What Effect About The Cold Deformation of
    A, lost wax casting the effects of cold deformation:After annealing in products, mechanical processing of warping deformation of skew, etc.1, reason: because the casting residual stress, released in the process of bad.2, countermeasure: the...

What Effect About the Thermal Deformation
    When casting from the mold after demoulding, due to the different parts removed, unequal heat shrinkable lead to unequal casting size changes, the casting size.1, the reason: as the product of lost wax casting wall thickness is the same, the...

How to Accurately Inspect the Casting Def
    Lost wax casting at the time of production and processing of will appear different degrees of casting defects, if the casting defects when we should be how to test?Only under the condition of the casting defect inspection out so as to make o...

Accurate Insepct Casting Defects of Lost
    Lost wax casting for high pressure, vacuum casting, such as pump body, valve, pressure test should be done, to see if there are any holes casting defects.Test will have a certain pressure of the air (or water, oil, etc.) within the casting i...

Accurate Insepct Casting Defects of Lost
    X-ray inspectioncan be found lost wax casting casting internal defects, such as porosity, shrinkage cavity and crack, inclusion, etc.On important castings, such as defense industry with type I castings, typically after 100% of ray inspection...

Accurate Insepct Casting Defects of Lost
    Ultrasonic inspectioncan also be found lost wax casting, internal defects such as porosity, crack, inclusion, shrinkage, etc.Wall thickness of steel, using this method can detect the biggest (1000 mm) of a method.The working frequency of ult...

Wall Thickness Requirements of Precision
    Die casting wall thickness (often referred to as wall thickness) is a special significance in die casting technology factors, the wall thickness has close relationship with the whole process specification, such as filling time of calculation...

The structure of Precision Castings and
    A, the shape of the die casting structure requirements:1, eliminate internal side concave;2, avoid or reduce the core-pulling parts;3, avoid core cross;The reasonable structure of die casting can not only simplify the structure of the die ca...
