Temco Rubber supports HCR compression and transfer molding as well as LSR injection molding to match part geometry, material requirements, tooling strategy, and production volume.
Liquid Silicone Rubber (LSR) Injection Molding
LSR injection molding is well suited for high-volume custom silicone parts that require consistent dimensions, fine details, and repeatable production. A two-component liquid silicone system is metered, mixed, and injected into a heated mold, making the process suitable for complex geometries, thin sections, and automated production. Temco Rubber uses LSR molding for OEM components where production consistency, dimensional control, and scalable output are important.
- Suitable for complex geometries and thin-wall silicone parts
- Consistent molding for medium- to high-volume production
- Supports automated and repeatable production cycles
- Suitable for precision OEM silicone components
HCR Silicone Compression & Transfer Molding
HCR compression and transfer molding are practical options for custom silicone parts with thicker sections, larger geometries, or low-to-medium production volumes. Pre-formed high-consistency silicone rubber is placed into a heated mold and cured under pressure, allowing flexible material selection, custom colors, and a wide range of part sizes and hardness levels.
- Cost-effective tooling for prototype and production programs
- Suitable for larger and thicker silicone components
- Supports a broad range of Shore A hardness levels
- Well suited for custom colors, keypads, seals, bellows, and industrial parts
Silicone Material Grades & Specifications
We process a range of VMQ silicone materials and select grades according to temperature, hardness, color, environmental exposure, and application requirements.
Medical & Healthcare Applications
Platinum-cured and application-specific silicone compounds can be selected for healthcare and medical-device components based on project requirements. Material selection can consider biocompatibility, sterilization method, temperature exposure, hardness, and mechanical performance where required.
Food & Beverage Applications
Food-contact silicone compounds can be selected for seals, gaskets, tubing, and other components used in food-processing and beverage equipment. Material selection is based on the required temperature range, fluid exposure, cleaning conditions, hardness, and applicable customer specifications.
Industrial VMQ Silicone
Depending on the selected compound, silicone materials can be specified for low- and elevated-temperature applications. Grade selection can also consider ozone, UV, weathering, electrical-insulation, and long-term environmental exposure.
Custom Hardness & Colors
Hardness, color, translucency, bonding behavior, and other material properties are selected according to the part design and application. Custom color matching and application-specific silicone grades can be evaluated during development.
Advanced CAD/CAM Engineering & Tooling
The performance of any custom silicone component begins with the engineering of its mold. At Temco Rubber, we maintain in-house tooling capabilities to help reduce communication delays and support faster prototype development.
Our engineering workflow uses CAD/CAM tools to review part geometry, parting-line strategy, cavity layout, expected material shrinkage, and manufacturability before tool production.
Through this integrated engineering workflow, dimensional targets are defined according to the customer drawing, selected material, and molding process. ISO 3302-1 can be used as a tolerance reference where applicable and agreed for the project, with inspection requirements defined before production approval.
