The Role of Welding Machines in the Medical Industry

Equipped with advanced plastic welding technologies, welding machines play an indispensable role in the manufacturing of critical products in the medical industry. Through precise and stable welding processes, they provide core guarantees for the quality, safety, and compliance of various medical devices. These machines are widely used in the production and processing of a variety of medical products, meeting the rigorous requirements of medical scenarios.

I. Core Manufacturing for Adapting to Multiple Types of Medical Products

1.Medical Instrument Handles: For thermoplastic medical instrument handles featuring lightweight and ergonomic designs, welding machines can achieve precise welding. The welded handles are compatible with imaging/X-ray examinations, offering greater operational flexibility than metal handles and facilitating healthcare professionals' work during diagnosis and treatment. Common materials include PC, ABS, and PSU, with typical joint designs such as Tongue & Groove Round Energy Director and Step Round Energy Director.

2.Robotic Surgical End-Effectors: As key components for robot-assisted surgery, these devices include various tools such as graspers, scissors, and dissectors. Welding machines ensure excellent dexterity and controllability through stable welding processes, contributing to safer and more efficient surgeries. Suitable materials cover PC, PEI, PEEK, PSU, and PA, with common joint designs including Round Energy Director (Servo) and Staking Post Configurations.

3.Intravenous Cannulas: Serving as core consumables for drug delivery and fluid drainage, intravenous cannulas require tight welding of their components by welding machines to meet the diverse size needs of different patients. Mainly made of PC, PP, and Nylon, they adopt joint designs like Tongue & Groove Round Energy Director.

 

II. Ensuring High Quality and Safety of Medical Products

1.Precise Control of Welding Quality: Welding machines guarantee welding results through optimized parameters. For instance, the sensing speed is stably set at 1 mm/s, and the welding speed is controlled between 0.25 - 1.5 mm/s. Meanwhile, leveraging Melt-Match technology, the Melt-Match percentage is adjusted to 2% - 7% (2% - 5% for some products) based on different products, ensuring tight and firm welds and avoiding risks such as leakage during product use.

2.Compliance with Strict Molding Specifications: Welding machines meet the special molding requirements of medical plastics. Only compatible materials with a melting temperature difference within 30°F and a melt flow index difference within 10% are selected for welding. The use of regrind is minimized; if necessary, its proportion shall not exceed 25%. Additionally, mold release agents are prohibited to prevent material components from affecting the safety of medical products.

3.Adherence to Industry Compliance Standards: The welding process and finished products can meet the FDA 21 CFR Part 11 safety standards. Advanced cycle/graph data collection and production analysis functions enable full traceability of the entire welding process, providing data support for the quality control of medical products.
