Office Chair Double-Needle Sewing Machine

The term 'office chair double-needle' typically refers to a double-needle sewing machine used for sewing leather or thick materials on office chairs. Its core function is to enhance sewing efficiency and aesthetics. Below are common models and key purchasing considerations:

I. Mainstream Models and Functional Characteristics

1. Aoling RN-4420 Series

   • Basic Model: The RN-4420 is an industrial triple-synchronization thick-material double-needle sewing machine that employs computer direct drive and integrated feeding technology. It can sew thick materials such as car seat cushions, seat belts, and tents, priced at approximately 9,550 yuan.
   • Custom Model: For example, the RN-4420D is equipped with automatic thread trimming and pneumatic presser foot lifting functions, specifically designed for office chairs or car seats, priced at around 18,600 yuan, suitable for mass production needs.

2. Other Brand Double-Needle Sewing Machines

   • Manyi Brand MY-8720: A fully automatic computerized flat-seam sewing machine that supports sewing thick materials such as clothing and tents, priced at 6,800 yuan per unit, offering excellent cost-effectiveness.
   • Triple-Synchronization Double-Needle Sewing Machine 6620: Priced at 6,000 yuan per set, it focuses on leather processing and is suitable for small workshops or custom studios.

II. Price Ranges and Purchasing Recommendations

• Economy Type (6,000-8,000 yuan): Such as the Manyi Brand MY-8720, suitable for users with limited budgets and simple sewing needs, but it is necessary to confirm whether it supports thick materials like leather.
• Professional Type (9,550-18,600 yuan): The Aoling RN-4420 series offers comprehensive functions, suitable for high-demand scenarios such as office chairs and car seats. Custom models can further enhance efficiency.
• High-End Type (Above 18,600 yuan): Some brands offer fully automated solutions (such as automatic thread trimming and pneumatic presser foot lifting), suitable for large-scale production lines.

Notes for Purchasing:

• Confirm whether the merchant supports customization services (e.g., Guangzhou Aoling Sewing Machine Co., Ltd. offers customization for some models).
• Delivery locations are mainly concentrated in Guangzhou and Dongguan, Guangdong, with a typical supply cycle of within 3 days. It is necessary to plan the production cycle in advance.

III. Application Scenarios and Adaptability

The double-needle sewing machine forms parallel stitches through simultaneous double-thread sewing, enhancing sewing strength and aesthetics. It is particularly suitable for:

• Leather Office Chairs: Such as genuine or faux leather materials that require high-strength stitches to prevent cracking.
• Thick Material Splicing: Such as the connection between the chair back and seat cushion, which requires penetrating multiple layers of material.
• Mass Production: Automated functions (such as automatic thread trimming) can reduce manual operations and improve efficiency.

For specific model quotations or technical parameters, it is recommended to contact the merchant directly (e.g., Ms. Chen at 139 2505 0273) for the latest information.
