CAPSTAN's extruders have been very popular recently and have been recognized by many cable factories.
What questions of building wire and cable extrusion line?
When a customer requests a building wire cable extrusion line, they typically focus on production efficiency, product quality,
cost-effectiveness, and compliance with industry standards. Below are the key questions they may ask,
along with recommended responses to address their concerns professionally.
What is the maximum production speed (m/min) for building wires?
The FAQ section lets you show expandable content. Enter questions and answers, or more detailed information for anything you want!Our extrusion line supports speeds up to 600 m/min (depending on insulation material).
Adjustable capstans and tension control ensure smooth processing for 1.5mm² to 35mm² conductors.
Equipped with dual-layer extrusion for simultaneous insulation and sheath application (if required).
Can this line process both PVC and XLPE insulation? How do you prevent material degradation or bubbles?
PVC & XLPE compatible – Adjustable temperature zones (120-220°C) and screw design (L/D ratio 25:1) ensure proper melting.
Pre-drying system (optional) removes moisture to prevent bubbles.
Automatic gauge control (AGC) ensures uniform thickness (±0.02mm).
How much power does this line consume? Are there energy-saving features?
Energy-efficient DC/AC motor drive reduces power consumption by 20-30% vs. traditional models.
Heat recovery system (optional) recycles waste heat for preheating.
Servo-controlled extruders minimize material waste (<1% scrap rate).
Does this line meet international standards (IEC, UL, BS, VDE)? Can it print markings compliant with regulations?
Fully compliant with IEC 60227, UL 83, BS 6004, VDE-0281.
Laser/inkjet printer for permanent markings (size, voltage, manufacturer ID).
Flame-retardant & low-smoke options available for safety-critical applications.
What kind of technical support do you provide? Is there a warranty?
24/7 remote support via video call for troubleshooting.
On-site installation & training (optional).
2-year warranty on critical components (screw, barrel, motor).
What’s the total cost, and how long is the delivery time?
Delivery: 3 months (depending on order volume and customization).
- High-speed extrusion (up to 600 m/min) for mass production.
- Multi-material compatibility (PVC, XLPE, LSZH).
- Energy-saving & low waste for cost efficiency.
- Full compliance with international standards.
- Easy operation & quick changeover for flexible production.
