Seam sealing machine from China

A seam sealing machine bonds tape over a stitched seam with hot air, and the seam stays waterproof only when heat, roller pressure and speed suit your tape and fabric, which a demo on the supplier's fabric does not show.

Two quotes, one machine name

What hides inside the price

Heat source

Twenty-five of thirty listings were hot air. Ask the maximum air temperature, how stable it holds, and heater element life.

Rollers

Ask roller width and material, top and bottom drive, and whether rollers change for each tape width.

Speed and tape feed

A foot pedal sets speed. Ask whether tape feed and cutter follow it automatically.

Arm shape

A cylinder arm reaches round sleeves. A post arm suits shoes, gloves and other three-dimensional items.

Control panel

Ask whether temperature, speed and pressure can be stored as settings per fabric.
