In footwear production, proper stiffener activation is critical for achieving accurate heel shaping, structural support, and long-lasting product performance. The PR 1139 Heater Box is specifically designed to preheat and soften stiffeners before they enter the counter moulding or seat lasting process.

The machine provides uniform heating across the working surface, ensuring that stiffeners reach the optimal temperature for moulding without overheating or damaging the material. This controlled softening process improves the effectiveness of downstream operations, resulting in better fit, shape retention, and overall footwear quality.

Suitable for a wide range of footwear manufacturing applications, the PR 1139 helps manufacturers achieve consistent production results while reducing material rejection and process variations.
