Application Scenarios
This low-pressure foaming equipment is specially matched with KPU automatic production lines, widely used for manufacturing the following footwear products:
1.Sports shoe KPU uppers, shoe toe caps and side decorative parts
2.KPU shoe labels, brand trademarks and shoe surface patches
3.Soft rubber ornaments, faux leather shoe fabrics and other small precision PU components
It supports low-pressure pouring and molding, which is very suitable for small and medium batch production of various KPU footwear accessories.
Core Advantages
Stable Metering System, Effectively Reduce Product Defect Rate
Equipped with dual high-precision metering pumps, the material ratio can be controlled within ±1% deviation. Stable raw material proportion avoids common defects such as bubbles, uneven foaming and product deformation in KPU products, greatly improving the finished product yield and reducing your raw material waste cost.
High-Speed Mixing Head, Ensure Stable Product Physical Performance
The high-speed mixing head runs up to 8000 r/min, enabling full collision and uniform mixing of two-component raw materials. Consistent foaming effect guarantees stable hardness, elasticity and dimensional accuracy of each batch of KPU shoe materials, fully meeting the quality requirements of large-scale continuous orders.
Intelligent PLC Control, Convenient Connection With KPU Assembly Line
The whole machine adopts integrated PLC + touch screen intelligent control system, with reserved communication interface to realize seamless data connection with your KPU production line. You can realize unified production parameter monitoring and automatic operation management, greatly improving the overall workshop production efficiency.
Automatic Solvent Cleaning Function, Lower Maintenance Cost
Built-in automatic cleaning system can quickly flush the mixing pipeline and mixing head after each batch of production. It avoids raw material curing blockage, reduces manual disassembly cleaning work, saves solvent consumables, and effectively extends the service life of core equipment components.
Warranty & After-Sales Service
1.1-year warranty for the whole machine core electrical and hydraulic components
2.Overseas engineer on-site installation, commissioning and operator operation training
3.Lifetime remote online technical guidance and KPU formula debugging support
4.Timely supply of original spare parts to avoid production shutdown losses
