Founded in 1967, R. L. Best manufactures large-tonnage hy-draulic presses that extrude large pieces of aluminum for construction-industry products, such as windows, doors and screened patio enclosures.
The company needed to design a container assembly that would maintain a specified temperature along the length of the aluminum piece that is inserted during extrusion. However, R.L. Best was having difficulty attaining the correct temperature throughout the container.
