Static Mixer Vacuum Resin Casting Machine

Product Description

5.6 300L hardener counting tank system: same configuration as that for Item 4.5.

5.7 High precision carborundum counting pump system, two sets

• For counting & feeding resin and hardener separately; Pumps are mounted on the side wall of counting tanks. Each counting pump is comprised of ball screw, servo motor, servo driver, etc. Torque of servo motor can satisfy for pumping viscosity max. 8000mPa.s.
• Counting pump body is made by high quality carborundum from Germany, life more than million times feeding.
• Feeding speed 5-10kg per minute, counting precision +/-0.5%; Various casting proportion can be achieved and displayed on displayer for convenient adjustment.
• Quantification feeding, preset and controlled by PLC; All main valves are interlocked for safety.
• When the whole machine stops, counting pump will timely cycle materials for cleaning pipeline and mixing material.

5.8 Static mixer system, one

• Static mixer and casting system are mounted on top of casting tank. Static mixer is comprised of 15 pieces cross mixing blocks. After obtaining pressure from counting pump, material inside this mixer will have cross mixing for more than 100 million times. Flow speed matches the counting pump.
• Static mixer has quick temperature rising and quick cooling functions. When start working, mixer temperature can be raised to max. 90C very quickly; After casting finished, mixer can cool down to 15-25C very quickly thus delaying curing speed of two components.
• When changing casting material without stuffing, only change few parameters, very simple and convenient.
• Our design can avoid any small leakage because of wearing. There is real-time supervision function to assure reliable and stable running.

5.9 Vacuum casting tank

• Inner dimension: 2400mm (diameter) 3000mm (length)
• Round structure, horizontal laying
• Door side opening, hanged on one side of tank; manual lock
• Ultimate vacuity: less than 10Pa (idle, cool)
• Leakage rate: less than 50Pa.L/s (idle)
• Working vacuity: 100-300Pa
• Pumping speed: not more than 15 minutes from atmosphere to working vacuity
• Heating method: state-of-the-art electric heating plate method, heating plate from Germany;
• Heating temperature: ambient temperature to 120C (automatic adjustable, constant temperature, over-temperature alarming), temperature evenness 2C
• Tank body is rockwool insulated and stainless steel armored, outer surface temperature rise is not more than 10C plus ambient temperature.
• There are 12 sets pneumatic valves and injecting nozzles for casting. Injecting amount of every nozzle can be preset. The whole injection can be PLC control automatic or manual; Pneumatic valves are anti-wear treated, avoiding interior leakage. After whole casting finished, the static mixer and whole system can be cleaned by one single component.

5.10 Heating system, four sets

• Casting tank is heated by Germany heating plates, total power 48kW
• Each mixing & degassing tank and counting tank are heated by electric heater and transferred by mesotron, each 9kW;
• Static mixer and material transmitting pipeline share one electric heater, power 9kW
• Stuffing drying tank is heated by Germany heating plates, total power 18kW
• Each heating system adopts power-control module assuring temperature even and stable. Electric consumption in temperature-keeping stage is about 35% of total power, save energy.
