Abstract: Methods of manufacturing an injection mold component are provided. The methods include printing a plurality of layers of a material into a near net shape mold of the injection mold component. The printing includes forming each layer in the plurality of layers upon another layer in the plurality of layers such that a volumetric part cavity is positioned between the plurality of layers. The volumetric part cavity corresponds to a coarse model of at least a portion of an injection moldable part. The method further includes removing material from the plurality of layers, whereby the volumetric part cavity expands to correspond to a precise model of the at least a portion of the injection moldable part and to form the injection mold component.

Abstract: Described herein is a method for extending lubricant life, comprising treating a lubricant with a lubricant additive which comprises a compound selected from the group consisting of urea, ammonium carbonate, ammonium bicarbonate, and ammonium hydroxide to neutralize acids from oil use and/or contamination by combustion condensates. For example, the lubricant of an internal combustion engine can be treated in situ with an aqueous solution of urea, ammonium carbonate, ammonium bicarbonate, and/or ammonium hydroxide. Also provided is a method for extending lubricant life, comprising use of a urea source on a vehicle that is processed and delivered on board to a lubricant to treat reactive species in the lubricant to increase oil drain interval.

Abstract: A method of manufacturing an injection mold includes providing a build plate. A plurality of layers of a material are printed onto the build plate so as to form a near net shape of an injection mold component. The near net shape of the injection mold component defines a first volumetric part cavity. Material is removed from each of the build plate and the plurality of layers so as to form a net shape of the injection mold component. The net shape defines a second volumetric part cavity. The build plate at least partially defines the net shape of the injection mold component.

Abstract: A system includes a controller, a pretreating machine, and an additive manufacturing machine. The pretreating machine is coupled to the controller. The pretreating machine includes a pretreater structured to form an interface layer on a component. The additive manufacturing machine is coupled to the controller. The additive manufacturing machine includes a material feed and a forming beam. The material feed is configured to selectively provide a first amount of material on the interface layer. The forming beam is configured to substantially melt the first amount of material, thereby forming a first layer of a first material deposit on the interface layer.

Abstract: A method of performing a cleanup service on an internal combustion engine includes draining used fleet oil from the engine, filling the engine with a first cleanup oil, draining the first cleanup oil after an operation interval, and filling the engine with fresh fleet oil. The method may further include, before filling the engine with the first cleanup oil, flushing the engine with a second cleanup oil. The first cleanup oil or the second cleanup oil may include an ester-based oil, an alkylated naphthalene and a polyalphaolefin base oil.
