When running a footwear production line, upper quality at the lasting stage directly determines your final product's fit, finish, and rejection rate. The TH-516B Shoe Upper Softening Wrinkle Removal Machine — an industrial steam-based unit designed for upper pre-treatment — addresses one of the most persistent pain points in shoe manufacturing: inconsistent upper softening and wrinkle formation before lasting.
B2B buyers evaluate equipment not just on specifications but on how those specifications translate to measurable production outcomes. Here's how the TH-516B Shoe Upper Softening Wrinkle Removal Machine bridges that gap for footwear manufacturing decision-makers.
The TH-516B is a professional-grade shoe upper softening wrinkle removal machine purpose-built for footwear factories. It applies a combination of high-temperature steam and dry heat to shoe uppers — including the toe vamp area — achieving thorough softening that reduces material resistance before lasting. This dual-mode heating approach ensures upper fibers are fully memory-reset, minimizing wrinkle formation and shape relapse during subsequent assembly steps.
Also known in production environments as a vamp softening humidifier steam machine, the TH-516B fits naturally into lasting lines where consistent upper conditioning is a prerequisite for quality output. The machine's control panel — with a power switch, indicator light, water shortage alarm, and steam regulation dial — gives operators direct, at-a-glance control over all primary functions during a production shift.
| Parameter | Value |
|---|---|
| Voltage | 380V (three-phase) |
| Rated Power | 9 KW |
| Machine Dimensions (L × W × H) | 87 × 45 × 130 cm |
| Machine Weight | 50 KG |
| Optional Power Configurations | 4 KW / 6 KW |
Note for procurement teams: the TH-516B Shoe Upper Softening Wrinkle Removal Machine operates on 380V three-phase power supply. Confirm electrical infrastructure before installation. The 87 × 45 × 130 cm footprint fits within standard lasting area layouts, and at 50 KG the machine can be repositioned without heavy lifting equipment.
The TH-516B applies both steam and dry heat simultaneously. This dual approach conditions the upper material throughout. The steam regulation control lets operators calibrate for leather, PU, or fabric mesh. Higher steam pressure does not always mean better results — exceeding the optimal threshold on thin synthetics causes surface bubbling and delamination rather than firmer conditioning.
Water can be refilled without interrupting steam output. The water shortage alarm provides advance warning before the machine runs dry, preventing unplanned downtime mid-shift.
Rapid conditioning cycles support consistent throughput. The downstream cost of poorly conditioned uppers — rework, inspection time, compounding rejection rates — is reduced by thorough pre-lasting treatment.
At 9 KW rated power, the TH-516B generates steam without a central boiler. The 4 KW and 6 KW optional configurations suit lower-volume production environments.
Four controls — power switch, indicator light, water shortage alarm, steam regulation — support quick operator onboarding and consistent settings across rotating operators.
The TH-516B shoe upper softening wrinkle removal machine conditions uppers before lasting, increasing pliability and reducing stress wrinkles at the toe vamp. The steam regulation control allows parameter adjustment to match upper material characteristics and reduce post-cooling shape regression.
Removes surface wrinkles from already-formed uppers without re-lasting. Useful in quality remediation on formal and dress shoe lines where surface finish standards are precise.
Panel-adjustable steam regulation allows recalibration between leather and synthetic uppers without tool changes, supporting OEM factories switching between multiple customer specifications.
