Machining Services

Deco offers various machining services. Generally, there is very little machining that is necessary for zinc die castings. The reason is the near net shape that can be obtained during the zinc die casting process. The machining characteristics of zinc and zinc alloys are excellent and a wide range of machining processes can be used.

Due to part design, some of Deco’s customers require close or tighter tolerances than die casting can maintain. Therefore, machining plays a pivotal role in our ability to supply our customers with a ready-to-use finished product.

What is Machining?

It is a material removal process. Machining is inherently, not the most cost effective choice for a primary manufacturing process. Material, which has been paid for, is cut away and discarded to achieve the final part. Despite the low setup and tooling costs, long machining times may be required. Therefore, machining can be cost prohibitive for large quantities. As a result, machining is most often used for limited quantities. For example, in the fabrication of prototypes or custom tooling for other manufacturing processes.

Machining is very commonly used as a “secondary process”, where minimal material is removed and the cycle time is short. This is due to the high tolerance and surface finishes that zinc die casting offers. Machining is often used to add or refine precision features to an existing part.

CNC Machining

Deco’s CNC machining work-centers provide a broad range of options depending on the complexity of the casting. For more complex parts, CNC work centers produce precision accuracy with tremendous flexibility. Deco’s CNC machining capabilities include but are not limited to:

  • High-speed machining
  • Turning
  • Drilling
  • Reaming
  • Tapping

Competitive Machining

Our economically competitive machining services include dedicated cells or work-centers.  These optimized work-centers are located directly at, or very near the die casting machines. Thus, completing the additional operations immediately after the part is cast.

  • Rapid turnaround of parts.
  • Limits handling costs
  • Lowers scrap rates
  • Simplifies logistics.

Therefore, Deco’s overall costs are lower and our prices more competitive.
