What are the advantages of high pressure foaming machine compared with low pressure foaming machine?
Original foaming process: manual mixing, material filling into the water tank. This is the most original foaming process, has been basically eliminated, only a small amount still exists in the workshop. With the development of low pressure foaming machine, the foaming process has been upgraded from pure manual to semi-automatic casting production, which can be produced almost without tooling. Due to the material ratio of the low-pressure foaming machine is not adjustable, the mixing pressure is low, the flow is small and other problems, the closed cell rate of the foaming material poured out is low, the insulation effect is not good, and the multiple pouring can only complete a water tank, so the foam inside the water tank is shrinking, especially the position of the pipe mouth, and there will be cracks in winter. Manufacturers have to increase the density of free bubbles to reduce cracking problems. Through the material of foaming plug, the composition of mold release agent and other aspects to increase the thickness of tube mouth crust, although reduce the appearance of cracking, but still can not fundamentally solve the problem of shrinkage.
With the development of the industry, larger enterprises generally purchase high pressure foaming machine, good foaming mixing effect, high closed cell rate, good insulation performance, reduce cracking. Guangdong Fuleite Mechanical and electrical Technology Co., Ltd. is located in Shenghui North Industrial Zone, Nantou Town, Zhongshan City, Guangdong Province, is a set of research and development, production, sales, after-sales service in one of the polyurethane machinery automation production enterprises. The department of research and development manufacturing all kinds of polyurethane foam casting machine, polyurethane foaming machine, automatic production line (suspension line/trajectory/disk line, etc.), automatic foaming mold mold frame, the polyurethane foam of complete sets of equipment, such as mechanical arm to help thousands of polyurethane products production enterprise users to "high rate of good products, low equipment fault rate.
