Product Overview
Specially developed for mass production of labor protection safety footwear. Realizes one-step casting and molding of PU midsole & outsole for anti-impact, anti-penetration safety shoes.
This low-pressure PU foaming equipment is specially developed for the mass production of labor protection safety footwear. It realizes one-step casting and molding of PU midsole and outsole for anti-impact and anti-penetration safety shoes. The system features a high-degree of automatic operation, requiring only 2–3 operators for the full production cycle. An optional automatic robotic manipulator is available for unmanned feeding and pouring, with all running speeds adjustable for flexible production. Ultra-precise raw material dosing control within ±0.3% ensures consistent hardness, abrasion resistance, and impact resistance of finished safety shoe soles batch by batch. The low-pressure energy-saving running design reduces abrasion on core wearing parts, bringing easy daily maintenance and extended service life. The professional dual-density integrated molding function serves as the core configuration for safety shoe production, stabilizing finished product quality for large-volume orders. The machine matches our solvent-free and water-blown PU formula system, supporting low-VOC closed-loop production to meet international environmental emission standards. The system also supports molding of daily PU footwear accessories including sandals, slippers, and beach shoe soles as secondary compatible applications. Finished shoe protective performance shall be verified via third-party authoritative labs.
Operation Workflow
Raw Material Preparation
Prepare PU raw materials according to the target mix ratio (A:B = 100:35~85). Select the appropriate formulation for safety shoe sole requirements (hardness, abrasion resistance, impact resistance).
Tank Loading & System Setup
Load materials into the 200L tank system. Configure the PLC control system with the required parameters for the specific safety shoe model. Optional robotic manipulator can be set up for automated feeding and pouring.
Ultra-Precise Dosing & Low-Pressure Mixing
The PLC-controlled dosing system (accuracy ≤±0.3%) dispenses materials precisely. The mixing head speed is adjustable within 4,000–18,000 r/min for optimal blending. The dosing rate is adjustable within 30–150 g/s for different shoe sole sizes.
Dual-Density Casting & Molding
The mixed PU material is cast into safety shoe molds for one-step molding of midsole and outsole. The professional dual-density integrated molding function is the core configuration for safety shoe production, ensuring stable quality for large-volume orders.
