Why Choose Compression Molding for Automotive Door Seals?
✔️ Lower tooling cost
Cheaper molds than injection molding, ideal for small to medium volumes.
✔️ Handles complex 3D shapes
Can mold curved, one‑piece seals that extrusion can’t do.
✔️ Low material waste
Only minimal flash to trim.
✔️ Durable parts
Dense, void‑free seals with excellent weather and ozone resistance (especially EPDM).
✔️ Flexible
Allows metal inserts, different rubber hardness zones, or integrated clips.
✔️ Quick changeover
Easy to switch molds or materials for different part numbers.
