American style wooden coffins have become a highly representative category in global funeral culture due to their solemn and elegant design, exquisite craftsmanship details, and diverse material choices. Its production process not only continues the essence of traditional woodworking skills, but also integrates the standardized process of modern industrial manufacturing, forming a unique production system.
The wood selection for American coffins is mainly hardwood, commonly including oak, walnut, cherry, maple, etc. These woods have high density, clear texture, and strong corrosion resistance.
Drying treatment: The logs need to undergo steam hot pressing drying (with a moisture content reduced to 18% -22%) and secondary equilibrium kiln drying (with a final moisture content controlled at 8% -12%) to eliminate internal stress in the wood and prevent cracking and deformation of the finished product through gradient moisture control.
Grading screening: A spectral scanner is used to digitize the density and texture of wood. Grade A wood is used for visible surfaces such as coffin lids and side panels, Grade B wood is used for frame structures, and Grade C wood is used for internal support components, achieving a balance between resource efficiency and aesthetic value.
Anti corrosion treatment: Vacuum pressure impregnation of wood with anti-corrosion agents or application of environmentally friendly wood wax oil to enhance insect resistance and weather resistance.
Structural technology: dual guarantee of mortise and tenon and mechanical reinforcement
The structural design of American coffins emphasizes stability and sealing, combining traditional mortise and tenon techniques with modern mechanical reinforcement technology to form a unique structural system.
