As a critical component for computerised flat knitting machines, this jack is engineered to adapt to 5G, 7G, 9G, 12G, 14G, and 16G needle gauges—covering the most common needle spacing needs in the textile industry. It ensures stable needle control during the production of diverse fabrics (wool, cotton, chemical fibers), directly influencing the smoothness and consistency of knitted products, from thick sweaters to thin t-shirts.

Produced by Yantai Xinyang Electronics Co., Ltd.—a trusted supplier of textile machinery parts—the jack is manufactured under strict quality control protocols. This ensures it meets the high demands of automated knitting lines, whether for small workshops or large-scale textile factories.
The jack series includes multiple models tailored to different knitting machine requirements:
• 7G3.5.2 Middle Plate (01/02 variants)
• 12G6.2 Middle Plate 01
• HP6.2 Middle Plate
• HP7.2 Middle Plate 01
• 14G7.2 Middle Plate 02
All models are fully compatible with 5G to 16G computerised flat knitting machines, eliminating the need for model-specific replacements.
• Packaging Options: 50 PCS for 7G3.5.2, 12G6.2, and HP6.2 models; 100 PCS for 14G7.2 and HP7.2 models. Bulk customization (e.g., 200 PCS packs) is available for large orders.
• Material: High-strength carbon steel with a hardness rating of HRC 45-50, ensuring wear resistance and long-term durability under continuous operation.
• Dimensional tolerance: ±0.01mm, guaranteeing accurate needle alignment to avoid fabric defects.
• Service life: Up to 8,000 hours of continuous use in standard textile mill conditions.
Supports 5G to 16G needle gauges, allowing manufacturers to switch between fabric types (e.g., 5G woolen scarves, 16G cotton undershirts) without replacing jacks—reducing equipment costs and downtime.
High-strength carbon steel resists deformation and wear, even in 24/7 production environments. This durability cuts maintenance frequency, lowering operational costs for textile businesses.
The ±0.01mm dimensional tolerance ensures uniform needle movement, minimizing common defects like dropped stitches or uneven patterns. This is critical for meeting quality standards of mid-to-high-end knitwear brands.
For factories producing 10,000+ knitted garments monthly, the 50/100 PCS packaging meets bulk replacement needs. This minimizes downtime for part changes, ensuring production lines run efficiently and meet tight delivery deadlines.
Smaller operations with diverse order requirements (e.g., custom sweaters, promotional knitwear) benefit from the jack’s multi-gauge compatibility. It eliminates the need to invest in multiple jack types, making it a cost-effective solution for businesses with limited budgets.
Luxury knitwear brands rely on the jack’s strict precision to produce smooth, high-quality fabrics. The ±0.01mm tolerance ensures intricate patterns (e.g., cable knits, lace details) are reproduced accurately, maintaining brand reputation for excellence.
A dedicated team provides 24/7 support in English and Chinese, assisting with gauge selection, installation guidance, and troubleshooting. This ensures global clients receive timely help, regardless of time zone.
All jacks come with a 1-year warranty against manufacturing defects. If parts fail to meet performance standards within the warranty period, free replacements are provided—no additional costs for clients.
Yantai Xinyang offers tailored solutions, including custom packaging (e.g., branded packs for OEM clients) and material upgrades (e.g., stainless steel for humid coastal factories). This flexibility meets unique client needs across different regions and production environments.
