What we do in-house, and what we do not
What We Can Actually Do
Supplier websites rarely publish manufacturing detail, which leaves the buyer guessing. This page is the honest version: what we run, what we outsource, and where the limits are.
Silicone Molding
Compression and liquid silicone rubber (LSR) moulding for solid silicone parts from prototype to series production.
Compression Molding
The primary process for solid rubber and silicone parts: thick sections, medium-to-high hardness, low-to-mid volumes.
Custom Tooling
In-house mould design and tooling, with the tooling cost refundable against volume production.
Full Capability Matrix
| Capability | Status | Typical application | Notes |
|---|---|---|---|
| Mould/tooling design | In-house | All custom parts | We design the tool, not just fill it. |
| Compression moulding | In-house | Gaskets, seals, feet, dampers, thick sections | Best cost point for solid silicone/rubber at medium volume. |
| Liquid silicone rubber (LSR) | In-house | Thin-wall, high-precision, optically clear | Preferred where fatigue life and precision dominate. |
| Rubber compounding | In-house | EPDM, NBR, FKM, NR, SBR, CR | Compound selected against your service conditions. |
| Prototyping | In-house | Design validation before tooling | Short-run and sample parts for fit and function testing. |
| Deflashing & finishing | In-house | All moulded parts | Critical for sealing faces and cosmetic surfaces. |
| Screen printing & laser marking | In-house | Keypads, branded parts | Custom graphics, legends and traceability marks. |
| Bonding & sub-assembly | In-house | Silicone-to-metal, silicone-to-plastic | For parts shipped ready to fit. |
| Injection moulding | Partner network | High-volume rubber parts | Managed and inspected by us; tooling remains under our control. |
| Overmoulding | Partner network | Rubber over substrate | Quoted case by case against your substrate and volume. |
Process Control
The chain we manage for every programme, from first enquiry to repeat order:
- Drawing and specification review by an engineer.
- Material selection proposal with the reasoning stated.
- Tooling design and, on approval, tool manufacture.
- First-article samples for your fit, function and life testing.
- Approval, then locked process parameters for production.
- In-process and final inspection with records shipped with the parts.
- Repeat production against the approved reference sample.
Where the part is a robot joint seal the chain above is unchanged, but the acceptance criteria tighten: compression set, ozone exposure and cyclic articulation have to be specified at quote stage rather than discovered in the field. We set that out in silicone seals for robotic joints.
What We Deliberately Do Not Claim
- We do not claim IATF 16949, medical device registration or aerospace approvals.
- We do not claim a factory size, machine count or headcount we cannot evidence.
- We do not quote lead times as a fixed number independent of your part.
- We do not hold stock of generic parts and we do not resell other factories' catalogues.
