Multilayer Hot Press Machine
Providing Reliable Multilayer Hot Press Machine Solutions
Our JHC Series Multilayer Hot Press Machine, or the discontinuous polyurethane sandwich panel production machine, is designed not only for the production of insulated panels but also for doing so with the utmost efficiency. This machine injects foam between layers of boards, fully curing the board while heating, during production. Even with a more competitive price point, a reduced machine footprint, and lower power consumption, while delivering only slightly lower production capability than 2+2 hot press machines and continuous production lines, it is the best choice for sandwich panels designed for cold storage rooms or other highly insulated buildings.
Most Trusted China Polyurethane Equipment Manufacturer
Zhejiang Henghui Machinery Co., Ltd., founded in 1999, is the first company to manufacture polyurethane equipment. With an ISO 9001:2000 quality standard certificate by 2003, a production rate of more than 100 sets of polyurethane equipment per year, and 2500+ operating global systems, it is a leading enterprise in the field. Our engineers, with years of experience, aim to provide the best, most reliable production system to meet customer needs.
JHC Series:
High-Efficiency Multilayer Hot Press Machine for Polyurethane Sandwich Panel Production
The JHC Series is a state-of-the-art polyurethane sandwich panel discontinuous production system that integrates multilayer hot-press machines. The system produces foam, which is injected into layers of board, which are subsequently heated and cured in place. The process is discontinuous, highly efficient, and best suited to the production of polyurethane sandwich panels, which are frequently used in the construction of cold storage rooms and other buildings that require high-performance insulation. While smaller in stature and operating with less input than continuous production lines and 2+2 hot press machines, Series JHC remains highly reliable.
How It Works:
The JHC Series is manufactured using a discontinuous foam-injection, heating, and curing process. In foam injection, a polyurethane foam is injected into each board layer, one at a time, on-site, ensuring even distribution throughout the board and efficient use of the proper material.\par
During heating and curing, the foam-filled layers are heated with a carrier plate to allow the polyurethane to effectively cure and bond, forming a strong, durable composite.
The process is synchronized using a rack-and-pinion system. This system allows the carrier plate to descend freely and evenly, ensuring that sufficient pressure is applied to each layer and that the final product is of uniform quality throughout. \par
The advanced electrical and hydraulic systems of the production line control the opening, closing, and heating of the laminator to ensure smooth production. The entire production process is automated, enabling the manufacturing of composite panels with a high degree of insulation and internal strength. Because of these insulating properties, the panels are well-suited for use in the walls of cold storage rooms and throughout high-insulation buildings.
