JUKI AMS-221F-GS3020/SZ5000 — Computer-Controlled Digital Pattern Sewing System for Heavy to Extra Heavy-Weight Materials (300 × 200 mm Sewing Area) The JUKI AMS-221F-GS3020/SZ5000 is a computer-controlled digital cycle sewing system designed for heavy to extra heavy-weight materials. With a large 300 × 200 mm sewing area, monolithic feeding frame, and advanced digital sewing technology, this model delivers high productivity, excellent seam accuracy, and stable performance for demanding industrial sewing applications. The machine is suitable for free pattern stitching, parts sewing, reinforcement stitching, special bartacking, label attaching, emblem sewing, Velcro attachment, and other programmable sewing operations. What Sets the JUKI AMS-221F-GS3020/SZ5000 Apart? The AMS-221F-GS3020/SZ5000 combines a large sewing area, high-speed operation, precise digital control, and heavy-material sewing capability in one production-ready platform. As a result, the machine provides: 300 × 200 mm sewing area Designed for heavy to extra heavy-weight materials Digital sewing system Monolithic feeding frame PK 3-pedal unit (PK47) Maximum sewing speed of 2,800 sti/min Main-shaft direct-drive system Encoder-controlled X-Y feed Semi-dry head technology Programmable intermediate presser Active thread tension control How Does This Machine Improve Your Production Workflow? Shorter Cycle Time The machine reaches its maximum sewing speed of 2,800 sti/min by the second stitch and maintains high speed until just before the end of sewing. This significantly reduces total cycle time. Fast and Stable Thread Trimming JUKI’s stepping-motor-controlled thread trimming mechanism provides quick and consistent trimming performance, helping reduce idle time between sewing cycles. Direct-Drive Responsiveness The main-shaft direct-drive system improves machine response, reduces vibration, and supports precise start/stop performance during programmed sewing. High Sewing Speed Across Stitch Lengths The AMS-221F supports high-speed sewing even at larger stitch pitches. Sewing speed is automatically controlled according to stitch length, helping maintain seam quality and productivity. Reduced Power Consumption The direct-drive system and encoder-controlled X-Y drive reduce power consumption by approximately 45% compared with the conventional AMS-221E, making the machine more economical for continuous production. Improved Seam Accuracy The encoder-controlled X-Y stepping motor checks feed position during sewing, reducing pattern deformation that can occur when sewing heavy materials at high speed. Semi-Dry Head Technology The needle bar and thread take-up units are grease-lubricated, while the hook receives only a minute quantity of oil. This helps protect products from oil stains. Programmable Intermediate Presser The lower dead point of the intermediate presser can be changed during sewing to support multi-layered materials. This helps prevent skipped stitches, thread breakage, and marks on the product. Monolithic Feeding Frame The monolithic feeding frame securely holds the material during sewing, ensuring stable positioning and consistent pattern accuracy. Double-Stepped Feeding Frame Stroke The feeding frame can be lowered in two steps, allowing fine material positioning before sewing starts. Active Thread Tension Needle thread tension can be changed stitch by stitch according to material thickness and sewing direction. This reduces setup time and ensures reproducible stitch quality. IP-420 Touch Panel The IP-420 color LCD touch panel allows easy pattern editing, sewing data management, and machine setup. It supports 14 display languages and includes key-lock customization and simplified operation mode. Large Memory Storage The machine can store up to 999 patterns and 500,000 stitches in the machine body. Data can be transferred using USB, CompactFlash, SD cards, and other supported media.
