Production line and factory setup overview
A small rubber-compounding and compression-moulding line producing one non-safety footwear outsole family from a qualified recycled-rubber/virgin-rubber blend through crumb and polymer release, recipe weighing, internal or two-roll mixing, sheet-off and batch cooling, preform cutting and weighing, multi-station heated sole compression moulding, controlled vulcanization, demoulding, flash trimming, conditioning and hardness, abrasion, flex, tear, adhesion, slip and ageing tests.
Recommended lowest-entry line configuration Launch one casual-shoe outsole pattern in one size family using a supplier-qualified compound containing a controlled recycled fraction. Contract a small kneader or two-roll mill with dust/fume control, sheet-off/cooling, preform cutter, one six-station heated compression press, aluminium or steel mould set and sole laboratory. Safety footwear, direct-injection soles and unknown tire powder are separate routes.
Production process and implementation sequence
- Compound ingredients release
- Recipe weighing and mixing
- Sheet-off, cooling and maturation
- Preform cutting and weighing
- Heated multi-station compression moulding
- Controlled vulcanization and demould
- Flash trimming and conditioning
- Sole and shoe-assembly tests
Products, capacity and market fit
- Local shoe workshops can buy consistent soles instead of importing every style.
- A controlled recycled fraction can reduce material cost for casual footwear.
- One pattern and size family controls mould capital and compound development.
- Flex cracking, abrasion, slip and upper adhesion determine real footwear performance.
- Recycled-content casual-shoe outsole - Pattern, size family, mass, hardness, density, abrasion, flex, tear, slip, adhesion and ageing - Local casual footwear assemblers
