KINGMAX Launches GC20618 Full Range Long Arm Compound Feed Sewing Machines

KINGMAX, a professional manufacturer of heavy-duty industrial sewing machines, is pleased to announce the expansion of its GC20618 long arm compound feed sewing machine lineup, with multiple new variants added to this proven product range for global manufacturers. Built on our well-received GC20618 platform, this updated series offers a wider selection of working arm lengths, needle configurations and direct-drive options, to meet diversified heavy-sewing production demands across industries.

The GC20618 series adopts proven triple compound feed (needle, walking foot and bottom feed) mechanism. It ensures synchronized material feeding, effectively preventing material shifting, puckering and uneven stitch when sewing multi-layer thick leather, foam composite, canvas and tarpaulin. The machine supports a maximum stitch length up to 10 mm and high presser foot lift up to 16 mm, making it easy to handle bulky stacked workpieces. Equipped with a large vertical rotary hook and large bobbin, it reduces bobbin replacement frequency and delivers stable, consistent stitches, even under continuous heavy-load operation. The built-in automatic lubrication system extends service life and cuts maintenance downtime.

To fit different workpiece sizes and production workflows, the GC20618 product matrix offers flexible configurations:

• Arm lengths: 14", 18", 25", 40", 45" long arm options.
• Needle types: Single needle, 2-needle, 3&4-needle models.
• Power options: Standard clutch motor and energy-saving direct-drive servo motor versions.
• Longer arm models create extra working space for large-size workpieces. This is especially helpful for upholstery, automotive interior, outdoor tent & tarpaulin, luggage and leather goods factories.
• Direct-drive variants save power, lower noise and support optional automatic thread trimming, ideal for automated workshop upgrading.

The GC20618 series is engineered for these main application sectors:

• Furniture upholstery: sofas, mattresses, cushion foam
• Automotive industry: car seat covers, interior panels, insulation materials
• Outdoor products: heavy tents, PVC tarpaulins, protective covers
• Leather & luggage: thick leather bags, travel cases, lifting straps
• Industrial textiles: flame-retardant composite fabrics and protective equipment

"Many of our customers need flexible long-arm heavy sewing machines to upgrade their production lines," said the KINGMAX product team. "Instead of offering only one fixed model, we developed the full GC20618 range. Factories can select the correct arm length and needle setup according to their product dimensions, without overspending on unnecessary capacity."

All GC20618 series machines undergo strict factory testing before shipment. KINGMAX provides full technical documentation, spare parts support and after-sales service for worldwide distributors and end manufacturers.
