Silicone Injection Molding and LSR Molding

What is Injection Molding of Silicone?
Silicone injection molding is a manufacturing process developed for the molding of plastics, while injection molding of silicone rubber began in the 60's and 70's. Injection molding successfully alters the process by heating the silicone rubber and placing it under significantly more pressure per square inch of cavity surface in the custom silicone molding process. This is different from the plastic injection molding process. Through various innovations, injection molding has become one of the most efficient ways to create custom silicone molded products.
First, a little background on Rubber Industries, Inc
- Celebrating 50 years so you can count on us for your project now and into the future.
- We've invested millions in our USA plant in just these last four years to better serve you.
- Continuity of ownership leads to consistency in quality, service, and pricing.
- We are the fastest in the industry from CAD to tooling to production.
- For example: we've made production tooling and shipped 10,000+ custom silicone parts in one week. We designed and programmed, cut steel into a 19" x 23" custom multi-cavity tool, and custom molded all in 7 days.

Silicone Injection Molding Advantages
The process of injection molding starts with efficient material preparation. To begin, the material is mixed in bulk and then prepared in various ways for injection molding, but it isn't stripped, but rather put in large sizes of up to a few pounds each that are put in a "stuffer" on the injection press.
Advantages:
Advantages:
- Silicone rubber has unique properties and has capabilities that other elastomers don't, but it can be more expensive per pound so the process of silicone injection molding helps reduce the waste of custom molded silicone compared to other processes.
- The complete elimination of pre-forms. The production and need for pre-forms is a labor intensive step that can potentially affect the finished product through variability in pre-form weight and shape.
- Elimination of operator placement of pre-forms. Since pre-forms are eliminated, the need for operators to place the pre-forms in a cavity (compression molding) or pot (transfer molding) is removed.
- Injection screw pre-heats material before forcing it into cavities. This process decreases the viscosity of the material, allowing it to flow more easily into the mold cavities. Pre-heating provides the potential for decreased cure times through more rapid cavity filling due to lower viscosity.
LSR (Liquid Silicone Rubber) Injection Molding
Silicone injection Molding advantages:
Rubber Industries can offer a variety of other silicone and custom molded rubber products through rubber compression molding and rubber transfer molding.
- Reduced cycle time
- Controlled Flash
- Economical process for high volumes of medium to high precision components
- Capable of producing overmolded components
- Minimal material waste
Rubber Industries can offer a variety of other silicone and custom molded rubber products through rubber compression molding and rubber transfer molding.

Custom Silicone Injection Molding Video
This video is of a custom molded silicone injection process. We (Rubber Industries) built the injection tooling in house. The silicone is a specially developed in house silicone formula to pass high temperature fire ratings in a specialized commercial application. We developed the tooling design, manufacturing process, and special performing silicone material, all on our 5 acre campus in Minneapolis, MN.

Custom Silicone Molding
Silicone Injection molding is very effective for medium and high volume custom molded silicone parts. Custom silicone parts are used in a variety of applications. Custom silicone gaskets, custom seals, custom handgrips, custom o-rings, and custom silicone molded parts are used in environments of high temperature applications where temperature resistance is key. Silicone is also excellent for resistance of environmental considerations like chemicals, ozone, etc. One other consideration for using silicone is the high quality color reproduction to match your project design.
At Rubber Industries we do custom silicone injection molding using both processes of HCR (High Consistency Rubber or gum stock) and liquid silicone rubber (LSR). Both processes utilize injection molding, but each of the rubber molds are built very differently to accomplish the final part.
We build all the tooling in our tool shop on site for our domestic projects, and we design the tooling specifically for the type of injection process used for both silicone and liquid silicone rubber.
The silicone injection molding process is used with both HCR (gum stock) silicone and also for LSR (liquid silicone rubber). Both of these processes use injection molding technology to increase throughput while minimizing waste. This helps lower per part price.
Silicone prototypes are commonly used to refine the design process (fit/form/function) and it is common for Rubber Industries to make a silicone prototype tool in just a few days including custom silicone parts.
