3.Machining and processing HPL
Due to the thicker boards, some special factors have to be taken into account for machining HPL-Compact, especially when it comes to selecting suitable tools. These have to meet the highest requirements. We therefore recommend coordinating the selection of the required TCT tools, particularly for saws and routers, with the respective manufacturers. This especially applies if e.g. larger batches have to be manufactured or if higher requirements exist for the cutting quality. Appropriate prior testing is also recommended in these cases. As a rule, local overheating from improper tool guiding has to be avoided for all machining processes. Furthermore, a good extraction system has to be provided in the workplace to reduce dust pollution.
As already explained, HPL-Compact sheets are HPL sheets with a thickness of over 2 mm. They are large format sheets with a decorative, durable surface and homogeneous, closed cut edges. One or two sheet sides have decorative surfaces, which can be smooth or textured.
HPL-Compact offers the following advantages:
In thicknesses under 3 mm, HPL-Compact can be bonded to rigid supports. For self-supporting applications, rigid supports are required at shorter spacings for thickness up to 5 mm. For greater thicknesses, however, HPL-Compact sheets are usually self-supporting. Sheets with a thickness over 8 mm are suitable for large area (horizontal) use with more widely spaced supports. It is up to the user to adapt the thickness of the product to the maximum requirements according to the specific purpose.
Free-standing edges and corners of HPL-Compact always have to be chamfered to avoid injuries.
