Custom Silicone Molded Parts
We'll help choose the best silicone molding process for you based on the part performance properties needed, quantities, size of the part, and cost. We aren't limited in how we approach your project because we have all silicone molding technologies in house. We match the custom silicone molding process to best match the custom molded part you are desiring to have molded.
Liquid Injection Molding (LIM) Silicone MoldingRubber Industries Liquid Injection Molding capabilities include Liquid Silicone Rubber (LSR) process technology for both clear and colored silicone parts, which provide an expanded option to our current customers and to new prospects.
Click here to see sample parts. LSR is a name for a range of two-component Liquid Silicone Rubbers used to produce elastic parts by injection molding. Because of its high thermal stability, good rubber-like properties and resistance to aging, LSR is the material of choice by many designers in automotive, electronics, appliance, medical and textile industries. The material has a wide temperature range (-94 degree F to +400 degree F) with low compression set and resistance to the damaging effects of sunlight and ozone. Typical LSR designed components include seals, insulators, diffusers, valves, gaskets and bellows -- to name just a few. Rubber Industries utilizes a dedicated, clean environment in order to appeal to the clean manufacturing requirements of various customers including medical device manufacturers of non-implantable custom molded parts and assemblies. Rubber Industries is more competitive than other molders because of less overhead.

Silicone Custom Molding
Background on Silicone and use in custom molded parts
Silicone is a synthetic rubber-like material that has an extensive range of applications. This versatile material is normally heat-resistant, water-repellent and thermally stable. It has low toxicity, will not support the growth of microbes, has low thermal conductivity, and can be formulated to either conduct electrical currents or insulate against them. Silicone adheres remarkably well to some substrates, but it will not stick to others. Furthermore, it is resistant to ultraviolet lights, ozone and oxygen. Because silicone has so many advantageous properties, it is widely used in numerous industries, including the consumer goods, medical, automotive, aerospace, industrial and culinary sectors.
At Rubber Industries, we offer the fastest complete silicone services from proto to production and the fastest silicone production tooling. Whether you need overmolded parts, custom colors, custom silicone formulas or dual durometer materials in high volume or low volume production runs, we can help.
• Seals: High-quality seals are especially critical in the automotive and aerospace industry as well as in the manufacture of certain household items.
• Gaskets: Gaskets are widely used in many industries. For example, they can be found in automobile engines, pumps and transmissions as well as in a variety of household appliances.
• Diaphragms: Diaphragms control the flow of gas or liquid between two locations. They are extremely common in industrial pumps and equipment.
• Bellows: Bellows come in a wide range of sizes and are used in various industries. They are common components in automobiles, medical equipment, light rail vehicles and manufacturing equipment.
• O-rings: O-rings can be used in dentistry, construction, aerospace or for any static application involved exposure to petrochemicals, water or steam.
• Overmolded Parts: Overmolding is a technique used to bond one material to another. Custom silicone to metal bonded applications are used for a variety of purposes, including encapsulating medically implanted electronic devices, creating slip-resistant handles for tools, and insulating electrical circuitry.
• Dual Durometer Products: Dual durometer means that the material has two hardness characteristics. Numerous consumer products feature this technique, including some squeegees, golf club grips, keypads and replacement windows.

Experience Producing Many Items
We are capable of producing almost every kind of rubber item. We are very skilled at producing strong yet flexible items including:
- Seals
- Gaskets
- O-rings
- Bellows
- Diaphragms
- Grommets
- Ear pieces (dual durometer)
These are some of the most common and useful rubber items with them featured a vast number of items. The process of making seals, gaskets, O-rings, bellows, and diaphragms can be difficult as these items generally sustain a lot of wear and tear while needing to maintain their flexible structure. We do this by using high-quality silicone that can maintain exact dimensions despite years of use.
Overmolding
Our custom silicone to metal bonded overmolded process is a way to produce items where two very different materials are attached together. We do this by firmly attaching our custom silicon parts to metal and other materials during the molding process. Our Custom silicone to metal bonded overmolded process is very useful in industries such as the medical field as it allows doctors to protect delicate electronic items from corrosive materials and the body's immune system.
Dual Durometer
Our team sets itself apart being experts at the dual durometer process. This process involves binding a rigid material such as metal to rubber. This means that we can produce a part that have the properties of both, or one that is able to protect the other items it makes contact with by having a rubber coating. Our dual durometer technique means that our customers can have items where both the rubber or metal parts will not wear out.
Custom Colors
Our team of chemists can produce rubber that is of a certain specific colors. This means that our customer have access to rubber looks good, can be exposed on consumer items, and does not need to be painted or dyed. In addition, the ability to have custom colors on rubber items makes it easy for repairmen to identify different rubber items.
