Dual Density PU Sole Manufacturing Process – A Detailed Technical Guide
Dual Density Polyurethane (PU/PU) sole manufacturing is one of the most advanced moulded shoe construction technologies used in modern footwear production. This process allows manufacturers to combine two different material characteristics into a single sole unit, delivering both comfort and durability without compromising performance. In a typical dual density construction, the outer layer (outsole) is engineered with high-density polyurethane to withstand abrasion and harsh working environments. At the same time, the inner layer (midsole) is produced using low-density foamed PU, which provides cushioning, flexibility, and shock absorption. Because of this…
