Blesson Launches Premium Soft PVC Dental Tube Production Line – Raising the Bar for Medical Extrusion Equipment

Guangdong Blesson Precision Machinery Co., Ltd. is a professional manufacturer of plastic extrusion equipment, specializing in high-end soft PVC medical tube machine and medical pipe machine solutions. With years of profound industry experience, cutting-edge technology, and innovative capabilities, our flagship soft PVC dental tube production line ranks among the most advanced equipment on the market, delivering top-tier production solutions for the global medical consumables industry.

A dental suction tube is a core auxiliary consumable in dental procedures, featuring a composite structure of a soft PVC tube with a built-in metal wire. As a leading medical pipe machine manufacturer, we understand that key quality criteria for such tubes include medical-grade raw material compliance (odorless, safe for oral contact), uniform wall thickness, superior flexibility and airtightness, precise metal wire positioning (shape retention after bending), and zero bubbles or defects. Our soft PVC dental tube production line is engineered to meet and exceed these stringent standards.

As the starting point of this high-end production line, the raw material selection and preprocessing stage fully demonstrates the professionalism of our soft PVC medical tube machine design. We carefully select medical-grade soft PVC resin and high-toughness low-carbon steel wire, combined with seven core components to form a comprehensive production system, ensuring quality control from the source. The entire equipment housing is constructed from SUS304 stainless steel, fully complying with medical-grade hygiene requirements. Equipped with Siemens PLC control systems, ABB frequency converters, and high-quality electronic components from ABB and Schneider, this medical pipe machine provides a solid core guarantee for precise and stable operation. Details of each core component are as follows:

1. Metal Wire Unwinding Device: Maintains constant and uniform unwinding tension, effectively preventing stretching deformation or jamming of the metal wire. This ensures the metal wire is fed into the mold with precise stability, laying a solid foundation for subsequent composite molding.

2. Metal Wire Preheating Device: Features a precision temperature control design that rapidly and evenly heats the metal wire, enhancing its adhesion to the soft PVC material. This prevents delamination or detachment in the finished product, ensuring the stability of the composite structure.

3. Single-Screw Extruder: Tailor-made for medical-grade soft PVC, the extruder is equipped with a specially designed screw with unique flight geometry, enabling higher plasticizing efficiency and more uniform melting while maximizing the retention of the raw material’s flexibility and biocompatibility. Integrated with Siemens PLC control systems and ABB frequency converters, it achieves micron-level regulation of parameters such as screw speed and temperature. Combined with the stable performance of electronic components from ABB and Schneider, it ensures a continuous and smooth extrusion process, fully meeting the stringent precision requirements for medical consumables production.

4. Extrusion Mold: Manufactured using high-precision machining technology with a scientifically designed flow channel. It ensures the uniform extrusion of soft PVC melts, controlling the tube wall thickness tolerance within an extremely narrow range and guaranteeing consistent molding results.

5. Vacuum and Cooling Tank: Incorporates a multi-stage vacuum adsorption and cooling system that rapidly sets the tube dimensions. It avoids deformation or diameter reduction caused by uneven cooling, ensuring the roundness and dimensional accuracy of the tube.

6. Haul Off Machine: Utilizes variable frequency speed control to maintain stable traction speed, precisely matching the extrusion speed. This prevents tube stretching or accumulation, ensuring uniform length and wall thickness of the finished product.

7. Flying Knife Cutting Machine: Equipped with a high-speed rotating cutting blade and a precision positioning system, it delivers clean, burr-free cuts with minimal length deviation. It can flexibly adapt to cutting requirements for products of different specifications.

8. Receiving Device: Features an automatic winding design with adjustable tension, enabling neat storage of finished tubes. It prevents wear or deformation during transportation, improving the efficiency of the post-production process.

Blesson’s soft PVC dental tube production line – a flagship soft PVC medical tube machine – relies on strict raw material control, high-end core configurations, and sophisticated component technology to empower customers to stably produce the most high-end dental suction tubes available on the market.
