In the manufacturing of screw barrel for extrusion of blow molding, ensuring the wear and corrosion resistance of the inner wall is crucial. It directly affects both equipment service life and product quality.

At Intai, we select high-quality alloy steels as the base material. These steels feature excellent mechanical strength and corrosion resistance, capable of withstanding high temperature, high pressure, and aggressive raw materials. By partnering with leading material suppliers worldwide, we guarantee all raw materials meet strict international standards.

We also adopt advanced surface treatment technologies to strengthen the barrel’s inner wall. The nitriding process creates a dense and hard protective layer, which greatly improves hardness and resistance to wear and corrosion. This treatment helps the barrel withstand contact with abrasive plastics as well as chemical media such as acids and alkalis. Además, Intai is actively developing and applying bimetallic coatings and ceramic coatings to further enhance long-term durability.

Finally, design optimization is equally important. With precise structural design, advanced CNC manufacturing, y estricto control de calidad, our screw barrels maintain stable performance, minimizing risks of premature wear or corrosion caused by design flaws or machining errors.

By combining material selection, surface treatment, and optimized design, Intai ensures that screw barrels for blow molding extrusion achieve superior wear resistance, larga vida útil, and stable production performance.
