Patent US6053225 - Wood molding process - Google Patents25 Apr 2000 ... Making a round timber into a square timber by compression molding is another common practice. These wood molding processes are accomplished in any of the following ways. (1) Softening by microwave heating and subsequent molding, followed by several repetitions of slow cooling and rapid secondary heating with the molded configuration retained for relieving internal stress due to molding. For example, molding round timber of Japanese cedar into square ...【Get Price】

Compression molding - Wikipediacompression Molding is a method of molding in which the moulding material, generally preheated, is first placed in an open, heated mould cavity. The mold is closed with a top force or plug member, pressure is applied to force the material into contact with all mold areas, while heat and pressure are maintained until the molding material has cured. The process employs thermosetting resins in a partially cured stage, either in the form of granules, putty-like masses, or preforms.【Get Price】

Wood-Plastic Composite Fabrication - Appropedia: The ...Traditionally, wood-plastic composites were fabricated using compression molding. The disadvantage of using this process in the manufacture of WPCs is that any part created takes a general form. This means that additional manufacturing processes, which tend to be wasteful and expensive, are required to produce a finished product. Due to these material and energy inefficiencies during production, the compression molding process is not ...【Get Price】
