Extrusion Plastic Machinery

Type:GRT 90-12L Ⅱ/3 (two station, three die head)

Max.product volume: 2-2.5L for three die head construction

**Extrusion system

Screw: specially designed based on material’s trait, High quality nitriding steel 38CrMoAlA,with nitriding surface HV≥800,brittleness≤2;Barrel: High quality nitriding steel 38CrMoAlA,with nitriding surface HV≥900,brittleness≤2;Drive mode: inverter + hard gear surface decelerator;Heating mode: porcelain heaters;Temperature controlling: automatic temperature control model;Mode of cooling: automatic fan cooler.

**Die head system

Central incoming die head, totally eliminating the converging line of products, the surface is colorful and uniform; this die head is able to be used to match polyethylene, polypropylene and so on;According to the different product, there is one series of die head for choice, such as double die (center distance: 150mm), Tetra-die (center distance: 80mm)Heating mode: stainless steel heaterTemperature controlling: temperature controlling model;Clamping systemDouble bar horizontal motion structure in moving, opening and closing mold, making the clamping force equally distributed, so the cut is smoother.Redesign in accordance with the molding requirement of the sample for efficient productivity.Frame: it’s able to move up and down.Hydraulic system

Adopted proportional pressure controlling, with hydraulic valve of Japan Yuken and pump of Taiwan Sensor, balanced and accurate action, prolonged useful life, sensitive response.

**Electric controlling system

Program controlling with Japan Mitsubishi PLC; complete machine communication, parameter setting / modification and menu displaying with the Taiwan Hitech liquid crystal display and touch screen; every parameter could be set and modified directly with the complete obstacle self-diagnosing function, menu operated directly and conveniently.Extrusion motor with the inverter controlling and alloy hard gear surface decelerator driving, saving power, lower noise, balanced and stable screw rotation.Safety configuration: safety door, safety switch protection.
