Custom Silicone Parts Manufacturing Services

Temco Rubber manufactures custom silicone molded parts for OEM applications, from prototype development through repeat production. We work from 2D/3D drawings, physical samples, and performance requirements to select the appropriate silicone grade and molding process, including HCR compression molding and LSR injection molding. Our in-house tooling workflow helps shorten development cycles and maintain consistent part quality across production batches.

Silicone Molding Capabilities: HCR & LSR

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.

Silicone Molding Material Grades

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.

OEM Silicone Molded Parts: From Drawing to Repeat Production

Temco Rubber supports OEM buyers that need custom silicone parts developed around a real product, assembly, sealing interface, or mechanical requirement. We can review 2D/3D drawings, physical samples, target hardness, material requirements, tolerances, expected production volume, and any critical functional dimensions before tooling begins.

For companies comparing a silicone rubber parts manufacturer, the key question is not only whether a part can be molded, but whether the material, mold design, geometry, inspection plan, and repeat-production approach fit the application. Our workflow connects tooling and molding decisions so custom silicone components can move from development into repeat supply with fewer avoidable handoffs.

Drawing or Sample ReviewStart from CAD data, technical drawings, an existing sample, or a combination of these inputs.
Material & Hardness SelectionDefine silicone grade, Shore A range, color, and application requirements before production approval.
Molded-Part DFMReview wall sections, parting lines, undercuts, tolerances, and demolding considerations before tooling.
Prototype to Repeat ProductionUse first samples to confirm agreed fit, dimensions, appearance, and functional requirements before recurring orders.

What to Include in an OEM Silicone Parts RFQ

  • 2D drawing and/or 3D CAD model
  • Physical sample if available
  • Target silicone grade and Shore A hardness
  • Critical dimensions and tolerances
  • Operating environment and functional requirements
  • Expected prototype and production quantities

OEM Buyer Guide

Buyer Guide for Selecting a Silicone Manufacturing Partner

Choosing a silicone supplier involves more than comparing unit prices. Engineering support, silicone material knowledge, tooling capability, molding-process selection, first-sample validation, inspection, and repeat-production control can all affect the long-term success of an OEM project.

If you are comparing suppliers before starting tooling, read our guide on how to choose a silicone parts manufacturer before making a sourcing decision.

  • DFM and engineering support
  • Silicone material capability
  • Compression vs. LSR process selection
  • Mold design and tooling
  • First-sample validation
  • Quality and repeatability

Frequently Asked Questions

Find technical insights regarding custom silicone molding, material characteristics, and tooling setups from our engineering team.

What types of custom silicone parts can you manufacture? +
We manufacture a broad range of custom silicone components from customer drawings, 3D models, samples, and performance requirements. Typical projects include gaskets, seals, membranes, keypads, protective covers, tubing, bellows, bumpers, valves, and other molded OEM components.
What are the lead times for custom silicone tooling and prototypes? +
Lead time depends on part geometry, tool complexity, selected material, order quantity, and any testing or approval requirements. After reviewing your drawing or sample, Temco Rubber provides a project-specific schedule covering tooling, first-article samples, validation, and production.
Can you overmold silicone directly onto plastic or metal substrates? +
Silicone-to-plastic and silicone-to-metal overmolding can be evaluated depending on the substrate, silicone grade, bonding method, part geometry, and production process. Send us the substrate material and part drawing so our team can review bonding feasibility and recommend an appropriate manufacturing approach.
What should I send for an OEM silicone parts RFQ? +
Send a 2D drawing or 3D CAD model when available, along with material or hardness requirements, critical dimensions, the operating environment, expected production quantity, and any functional or inspection requirements. A physical sample can also be reviewed when the original drawing is unavailable.
