Description

Precision castings include:investment casting,ceramic mold casting,metal casting,pressure casting,lost foam casting,which play a vital role in the industrial development.Therefore,it becomes very important to keep the good quality of precision castings.And the right methods to clean the surface of precision castings are also important.Here's an overview of some of the more common methods.


The dry cleaning


The dry cleanup mainly includes friction cleanup and shot peening,cleaning,blasting compressed air as the motive force,the steel shot is ejected at a faster rate to the workpiece surface,Precision Casting clear debris on the castings.Shot peening flexibility,is an effective complement to shot blasting,shot blasting,shot blasting machine,spraying steel shot,and clean up the casting surface impurities.


As the clean-up of major mechanical surface debris clean-up of the domestic stainless steel precision casting products,shot blasting machine.And technology development as shot blasting technology,in addition to stainless steel precision casting castings,also applied to the surface of the metal parts reinforced steels in addition to the field of scales the rust well as shot blasting molding,etc..


Water clean-up


The role of the electric pressure housing clean,its basic principle is that the electro-hydraulic hammer effect, the use of high-voltage pulse discharge gas passed water special electrode discharge to generate a lot of fluid power.Debris and metal precision casting casting surface vibration frequency,so the purpose of clear sand.For complex shaped castings have a good clean-up role.


Hydroblasting refers to the use of high-pressure pumps to enter the high-pressure water,high pressure jet,fired the gun nozzle to form the casting surface sand.A method is mainly applied to the surface of the larger pieces of cast iron to clear sand and clear core.


Clear water sand


Precision Casting products of a certain temperature with sand hanging into the pool, the water heat of vaporization of the hot sand and the sand core,with the vaporization of water and steam continue to be heated,the pressure increasing,the sand and the sand core from the casting surface and the lumen fall out,so as to achieve the purpose of the fettling.


No matter which method is used to clean up,the goal is to make precision casting products of guaranteed quality,customer satisfaction.
