E-TPU Foamed Sole Molding Machine

Specially Designed for TPU Foamed Sole Production
This machine is specially developed for the molding of foamed shoe soles using TPU materials.
It is an ideal solution for manufacturers seeking stable performance and reliable quality in TPU sole production.

Crank-Type Clamping Structure
The machine adopts a crank-type mold clamping structure, providing strong clamping force and more even force distribution across the platen.
This helps improve molding stability and ensures consistent product quality.

High-Precision Platen System
The machine is equipped with high-precision platens, including fixed and movable mold platens.
With encoder control, the positioning accuracy is kept within ±0.1 mm, while the mold frame pressure can reach up to 6 kg, ensuring precise and stable molding performance.

Flexible Mold Compatibility
Thanks to its independent platen design and servo-adjustable mold gap, the machine can support the shared use of molds for different products.
This improves production flexibility and helps reduce tooling costs.

Pressure-Holding Material Tank Design
The machine uses a pressure-holding material tank design, combined with pulse control, proportional control, and pressurized feeding methods.
This helps ensure defect-free products while preventing material blockage in the injection gun.

Dual Steam Control System
The steam system adopts a dual-control design with a balance valve and an analog proportional valve.
This allows steam heating fluctuation to be controlled within ±0.1 kg, helping maintain stable processing conditions and improve product consistency.

Fast and Stable Mold Opening and Closing
The machine uses both high-pressure and low-pressure pumps to achieve fast as well as ultra-slow mold opening and closing movements.
This allows material particles to distribute more evenly, resulting in more stable product quality.

Automatic Production with Siemens Controller
The machine is equipped with a human-machine interface and a Siemens control system, enabling fully automatic operation with minimal manual intervention.
This helps improve production efficiency, reduce labor dependence, and support unmanned manufacturing.
