MICRO

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.
