Material selection is the first step in the production of wooden coffins and a key factor in determining the quality of coffins. High quality wood is the foundation for making wooden coffins, and craftsmen will select suitable wood based on the customer's needs, budget, and the purpose of the coffin. During the selection process, the integrity of the wood should be carefully checked to avoid defects such as insect infestation, cracks, and knots. After selecting the wood, proceed with the material preparation work. Cut the wood according to the size requirements of each part of the coffin, generally including the materials used for the main components such as the coffin lid, coffin body, and coffin bottom. When cutting, it is important to ensure that the grain direction of the wood is consistent. This not only improves the aesthetics of the coffin, but also enhances its structural stability.

The cut wood needs to be dried to remove the moisture inside the wood. If the moisture content of wood is too high, it is prone to deformation, cracking and other problems during subsequent use, which affects the quality and service life of wooden coffins.

Common drying methods include natural drying and artificial drying. Natural drying is the process of placing wood in a well ventilated and dry environment, allowing the wood to naturally evaporate moisture. This method is time-consuming but cost-effective, and can effectively preserve the natural characteristics of wood. Artificial drying is the use of drying kilns and other equipment to accelerate the drying process of wood by controlling temperature, humidity, and other conditions. Artificial drying is fast and efficient, but requires certain equipment and technical support. Regardless of the drying method used, it is necessary to ensure that the moisture content of the wood meets the appropriate standard, generally controlled between 8% and 12%.

After drying, the wood can enter the component manufacturing stage. Firstly, the production of the coffin body involves assembling the cut boards into the shape of the coffin body. In the process of assembling the coffin body, craftsmen need to accurately measure and adjust to ensure the size of the coffin body is accurate and the joint is tight. At the same time, the edges of the coffin should be polished to make it smooth and rounded, avoiding scratches. Next is the production of the coffin lid and bottom. The coffin lid is usually made into an arc shape that matches the coffin body to increase the overall beauty of the coffin. The bottom of the coffin should be flat, firm, and able to withstand the weight of the coffin and the body.

After the components are manufactured, assembly work can begin. Assemble the pre made coffin body, coffin lid, and coffin bottom in a certain order and process. During the assembly process, it is necessary to recheck the dimensions and splicing of each component to ensure that the wooden coffin structure is stable and well sealed after assembly.

The surface of the assembled wooden coffin may not be smooth enough and needs to be finely polished. The purpose of polishing is to remove burrs and defects on the surface of wood, making the coffin surface smoother and more even, and improving its aesthetics and feel.

Polishing work usually starts with coarse sandpaper and gradually transitions to fine sandpaper. Craftsmen will hold sandpaper and polish along the grain direction of the wood, paying attention to even force to avoid excessive or insufficient polishing. During the polishing process, it is necessary to continuously check the flatness of the coffin surface until satisfactory results are achieved. Fine polishing not only improves the appearance quality of wooden coffins, but also prepares them for subsequent painting or coating work.

Painting and coating is the final process in the production of wooden coffins, and it is also an important link in endowing coffins with unique charm and protective effects. Painting not only enhances the aesthetic appeal of coffins, but also serves as moisture, anti-corrosion, and insect proof measures, extending the lifespan of wooden coffins.

Before painting, the surface of the coffin should be cleaned to remove dust and impurities generated during polishing. Then, based on the customer's needs and the material of the coffin, choose the appropriate paint. Common paints include clear varnish, colored paint, etc. Clear varnish can preserve the natural texture and color of wood, making coffins look more natural and rustic; Color paint can be adjusted according to the customer's preferences to add different colors and styles to the coffin.

The production process of wooden coffins, from material selection and preparation to painting and coating, embodies the hard work and skills of craftsmen in every step. It is precisely these exquisite crafts that have created wooden coffins with unique cultural value and practical significance.
