HPM series high-pressure foaming machine is zhangjiagang strength and industrious Machinery Co. Ltd following the international latest high technology and according to word wide the PU industry that independent innovation high technology products. The main parts are import from foreign country, equipment technical and safely performance are reached the word wide advanced capacity. The equipment is widely used automobile industry, insulation industry, air conditioning industry, electric appliance industry and furniture industry and so on. Also, expanding the application field.
HPM high -pressure foaming principle
Both Polyol and Isocyanate are stored separately in two tank, and used two rotary axial metering pumps to take material to mixing head, two components injection to a small mixing room at high pressure and flow rate when mixing head started in the hydraulic control, and collide with each other instantly, pass moving transformation that reached to mixing and flow to mold control, after pouring output time that mixing head piston rod forward, all material are pushed to mixing chamber and mixing chamber is cleaned by piston rod, don't left any material. Component passed beside of piston rod return to material tank. If it don't inject in a long time, low-pressure recalculation switchover unit but two-control component into low recalculation.
Because of equipment' exact calculation, has a small loss and needn't clean and it will be good at environment-protect and reduce the material costs. In the all areas that is to be more and more widely used. The HPM350 type high pressure foaming machine is mainly used for the insulation pipe industry to produce under-grounded insulation pipes which is prefabricated with PU andjacketed with HDPE/steel pipe. The pipe produced by the HPM350 machine is meetthe CJ/T114-2000 (neq EN253: 1994), standard of Town construction industry of China. Advantages of the HPM machine:
The main parts such as metering pump, high pressure mixing head, pressureswitches, high pressure pipe & fittings, Electric system PLC element, etc. Are imported from developed country, technical performance as well as the safety performance is better.
Certification is meet GB150-1998 Standard for the pressurized vessels, such aspoly/pentane container and isocyanate container.
Such key parts as metering pump, high pressure mixing head, PLC etc. Are imported, So its with high performance and reliability.
