Manufacturing Excellence

 

Solamni’s outsole manufacturing process combines traditional craftsmanship with modern automation technology:

  • Compression Molding: Utilized for high-performance rubber outsoles, ensuring uniform density and exceptional abrasion resistance.
  • Injection Molding: Applied to TPU outsoles to achieve high-efficiency production and facilitate complex structural designs—particularly suitable for soccer cleats and athletic shoe support components.
  • Secondary Vulcanization: Eliminates internal material stresses, preventing outsole deformation during long-term storage or use.
  • Automated Buffing: Every outsole undergoes automated buffing prior to leaving the factory, significantly enhancing adhesion during subsequent processing at the shoe manufacturing plant.

 

 

Professional OEM & ODM Customization
  • Custom Logo Branding: Precise molding of the brand logo on the outsole—specifically at the arch or heel area.
  • Functional Additives: Incorporation of special functional properties, such as anti-static (ESD), flame retardancy, or fragrance.
  • Texture Development: Design of specific traction patterns (e.g., herringbone, micro-studs, suction-cup grips) tailored to meet specific anti-slip rating requirements.
  • Color Matching: Strict adherence to Pantone color codes for precise color matching; customization options include transparent and glow-in-the-dark outsoles.

FAQ

Q1: What is the benefit of using TPU instead of Rubber for an outsole? A: TPU (Thermoplastic Polyurethane) is significantly more abrasion-resistant and can be made transparent. It is also lighter and provides better structural support for high-performance athletic shoes like football cleats.

Q2: How do you ensure the outsole won't peel off from the shoe upper? A: We treat our outsoles with a specialized primer or mechanical buffing process at the factory. We also provide technical data on the best adhesive types (PU glue or water-based glue) to use with our specific materials.

Q3: Can Solamni produce outsoles that pass the ASTM or SATRA slip-resistance standards? A: Yes, our heavy-duty rubber series is specifically engineered to meet and exceed SRC slip-resistance standards, making them ideal for work safety and hospitality footwear.

Q4: What is your typical lead time for custom mold development? A: For a new outsole design, 3D prototyping takes about 3-5 days, and the final steel mold production takes approximately 20-30 days depending on the complexity.

Q5: Do you offer eco-friendly or biodegradable outsole options? A: We offer Bio-based TPU and outsoles made with 20%-50% recycled rubber content. We are also developing biodegradable TPU solutions to meet the latest ESG requirements.

Q6: How do you control the "Blooming" (white powder) issue on rubber outsoles? A: We use high-quality anti-oxidants and optimized vulcanization agents in our compounding process to ensure that our rubber outsoles remain clean and pitch-black even after 12-24 months of storage.
