The fixture/gauge design
If the trail run result is negative, and we will consider to design the fixture as below.
When the housing is just released from the mold, and the product is very heating, we
will put the housing in the fixture, and waiting for about 10-15second cooling time.
Then we can assure the HSG in the good position.
--Force the housing to be consistent, and not big change for the dimension variation
in the open mouth position.
