The Surface Finish Of  metal parts

The advantage of the   Surface Finishing of metal parts

1.1 Reflectivity and appearance     1.2 Tarnish resistance 1.3 Ability to bond to rubber (e.g., vulcanizing)      1.4 Hardness   1.5 Enhanced electrical conductivity    1.6Wear resistance  1.7 chemical resistance     1.8 electrical resistance1.9 Electrical conductivity

please select the best process according to your requirement of part.

See the note below:

Anodized :  the best material is pure aluminium 6061  ,made by cnc machining.but syx can anodize the die casting parts with aluminium adc12 material ,please see the the case  —anodizing die cast aluminium

heat treatment : T6 for aluminium 6061 ,and T1 for aluminium  die casting part

Impregnation:For the hermetic seal of the die casting part . prevent the water

Silk Screen Printing : Use for logo ,characters,   laser also ok ,but only for simple color
