Whether cold press can be changed into hot press and how to avoid slow temperature rise

1. What is the current way of heating the hot press? The specific answer given by the hot press manufacturer is: In the heating work of hot press, the electric heating rod is embedded in the hot pressing die or hot pressing plate to directly heat. Although it has the advantage of less heat loss, the heating is uneven and the electric heating rod is easy to be damaged. Therefore, the use of heat-transfer oil heater to indirectly heat the hot pressing die or hot pressing plate can avoid these shortcomings and problems, but the heat loss is slightly larger.

2. Multi layer hot press, can it be used to produce multi-layer plywood? The multi-layer hot press is one of the hot presses. According to the introduction of the hot press manufacturer, it is used to press multi-layer plywood, particleboard and fiberboard of various densities, and can press multiple sheets at the same time each time. In terms of pressure selection, it can be hydraulic pressure and steam pressure.

3. Cold press, can it be changed into hot press? Hot press in the hot plate, generally what material? The cold press can be changed into a hot press, as long as the upper and lower pressing plates of the cold press are opened with a hot runner, and an additional electric heater of heat conducting oil is provided. In the hot runner is a circulating heat conducting oil to heat the pressing plate. The hot pressing plate in the hot press is generally made of aluminum alloy plate and cast iron for the lifting table.

4. During the use of plywood hot press, how to avoid the problem of slow heating speed? Plywood hot press, this is one of the hot presses. In the process of use, if you want to avoid the problem of slow temperature rise, the hot press manufacturer thinks that it is necessary to do the following work: the steam pressure should be within the proper and normal range, the steam bag hole and return water should be kept smooth, and there is no sundries attached to the equipment.
