Frequently Asked Questions (FAQ)
When should I switch from pure CNC machining to Casting + CNC?
The decision usually comes down to volume and material waste. If you are machining complex parts from a solid block (billet), you are paying for material that just ends up as chips on the floor. Switching to casting cnc machining makes sense when your production quantities justify the initial tooling cost. By utilizing near net shape manufacturing, we cast the part close to its final form and use secondary machining operations only for critical features like sealing surfaces or threaded holes. This hybrid approach significantly lowers the per-unit cost for medium to high-volume runs.
How do you handle porosity in machined areas?
Porosity is a primary concern during post-casting machining, as uncovering a void can scrap a finished part. We tackle this early in the DFM analysis phase by optimizing gate placement and cooling rates to push potential porosity into non-critical areas or overflow tabs. For high-stress applications, we verify internal integrity using X-ray inspection before machining begins. Understanding the material density differences is crucial; for instance, knowing the advantages and disadvantages of high-pressure die casting versus investment casting helps in selecting the right process to minimize porosity risks in your specific application.
What is the lead time for tooling vs. production?
Tooling is the initial hurdle, typically taking a few weeks for design, fabrication, and sampling depending on the complexity of the mold. Once the tooling is approved (T1 sample), production moves much faster. As your OEM manufacturing partner, we handle the entire workflow—from the foundry to tight tolerance machining—under one roof. This vertical integration eliminates the lag time usually caused by shipping parts between a casting house and a machine shop.
