Raw material preparation: Paper material selection: High strength corrugated paper, honeycomb paper, and recycled paper are mainly used. High strength corrugated paper has good compressive and cushioning properties, providing sufficient structural strength for coffins; The unique honeycomb structure of honeycomb paper makes it lightweight and has strong load-bearing capacity; Recycled paper embodies the concept of environmental protection, reducing the consumption of natural resources by recycling waste paper. Auxiliary materials: Prepare natural and environmentally friendly glue, which is non-toxic and harmless, and will not cause harm to the environment and human health; Meanwhile, according to the design requirements, prepare an appropriate amount of high-end fabrics, decorative pigments, gold foil and other materials. Paper processing and molding: Cutting and creasing: Cut the selected paper according to the design dimensions to ensure that the edges of the cut paper are neat and the dimensions are accurate. Perform indentation treatment on the cut paper material for subsequent folding and forming. The depth and position of the indentation need to be precisely controlled according to the structural design of the coffin. Composite: For multi-layer paper coffins, it is necessary to composite different layers of paper materials with glue. During the composite process, it is important to ensure strong adhesion between the paper materials and avoid delamination. Molding: The soaked pulp is molded and wrapped around a processed frame, or multiple layers of corrugated paper, honeycomb paper, etc. are directly glued together through molds to form the main structure of the paper coffin. The coffin body and lid are made of multiple layers of corrugated paper glued together according to molds. The coffin body and lid are respectively made with one end high and one end low, the high end wide and the low end narrow. The bottom of the paper coffin is large and the top is small. The bottom of the coffin lid is made with a protruding stop to match the inner cavity of the coffin body. The top surface of the coffin lid is a convex circular arc, and the outer sides of both ends of the coffin body are made with concave conical cavities. Drying and painting: Drying: Place the molded paper coffin in an appropriate environment for drying to fully solidify and dry the pulp, increasing the hardness and stability of the paper coffin. Coating: Coating the surface of the paper coffin to increase its smoothness and waterproof performance, improve the service life and aesthetics of the paper coffin. Decoration and assembly: Decoration: Decorate the coffin as needed, such as painting the surface, pasting patterns, using pressed grooves inside to enhance transportation stability, and covering the exterior with high-end fabrics such as purple pink gold velvet. Assembly: Assemble the coffin body, lid, and other components to ensure a secure connection and good sealing. quality testing: Appearance inspection: Check whether the appearance of the coffin is flat and flawless, whether the fabric coverage is uniform, and whether the decoration is clear and complete. Structural strength testing: Conduct a load-bearing test on the coffin to ensure that it can withstand the weight of the body and the pressure during transportation. The testing method can adopt methods such as simulating vibration and impact during transportation. Environmental testing: Check whether the materials used in the coffin meet environmental standards, whether the glue is non-toxic and harmless, and ensure that the coffin will not cause harm to the environment and human health during use. Packaging and Transportation: Packaging: Use transparent plastic bags to package coffins that have passed inspection to prevent contamination and damage during transportation and storage. Transportation: Transport the packaged coffin to the designated location.
