FAQ

What should I check when buying a used automatic sewing machine?

Inspect stitch quality, head alignment, servo motor condition, PLC/software version, wiring, and wear on cams/bearings. Ask for maintenance records, test run time, and evidence of parts replacement.

What electrical and installation requirements should I know?

Confirm voltage, phase and amperage requirements, earthing, and space for ventilation. Many industrial machines need 3-phase power and a stable floor or mounting table.

How should an automatic sewing machine be shipped safely?

Ship on a pallet or crate with the head immobilized, secure loose parts, drain fluids if applicable, and insure transit. Use carriers experienced with machine tool transport for proper lifting and rigging.

How easy is it to get spare parts and consumables?

Availability depends on brand and age. Popular brands have global networks; for older or niche models verify sources for needles, bobbins, motors, and electronic modules before purchase.

What routine maintenance keeps machines reliable?

Regular cleaning, lubrication per manual, timing checks, tension calibration, and periodic inspection of belts, bearings and electronic connections. Keep software backed up and update firmware as recommended.
