Scénarios d'application
- Leather shoes, casual shoes, sports sneakers safety shoe outsoles, midsoles & insoles
- Pouring process: Inject PU material into open or semi-closed molds for dense / microcellular sole blanks
- Spraying process: Evenly coat PU buffer layer on shoe uppers and mold inner surfaces
Avantages principaux
1. Flexible Production & Fast Mold Change
The simplified low-pressure mixing head enables quick color switching within minutes, supporting gradient, two-tone and multi-density soles. Equipped with servo metering & dual-density control system, one machine meets all footwear types including running shoes, outdoor boots and casual footwear. Ordinary metal or resin molds are acceptable to cut your sample development cost greatly.
2. Zero-Bubble Sole Structure
Adopts tank vacuum degassing + laminar flow feeding design to exhaust air inside molds orderly. High-precision synchronous metering and uniform mixing eliminate pinholes, internal voids and uneven texture, delivering pure, compact cross-section for finished soles.
3. Wear-Resistant & Anti-Fatigue Soles
PU material delivers 3–5 times higher abrasion resistance than ordinary rubber. The finished soles feature outstanding flex resistance, resisting cracking under repeated bending for sports and safety footwear heavy-duty usage.
4. Intelligent PLC Touch Control
One-click formula storage without professional technicians required. Self-cleaning mixing head prevents raw material curing blockage and reduces daily maintenance workload. All production formulas comply with international environmental standards for export orders.
5. Lower Investment & Operating Cost
The machine costs far less than high-pressure foaming equipment. Small mold bearing pressure extends mold service life. Precision gear pumps avoid splashing and raw material overflow waste; low running power cuts long-term electricity expenditure.
6. High Automatic Matching
Perfectly matched with annular shoe production lines, auto mold clamping stations and robotic pouring arms to minimize manual labor and boost daily output capacity.
