WHY US

@ We are very professional for investment castings making.
@ Technology from Taiwan. Casting Parts with very good consistence and beautiful finish.
@ Spectrometer Inspecting for each material batch to ensure correct material to be used.
@ Annealing Treatment to ensure consistent Micro-structure and not deform for ever.
@ If need, some parts will go into Shape Correcting process to ensure consistent shape, dimensions.

Other Statements:  Why shape/dimension Rectification is necessary for castings

Not like machined parts, investment castings will deform in varying degree during production.
Usually, it is the biggest problem for this kinds of parts.

Several main reasons as below:-
@  Wax mold deformation (one main reason; wax is SOFT)
@  When casting process, during cooling down, SHRINKAGE will lead to deformation in different position/direction especially for those Asymmetrical part.
@  Part surface Shot Blasting also will lead deformation a little bit.
@  After Annealing Heat Treatment, Deformation also might happen after this process
