In accordance with CO2 foaming process environment, we design and develop single-screw secondary extruder with 2-way and igh cooling efficiency. Single-screw design has good effect on large cooling area coverage. Its process multi-stage kneading low shear heating, melting temperature homogenizer, low-speed but high throughput 500 kg/h speed only 3.6 rpm. Automatic temperature control system with multiple points on integrated design of 2-ways heat exchange and with a special design of the secondary efficient cooling extruder screw, it is able to regional peer-to-peer rapid cooling heat exchange. According to the set process parameters PID self-tuning adjustment, its precise temperature control can be within±1℃

CO2 foaming agent automatic injection system
1, high pressure and low temperature metering pump station 2, mass flow calculation system 3, automatic cycle constant liquefaction device 4, liquid static mixing device 5, stainless steel high pressure anti-corrosion connection, pipe fittings 6, computer control system 7, low temperature transport system 8, buffer high-pressure and low temperature tank (with CO2/ethanol)
stacking unit
1, stack size: 1200-2400mm*600mm*900mm 2, lift motor power: 3kw 3, transmission motor power: 0.37kw 4, speed control mode: frequency conversion speed
Mold temperature cotroller
The heat conduction medium with high heat conduction is used to control the temperature rise of the die in a very short time. After setting the heat balance temperature, the mold temperature can automatically control its temperature within the minimum error and maintain the fixed value.
FAQ
Q：What’s the thickness range of the boards? A：Our full series of lines can produce from 10-200mm thickness directly. However, each model has its own suitable range, therefore thickness range of targeting market is the key determining factor when selecting machine. Q：What is the width range? A：The international standard width is 600mm, some countries have 1200mm and 900mm width. In principle, any width can be produced by changing die or adding slitting machine. Q:how can we guarantee quality? A: Always a pre-production sample before mass production; Always final Inspection before shipment Q: What should we prepare except material? A: You should prepare workshop, water line, electric line, compress air (if you need, we can help you buy air compressor). We can supply workshop layout drawing according to your workshop. Q: Where is your factory located? How can I visit there? A: Our factory is located in Longkou city, Shandong province, you can fly to Yantai or Qingdao airport, Yantai airport is nearer than Qingdao airport.
