Weld Repair

Heat Treating

The individual castings are heated to a desired range to soften their properties.

Materials Testing

The chemistry of every job/lot is checked in a spectrometer to ensure that all parts conform to their specification.
The physical/mechanical properties are determined by pulling a test bar coupon on a tensile test machine.
The machine measures the amount of force that is required to break the test bar.
These results are often cross examined through hardness (HRC) testing.

Non-Destructive Testing

Non-Destructive Testing - NDT - Use of test methods to examine an object,
material or system without impairing its future usefulness.

Liquid Penetrant Inspection

Liquid Penetrant Inspection is performed by applying a flourescent dye to the surface of a non-porus casting to detect cracks or other surface defects.

Magnetic Particle Inspection

Magnetic particle inspection is performed by magnetizing castings, and applying iron particles using a wet method, to detect surface and subsurface discontinuities.

Liquid Penetrant Inspection

Liquid Penetrant Inspection is performed by applying a flourescent dye to the surface of a non-porus casting to detect cracks or other surface defects.

Rapid Prototyping

AATC is a leading producer of Rapid Prototype aluminum and steel investment castings

AATC is here to meet all of your Rapid Prototyping needs. We are able to produce castings in as little as 4 weeks by converting patterns using the Stereolithography (SLA) Rapid Prototyping method and eliminating the delays required to manufacture traditional metal tooling. Geometry is virtually limitless and allows for such details as fins, pins, and complex, integrally cast cores. This process is extensively used by design engineers in the development of new products, allowing designers to go directly from a CAD file to a fully functional aluminum and/or steel casting. The method is flexible and allows the use of different RP patterns from a variety of processes.

Traditional Lost-wax Process

The traditional lost-wax process involves the manufacture of a metal tool (die) which typically takes 6-14 weeks depending on part complexity.

Wax is then injected into the die to produce the wax pattern which is subsequently gated and coated with ceramic shell to build a ceramic mold.

The wax pattern is melted out (hence lost wax) and metal is then poured into the empty mold resulting in the casting.

Finished Casting in 10-18 weeks

Rapid Prototype Process

The rapid prototype pattern is built from a CAD design and substituted for the wax pattern. This takes from 1-2 weeks.

The RP pattern is subsequently gated and coated with shell material. After shelling the RP pattern is eliminated from the mold using special procedures.

The remaining production stages follow the traditional lost wax process, producing a finished casting with the rapid prototype pattern.

Finished Casting in 4-5 weeks
