Sand Castings


 

Sand casting products are produced by pouring molten metal into sand mold cavity to form the products.


All-around and Flexible Sand Casting Capabilities

Impro is recognized by the industry for our capabilities of manufacturing high-end sand castings in different sizes with stringent requirements, complex geometries and high grade materials. This results in the production of components with slim wall, complex geometry and tight dimensional tolerance.

 

The state-of-the-art manufacturing equipment and advanced technology enable us to accommodate low  to high production volume and produce castings with a wide size range from 0.3kg to 20 tons. 

 

In addition, on top of normal grey iron and ductile iron, we can also use other high-grade raw materials to produce components in accordance with any special customer requirements such as heat-resistant ductile iron, low-temperature ductile iron, high-alloy ductile iron and compacted graphite Iron with our several large tonnages of medium frequency induction furnaces.

 

Our annual production capacity can exceed 33,000 tons.

 

Finished Product to Print

With dedicated in-house machining, heat treatment and surface treatment facilities, our integrated operations team will be able to deliver finished products efficiently to our customers. 

Highly Engineered Product for Diversified Markets
We manufacture sand casting products that are primarily sold to and installed inside high horsepower engines, construction equipment, recreational boats, agriculture equipment and medical equipment. Our star products include cylinder blocks and heads, hydraulic valve bodies, gear box parts, planet carrier parts and steering knuckles.
