Processes to Fully Finish Components

In-House Finishing Capabilities

 In many cases, aluminum and zinc die cast components require secondary operations. Soldy has all the necessary equipment and expertise to deliver a completely finished product. Our secondary processes are described below.  

Trim Presses

Die casting trim dies are used to cut or shear excess aluminum or zinc (runner, overflows and flash) from the cast part. The two-piece trim die is secured in a trim press that forces the two halves of the trim die together under several tons of pressure. Trim dies, which require great attention to detail in design, are produced in-house by our experienced die makers.

CNC Machining

CNC (Computer Numerical Control) machining is used to create component features and shapes when we cannot die cast to net shape (part-to-blueprint). Our CNC capabilities include a 4-axis CNC machine, which operates on the X, Y and Z axes, and also through rotation around the X-axis (referred to as the A-axis). Our CNC machines are used not only for shaping, but also for fast and efficient drilling and tapping.

Vibro Deburring

Our vibratory finishing process involves the placing of parts, media (usually steel) and compounds into a vibratory bowls or batch tubs. The vibration exerts force on the parts that causes the media and parts to turn and grind against each other. Vibratory finishing is used for deburring, polishing, cleaning, descaling and surface preparation. Vibro deburring is a highly automated process, one that reduces labor and is able to achieve the best results for parts with close tolerances.

Shot Blast Wheelabrator

Shot blasting creates an even, textured surface on the casting, and can help with the removal of excess flash and burrs that may remain after the trim press operation. Shot blasting is an important intermediate step for the surface preparation of an aluminum casting before its surface is painted or coated.

Heat Treat Oven

Heat treating is used for aluminum die castings to anneal or age the metal. Annealing alters the microstructure of the metal, changing its mechanical or electrical properties. In addition, annealing is used to reduce hardness, increase ductility and reduce or eliminate internal stresses.
