As part of our one-stop integrated manufacturing services, Impro offers sand casting for the production of high-precision, high-complexity, and mission-critical parts. Our resin sand casting processes include both highly automated machine molding and manual molding operations for medium-sized components to large and heavy castings. Our green sand casting process is highly automated for small to medium-sized components. Along with technical consulting on product design and alloy selection, we offer additional services, including heat treatment, casting machining, heat treatment, and surface treatment to supply high-end sand castings with complex geometries poured from high-grade materials.
We operate state-of-the-art facilities and leverage virtual prototyping software to visualize filling and solidification within the mold to optimize all aspects of tooling design and process conditions. With multiple molding lines, we have the capacity to accommodate parts as small as 1.2" in length x 0.4" in width x 0.2" in height or as large as 16' long x 13' wide x 10' high and weighing up to 22,000 lbs. We specialize in manufacturing castings from most types and grades of ductile iron, gray iron, and compacted graphite iron.
Our facility incorporates a state-of-the-art quality assurance department equipped with instruments such as spectrometers, metallurgical microscopes, cleanliness meters, and ultrasonic, radiographic, and magnetic particle inspection devices.
