Manufacturing & Assembling Services

Investment Casting

ABT produces custom designed castings for industrial use according to ASME, ASTM and
ISO standards. With advanced technology, rich experience, and mass production capability, we are
able to offer cost-effective castings of the highest quality.Investment Casting Process
Castings are produced by surrounding or investing an expendable pattern (Wax, Sodium Silicate,
Silica Sol, etc) with a refractory slurry coating. The pattern is removed through the use of heat prior
to filling the mold with liquid metal. ABT integrates product and mold design, mass production
and after-cast precision machining.

Advantages
Investment Castings have several advantages over other manufacturing processes.
Extensive range of raw materials
Complicated structure
Good surface finish
Tight tolerance

Cast Material
Carbon, Tool, Alloy, Stainless Steel, and non-ferrous steel such as Aluminum, Copper base, etc.

Forgings

ABT produces custom designed die castings for industrial use according to ASME, ASTM
and ISO standards. With advanced technology, rich experience, and mass production capability, we
are able to offer cost-effective castings of the highest quality.Forging Process
Forging is a manufacturing process in which metal is pressed, pounded or squeezed under great
pressure into high strength parts by the application of compressive force through the use of a power
hammer or machine press.

Advantages
Forging products have several advantages over other manufacturing processes.
Stronger and more ductile
Component repeatability
Consistent Quality
Long life

Material
Aluminum, Carbon, Alloy, Stainless Steels, Tool Steel, Titanium, Brass and Copper, etc.

Equipment
Crank Forging Press, Abrasive Forging Press, Hydraulic Forging press, Horizontal Forging Machine, etc.

Maximum Mass
50, 000 lbs

Dimensional Tolerance
