Spring-loaded ejectors for wood strand molding
摘要:
Mold apparatus and method of production and ejection of molded wood strand three-dimensionally curved articles of manufacture, molded from a loosely felted flake mat, using an ejector pin assembly within said mold apparatus having ejector pins with pin head diameters of at least about 0.750 inches or greater, that exert a loaded ejector pin pressure of from approximately about 100 psi to about 1000 psi, to eject the molded wood strand article from the mold apparatus without causing excessive indentation and densification within the mat during mold processing.
