Air hole (sand hole): the hole with regular shape and smooth surface formed by the gas involved in the die casting.M9 connector

Flow mark: on the surface of the die casting, there is a line consistent with the flow direction of the liquid metal, which can be felt by hand to be locally depressed, which is a defect

There is no possibility of development.M10 connector

Cold insulation: Joint mark caused by butt joint or non fusion of metal flow. Its intersection edge is smooth, with penetration and non penetration

Species have a trend of continuous development under the action of external forces.

Scratch: there is a certain depth of line like damage trace on the surface of the casting along the direction of casting, which is a stack of scars in serious cases.

Dent: a concave part on the smooth surface of a die casting.

Adherent trace: the trace left on the die casting due to the falling off of sheet metal or coating accumulation, if the sheet metal does not fall off,

If the local fusion has obvious metal layer on the casting, it is delamination.

Net burr: a net protrusion (or concave pattern) on the surface of the casting caused by the cracks on the surface of the mold cavity.

Bubble: the bubble formed by the gas bulging in the subcutaneous pores of the die casting.
