This customized plastic modification compounding line is a one-stop turnkey solution specially designed for plastic modification and high-fill compounding scenarios, focusing on solving the core needs of stable production, high efficiency and uniform product quality for manufacturers. Taking the co-rotating parallel twin-screw extruder (JCD series) as the core, the whole line adopts a modular design concept, which can be fully customized according to your specific production requirements—including material formula (glass fiber reinforced, mineral filled, flame retardant, alloy modification), expected output, workshop layout and automation level.

Equipped with self-produced high-quality bimetallic screw & barrel as core components, matched with high-torque transmission system, multi-stage vacuum exhaust and intelligent control system, the line realizes seamless connection from raw material feeding, mixing, extrusion, plasticizing to pelletizing, cooling and packaging. It effectively avoids problems such as uneven mixing, material degradation, low pellet purity and unstable output in traditional modification production, and is widely used in engineering plastic modification, general plastic reinforcement and functional compounding, helping you reduce production costs and improve product competitiveness.

All core components are self-produced and strictly tested, ensuring compatibility and stability of the whole line, with optional specifications to match different production needs:

1. Co-rotating Parallel Twin-Screw Extruder (Model: JCD 52C–135C, Diameter: 51.4mm–133mm optional), equipped with high-rigidity tri-axle transmission gearbox, forced lubrication and cooling system, supporting high-torque continuous operation.
2. Bimetallic Wear-Resistant Screw & Barrel: Base material 38CrMoAlA, alloy hardness HRC 50–65, alloy layer depth 0.8–2.0mm, optional nitriding treatment (HV 850–1000), strong wear resistance and corrosion resistance, suitable for long-term processing of abrasive materials.
3. Automatic Feeding & Dosing System: Optional single-screw, twin-screw or side feeding unit, with precise dosing function, supporting powder, granule, bulk material and liquid additive feeding, ensuring uniform raw material mixing.
4. Multi-Stage Vacuum Exhaust System: 1–2 sets of vacuum exhaust ports, effectively removing moisture, volatile substances and impurities in raw materials, improving the purity and appearance of modified pellets.
5. Pelletizing Unit: Optional water-cooled strand pelletizing, air-cooled die-face pelletizing or water-ring pelletizing, matching different material characteristics, ensuring uniform pellet size and smooth surface.
6. PLC Intelligent Control System: Touch screen operation, real-time monitoring of temperature, speed, output and other parameters, supporting stepless speed regulation, easy to operate and maintain, reducing labor costs.
7. Auxiliary Equipment: Cooling conveyor, automatic screening machine, material storage silo and packaging unit (optional), realizing full-process automation of production.

This customized line is highly adaptable to various plastic materials and modification processes, mainly applicable to:
