3. Single cylinder: The barrel material is 38CrMoAl high-grade nitride steel, with internal surface nitriding and a thickness of 0.4-0.6mm. Full channel sandwich insulation.
4.Die head: Adopting alloy steel integral casting, with built-in channel insulation, and hard chrome plating after CNC machining.
5. Reducer: Customized extruder specific reducer, with integrated gearbox and positive and negative gearboxes, low noise, compact structure, and reduced footprint.
6. Cleaning method: Dual machine cylinder, single machine cylinder, and mold head can be automatically pushed or opened by the oil cylinder, making it convenient for material cleaning

Product Usage
Purpose: To carry out constant temperature mixing and extrusion of pre formed sheets of materials that have been mixed by an internal mixer, suitable for rubber foaming, CR foam, EPDM foam, SBR foam, diving materials, EVA, PE, PVC, etc.Working.
Principle: The twin-screw extruder is used for forward conveying, forcibly pushing the material forward. The meshing of two screws in a twin-screw extruder produces strong shear force on the material, while the long screw penetrates deep into the barrel to force feeding and extrusion. After plastic deformation of the mold head and mouth mold, the production process requirements are completed.
