INDUSTRIES SERVED: Automotive , Manufacturing & Automation, Electronics, Sports & Recreation

 

 

We specialize in manufacturing customized polyurethane rubber bumper (not foma). They are made of thermoset casting polyurethane , offering reliable protection and cushioning for various industrial applications. These PU bumpers are engineered to absorb shocks and vibrations, safeguarding equipment and cargo during transit and use.

Polyurethane bumpers serve automotive, industrial manufacturing, construction and distribution sectors. Key uses: shielding equipment from impact/wear, aligning automated components, and cushioning vehicle interiors.

Mounting TypeAdhesive-backed, bolt-on, or threaded insertsRetail display cases (adhesive-backed, no drilling); Industrial machinery (bolt-on, secure)
Special Polyurethane AdditivesAnti-microbial, fire-retardant, hydrolysis resistanceFood processing equipment (anti-microbial); Auto repair lifts (oil-resistant)

Application: Where Our Polyurethane bumper Are Used?

- Conveyor and material handling systems: Our heavy-duty & industrial bumpers shield machinery and production lines from collisions and impacts.

- Logistics: Protect forklifts and warehouse equipment to avoid damage during transportation.

- Shipping: Our PU impact bumpers and PU edge bumpers secure containers, support docking systems, and aid cargo securement.

- Automotive: Machine bumpers on vehicle assembly lines cushion and safeguard components.

- Construction and heavy-duty machinery: Vital for heavy machinery—preventing damage to both equipment and infrastructure.

Advantages of Urethane bumper

custom-polyurethane-bumpers

- Lower Maintenance Costs: Urethane bumpers outperform rubber counterparts with better abrasion/tear (5 times) and impact resistance. Longer lifespan improves process efficiency by reducing frequent part replacements.

- Weather and UV resistance: It won’t crack or harden when exposed to ozone/oxygen , suitable for outdoor application.

- Chemical Resistance: Our urethane bumpers resist more chemicals than most rubbers/plastics, suiting oil refineries, food/beverage plants, and paper/pulp facilities.

- Non-marking: Urethane bumpers are non-marking, bondable to metal/wood/plastics, and FDA-compliant .

- Lower Tooling Costs: Urethane has lower tooling costs than rubber/plastics, making it economical for prototypes and low-volume bumper production.

- Noise Dampening & Vibration Dampening: Urethane bumpers reduce noise, vibration, and movement transfer especially in heavy machinery. They creat safer, quieter workspaces . 

- Guiding and Alignment: Bumpers guide and align components in automated and manufacturing systems.

Why Choose Our Urethane bumper ?

- Techincal support.

Based on operating conditions, sizes and working load, we can design, mold, and test shock-absorbing solid polyurethane bumpers to develop stress/strain (compression/deflection) curves required for your specifications.

- Harsh industrial or outdoor environments. Our polyurethane bumpers excel in extreme conditions where standard options fail. They maintain structural integrity in high-humidity settings (e.g., marine docks) without mold or swelling, resist strong corrosion from chemicals in refineries, and perform steadily from -40°F (cold storage) to 220°F (foundries). Unlike regular bumpers that crack or degrade, ours stay reliable, avoiding sudden failures in harsh industrial or outdoor environments.

- Industry-Specific Formulations.

We have exsiting custom polyurethane formulas for specific working environmen. Food-grade bumpers meet FDA standards for processing lines (resisting sanitizers), anti-microbial for hospital and supermarket.

- Quality inspection for each urethane bumpers(hardness, dimension and defects)

- No or low tooling cost

- Polyurethane bumpers can be machined, molded, and cast to customer requirements.
