Seals & Packing
Moulded Parts
Custom Moulded Rubber Components
Diaphragms, bellows, bumpers, grommets, bushings, custom seal profiles. If it's rubber or polyurethane, we can mould it. Compression, transfer, or injection moulding depending on the geometry and run size. New tooling typically takes 2–4 weeks, but if you've got an existing part or sample, we can usually match it without starting from scratch.
Types & Variants
Diaphragms
Flat and rolling diaphragms for pumps, actuators, regulators, and pressure switches in rubber, silicone, and PTFE-coated fabrics.
Bellows & Boots
Protective rubber bellows and dust boots for steering linkages, ball joints, and actuator rods.
Bumpers & Mounts
Vibration-dampening mounts, buffers, and stop bumpers in natural rubber, neoprene, and polyurethane.
Custom Seals & Profiles
Custom seal cross-sections, grommets, bushings, and specialised shapes moulded to your specification.
Common Applications
OEM Replacement
Reverse-engineered parts when the original is obsolete or the OEM lead time is three months you don't have. We see this constantly with older European equipment.
Mining Equipment
Wear-resistant polyurethane liners, screen panels, and custom seals for crushers and screens.
Transport & Automotive
Suspension bushings, engine mounts, and protective boots for trucks, buses, and rail vehicles.
