IRWIN specializes in lost wax casting for smooth surfaces, fine internal features, thin walls and small-batch production.

To enhance production efficiency, we employ automation and conduct multiple CFD tests with various mold pour locations to identify the best pour location. Furthermore, we introduced a finer grain of stucco in the stucco process to enhance the smoothness of the surface and reduce the amount of time spent in post-casting work.

IRWIN has been engaged in the process of lost wax investment casting since 2005.
Leveraging our network of investment casting partner foundries, with extensive expertise spanning over 50 years, we guarantee a perfect match to your precise requirements.
