Cable Extrusion Screw
Single or twin screws for PE, PVC, XLPE, and rubber insulation extrusion. Custom L/D ratio available.
Extrusion Barrel
Bimetallic or nitrided barrel for cable insulation and jacketing extruders. Matched to screw diameter.
Cable Extrusion Die / Mold
Crosshead die sets for single and double insulation. Includes die, tip, and adjusting ring.
Heating Element & Band
Ceramic, mica, and cast aluminum heating bands for extruder barrel and crosshead temperature zones.
Haul-off Belt & Roller
Polyurethane or rubber haul-off belts and pressure rollers for caterpillar and wheel-type haul-offs.
Melt Pressure Sensor
High-temperature melt pressure transducers for extruder barrel and die head monitoring.
Melt Filter / Screen Pack
Stainless steel screen packs and breaker plates for continuous filtration of extruded insulation material.
Temperature Controller
PID temperature controllers and thermocouples for extruder barrel zone control.
Maintenance Guide
When Do Extrusion Parts Need Replacement?
Understanding the warning signs helps you plan maintenance before a breakdown stops your production line.
Screw & Barrel Wear
Gradual wear between screw flights and barrel bore reduces output efficiency and increases energy consumption.
- Output rate drops more than 10–15% without process changes
- Melt pressure fluctuates abnormally during steady-state operation
- Increased material degradation or color contamination
- Screw-barrel clearance exceeds 0.15mm on measurement
Die & Tooling Damage
Die bore scoring and tip wear cause uneven wall thickness, which leads to cable rejection and material waste.
- Wall thickness eccentricity exceeds specification tolerance
- Visible scoring or pitting on die bore surface
- Concentricity cannot be adjusted back to center
- Surface finish of insulation deteriorates
Heating System Failure
Failed heating elements cause temperature zone instability, leading to poor melt quality and potential material degradation.
- One or more temperature zones fail to reach setpoint
- Resistance reading of heating band is open or shorted
- Visible burn marks or discoloration on heating band surface
- Temperature controller shows sensor fault alarm
Haul-off System Wear
Worn haul-off belts cause inconsistent cable tension, which affects outer diameter stability and surface quality.
- Belt slippage even at maximum clamping pressure
- Surface cracking or delamination visible on belt
- Outer diameter variation increases beyond tolerance
- Uneven cable surface marks caused by belt irregularities

FAQ
Frequently Asked Questions
What information do I need to provide to get a spare parts quote?
Ideally: part name or description, machine brand and model, key dimensions or specifications, quantity required, and delivery country. If you don't know the part name, just send photos or drawings — our engineering team will identify the part for you.
Can you supply spare parts for non-HONGKAl cable machines?
Yes. We supply spare parts for most cable machine brands. Send us photos, drawings, or samples and we will confirm compatibility and produce the correct parts.
What is the typical lead time for spare parts?
Standard parts: 7–15 working days. Custom or precision parts (e.g. extrusion screws, dies): 15–30 working days depending on specifications. We will confirm exact lead time in the quotation.
Do you provide shipment photos before dispatch?
Yes. We send photos of packed parts before every shipment so you can confirm the parts are correct before we dispatch. This is standard procedure for all HONGKAI spare parts orders.
What is the minimum order quantity (MOQ) for spare parts?
MOQ varies by part type. For standard parts, MOQ is typically 1 piece. For custom-manufactured parts, MOQ may be 2–5 pieces depending on tooling requirements. We will confirm MOQ in your quotation.
How do I confirm the correct screw and barrel dimensions?
Please provide: screw outer diameter, barrel inner diameter, screw length (or L/D ratio), thread form, and material requirement. If you have the original drawings, please attach them. Alternatively, send photos of the worn parts with a ruler for scale.
