Engineered Castings

The ability of a job shop to cast, machine, finish and assemble to customer specifications is essential to successfully competing. Services should include design engineering, prototype development, secondary machining, medium-to-high volume production, powder coating, wet painting, silk screening and assembly. Computer-Aided Design (CAD) Data Transfer through IGES, DXF/DXB files or modem capabilities represent an enhancement to the aforementioned services.

The Cambridge Tool & Mfg. Co. provides concurrent engineering from prototypes through production tooling using Stereolithography and Laminated Object Material (LOM). With these techniques engineering models for evaluation can be generated for evaluation in days, rather than months.

Capabilities in die casting should include casting machines that cover a range of machine capabilities, sophisticated vacuum systems, temperature stabilizing systems, X-ray inspection and spectrographic analysis. Production operations such as standard trimming, specialized deburring, contour sanding, polishing, buffing, shot blasting and vibratory tumbling are of equal importance in casting. Flexible work cells (centers) and technically trained employees are fundamental to the efficiency of machining operations leading to Just-In-Time delivery and Ship-To-Stock compliance. Mechanical assembly functions must cover a range of functions from simple hardware installation to complex subassemblies.

Control valves, electronic housings and vital stator part are among the engineered castings provided from an exceptionally large group of alloys. Aluminum alloys used in casting include additions of copper, iron, silicon, manganese, zinc, nickel and other trace elements. Typical of mechanical properties is Ultimate Tensile Strength (UTS) which covers a range 40.5 to 47.0 ksi, depending on the aluminum alloy. Densities range from 0.095 to 0.098 lb/in3.
