Pu Pouring Machine (Pu Banana)

This machine is a fully automatic PU (Polyurethane) shoe sole injection molding system, designed for high-volume, consistent, and precision footwear sole production. It integrates advanced mechanical, hydraulic, and electronic controls to ensure efficient and repeatable manufacturing.

The system features a rotary indexing table fitted with multiple mold stations, allowing simultaneous operations such as mold opening, closing, injection, curing, and demolding. This continuous rotation significantly increases output while minimizing idle time. Each mold station is engineered for accurate alignment and uniform pressure distribution, resulting in soles with excellent surface finish, dimensional accuracy, and structural strength.

At the core of the machine are high-precision PU dosing and mixing units. These units accurately meter polyol, isocyanate, and additives in exact proportions, ensuring stable chemical reactions and consistent material quality. The mixed PU is injected into closed molds under controlled pressure and temperature, producing soles with superior elasticity, durability, and bonding properties.

The machine is controlled via a centralized PLC-based control panel, which allows operators to easily set and monitor parameters such as injection volume, temperature, curing time, and rotation speed. This automation reduces human error, improves repeatability, and enables quick changeovers for different sole designs and sizes.

Built with a robust steel frame and industrial-grade components, the machine offers long operational life, low vibration, and high stability even during continuous production. Safety features such as emergency stop systems, protective guards, and fault alarms ensure safe operation for factory environments.

Overall, this PU shoe sole injection molding machine is ideal for manufacturing sports shoes, casual footwear, safety shoes, slippers, and sandals, delivering high productivity, reduced material waste, lower labor dependency, and consistent premium-quality soles suitable for modern footwear manufacturing demands.
