摘要： A coated tool or instrument has a wear-resistant hard coating (7) which is preferably titanium nitride for working organic material which is disposed on a separating layer (9) applied on a basic body (3). The separating layer (9) comprises a ceramic electrically non-conducting material. Such a material is preferably an oxide, nitride or oxynitride of silicon. The separating layer (9) protects the basic body (3) of the tool or instrument of e.g. a non-corrosion resistant steel. During the coating of the basic body (3) with the ceramic material, a pulsating dc voltage is applied to the basic body (3) or its holders. The pulse height is changed during the vapor deposition from high negative values to low negative values.

摘要： A three-dimensional master of the article to be molded is provided. The surface of the master is coated with a mold release agent. A gel coat layer is then applied to the mold release agent coated surface of the master, and cured at about room temperature and preferably no greater than 55.degree. C., until the cured surface feels slightly tacky. At least one fiber-reinforced catalyzed resin layer is then applied to the cured gel coat layer and cured. The resin layer includes a room temperature curing, low shrinkage thermosetting filled paste system including 25 to 75 percent of an unsaturated polyester resin, 1 to 25 weight percent of a mixture of thermoplastic polymers of vinyl acetate, an epoxy compound having at least one 1,2-epoxy group per molecule, and 25 to 75 percent filler. The resin is preferably cured at room temperature for about 30 minutes to 4 hours using a free radical initiator which is mixed with the resin as it is being applied. After curing, the thus formed mold is removed from the three-dimensional master.

摘要： A blow molding process of producing molded articles including the steps of extruding a parison of the plasticized material from a die into a gap between mold halves while the mold is open and blowing gas into the parison, while the mold is closed, to have the parison form a molded hollow article within the mold. The parison is heated before molding by heating the inner shell contoured parts of the mold at the surfaces thereof and the plasticized material at the outer surface by using an instantaneous radiation heater disposed in the mold half gap to partially encompass the parison while the mold is open and the inner shell contoured part is heated by a heating medium passed through the heat medium passages. The molded article is cooled by cooling the mold at the inner shell contoured parts thereof by flowing a cooling medium through the heat medium passages of the mold while the mold is closed. The cooling of the mold occurs alternately with the heating of the mold by the heating medium.
摘要翻译：一种生产模塑制品的吹塑工艺，包括以下步骤：当模具打开时，将塑型材料的型坯从模具挤出到模具半部之间的间隙中，同时在模具闭合的同时将型坯吹入型坯，以使型坯在模具内形成模制的中空制品。在模制之前，通过使用设置在模半间隙中的瞬时辐射加热器在模具打开的同时加热模具的内壳轮廓部分和外表面处的塑化材料来加热型坯并且内壳轮廓部分被通过热介质通道的加热介质加热。通过在模具闭合的同时使冷却介质流过模具的热介质通道来冷却模制件的内壳轮廓部分来模制成型制品。模具的冷却与加热介质的模具的加热交替地发生。

摘要： A mold structure including layers with different physical properties is used to provide hot surface during molding. The use of a thin layer of low thermal conductivity covered by a smooth skin layer prevents quick cooling of the surface of the pre-heated plastic to be molded. The plastic surface remains molten and flows to fill the mold during press closing, resulting in smooth surfaces even when fiber reinforced plastics are used.
