1. Uneven paving of raw materials

In the production process of particleboard manufacturers, whether the paving of raw materials is uniform is one of the main reasons that affects the thickness of the particleboard. If there is an uneven weight in the slab or uneven left and right paving, it will cause other problems. The thickness of the layer slabs varies.

2.Hot pressing deformation

When most Shandong particleboard manufacturers produce particleboard, the thickness deviation is caused by the deformation of the hot-pressed board. There are two general reasons: uneven heating during preheating, and the temperature rises too quickly; missing slabs are produced during the production process. , Light slab, short slab, etc.

3. Asymmetric hot pressing position

When the position of the slab in the hot pressing plate is asymmetric, the hot pressing plate cannot always maintain a horizontal state during the pressing process, thereby causing a deviation in thickness.

4.Hydraulic system position control

Multi-layer laminators generally use multiple cylinders to work at the same time. In some presses, all the cylinders are directly connected to the same pressure pipe. Their pressure is the same at any time and cannot be changed and adjusted independently, so it cannot overcome the problem. Thickness deviation caused by uneven installation, asymmetrical position of the slab in the platen, etc.
