Supplier's Category: All Rubber & Elastomer Molding: Compression, transfer, and injection molding of rubber parts
Rubber and elastomer molding shapes rubber compounds into finished parts using compression, transfer, or injection molding — the three methods differing mainly in how the uncured rubber is loaded and moved into the mold cavity. It covers seals, gaskets, and flexible components across a wide hardness range.
The right molding method and compound depend on part geometry and the seal or flex performance required, so match the shop’s process to your part, not just its material capability.
- Ask which method fits your part: compression for simple shapes, transfer for moderate complexity, injection for high volume and tight tolerance
- Confirm compound experience with your required durometer, temperature range, and chemical exposure
- Check flash and parting-line control if the part has cosmetic or sealing surfaces

Where molded elastomers are used
Rubber and elastomer parts serve sealing and vibration-control roles across nearly every mechanical assembly.
- Automotive and industrial: seals, gaskets, and vibration-damping mounts
- Medical: silicone components requiring biocompatibility
- Electronics: gaskets, keypads, and environmental seals
