1、 Natural characteristics of paulownia wood: lightweight, moisture resistant, and stable Lightweight and high-strength, easy to transport Paulownia wood has a low density, only one-third of oak wood, but has moderate mechanical strength and good bending resistance. This characteristic significantly reduces the weight of paulownia wood coffins. Natural moisture resistance, corrosion resistance, and insect resistance Paulownia wood has a loose fiber structure, but its cell walls are rich in tung oil, which naturally provides moisture resistance and corrosion resistance. Experimental data shows that untreated paulownia wood decays more than 40% slower than ordinary pine wood in humid environments. In addition, the scent of tung oil has a natural repellent effect on termites and pests, reducing the need for anti-corrosion treatment. Warm touch, natural texture The paulownia wood grain is straight and uniform, with a light and soft color, and a warm and delicate touch. Its surface does not require complex coating, only requires clear varnish or tung oil treatment to display natural wood grain, which conforms to the concept of "returning to nature" in traditional funeral culture. Material selection and preparation: Select paulownia wood with suitable growth cycle and no serious defects to ensure that its material meets the production requirements. Dry paulownia wood to achieve a moisture content of 8% -10% to prevent deformation during subsequent processing and use. Cutting and shaping: According to the design size of the coffin, cut out the wooden battens required for the coffin cover, bottom and side panels. The wooden slats are placed side by side with the shaping frame, and then screwed and fixed after applying glue to form the basic frame of the coffin. Production of mortise and tenon structure: At the junction of the coffin, such as the joint between the side panel and the head and tail panel, a mortise and tenon structure is used for connection. The mortise and tenon structure enhances the overall stability of the coffin through the tight fit of tenons and mortises, without the need for nails. Assembly and reinforcement: Assemble the cut wooden boards into the shape of a coffin according to the design, and fix them using mortise and tenon joints or other connection methods. Add wooden keels or other reinforcement materials as needed inside and outside the coffin to enhance its load-bearing capacity and stability. Surface treatment and decoration: Polish the surface of the coffin to remove burrs and unevenness, making it smooth. According to the requirements, spray primer or perform other decorative treatments on the surface of the coffin, such as carving patterns, pasting wood veneer, etc. Installation of internal facilities: Install a height adjustable wooden bed inside the coffin to accommodate the deceased. Lay a layer of straw or other soft material on the wooden bed and wrap it securely with fabric to enhance comfort. Quality inspection and finished products: Conduct quality inspection on the completed coffin to ensure its structural stability and absence of defects.

Install handles and other auxiliary facilities for easy handling and use.
