Keywords: SJ-80X25, 80mm high speed extruder, double-layer co-extrusion machine, photovoltaic wire extruder, LSHF extruder, secondary insulation extruder, co-extrusion unit

Product Description: The SJ-80X25 is the secondary high-speed extruder of the SJ-90+80/25 double-layer photovoltaic wire co-extrusion unit. Working alongside the SJ-90X25, it forms the second insulation layer in a single-pass dual-layer co-extrusion process. Equipped with a permanent magnet motor for ~30% energy savings and a 27:1 BM screw with mixing head, it ensures uniform plasticization and stable high-speed production of photovoltaic wire and low smoke halogen-free cable.

Specifications:

• Model: SJ-80X25
• Screw L/D Ratio: 27:1 (BM screw with mixing head)
• Configuration: Part of SJ-90+80/25 double-layer unit
• Motor: Permanent magnet motor (energy saving ~30%)
• Crosshead: U20q free-adjustment crosshead
• Application: Photovoltaic wire, LSHF / XLPE LSHF insulation & sheath

Key Features:

1. Secondary Co-Extrusion Extruder – Forms the second layer in the dual-layer insulation process together with the SJ-90X25.
2. Permanent Magnet Motor – Energy consumption reduced by nearly 30% with improved linkage effect.
3. 27:1 BM Screw with Mixing Head – Good plasticization and high extrusion capacity; easy-to-remove blossom-shaped handle.
4. U20q Free-Adjustment Crosshead – Precise dual-layer forming and easy adjustment.
5. Constant Screw Temperature – Air cooling and outlet-line cooling ensure stable extrusion.

FAQ:

1. What is the role of the SJ-80X25 in the co-extrusion unit? It is the secondary extruder that forms the second insulation layer in the SJ-90+80/25 dual-layer co-extrusion process.

2. What motor does the SJ-80X25 use? It uses a permanent magnet motor that reduces energy consumption by nearly 30%, directly connected to the reducer for improved linkage effect.

3. What screw does the SJ-80X25 use? It uses a 27:1 aspect ratio BM screw with a mixing head for good plasticization and high extrusion capacity.

4. What crosshead does the SJ-80X25 use? It uses the U20q free-adjustment crosshead, working together with the U14 high-quality double-layer co-extrusion extruder head for precise dual-layer forming.
