Investment casting connecting rod

Generally speaking, the cleaning of stainless steel casting surface can be divided into two categories: dry and wet. Shot blasting mainly uses dry cleaning methods. The key to wet cleaning method is to solve the problem of hydraulic cleaning sand, water cleaning sand, etc. The following are two kinds of stainless steel casting surface cleaning party.

Dry cleaning method is to clean the surface of stainless steel castings, mainly fusion mold precision casting parts shot blasting treatment. Simply put, shot blasting treatment is powered by air compression, so that the projectile wheel to break the surface of stainless steel castings at a certain speed to remove the surface of the sand and zinc ash. However, this abrasive cleaning method has been chosen by manufacturers and almost eliminated due to low efficiency, uneven cleaning, poor results, etc.

Wet method is mainly the principle of the utility of the rotating cylinder, according to the unique electrical level discharge high voltage pulse counter in the water to produce a larger impact of liquid. Due to the different elasticity coefficient and vibration frequency of the casting itself, stainless steel casting surface adhesions and thus achieve the purpose of sand cleaning. For shallow holes, buried holes and other complex shape of stainless steel castings, spherical water glass casting inner wall cleaning effect is better. It is currently widely used in stainless steel castings in a series of casting surface cleaning methods.
