Mechanical function & protection

• Reduce vibration and noise: the overmolded plastic layer provides damping, anti-vibration, and noise reduction during operation.
• Corrosion resistance: prevents direct contact between metal and humid/chemical environments.
• Electrical & thermal insulation: ensures safety in electronic or high-temperature environments.
• Less wear: protects the metal surface from impact or direct friction.

Improved ergonomics & aesthetics

• Better grip: plastic increases friction and prevents slipping for handles, knobs, levers…
• Enhanced appearance: allows color combinations and smooth, glossy, or matte finishes as required.
• Flexible design: easy to form complex shapes, logos, or textures on the overmolded plastic.

Common applications

• Automotive: rubber/plastic over bushings, control arms, handles, seals, engine mounts.
• Electronics & appliances: handles, housings, control knobs.
• Industrial tools: grips, tool handles, shock pads, rollers.
• Medical & consumer: handheld devices, safety items, anti-slip products.

Vibration and noise reduction; impact resistance

• Rubber absorbs shocks, so when overmolded on a metal core it helps:
• Reduce vibration for high-speed machinery.
• Limit noise during operation.
• Protect metal parts from deformation upon impact.

Applications include industrial wheels, shock-absorbing pads, flexible couplings, machine mounts.

Wear resistance and longer life

• The rubber layer protects the metal surface from friction, corrosion, chemicals, or harsh environments (humidity, salt, acids, alkalis...).
• Extends the life of parts frequently exposed to mechanical or chemical contact.

Widely used in chemical hoses, rollers, tanks, impellers, conveyor liners.

Higher friction & motion control

• Rubber has a high coefficient of friction, so the overmolded layer helps:
• Better power transmission (especially in rollers, calender rolls, pulleys...).
• Prevent slipping or shifting during operation.

Common in printing rollers, conveyor rollers, paper press rolls, draw rolls.

Electrical & thermal insulation; leak prevention

• Rubber is a good electrical and thermal insulator, so when overmolded on metal it helps:
• Block electricity or heat from passing through the metal.
• Increase safety in environments with electricity, steam, or high temperature.

Waterproofing and surface protection

• Rubber over metal creates a sealed layer that prevents the ingress of water or gas.
• Used for gaskets, seals, valves, flanges, tank linings, pipelines.

Common applications

• Mechanical industry: calender rolls, wheels, shock-absorbing pads.
• Chemical industry: tank linings, pipe linings, anti-corrosion coatings.
• Printing & paper: rubber ink rollers, paper press rolls.
• Hydropower & cement: wear-resistant liners, waterproofing layers.
