Technical FAQ
What advantages do PU soles have over rubber soles?
PU soles are 30-40% lighter than rubber, with better resilience and more comfortable wearing. The production process uses liquid raw materials for foam molding, simpler than rubber's mixing and calendering process, requiring smaller equipment investment. Additionally, PU soles are fully recyclable, making them more environmentally friendly.
How to choose sole molds?
Sole molds typically use aluminum alloy materials for long life and fast heat conduction. Mold design must match your sole structure and size requirements. We have partnered professional sole mold suppliers for recommendations. For first-time cooperation, we suggest clients provide sole samples or drawings for mold solution development.
How to change colors during production?
Color changes mainly involve cleaning mixing heads and pipelines. High-pressure machines have self-cleaning mixing heads, requiring 1-2 cleaning agent flushes. Color change time controlled within 30 minutes. For multiple colors, consider increasing tank quantities or preparing pre-mixed materials in various colors.
Can antibacterial and odor-resistant insoles be made?
Yes. Antibacterial insoles require special polyurethane compound materials (containing antibacterial agents). Our equipment's high metering precision accurately adds antibacterial components. Materials provided by professional compound suppliers, we can recommend qualified suppliers.
What material requirements for soles exported to Europe?
European footwear material environmental requirements mainly include: no azo dyes, no heavy metals, phthalate limits, etc. Polyurethane compound suppliers can provide REACH and OEKO-TEX standard material certifications. We cooperate with material suppliers for complete supply.
