Spare Parts of Twin Screw Extruder Machine

Product Description





Why Choose Nanjing Haisi ?

Q1: What makes your twin-screw extruders different from others?

A: We’ve been exclusively focused on twin-screw extruders since 2008. Unlike many manufacturers, we produce all core components in-house—screws, barrels, and liners are not outsourced. This ensures precision, reliability, and long-term availability for your machines.

Q2: What if I need replacement parts years after purchase?

A: We store detailed customer data for every machine we sell. If your screw or barrel wears out, even years later, you don’t need to provide measurements or photos. We can send you a ready-to-install replacement that fits perfectly—saving time, money, and risk.

Q3: How often do twin-screw extruder parts need replacement?

A: While a twin-screw extruder machine can last 10–15 years, screws and barrels are consumable components that may need replacement every 1–2 years, depending on materials and usage. By choosing a supplier like us who controls core part production, you ensure consistent performance and lower lifecycle costs.

Q4: My material wears out screws quickly. Do I have to replace the entire screw every time?

A: Not at all. Many of our screws are modular (segmental) design—multiple screw segments (sleeves) mounted on a single core shaft. For materials like fiber-filled PVC or abrasive compounds, only the worn segments need replacement, not the entire screw.


This design means:

  • Lower replacement cost – only change the parts that wear

  • Maintain original screw performance – the overall configuration stays intact

  • Protect your “screw combination” – your specific screw arrangement is your core process secret, which usually is not shared outside your company


Choosing the original manufacturer ensures:

You get exactly matching replacement segments

No need for guesswork or trial-and-error with generic parts
