Manufacturing Process of Sande Plywood
The process of manufacturing Sande plywood involves several crucial steps to transform the raw Sande wood into a finished product that is strong, durable, and moisture-resistant. Understanding the process gives insight into how the final product retains the key characteristics that make it so valuable.
Harvesting and Drying
The journey of Sande plywood begins with the harvesting of the Sande tree, which is carefully selected to ensure it meets the required standards. After the trees are felled, the logs are transported to specialized mills, where they are debarked to remove the outer layers. The remaining wood is then sliced into thin veneer sheets. These sheets are placed into drying chambers to reduce the moisture content, a step that ensures the plywood does not warp or buckle during use. The drying process also helps improve the adhesive bonding in the final plywood.
Bonding and Layering
Once the veneer sheets are prepared, the next step is to arrange them in layers. The key to making plywood is the alternating of grain directions between layers. This method, known as cross-lamination, increases the strength and stability of the plywood, reducing the risk of bending, twisting, or warping. For Sande plywood, this layering process is particularly important, as it helps to enhance the plywood’s moisture resistance by ensuring that the adhesive used to bond the layers is evenly distributed.
The adhesive used for bonding in Sande plywood is specifically designed to hold up against moisture and environmental stress. The adhesive also ensures that the individual sheets of veneer are firmly secured together, resulting in a final product that is resistant to delamination.
Finishes for Sande Plywood
Sande plywood is available in several finishes, depending on its intended use. The most common finishes include:
- Smooth Finish: This finish is typically used for applications where a sleek, polished surface is required, such as in furniture making or interior design projects.
