摘要： The present invention incorporates one or more diode lasers for the high-power CO2 or Nd-YAG lasers currently used in closed-loop DMD systems. Being semiconductor-based, such devices are almost instantaneously responsive to the electrical input. As such, a DMD system driven by a diode laser according to the invention provides a much faster response compared to other sources. The faster response time, in turn, provides for enhanced dimensional control and capability to produce intricate components with better dimensional accuracy.

摘要： Direct-metal deposition (DMD), preferably under closed-loop control, is used to fabricate alloy-variant material structures which provide a combination of desirable physical and mechanical properties. Use of the invention facilitates the production of high-strength, high-wear, and impact-resistant structures which decrease the likelihood of erosion, heat checking and brittle failure in injection molds, die casting, thixomolding and other, more exotic tooling. The invention uses DMD to deposit a first material or alloy in an area exposed to high wear, such as the tooling gate area, with a second material or alloy being used elsewhere in the tool for greater impact resistance. Advantageously, the areas may be of a user-defined thickness to further improve longevity. The resulting composite material structure has mechanical properties (i.e., yield strength, hardness and abrasion resistance) which exceed that of the homogeneous compositions currently used for mold materials, thereby enhancing productivity while improving part quality in these and other applications.
摘要翻译：直接金属沉积（DMD），优选在闭环控制下，用于制造提供所需物理和机械性质的组合的合金变体材料结构。使用本发明有助于生产高强度，高磨损和耐冲击结构，这降低了注射模具中的侵蚀，热检查和脆性破坏的可能性，压铸，触变成型和其它更加异国情调的工具。本发明使用DMD在暴露于高磨损的区域（例如模具浇口区域）中沉积第一材料或合金，其中第二材料或合金在工具中的其它地方使用，以提高耐冲击性。有利地，这些区域可以是用户限定的厚度以进一步改善寿命。所得到的复合材料结构具有超过目前用于模具材料的均匀组合物的机械性能（即屈服强度，硬度和耐磨性），从而在提高这些和其它应用中的零件质量的同时提高生产率。

摘要： An automotive component including a composite casting is provided. The composite casting includes a steel member and an end cap fastened to an end portion of the steel member. A cast coupling member is cast about the end portion of the steel member including the end cap, thereby positively and rigidly securing the cast coupling member to the steel member. The automotive component can comprise an engine cradle, a control arm, an instrument panel support structure, a bumper assembly, or a twist axle. The cast coupling member is typically formed by casting-in-place aluminum about the end cap and the end portion of the steel member. The steel member is typically a tubular member, and the end cap typically includes a flange designed to provide a mechanical interlock surface with the cast coupling member. For example, the flange can have a polygonal shape, an outwardly extending member, or notches.

摘要： A metal die casting apparatus preferably comprises a plunger core and a stationary core adapted to form recesses in the casting and to densify the metal to reduce shrink porosity. The cores are located at opposite sides of a die cavity and the plunger core is moveable in the direction of the stationary core to penetrate the metal while in a partially solidified, extrudable state. The cores are suitably shaped to displace metal laterally as the plunger core advances. The apparatus is particularly suited for forming a casting comprising an enlarged region intended to define a bore completely therethrough and surrounded by dense, nonporous metal.

摘要： A method of forming metal castings includes positioning a first end of a structural member in a first mold cavity and a second end of the structural member in a second mold cavity. The first and second mold cavities are fluidly coupled to a reservoir of molten metal. A main pressure is applied to the molten metal in the reservoir to force the molten metal into the first and second mold cavities. First and second auxiliary pressures are applied to the first and second mold cavities to densify the castings formed in the first and second mold cavities. Another method for casting includes maintaining a main pressure at or less than an initial, mold-filling pressure after the first and second mold cavities have been filled. Additionally, a method for detecting whether a first mold cavity is sufficiently filled with molten metal includes monitoring a moveable element.
