1. Extruder: The extruder is a single-screw plastic extruder; the specific model is selected based on the product size. All models are equipped with hardened‑gearbox reducers, ensuring robustness and durability. The screw and barrel are made from 38CrMoAIA nitrided steel, with a hardness exceeding HV900. The screw design is well‑proven, delivering excellent plasticization and stable output. Temperature control is managed by a PID controller, while variable‑frequency drives are used to save energy and enable precise adjustment of the screw speed. 2. Profile Extrusion Die: The die consists of two main components—the extrusion die head and the sizing die. The extrusion die head is crafted from S136H mirror‑finish steel, featuring smooth flow channels that prevent material buildup at corners. The sizing die is polished to a mirror finish, ensuring superior surface quality of the final product.

2. Profile extrusion die: Composed of an extrusion die head and a sizing die, it is manufactured using S136H mirror‑finish steel for the extrusion die. The die’s flow channels are smooth, with no sharp corners or material buildup, while the sizing die is polished to a mirror finish, ensuring a smooth product surface with minimal draw marks.
3. Three-dimensional electric setting table with a three‑axis adjustable frame, offering electric fore/aft, lateral, and vertical adjustments for convenient operation. Equipped with a vacuum pump and a water pump, it provides 12 vacuum ports and 12 cooling‑water connections, accommodating most types of setting molds and ensuring high versatility. The entire machine features a compact, robust design, minimal vibration, and a sleek, aesthetically pleasing appearance.
4. Crawler Tractor: The crawler tractor consists of three main components: a power unit, a material-clamping device, and the tractor’s traveling track. An AC motor drives the main shaft gear via a reduction gearbox; the main shaft gear engages with the chain mounted on the track, enabling reciprocating linear motion.
5. Cutting Saw/Feeding Rack: The cutting saw employs a reciprocating blade‑cutting mechanism with an alloy saw blade, driven by a dedicated motor and equipped with a blade collet. It delivers stable, vibration‑free operation, low noise, and smooth cut edges. An automated reciprocating platform ensures precise in‑line positioning during cutting, while an integrated material‑collection rack automates the entire cutting and collection process. High level of automation.
