发明名称 Manufacturing method for cosmetic pens with wood sleeve uses spacer cartridges glued between timber plates and melted out to form mold for pen cartridge
摘要 The pen cartridge is cast into a wood sleeve, which can be sharpened. During manufacture, two spacer cartridges with relatively low melting point are glued between two formed timber plates, and pens are fabricated in the conventional manner. During a subsequent drying/heating process, spacer cartridges are melted out, and the wood sleeves are used as a mold for casting of a cartridge. The spacers are of a wax material, are manufactured by extrusion, and after melting, a thin insulating wax layer remains on the inner sleeve surface.
