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 a wide range of medium and light‑duty vehicles. The polyurethane microcellular solid structure completely eliminates air leakage and blowout issues inherent to pneumatic tires. Featuring excellent aging and abrasion resistance, the tires enjoy long service life, cutting maintenance frequency and full‑lifecycle costs. Equipped with self‑developed servo‑driven gear metering pumps and high‑shear mixing heads, the machine delivers metering accuracy of ±0.5% and maintains material mixing uniformity above 98%, ensuring uniform cell structure and complete chemical reaction. The intelligent production control system dynamically adjusts foaming temperature in real time with precision within ±1℃, maintaining stable foaming ratio and material hardness across batches. The composite production mode combining single‑cavity and multi‑mold linkage drastically boosts productivity. Line changeover is shortened to within 1.5 hours, enabling flexible response to multi‑variety orders. Adopting environment‑friendly water foaming technology, the machine complies with RoHS & REACH standards and controls raw material loss at 5%–7%, achieving green manufacturing and higher profit margins.
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.
