FAQ
What is jewelry investment casting?
It's a process for creating complex and detailed jewelry by injecting molten metal into a ceramic mold formed around a wax model.
What are the advantages of investment casting?
It can produce jewelry with extremely complex shapes and fine details, and allows multiple identical pieces to be cast from one mold, making it ideal for small batch production.
What is the investment casting process?
Key steps: Create a master pattern → Make a rubber mold → Inject wax to form a wax tree → Build ceramic shell → Melt out wax → Cast molten metal → Break shell and finish.
What metals can be used for jewelry investment casting?
Almost all jewelry metals can be used, most commonly Silver (Sterling), Gold (various karats), Platinum, and Bronze.
Is the surface of investment cast jewelry smooth?
The raw casting has a rough "casting skin" and is not smooth. It must be finished through processes like filing and polishing to achieve a shiny final appearance.
Can investment casting be used for custom jewelry?
Yes, this is one of its primary uses. It's ideal for both one-of-a-kind custom pieces and limited edition designs that need replication.
Is investment casting expensive?
For a single piece, initial costs are relatively high (due to master and mold creation). However, the per-piece cost decreases significantly when producing multiple identical items.
How is 3D printing used in investment casting?
High-resolution 3D printing is now commonly used to create wax or burnable resin patterns directly, replacing hand-carved wax and greatly enabling complex designs and rapid prototyping.
What are common defects in investment casting?
Common defects include gas porosity (small bubbles in the metal), misruns (metal fails to fill all details), and shrinkage cavities.
Why is it called "lost wax" casting?
Because the core of the process is that the ceramic mold is heated to melt and completely "lose" the wax model inside before casting, creating the cavity for metal pouring. "Lost wax" describes this disappearance of the wax pattern.
