Less after-treatment of MDF boards

28/04/2016
Newly developed tool from Kyocera Unimerco helps seal the edge of machined MDF boards, ensuring with less preparation and fewer painting processes you can achieve a great paint finish.

The new tool from Kyocera, named EQS, saves after-treatment on the edges of MDF boards, where customers often see fibre swelling, Egon Vingtoft, Sales Manager in Kyocera Unimerco, explains. 

 

- When MDF boards are milled, unfortunately, the fibres tend to swell like on a stiff brush. If you want the edge to have a surface of the same quality as the board, expensive priming and painting are required before you can topcoat the edge. With EQS you can reduce the high after-treatment and priming costs, Egon Vingtoft says.

 

The revolutions of the EQS tool creates friction, which heats up the paraffin of the MDF edge, pushing the paraffin in front of it. This means that first, the tool puts down the fibres and next, the holes are sealed.

 

- The tool uses the material’s own basic content to fill out. This increases the quality of the edge surface, which means several priming processes as well as after-grinding can be avoided. When the edge has a contour that requires hand sanding, you can achieve very large savings, Egon Vingtoft says.  

 

EasyCut and EQS

Harder centre core

The EQS tool also hardens the middle layer of the MDF edge.
- EQS not only makes the surface edge look and feel smoother, it also increases hardness and strength. That reduces the risk of the edge eventually cracking, Egon Vingtoft says.

 

Combining EQS with EasyCut for profile milling

In order to benefit fully from the EQS tool, prior to smoothing, you should use the milling cutter EasyCut, Kyocera Unimerco stresses.

 

- The EasyCut milling cutter is good for cutting the fibres as short as possible. EasyCut uses two edges: First, a roughing edge removes most of the material, and subsequently, the final surface is made using the finishing edge. In this way, EasyCut prepares the material well for the EQS tool. Moreover, EasyCut increases the feed rate, Egon Vingtoft explains.
