Introduction to wooden moldings

Wooden moldings are decorative moldings made from hard, dense, and corrosion-resistant wood, processed mechanically or by hand after drying. They are characterized by wear resistance, corrosion resistance, and ease of processing. The main materials include mixed hardwood moldings, paulownia wood moldings, and ash wood moldings. Functionally, they are divided into panel moldings, column corner moldings, and wall moldings; shape-wise, they can be divided into corner moldings, edge moldings, and decorative moldings. Their structure includes ceiling moldings, ceiling corner moldings, wall moldings, and door moldings, widely used in wall edging, surface finishing, and ceiling design.

The moisture content of solid wood moldings must be no less than 7% and not exceed the regional equilibrium value, and the formaldehyde emission must not exceed 1.5 mg/L. During installation, flawless moldings must be selected and fixed using adhesive or concealed nailing methods. When splicing, straight splicing or corner splicing methods should be used to ensure a smooth joint. With the increasing demand for decoration, the industry is gradually introducing automated production technologies, such as 45° tracking cutting equipment and contour sanders, improving processing efficiency through automated lines and MES systems. The production process of folded-edge wood trim utilizes a heat-shrink backing technique to address moisture-proofing during transportation and enables mass production of trims in various specifications. This technology has passed the Zhejiang Provincial Industrial New Product and New Technology Appraisal and Acceptance, reaching a leading level among similar technologies in China.
