- Pneumatic Sole Pressing Machine: Uses compressed air to apply pressure.
Stitchdown Machine
Stitchdown machines stitch the sole directly to the upper. This creates a durable and waterproof bond.
Table: Comparison of Sole Attaching Machines
| Machine Type | Bonding Method | Application | Strength | Speed |
|---|---|---|---|---|
| Cementing Machine | Adhesive | Applying adhesive to sole and upper | Medium | Medium |
| Sole Pressing Machine | Pressure | Bonding sole and upper with pressure | High | Medium |
| Stitchdown Machine | Stitching | Stitching sole directly to the upper | Very High | Low |
Shoe Molding Machines
Shoe molding machines shape and form different parts of the shoe. These machines are essential for creating specific shoe styles.
Injection Molding Machine
Injection molding machines inject molten material into a mold. This creates the sole or other plastic parts.
- Single Injection Molding Machine: Creates one part at a time.
- Multi-Injection Molding Machine: Creates multiple parts simultaneously.
Compression Molding Machine
Compression molding machines press material into a mold. This is used to create rubber soles or other molded components.
Heat Setting Machine
Heat setting machines apply heat and pressure to shape the shoe upper. This creates a lasting shape and improves the shoe’s fit.
