Molders have been known to degate micro parts manually using a microscope or high-definition video camera and surgical shears.
Multi-cavity approaches for micro molds are being investigated.
There are four IRHD methods in use: the normal-hardness test (dead load), high-hardness test, low-hardness test and the micro test.
A foot is used to hold the sample in place with a force of 8.3 N (dead load) or 235 mN in the case of the micro hardness tester.
Tuff has been available in its present bar form for about two years but is just now catching on.
