1. Pin‑type reinforcement kneading ensures more thorough plasticization of the rubber compound. The barrel pins shear, agitate, and mix the rubber compound, ensuring uniform blending and even heating while preventing localized scorching. This results in a dense inner structure of the rubber hose, reducing porosity and delamination, and enhancing its pressure resistance and aging‑resistance properties.

2. Cold-feed molding process, streamlining production steps. The rubber compound can be fed directly at room temperature, eliminating the need for preheating or baking, thereby removing the preliminary processing step, reducing the requirement for auxiliary equipment, simplifying material charging, and streamlining the production process.

3. High production capacity and stable output. The pin‑type structure enhances conveying performance, delivering superior material uptake and significantly boosting output compared with conventional cold‑feed extruders. It ensures stable discharge flow and uniform hose wall thickness, addressing the longstanding production challenges of low throughput and poor efficiency.

4. Multi-zone temperature control with a wide adjustable process range. Multi‑zone independent temperature control precisely regulates barrel and die temperatures, accommodating a wide range of rubber formulations to effectively prevent under‑cure and scorching, and is suitable for extruding rubber hoses made from various materials.

5. Screw barrel, wear-resistant and durable. The screw, pin, and barrel are subjected to hardening and wear‑resistant treatment, making them well suited for highly filled rubber compounds. This ensures slow wear during long‑term continuous operation, reduces the frequency of replacing wear parts, and extends the service life of the entire machine.

6. Modular, turnkey configuration with a high degree of automation. It can be equipped with dual‑belt traction, a cooling tank, eccentric cutting, and a servo‑driven cable‑winding reel, enabling integrated extrusion–cooling–traction–cutting–winding operations. Each unit features independent variable‑frequency speed control, ensuring straightforward speed matching and minimizing manual intervention.

7. Multi-purpose, with broad product compatibility. By simply changing the mold, the equipment can produce hydraulic hoses of various specifications, water and gas delivery hoses, construction‑machinery hoses, and automotive rubber tubing, while also accommodating hose production and the manufacture of certain rigid rubber profiles, resulting in high equipment utilization.

8. Easy to debug, with convenient maintenance and inspection. The machine features a well‑thought‑out structural layout, with convenient disassembly and cleaning for easy daily maintenance; when surface defects occur, fault diagnosis is straightforward, minimizing downtime.
