Polyurethane Products Manufacturer & Bulk Exporter to Germany
Heavy load-bearing hot-cast polyurethane rollers, heavy duty wheels, pipeline cleaning pigs, and railway suspension buffers.
45,000 sq.ft customs-bonded facility equipped with 50T–500T vacuum moulding presses, in-house mixing mills, and Class 5/7 cleanrooms.
Precision Polymer Engineering for Critical Industrial Operations
Cast polyurethane elastomers bridge the performance gap between synthetic rubber and engineering plastics, offering elastic flexibility alongside load-bearing capacities comparable to structural nylon. Horiaki processes premium MDI and TDI prepolymers cured with high-purity diamine (MOCA/ethacure) and diol chain extenders, formulating hardness grades from soft Shore 55A up to rigid Shore 75D.
In heavy abrasive slurry and mineral processing environments, Horiaki cast polyurethane components demonstrate extraordinary wear resistance. Standardized abrasion testing per DIN 53516 demonstrates volume loss under 15 mm³—providing 4x to 6x longer wear life than hardened carbon steel and ultra-high molecular weight polyethylene (UHMW-PE).
Our specialized casting line manufactures high-capacity industrial forklift wheels, heavy conveyor belt primary/secondary scrapers, vibrating screen modular panels, hydrocyclone liners, railway bogie suspension buffer pads, and pipeline cleaning pigs (polly pigs). With in-house precision steel hub machining and degreasing, our polyurethane-to-metal chemical bond prevents tread separation under heavy dynamic rolling resistance.

Chemical, Oil & Hydrolytic Stability
Polyether prepolymer formulations engineered for continuous submerged operation in water, sewage, hydraulic oils, and petroleum grease.
High Mechanical Rebound Resilience (> 60%)
Low internal hysteresis and low heat buildup under high-speed rotational cycles, preventing thermal blowouts in industrial drive wheels.
Precision Metal Core Chemical Bonding
Specialized primer and hot-bonding protocol ensures cohesive failure inside the polyurethane rather than hub debonding.

Frequently Asked Questions
Common questions regarding compound formulations, tooling lead times, and export logistics.
Why should we choose cast polyurethane over rubber or nylon for wheels and rollers?
Cast polyurethane provides 3x to 5x higher load-bearing capacity than rubber without permanent flat-spotting, while offering superior traction, acoustic damping, and non-marking floor protection compared to steel or hard nylon.
Can Horiaki strip and re-coat worn polyurethane forklift and conveyor wheels?
Yes. For overseas buyers and OEM service centers, we can receive metal cores, strip the residual elastomer, grit-blast, re-prime, and re-cast new high-grade polyurethane treads back to OEM specifications.
How does Horiaki test abrasion resistance on polyurethane compounds?
We test every batch on our DIN 53516 abrasion tester using standardized abrasive paper under 10N contact pressure. Our high-performance mining compounds consistently achieve volume loss under 15 mm³.
What is the largest polyurethane component Horiaki can cast?
Our automated meter-mix dispensing equipment can pour continuous single-shot casting weights up to 150 kg, accommodating large pipeline pigs, heavy flotation cell impellers, and large-diameter drive rollers.
What are the export shipping options from Chennai Port?
