Hot Press Machine for Melamine Laminates
Qiangtong hot press machine for melamine laminates is used for producing melamine paper laminated boards such as MDF, HDF, Particle board, Plywood etc. It’s surface decorative layer lamination technology.
Because of surface overlay paper is melamine glue impregnated, so it is required short cycle hot press line to achieve the glue chemical performance to give a resistant surface of laminates.

Qiangtong Hot Press Machine for Melamine Laminates
It is heated by thermal oil and pressure usually is from 30~100kg/cm2 depends on surface texture depth.
Qiangtong hot press machine for melamine laminates is applied in the lamination of decorative melamine paper on MDF or particle board.
This hot press for melamine laminates machine can produce different types of surface texture by different stainless-steel press plate, which is widely used for furniture, cabinet, flooring, etc.
Qiangtong hot press machine for melamine laminates promoted new design press in 2018, and we called it Qiangtong 5th generation press.
Qiangtong 5th generation press uses the plate’s assembly design for body structure, which gives higher accuracy of parallelism and flatness.
Meanwhile, the higher design gives enhanced strength of mechanical characters as well as convenient transportation.
The biggest advantage is the shortest cycle time, which could be reduced to 10 seconds.
It gives a 10% higher output capacity compared to the traditional models.
Besides, the 5th generation hot press for melamine laminates has better energy saving, quite running, heat insulation, easy operation, and safety functions, etc.
It is the most promoted model of Qiangtong.
Generally, Qiangtong hot press for melamine laminates has three models; we call model D1, model D2, and model D2 plus.
Model D1 is equipped with belt conveyor loader, main hot press machine, and roller output table.
Model D2 adds a standard vacuum pad unloader based on model D1.
Model D2 plus upgrades the standard vacuum pad unloader to swing arm vacuum pad unloader.
These three models of Qiangtong hot press for melamine laminates have their advantages.
Model D2 is taking the board out of the press machine automatically compare to model D1.
So, it will protect the bottom chrome plate surface better than the D1 model.
Meanwhile, the D1 model needs people from the in-feed side to push the board out of the hot press machine for the melamine laminates machine.
If the two people push not in the same time, then the board will be easily stuck inside the machine, then people from out-feed side need to put their hand inside the open machine to take the board out which increases the danger to workers.
Because the hot press machine for melamine laminates is scalding, workers may get hurt when they put their hand inside the machine.
So, Model D2 is safer for workers and saving labor, as it protects the bottom chrome plate surface.
The hydraulic system of Qiangtong hot press machine for melamine laminates has two basic requirements: applying pressure to the workpiece and driving the hot plate to achieve a specific motion.
The stability of quick closing and holding pressure is an important indicator for evaluating the performance of hydraulic systems.
Since the heating and solidification of the glue should be completed during the pressure-maintaining stage, the fast closing speed is beneficial to both the process and the efficiency.
On the one hand, the heating of the slab under non-pressure can be reduced, and the surface of the slab is prevented from losing too much water.
Causes war page, and also prevents pre-curing of the glue, reducing the quality of the veneer; on the other hand, it can shorten the auxiliary time and increase the productivity of the press.
To make the hot press for melamine laminates hot press machine open and close smoothly, mechanical synchronizing devices are generally provided or synchronized by the hydraulic system.
