CNC machining after high pressure die casting

Tight tolerances for your high pressure die cast parts

Do you have high requirements for assembly, surface finish or function? High pressure die casting provides a strong and cost-effective starting point, but for parts with tight tolerances, a level of precision is required that is best achieved through CNC machining.

High pressure die cast parts often achieve high quality straight from the tool, but certain features and tolerances require further machining. This may, for example, involve precise holes or surfaces that need to be assembled with other parts, or parts that must meet specific mechanical requirements.

Four ways in which CNC machining improves high pressure die cast parts

CNC machining gives your high pressure die cast parts the final finish they need to become fully finished parts with precise dimensions, fine surfaces and consistent quality. The combination of high pressure die casting and CNC machining ensures an efficient production of high-quality parts with full functionality and the correct tolerances.

Precise tolerances and fits

CNC machining fine-tunes high pressure die cast parts to tight tolerances, ensuring that parts to be assembled fit accurately. With multi-axis machining, parts can be machined down to a millimetre’s precision, minimising the risk of incorrect assembly and improving the function of the finished product.

Functional surfaces and holes

CNC machining makes it possible to produce features such as drilled holes, threads, ribs and flat surfaces directly in high pressure die cast parts. This reduces the need for separate parts or manual processing, saving time and ensuring that every part meets the design requirements.

Consistent quality in series production

CNC machines process all parts in exactly the same way, ensuring consistent quality even with large volumes. This ensures that all parts meet the same dimensional and tolerance requirements, minimising deviations and saving time during assembly.

Adaptable according to material properties

As different light metals and alloys have different properties, they require different processing to achieve the desired results in terms of tolerances and shape. With CNC machining, it is possible to adjust milling and axis movements to best suit the material undergoing machining after high pressure die casting. The end result is parts with maximum functionality and durability.

How Idé-Pro works with high pressure die casting and CNC machining

Combining high pressure die casting and CNC machining requires both processes to be carefully planned. Right from the design phase, we consider how the part will be machined after casting, in order to minimise waste, reduce lead times and ensure that the die-cast parts meet the required tolerances.

  • Thorough planning: High pressure die casting and CNC machining are coordinated from the very beginning to ensure a smooth process.

  • Correct fixturing: High pressure die cast parts require customised fixtures to maintain position and tolerance during machining.

  • Quality control: We measure and verify the parts so that deviations are detected early.
