Popular for handheld medical instruments and electronics.What is the typical lead time for Urethane Casting?
Most projects take 7-10 business days for the first batch of 10-25 parts. This includes master pattern CNC machining and silicone mold creation.
How many parts can I get per mold?
A single silicone mold can produce 20 to 25 high-quality parts before the mold begins to degrade and lose accuracy.
Can you match specific colors?
Yes. We offer precise color matching using Pantone and RAL color systems, as well as metallic and pearlescent finishes.
What is the maximum part size?
Our maximum casting capacity is approximately 1000mm x 600mm x 500mm.
Do you provide DFM support?
Absolutely. Every quote includes a free Design for Manufacturing (DFM) review where our engineers suggest improvements for wall thickness and parting lines.
