Extruder screws made of black oxide film (blackened threaded blocks)

Materials commonly used by Nanjing Sikerun:

38CrMoala — высокое соотношение цены и качества, высокая степень износостойкости и коррозионной стойкости. Эксклюзивная обработка шнеков экструдера Sikerun обеспечивает длительный срок службы как шнека, так и экструдера.

W6Mo5Cr4V2 — высококачественный материал, высокая твёрдость. Эксклюзивная обработка Sikerun обеспечивает высокую общую твёрдость шнека экструдера, продлевая его срок службы.

Powder alloy extruder screws. Custom-made according to customer requirements, delivery time is up to 50 days.

Product Features:

1. Increase in wear resistance by 30-50% (hardness of HV400-600 oxide film);

2. Greatly improve rust and corrosion resistance (oxide film isolates air/moisture);

3. Slightly rough surface, improving the efficiency of material transportation (reduce slippage).

Areas of application:

1. Processing of abrasive materials (e.g., fiberglass, mineral fillers, recycled materials);

2. Production lines for long-term continuous production (e.g., pipe and profile extrusion);

3. Equipment stored in a humid environment or outdoors;

4. Processing of high-viscosity materials, requiring high transportation efficiency.
