How to Avoid Veneer Warping During the Drying Process

Why veneer warps and waves

Warping of veneer Warping of veneer is caused by different factors. One cause of this is uneven drying. If veneer dries out too fast on one side, it can shrink and warp. Poor storage is another factor that can lead to warping. Veneer that is not stacked properly or kept in a humid place can absorb water and warp. Furthermore, fluctuations of temperature and humidity may contribute to the veneer warping as well.

Properly handling and stacking the sheets during the drying process is important in order to avoid veneer warping. When piling veneer, alternate grain direction to promote consistent drying. Also, use spacers in between the sheets of paper to provide adequate air flow. Do not place veneer sheets too closely together, as this may inhibit air to all surfaces of the sheets.

Need for regular air flow in order to prevent veneer from warping

If air circulation is inadequate cause of veneer warpage in drying Proper ventilation is very important to prevent veneers from warping while drying. Ensure the drying zone is well-ventilated with effective air circulation. Fans or dehumidifiers may also be beneficial to control temperature and humidity. Be sure as well to periodically inspect the drying zone to see that the air is moving properly throughout the veneer sheets.

Checking moisture content to minimize veneer distortion

Control of the humidity in the drying space is the most important to avoid deformation of veneer. Use a moisture measure and constantly check/ maintain the humidity level of the veneer sheets. The veneer is best dried to a moisture content of around 6-8%. If the moisture is too high continue drying the veneer until it meets specifications.

How to keep veneer from warping when it dries in storage

It's important to store veneer correctly so that it won't warp while it dries. Keep veneer sheets in a cool, dry area out of direct sunlight. Ensure the area where the food is stored is also clean and free of clutter. To the extent possible, keep the veneer sheets flat to prevent bending and/or twisting. It wouldn't hurt to tarp/cover the veneer to keep dust/moisture off it also.

In summary,china plywood face veneer dryer machine proper ways of veneer drying, including highly-efficient handling, stacking, air drying circulation, monitoring of moisture content and storing, should be employed to avoid veneer deformation. If you follow these tips from XIANGYING, you'll be well on your way to ensuring your veneer dries evenly, which means that it stays flat and straight for your woodworking projects.
