom Rubber Parts- Molding Processes

Injection molding is one of the important manufacturing methods in rubber molding processes. The rubber is pre-heated before being injected into the mold. After pre-heated, the rubber flows more readily into the mold, allowing for higher cure temperatures, shortening the curing cycle. Rubber injection molding presses provide tight clamping, which results in little or no flash. We have injection machines with tonnage of 100 to 300 tons which can improve the compactness and functionality of products (especially the functionality of shock-absorbing products).


Advantages of Rubber Injection Molding

Fast production.

Low labor costs.

Can be used to produce very small parts.

Leaves little post-production scrap.

Good product consistency.

Reduced requirements for finishing.

Good dimensional control.


Disadvantages of Rubber Injection Molding

Small runs of parts can be costly.

Requires large production runs to really be efficient.

Not all compounds, or durometers, are suitable for this process.

High initial tooling and machinery cost.

Part design restrictions.


2.Application of Injection Molding Rubber Parts.

Rubber injection molding is an ideally suited for mid-to-high-volume production and where tight tolerances, part consistency or over-molding are required. It is widely used for the following products:

●Rubber boots

●Rubber gaskets

●Rubber seals

●Rubber grommets

●Colored rubber products

●Rubber bumpers

●Rubber grips

●Rubber diaphragms

●Rubber bellows

●Rubber shock absorbers

●Rubber to metal bonding products

●Complex rubber products

●Vibration control parts / vibration isolation parts

●Chemical or corrosion resistant parts

●Abrasion-resistant parts

●Custom rubber parts
