Thermoplastic Polyurethane (TPU) is highly sensitive to temperature fluctuations, which can drastically alter its viscosity and final physical properties. The closed-loop PID (Proportional-Integral-Derivative) system continuously monitors and adjusts the barrel temperature in real-time. This ensures a perfectly homogeneous melt, preventing thermal degradation and guaranteeing that the final sole exhibits uniform flexibility, structural integrity, and maximum abrasion resistance.
A clamping force of 75KN ensures that the heavy metal mould halves are held together with immense, unyielding pressure during the critical injection phase. This completely prevents the high-pressure polymer melt from escaping the mould cavity—a common defect known as flashing. As a result, the manufactured soles require virtually zero post-production trimming, saving significant labor costs and ensuring a flawless, clean edge on every single shoe.
Absolutely. The machine is engineered to accommodate standard mould frame sizes of 200*400mm and 200*430mm with ease. Furthermore, the intuitive microcomputer interface allows operators to quickly save, store, and recall specific injection profiles (such as pressure, volume, and cooling time) for different moulds. This drastically reduces mechanical downtime during style or size changeovers, maintaining high daily throughput.
Our advanced proportional hydraulic system is specifically designed for longevity and low maintenance. Routine upkeep primarily involves monitoring the hydraulic fluid levels, ensuring the fluid remains uncontaminated by factory debris, and replacing the hydraulic filters at recommended intervals. Because the system only draws power proportionally to the required action, it generates far less heat and experiences significantly less internal wear compared to traditional, full-throttle hydraulic setups.
The high-resolution stroke measuring system tracks the exact physical position of the injection screw down to the fraction of a millimeter. This extreme mechanical precision ensures that the exact required volume of PU (20-60g/s) or TPU (50cm³/s) is injected into the mould every single time. By completely eliminating over-packing and under-filling, you utilize exactly the amount of raw material required, significantly reducing expensive polymer waste over the course of a production year.
