A pressing machine purpose-built for leather seam opening — automatic seam opening, steam-free pressing that prevents deformation and discoloration, and operator onboarding measured in minutes.

Leather is the material that punishes a pressing station hardest. Steam carries moisture into the hide, and leather responds to moisture and heat together by deforming, shrinking and shifting colour — damage that cannot be pressed back out afterwards. The XST-235-7H1 is built around that constraint. It is an independently developed garment seam pressing machine that uses no steam at all, replacing manual pressing in the leather seam opening process with an automated, temperature-controlled operation.

Its working function is narrow and specific: opening and pressing flat the seam allowance on leather panels, so leather fabric seam opening reaches a consistent, production-grade standard. Seam opening runs automatically, and the pressing stroke is continuous rather than stop-start, at an adjustable speed up to 100 mm/s across a 5-20 mm pressing width. Because heat is applied by contact instead of carried in vapour, the hide never passes through a high-humidity stage — which is the mechanism behind the deformation and discoloration results.

Under the machine: dual servo motors rated 100 W + 100 W drive feed and pressing motion, overall power consumption is 280 W, working pressure is 0.6-0.7 MPa, and the unit runs on AC 220 V ±10%, 50/60 Hz. The manufacturer states an operator onboarding time of roughly three minutes.

Three subsystems replace the conventional steam chain:

• Intelligent temperature control — heat is delivered by contact and held at the set value, instead of being carried into the material by water vapour.
• Mechanical transport — dual servo motors carry seam opening and pressing through in one continuous pass, so feed is set by the machine rather than by hand.
• Steam elimination — the hide never enters a high-humidity condition, which is the mechanism behind the deformation and discoloration results.

The XST-235-7H1 is developed for the seam opening step in leather garment manufacture — leather outerwear and leather jackets among them — where the seam allowance has to be opened and pressed flat as part of building the panel.

Because the stroke runs continuously, the machine suits seam opening in continuous production rather than one-off finishing work.

• Purpose-built for leather seam opening: Designed specifically for opening and flattening seam allowance on leather with automatic operation.
• No steam infrastructure: Eliminates boiler, steam generation, and associated running costs from the station.
• Dual servo drive with continuous stroke: Two 100 W motors carry seam opening and pressing through in one pass at adjustable speed up to 100 mm/s.
• Industry-first development: Positioned as the first steam-free pressing machine in garment seam pressing equipment.

Being clear about where a machine stops is part of specifying it correctly:

• Pressing width is bounded: The 5-20 mm working band suits seam opening and edge work; not a wide-area pressing surface.
• Compressed air required: Supply at 0.6-0.7 MPa must be available at the station.
• Single-phase 220 V supply: Installations on other supply configurations need verification.
• Temperature is material-dependent: Settings must be matched to the specific leather or fabric in production.
• Focused function: Specifically for leather seam opening and pressing, not general-purpose garment finishing.
