1. The die head is made of alloy tool steel, with a hard-chrome‑plated flow channel; the coating thickness is 0.02–0.03 mm, and the surface roughness is Ra 0.05 µm, ensuring excellent corrosion resistance. 2. The barrel and screw are machined to high precision, offering superior wear and corrosion resistance. A dual‑mixing structure ensures uniform blending and outstanding plasticization performance. 3. A hardened‑gear helical‑bevel gearbox with direct‑drive transmission. 4. Temperature control employs PID regulation, providing rapid response and high accuracy. 5. The calender rolls feature a spiral‑groove water‑cooling system, with optimized coolant distribution for uniform roll surface temperatures. The roll surfaces are hard‑chrome plated and mirror‑polished, achieving a surface roughness of Ra 0.05 µm and a coating hardness of HV ≥ 850.

2. The barrel and screw feature high mating precision, excellent wear resistance, and superior corrosion resistance; they employ a dual‑stage mixing structure for uniform compounding and outstanding plasticization performance.
3. Helical gear reducer with hardened teeth, directly coupled drive;
4. Temperature control employs PID regulation, offering rapid response and high precision.
5. The calender rolls feature a spiral‑type water‑channel design, ensuring uniform cooling‑water distribution and even surface temperature. The roll surfaces are hard‑chrome plated and mirror‑polished, with a surface roughness of Ra 0.05 µm and a coating hardness of HV ≥ 850.
6. Smooth winding, with constant-tension control via a magnetic powder clutch;
Suitable for producing plastic sheets such as polypropylene (PP), polyethylene (PE), and biodegradable plastics, it is used in thermoforming packaging products, stationery items, imitation corrosion‑resistant tapes, and more. Examples include packaging boxes, trays, cups, bowls, and plates.
