Product Overview
This machine is used to manufacture medium & low hardness polyurethane elastomer products, including medical solid tires, wheelchair wheels, roller skate wheels, skateboard wheels, luggage casters and other small load-bearing rollers.
This PU foam machine is purpose-built for manufacturing medical solid tires, wheelchair wheels, and other small load-bearing rollers. The tires deliver stable shock absorption to absorb vibration during pushing. The dense, smooth surface resists repeated wiping with alcohol and disinfectant, repels dust, and enables easy cleaning, fully meeting sterile standards for hospital environments. Optimized material composition reduces rolling resistance for effortless pushing, with rolling noise controlled below 55 dB. The intelligent pouring system realizes full automation from raw material pretreatment, mixing, precision pouring to automatic sorting, eliminating manual quality fluctuations and ensuring uniform hardness, rebound, and dimensions. Flexible production with product changeover ≤1 hour, versus 2–3 days for traditional processes. Optional integrated inspection covers hardness, shock absorption, noise, and surface cleanliness, stabilizing mass production yield above 98%.
Operation Workflow
Raw Material Preparation & Color Paste Selection
Prepare polyurethane raw materials (A:B = 100:90–120). Color paste can be added inside the mixing unit to satisfy personalized appearance and functional requirements of different customers.
Tank Loading & Parameter Setting
Load materials into the 200 L tanks. The self‑developed intelligent pouring system dynamically adjusts pouring temperature and raw material ratios for optimal process conditions.
Intelligent Mixing & Precision Pouring
The mixing head operates at 4,000–5,000 r/min with metering accuracy ±0.3%. Discharge flow rate is 100–500 g/s. The intelligent control system ensures consistent mixing and pouring quality.
Molding, Curing & Automatic Sorting
The injected material cures in the mold to form solid tires. Full automation from pouring to automatic sorting ensures efficient production. Product changeover takes ≤1 hour for rapid response to multi‑category orders.
