Three Manufacturing Processes for Silicone Seals
Silicone seals are produced through three primary processes — Extrusion + Bonding, Molding, and Calendering + Die-Cutting. Each offers distinct advantages and limitations depending on your application requirements.
Extrusion + Bonding
14+ Extrusion LinesContinuous profiles of any cross-section, cut and bonded into closed rings via automated equipment.
✓ Advantages
No length limit · Low tooling cost · Any cross-section (D/P/E/U/custom) · No parting lines · Fast sampling 3-5 days · Cost-effective for small batches
✗ Limitations
Visible bonded joint · Joint tensile strength limited (1-10kg) · Seal integrity slightly lower than molded · Complex 3D shapes restricted
Molding
7 Molding LinesCompounded silicone is placed into a steel mold and cured under heat and pressure — the traditional method for complex shapes.
✓ Advantages
Complex shapes · No joints (molded as one piece) · High dimensional precision (±0.05mm) · Smooth surface finish · Ideal for small, intricate parts
✗ Limitations
High tooling cost ($500-$5,000) · Size limited by mold · Parting lines visible · Lower efficiency · Not economical for small batches · Cannot produce continuous lengths
Calendering + Die-Cutting
4 Calendering LinesSilicone is rolled into uniform sheets through heated rollers, then die-cut into flat gaskets and pads.
✓ Advantages
High thickness precision (±0.015–0.1mm) · Large sheet area · High die-cutting efficiency · Low cost for flat parts · Supports slitting, laminating, adhesive backing
✗ Limitations
Flat products only · High equipment investment · Cannot produce sealing strips with 3D cross-sections · Anisotropic properties (machine vs. transverse direction)
| Comparison | Extrusion + Bonding | Molding | Calendering + Die-Cutting |
|---|---|---|---|
| Products | Long seals, any-diameter rings | Complex shapes, precision parts | Flat sheets, flat gaskets |
| Tooling Cost | Low ($100-$500) | High ($500-$5,000) | Medium |
| Length / Size | Unlimited | Mold-limited | Sheet-limited |
| Cross-Section | Any (D/P/E/U/custom) | Any (complex 3D) | Flat only |
| Efficiency | High (continuous) | Low (batch) | High (die-cutting) |
| Joint / Parting Line | Visible bond joint | Parting line | None |
| Batch Economy | Small to large | Large only | Small to large |
| Best For | Long seals · any diameter rings | Complex parts · precision | Flat sheets · gaskets |
Extrusion + Bonding
Best for: Long sealing strips (doors, windows, cabinets) · Any-diameter rings · Cost-effective prototyping · Low to medium volumes
Molding
Best for: Complex 3D shapes · High-precision parts · No-joint requirements · High-volume runs where tooling cost can be amortized
Calendering + Die-Cutting
Best for: Flat silicone sheets · Gaskets · Pads · Large-area parts · High-volume production with uniform thickness requirements
