Pu Pouring Machine (Pu Conveyor)

The PU Conveyor Type Footwear Sole Molding Machine is a fully automatic, high-performance production system specially designed for modern footwear manufacturing. It is ideal for mass production of PU soles with consistent quality, excellent finish, and high output efficiency. This machine is widely used in the manufacturing of sports shoes, casual shoes, sandals, slippers, and safety footwear.

The machine operates on a continuous conveyor-based workflow, where molds move smoothly through different stages of the production cycle. This includes PU material injection, controlled heating and curing, cooling, and demolding. The conveyor system ensures uninterrupted production, reduces manual handling, and maintains uniform cycle times for every mold, significantly improving productivity.

At the core of the system is a high-precision PU metering and mixing unit. It accurately measures and mixes polyol, isocyanate, and additives in the correct ratios, ensuring stable chemical reactions and consistent material properties. The PU material is injected into the molds with precise control over volume, pressure, and temperature, resulting in footwear soles with uniform density, excellent elasticity, and strong bonding characteristics.

The machine is equipped with a temperature-controlled curing tunnel, which provides evenly distributed heat as the molds travel through it. This ensures proper curing of PU material, minimizing defects such as bubbles, shrinkage, or uneven surfaces. The result is durable, lightweight, and flexible soles that meet international footwear quality standards.

A PLC-based control panel with user-friendly interface allows operators to easily adjust and monitor key parameters such as injection quantity, conveyor speed, curing temperature, and production cycle time. This advanced automation reduces labor dependency, improves repeatability, and enables quick changeovers for different sole designs and sizes.

Constructed with a heavy-duty steel frame and high-quality industrial components, the machine offers excellent stability, long service life, and low maintenance requirements. Integrated safety features, including emergency stop buttons, protective guards, and fault detection systems, ensure safe and reliable operation in a footwear production environment.

Overall, the PU Conveyor Type Footwear Sole Molding Machine is a perfect solution for footwear manufacturers looking to achieve high production capacity, consistent sole quality, reduced material waste, and cost-effective automated manufacturing, making it an essential asset for competitive footwear production lines.
