Small Laboratory Cast Film MachineDongguan JiuTong Machinery Co., Ltd. National Unified Service Hotline: 138-2574-4148   Shao Li. Address: Second Industrial Zone, Guchong Community, Wanjiang District, Dongguan City

Our company specializes in designing, processing, and supplying rubber and plastic equipment: engineering plastic testing laboratory equipment mixing instruments: commonly used two-roll open mill, internal mixer for high-filling formulations, flat plate hot press, single-screw extruder, twin-screw mixing and pelletizing machine, conical small twin-screw extruder, sheet extruder, 3D consumables extruder, PVC pipe extruder, PE blown film machine, etc.

Equipment features: The extruder has high production efficiency, low energy consumption, excellent plasticizing effect, and strong adaptability to raw materials. The extruder adopts specially designed screws and barrels. The screw design includes no shear section and mixing section, using a gradual structure. Different extruder units in the laboratory require uniform design!
