Product Overview
This machine is mainly used for mass production of air‑free polyurethane solid tires for commuter bicycles (including shared bikes), mountain bikes, children's bikes, wheelchairs, golf carts, electric scooters and other medium & light‑duty vehicles.
This PU foam machine is purpose-built for the mass production of air-free polyurethane solid tires for commuter bikes (including shared bikes), mountain bikes, children's bikes, wheelchairs, golf carts, and electric scooters. The microcellular solid structure completely eliminates air leakage and blowout risks, with excellent aging and abrasion resistance for long service life and lower full-lifecycle costs. Self-developed servo-driven gear metering pumps and high-shear mixing heads deliver ±0.3% accuracy and mixing uniformity above 98%, ensuring uniform cell structure and complete reaction. Intelligent temperature control adjusts foaming temperature within ±1℃ to maintain stable ratio and hardness across batches. The composite single-cavity plus multi-mold linkage mode boosts productivity, with line changeover shortened to within 1.5 hours. Water foaming technology complies with RoHS & REACH standards and controls raw material loss at 5%–7%.
Operation Workflow
Raw Material Preparation & Formula Selection
Prepare polyurethane raw materials (A:B = 100:90–120). Select the appropriate formula for the target tire size (12–29 inches) and tread pattern via the PLC touch screen.
Tank Loading & Temperature Setting
Load materials into the 200 L tanks. The intelligent temperature control system dynamically adjusts foaming temperature with precision within ±1℃ to maintain stable foaming ratio and material hardness.
High‑Precision Mixing & Pouring
The servo‑driven gear metering pumps and high‑shear mixing head operate at 4,000–5,000 r/min with metering accuracy ±0.3%. Material mixing uniformity remains above 98% for uniform cell structure and complete reaction.
Multi‑Mold Molding & Curing
The composite production mode combines single‑cavity and multi‑mold linkage to drastically boost productivity. Tires range from 12 to 29 inches with various tread patterns. Line changeover is shortened to within 1.5 hours.
