Flat Knitting Machine Needles

• Product Overview
• Flat knitting machine needles are precision components used in V-bed flat knitting machines to produce shaped knitwear, collars, cuffs, and full-fashion garments. Unlike circular knitting needles, flat knitting needles operate on a straight or V-shaped needle bed, enabling the creation of complex stitch patterns, including cables, fair isle, intarsia, and jacquard.
• Our flat knitting needles are manufactured from high-grade alloy steel with advanced vacuum heat treatment, delivering optimal hardness (60–64 HRC) and exceptional toughness. Available in a wide gauge range from 1.5G to 18G, our needles accommodate various yarn types—from coarse woollen yarns to fine cotton and synthetic blends. Precision-ground butt, hook, and latch geometries ensure smooth carriage movement, consistent stitch formation, and reduced machine vibration.
• Compatible with all major flat knitting machine brands including Stoll, Shima Seiki, Protti, Cixing, Steiger, Universal, and Jumberca, brother , silver reed and all Chinese brand flat knitting machine.  
• Our needles are ideal for producing sweaters, scarves, hosiery, and technical textiles. Customised specifications and surface coatings (e.g., chrome plating, nitriding) are available upon request.

          1. Technical Highlights

• Optimised Butt Geometry – Precision-ground butts ensure smooth interaction with the carriage cams, reducing wear and extending both needle and machine life.
• Advanced Heat Treatment – Vacuum hardening and tempering deliver superior hardness (≥ 60 HRC) with excellent toughness to withstand high-speed reciprocating motion.
• Mirror-Finish Polishing – Our advanced polishing system delivers a mirror-like finish on the needle shank, while ensuring that the latch remains completely undamaged throughout the process – reducing friction, yarn abrasion, and latch bounce.
• Dimensional Precision – Manufactured to tight tolerances (±0.01mm) for perfect compatibility with needle beds, sinkers, and cams.
• Latch Design Optimisation – Available with standard latches or high-speed lightweight latches to suit different knitting speeds and yarn types.

          4. Selection Guide

• To assist customers in selecting the right flat knitting needle for their      specific application

• Consideration         Recommendation
• Machine Brand & Model: Provide your machine type and model for precise matching
• Gauge: Lower gauge (1.5G–10G) for coarse/chunky yarns; higher gauge (12G–18G) for fine/fingering yarns
• Needle Type: Standard latch needles for basic knitting; transfer needles for shaping/cables;
• Yarn Type & Count: Coarse/spun yarns → larger hooks; fine/smooth yarns → finer hooks
• Fabric Structure: Plain jersey, rib, cables, intarsia, jacquard, full-fashion shaping
• Knitting Speed: Standard latches for normal speeds; lightweight latches for high-speed operation

          5. How Flat Knitting Needles Work – Operating Principle

• Flat knitting needles operate on a reciprocating carriage system with two needle beds (front and rear) arranged in an inverted V shape:
• Yarn Feeding – The carriage traverses across the needle beds, feeding yarn to the needles through a yarn carrier.
• Knitting Action – As the carriage moves, the cams guide the needle butts, causing the needles to move forward and backward.
• Loop Formation – The needle hook catches the new yarn while the latch opens to release the old loop, forming a new stitch.
• Stitch Transfer (Optional) – On transfer needles, a movable transfer spring opens to receive a loop from the opposite bed, enabling shaping and complex patterns.
• Stitch Knock-Off – The old loop is pushed off the needle hook, completing the stitch.
• This mechanism enables the production of fully shaped garments directly on the machine, minimising post-knitting cutting and sewing.
