Regulations on processing technology

The deformation of EPC casting shall be loaded according to the cargo capacity required by the machine equipment, overweight is allowed. The diameter of steel ball is 0.3mm up down.

The time of shot blasting depends on the size appearance of the casting,

The casting parts after shot blasting are allowed to leave mold shell oxide skin.

Operation process

EPC casting level check equipment operation condition is all normal.

Install the casting parts into the barrel hook of the shot blasting machine, fasten the door cover.

Open the shot blasting machine according to the requirements of the machine equipment, carry out shot blasting rust removal for the casting parts.

According to the regulations of casting parts, after a certain time of shot blasting, carry out the actual operation of shutdown according to the procedure flow required by the machine equipment.

Remove the removed casting.

At the end of the work, carefully check the damage of leaves, throwers, rain baffles other components. If the damage is serious, remove replace them immediately.

common problem

The size of the steel ball is harmful to the technological performance high efficiency of the casting, the larger diameter of the ball can exceed 0.2mm.

Stainless steel shot shall be selected when removing aluminum alloy die casting.

The size removal difficulty coefficient of each shot blasting shall be basically the same.

Dust removal equipment of shot blasting machine shall be cleaned combed frequently.

For castings with long fine holes, when the mold shell in the hole cannot be eliminated, the alloy drill can be used to drill a buried hole for the small medium-sized shell before shot blasting to facilitate the casting

Pill removal.

For castings with long fine pipe grooves font style, HF acid can be used to soak for more than ten minutes to dozens of minutes (also known as "biting acid") before shot blasting,

Use alkali to boil, alkali to explode, bubble acid to clean sand.

Do a good job in the actual operation of safety. When the door cover of the shot blasting machine is clamped tightly, it is forbidden to open the shot blasting machine; when the shot blasting machine is closed, it is forbidden to open the door cover.
