    摘要: A method for reducing green roughness of a braking system and a method of manufacturing a brake system includes coating at least one of the components of the brake system with a boundary layer material. The method is applicable to either the pad of a disc brake system or the brake drum lining and/or the brake shoe of a brake drum system. The coating is either a binder, a filler, a boundary layer lubricant or a mixture thereof. The coating hereof is either graphite, molybdenum disulfide and/or a divalent fluoride, either organic or inorganic. Likewise, a thermoset paint such as an alkyd resin, phenolic resin, epoxy resin or the like can be used for the coating material. The coating eliminates uneven transfer of friction material during the brake wear-in period which creates brake torque vibration which, in turn, increases vehicle sensitivity and brake roughness.

    摘要: In a combined injection-molding and pressing machine according to the present invention, an injector (10a) of horizontal injection apparatus (10) is disposed below a stationary die plate (2) of a vertical press (1), an injection nozzle (10b) of the injector (10a) is formed into an L-shaped, and the injection nozzle includes a valve (10c) for opening and closing a resin passsage. Corresponding to extension and contraction of the horizontal injection apparatus (10), a base (14) of a platform (4) mounting thereon the horizontal injection apparatus (10) is allowed to slide about the injection nozzle (10), and the L-shaped injection nozzle (10b) is caused to contact with a lower mold (3) at a predetermined surface pressure. Therefore, color changing and purging of resin is more efficient and complete. No need of a hot runner permits to employ an inexpensive and versatile mold that is more widely used in common. Since resin is surely loaded through the short resin passage, molding with stable quality can be produced. Even when the horizontal injection apparatus (10) extends and contracts, the lower mold (3) remains immobile and no resin is leaked. Further, the injector (10a) can be moved outwardly away from a position below the stationary die plate (2), which facilitates replacement and/or inspection of the injection nozzle (10b), a screw and so forth.
