Product Description
We have two types of investment cast processes. They are the shell process (Colloidal Silica process) and the water glass process.
A wide range of alloys is available for both processes. They include carbon steels, low alloy steels, stainless steels, tool steels and copper based alloys.
Please check the technical specification sheet for materials available.
Shell investment cast parts can range from a weight of just a few ounces to approximately 80 pounds. Water glass castings may range in weight from several ounces to approximately 200 pounds.
First article layouts and spectrometer material certifications are provided with all first article samples.
A variety of secondary operations can be performed on both types of investment castings. They include heat treatment, machining, plating, painting, polishing and buffing, assembly services and even custom packaging.
Plastic bag, carton, pallet or ploy wood box
All other processes available: Sand casting, die casting, permanent mold casting, forging, stamping, welding, extrusion, CNC machining and assembling
Materials available: Cast iron, carbon steel, alloy steel, stainless steel, aluminum, brass, and zinc alloy.
Surface treatments: Painting, epoxy powder coating, anodizing, galvanizing and polishing
Weight: 0.1 to 10, 000kg
Used in metallurgy, automobile, aero, chemical, ship hardware, and other industries.
We need our customer bear the tooling cost to make OEM samples. Such cost can be deducted from future order.
