Rubber and silicone are widely used for molded components, but each material offers different performance characteristics. Temperature exposure, chemical resistance, mechanical stress, production volume, application requirements, and budget can all affect material selection. Advanced Prototype Molding provides molding solutions for both materials, supporting projects from prototyping and pilot runs to production. Comparing custom rubber parts with silicone parts can help you determine which material and molding process fit your project requirements.
Custom rubber parts are molded components produced from different rubber formulations based on the required application. Advanced Prototype Molding works with materials including natural rubber, silicone, Viton, EPDM, BUNA, and neoprene.
Rubber is well suited to applications that require tensile strength, tear resistance, impact absorption, vibration damping, or abrasion resistance. Common applications include automotive systems, fuel and electrical systems, HVAC equipment, hydraulic and pneumatic seals, O-rings, sterile hoses, and other industrial components.
Custom silicone parts provide flexibility and strong performance in demanding environments. Silicone offers high-temperature resistance, chemical stability, UV and ozone resistance, biocompatibility, and insulating properties. It can also remain flexible in cold conditions.
Advanced Prototype Molding produces silicone components for medical devices, electrical connectors, seals, cookware, gaskets, valves, and functional prototypes. Silicone can perform at temperatures as high as 230°C (450°F) and is also suited to applications involving healthcare and food-related requirements.
Silicone and rubber each have characteristics that fit different applications. Silicone performs well under high temperatures and exposure to UV and ozone while maintaining flexibility over time. Rubber can provide stronger tensile and tear resistance for parts exposed to repeated flexing or mechanical stress.
Cost is another consideration. Silicone typically costs more per unit, while rubber can provide a more economical option for many high-volume applications. Selecting the material based on actual operating conditions can help avoid unnecessary material costs and premature replacement.
Key considerations include:
Advanced Prototype Molding uses liquid silicone rubber (LSR) molding and rubber compression molding. LSR combines a two-component compound before injection and heat curing with a platinum catalyst. CNC-machined molds capture design details and can be reused for production. LSR supports functional prototypes, bridge tooling, pilot runs, low-volume production, and high-volume production.
Compression molding uses uncured rubber, heat, and pressure to form finished components. It offers simpler and faster tooling, lower tooling costs, precise parts, and low material waste. APM also provides injection molding and urethane casting, processes that can support efficient manufacturing and the use of recyclable materials.
Start with the part's operating requirements. Silicone may fit applications involving high temperatures, UV exposure, biocompatibility, sterilization, or chemical resistance. Rubber may be appropriate where mechanical stress, abrasion, impact absorption, vibration damping, or cost are priorities.
Production volume, part complexity, material requirements, budget, and tooling time should also factor into the decision. Advanced Prototype Molding can help assess these requirements and identify an appropriate molding process.

Injection molding is widely used for rapid prototyping and production of plastic, urethane, or metal components. There are multiple types of injection molding processes, each using different materials and molds.
Advanced Prototype Molding is capable of producing epoxy, aluminum, and steel molds. Each option has its own advantages. Our service includes finding the mold best suited for the project.
Injection molding is the manufacturing technique wherein a mold is filled with a molten or melted filling material which is then cooled to produce a solid component. The material is first melted and mixed in a heated barrel, then injected under pressure into a mold where it will cool and take on the shape of the inside of the mold.
The injection molding process enables the fabrication of many parts with stringent specifications. It is necessary to have a well-designed, durable mold to achieve the level of precise repeatability necessary for large production runs. The melt flows into the mold through gates and the displaced air escapes through vents. Improper gate design will cause air to partially fill the mold, causing misshapen parts. If the vents are too small or positioned incorrectly, air bubbles may get trapped in the product or cause burn spots.
A successful injection molding operation also depends on the material used. Materials must be selected with the right mechanical properties – such as hardness, flexibility, and density – that is appropriate for the application. The cost of the material is also important for many designs, as the prohibitive cost may make a product or design unfeasible.
The most common materials used for injection molding include Acrylonitrile Butadiene Styrene (ABS), Polycarbonate (PC), ABS and PC blend, High-Density Polyethylene (HDPE), Polypropylene (PP), and Nylon (polyamide) as provided in the image below.
The type of injection molding process used depends on the material. These processes include:
Plastic injection molding typically uses some type of thermoplastic. Molding with plastic is suitable for prototyping, production, and small runs. Plastic resin pellets are melted, injected into the mold, and cooled to form the final part shape.
Liquid silicon rubber (LSR) molding uses thermoset materials. Two different chemicals are mixed to make the thermoset LSR. The LSR injection system is cooled but the mold is heated. Since LSR is a thermoset material, the molded part cannot be reused. LSR is also useful for prototyping and small part runs.
Die casting uses molten metal for manufacturing durable metallic parts. Die casting is employed for making large numbers of metallic parts. A variety of metals may be used in die casting, including aluminum, copper, magnesium, or zinc.
Advanced Prototype Molding (APM) excels in building epoxy, aluminum, and steel molds to your specifications. Epoxy is a strong, tough, yet inexpensive material for making molds. In most cases, aluminum is used instead of steel for making molds due to faster turnaround times and lower costs. However, stainless steel is still the mold of choice when highly polished cavities are required, as in the case of medical devices.
