we are chinese manufacture specialized in postforming high pressurelaminate.The size is 1220*2440mm and over 300 colors.
The Postforming high pressure laminate(HPL) must be processed bythe special machine with certain requirement to the substrate andglue. We suggest: Before bulky use of Zhongxing Postforming HPL,take small samples and test them on the machine.
- Substrate and Adhesives:
The quality of Substrate has great effect on the postformingoperation. First, the rate of containing water or moisture shouldbe about 12%. Second, the substrate should be even, no warp, withwell-sanded surface, without dust or oil. The edge to be coveredwith postforming HPL should be smooth, without ridge but kept samecurve radius. It's better to use MDF in good quality. Also pleaseuse good urea-formaldyhyde resin as adhesive.
- Adhibiting:
A. Spread the glue on the plane part of the substrate. (No glue isallowed on the curved surface of the substrate)
B. Put the Postforming HPL on the substrate, put apart sufficientspace in order to carry out the postforming operation. Make it intoa whole part by hot pressure or cold pressure.
C. Push the component into the postforming machine to perform thepostforming process(If hot pressure is adopted, postforming processmust be conducted after the component cooling down to the roomtemperature.).
- Postforming process:
In the process of postforming, when the machine meet the HPL,please keep it for 5 seconds, then rotate the HPL along the bentsurface and pause 2-3 seconds at the different part of the HPL for5-6 times. When the machine turns to the dead end, press for 20seconds to ensure that postformed HPL is sticked firmly to thesubstrate.
