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Reverse-engineered parts when the original is obsolete or the OEM lead time is three months you don't have.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.

Need Custom Moulded Parts?

Drawing, sample, or even a worn-out part we can measure up: any of those gets us started. Include the compound and hardness if you know it; if not, we'll recommend.
