A new medical twisting machine has been launched, assisting in the domestic production of special medical yarns.

The medical twisting machine, specifically designed for medical special fibers, has completed the entire machine testing and is now available on the market. This equipment is targeted at medical consumables enterprises and is used for the precise twisting processing of high-end yarns such as medical sutures, absorbable fibers, and medical woven substrates, filling the equipment gap in the medical fiber production process and promoting the quality upgrade and domestic substitution of medical thread materials.

Medical yarns have extremely strict standards for cleanliness, uniformity of twist, and stability of tension. Ordinary textile twisting machines are prone to problems such as tension fluctuations, yarn fuzz, and dust residue, making them unable to meet the production specifications of medical-grade products. This medical twisting machine adopts a clean machine body design, with dust-proof and sealed transmission components, reducing foreign matter contamination during the production process; it is equipped with a high-precision independent tension control system and servo drive module, with high precision in twisting adjustment, constant tension throughout the process, effectively reducing defects such as broken yarns and uneven thickness, and ensuring the stability of the mechanical properties of the finished yarns.

The equipment is compatible with various medical high-molecular raw materials such as absorbable polylactic acid (PLA), PGA, polypropylene (PP), and polyester (PET), and the produced yarns can be used for surgical sutures, medical woven catheter substrates, hemostatic dressing fibers, and medical woven nets, etc. The entire machine adopts a low-wear structure, minimizing fiber damage during the twisting process and meeting the pre-production requirements related to the biocompatibility of medical products. The equipment supports multi-sized and small-batch flexible production, allowing for quick switching of product models and adapting to the multi-category R&D and order demands of medical consumables enterprises.

The operation interface of the equipment is simple and intuitive, with all process parameters stored and retrievable, facilitating production traceability and meeting the traceability requirements of GMP production management in the medical industry; at the same time, noise reduction and energy consumption optimization designs have been implemented, with a compact machine body, making it easy to place in a clean workshop. The equipment has been verified through long-term continuous trial production, running stably, and can be put into production with a single machine, or can be combined with drawing, twisting, and winding equipment to form a complete production line.

The R&D director stated that with the rapid development of the domestic medical consumables industry, the market demand for high-end medical thread materials continues to grow. Precision twisting is the core process of sewing lines and other product production. The implementation of this medical twisting machine can help domestic manufacturers reduce the cost of importing equipment and improve the controllability of product quality. Currently, many medical consumables manufacturing enterprises have conducted sample tests, and the products are also expanding into the overseas medical consumables equipment market.
