摘要： An improved device for making plastic articles from resin and an improved runner block assembly for a mold for making plastic articles from resin have been made by providing a runner block assembly having at least one channel wherein the channel has a cross-section with two opposite sides having a length substantially less than the two other sides thereby forming a thin, flat channel sufficient to provide shear resistance resulting from forcing resin through the channel; means for connecting the channel to a plurality of mold cavities, and means for supplying resin to the channel. Plastic articles are made from resin in a heated mold assembly wherein heated, flowable resin is passed under pressure from a resin supply means through a flow passageway to a mold cavity, the improvement comprising, passing the heated, flowable resin into a runner block assembly wherein the flow passageway is at least one channel connected to the resin supply means, the channel extending from the resin supply means to the mold cavity and having a large heated surface with a thin, flat cross-section sufficient to provide shear resistance resulting from forcing the resin under pressure through the channel; heating the resin in the channel of the runner block assembly at a temperature of about at least as high as the temperature of the mold but less than the decomposition temperature of the resin; and passing the heated resin into the mold cavity. A typical resin is a phenolic resin containing 20% glass fiber filler.

摘要： A handle assembly for use with doors of household refrigerators includes an elongated stiffener member in the shape of a channel having a base and projecting sides. A number of apertures are spaced along the base. Each end of the member is formed with offset portions. A body of thermoplastic elastomer having a Shore A Durometer hardness of no more than about 50 is injection molded about the stiffener member. The elastomer fills the apertures and surrounds the offset portions.
