Metal Production Die Casting
Production die casting is an excellent source for higher quantity metal casting requirements. A larger upfront tooling investment yields a significant reduction in reoccurring casting costs. Production die castings have very repeatable properties and tolerances.
Metal Soft Tool Die Casting
The term “Soft Tool” is used to describe a metal casting tool made out of P-20 steel. The P-20 steel is softer than H-13 steel and thus yields parts in less time with a decrease in tooling cost. This is attributed to the ability to run faster feed rates when CNC machining the tool. Typically a P-20 metal casting tool can yield 10,000-40,000 castings before showing any significant wear.
Metal Permanent Mold Casting
Permanent mold casting is an excellent solution for low volume metal casting requirements (1,000-5,000). A permanent mold casting looks very similar to a die casting. The main benefit of permanent mold casting compared to a die casting is a significant reduction in tooling cost.
Metal Sand Casting
Sand casting can be a good fit for mid to high quantity metal casting requirements and often the most cost effective for larger components (over 20” in any one dimension or more than 30 lbs).
Metal RP Investment Casting
Metal RP (Rapid Prototype) investment casting can be an excellent alternative to CNC machined, SLA, or SLS prototypes. RP investment cast metal casting is the only metal casting process that is both cost effective at low quantities and yields metal casting properties.
Metal Investment Casting
Production investment casting can be an excellent fit for mid to high metal casting quantity requirements. It is good for casting requirements when the geometry cannot be made using other metal casting processes. Compared with RP investment casting, production investment cast metal casting requires a higher upfront investment with a much lower reoccurring metal casting cost. Investment cast metal casting has fewer design constraints than traditional cope and drag metal casting processes.
Metal Plaster Casting
Metal plaster casting is a very similar process to sand casting, but yields a much better metal casting surface finish which is very similar to a die casting finish. Plaster casting is often used for metal casting quantities of 50-300 to prototype a future die casting. Plaster casting also has the capability of metal casting wall thicknesses as thin as .030”.
