Key Manufacturing Advantages
- Zero Tooling / Mold Cost: Proprietary 3D moulding and extrusion technology eliminating initial metal mold tooling expenses for custom rubber parts and profiles.
- Reverse Engineering: 1:1 vector scale technical drawings generated from physical samples, worn parts, or photos via instructions page.
- No CNC Turning Policy: Manufactured strictly via 3D moulding, compression moulding, and extrusion. CNC turning of seals is not performed.
- Pure Elastomers Only: Strictly pure elastomeric components. No fabric-reinforced rubber, no metal-reinforced rubber moulding, and no porous or sponge rubber.
Product Portfolio
- Hydraulic & Pneumatic Seals: Rod & piston seals, Chevron packing sets, Polypak, Kantseal, custom wipers.
- O-Rings & Custom Rings: Standard & oversized solid-cast O-Rings, X-Rings, Q-Rings from 6mm to several meters in diameter.
- Polyurethane Vibration Mounts: Shock absorbers, energy storage mounts, coupling inserts, spider gears.
- Rubber Bellows & Dust Covers: Custom protective bellows for cylinder rods, leadscrews, and expansion joints.
- Extrusion Profiles & Grommets: Custom profiles, cable entry grommets, and electrical insulation boots.
- Heavy-Duty 3D Moulding: Parts from 100g to massive industrial components exceeding 100kg and up to 12 meters.
