PU Insole Production Line — Ground-Rail Circular System

A compact polyurethane insole production system with mold carriers mounted on a fixed circular ring frame. The ring structure keeps molds in a continuous loop, moving past injection, curing, and demolding stations in sequence. Designed for manufacturers who need reliable daily output of 800–2000 pairs with minimal floor space.

Who it’s for

• Insole suppliers producing 800–1500 pairs per shift
• Shoe factories with limited floor space requiring compact equipment layout
• Manufacturers running 3–5 SKU changes per day
• Orthopedic footbed producers needing consistent density control

How it works

Mold carriers are fixed to the circular ring frame and driven by a motor through the ring path. Each carrier holds one or two molds and stops at stations for loading, injection, curing, and unloading. The ring structure is self-contained — no ground rails, no long straight runs. The high-pressure foaming machine injects at one position; molds then move through the curing zone before returning to the unloading station.
