Custom Rubber Mold Manufacturing Services
Temco Rubber designs and manufactures custom rubber mold tooling for compression, transfer, and injection molding programs. We work from 2D drawings, 3D models, physical samples, rubber compound requirements, critical dimensions, and expected production volume to develop production tooling for molded rubber components.

Critical Engineering Tooling Standards
Reliable molded-part production begins with mold engineering. Tool configuration is reviewed around part geometry, compound behavior, cavity layout, parting lines, venting, demolding, and the intended molding process.
Shrinkage Calculations
Rubber shrinkage varies by compound, hardness, geometry, cure conditions, and molding process. Cavity dimensions are adjusted using project-specific material and sampling data rather than one fixed shrinkage value.
Strategic Venting
Improper venting accumulates trapped air, causing bu marks or voids. Our molds integrate strategic micro-channels and venting bridges to allow air escape during material injection.
Flash & Parting Line Control
Land design and parting-line placement are reviewed to manage flash-sensitive areas and support practical deflashing according to the agreed part requirements.
In-House Tooling & Machining Division
Our tooling workflow includes CNC and EDM machining for mold cores and cavities. Steel selection and machining strategy are matched to the mold design, production method, cavity count, and expected service requirements.
- Tool-steel selection matched to mold design, expected volume, and production conditions
- Cavity surface finishing selected according to release, appearance, and part requirements
- Runner-system concepts reviewed according to the selected rubber molding process
- Modular tooling concepts can be evaluated where interchangeable inserts are useful
Engineered Mold Classifications
We design molds around the intended press system, molding method, expected volume, and part requirements to balance tooling complexity with production needs.
Compression Molds
Compression molds use pre-formed rubber compound placed into heated cavities and are often practical for larger parts, thicker sections, and low-to-medium production volumes.
Transfer Molds
Transfer molds use a transfer chamber and closed cavities, making the process suitable for selected detailed geometries, insert-molded parts, and rubber-to-metal component designs.
Injection Molds
Injection-mold tooling can use multi-cavity layouts, runner systems, gates, and process-control features selected for higher-volume production and repeatable molded-part geometry.
