Casting Tolerances

 Casting Tolerances Precise Cast

The specifications below should be used as general guidelines only. We can meet especially tight or critical tolerances. Please contact us to discuss your specific application.


Master Pattern:

SLA: ±.005″ distances less than 5″; ±.0015″ per inch for each additional inch
Machined Patterns: ±.003″ distances less than 5″; ±.001″ per inch for each additional inch

Casting Dimensions (deviation from master pattern):
XY axis (length/width):±.005″ distances ≤1″; ±.002″ per inch for each additional inch
Z axis (height):Up to +.015″ distances ≤ 1″; ±.002″ per inch for each inch thereafter
Cores/Slides (inserts):±.015″ distances ≤1″; ±.002 “per inch for each inch thereafter
Location tolerance for mold inserts (cores – slides):±.015 or ±.5°

Maximum Part Size:
Distance in X or Y axis (length/width): 34″
Distance in Z axis (height): 20″
Maximum part mass: 30lb

Geometry:
Wall thickness of .020″ possible depending on geometry
Zero draft required on features
Undercuts possible
Multiple cores/slides
Geometry that is typically associated with investment casting can be produced

Mechanical Properties:
Tensile, Yield, Elongation – per the specified commercial and military specifications.
