Basic Aluminum Casting Co.

For over half a century The Basic Aluminum Casting Company has been a privately held, financially solid die casting company with a professional integrity matched by few in today’s industry.diecasting

At The Basic Aluminum Casting Company, we bring quality die casting with delivery and pricing achieved through a sound business organization. Centrally located in Cleveland, Ohio, we’re easily accessible across the Midwest and the entire United States. Occupying over 55,000 square feet at our plant, Basic has serves the transportation and general manufacturing industries and beyond! The Basic Aluminum Casting Company can be best described as an engineering company with one simple trait – creating die cast products  from listening and understanding our customer’s needs.  A strong commitment to that and a focus on quality has enabled us to continue to be one of the best and oldest names in the industry.

The minimum thickness of die-cast walls varies inversely with the melting point of the material. It also depends on the fluidity of the metal and upon the size and shape of the casting. The possibility of casting thin sections of more than average strength is a distinct advantage in die casting, aside from the commercial feature of saving material.

As to limitations of thickness of section, the only general rule for die castings is this: If the section is too heavy, exceeding 1″ or so, the structural uniformity of the section suffers. There is a rather a steep chilling gradient from the outside to the center of the casting, thus causing a considerable variation in grain size and mechanical strength. Also, the danger of internal porosity increases with the thickness of the section. Unduly heavy sections should be avoided; and when mechanical strength or stiffness must be high, thinner sections with judiciously placed strenthening and stiffening ribs should be used instead.

The average grain size of the die cast structures is on the order of .0005″, which is compared with grain size of .020″-.050″ for permanent-mold castings and from .050″ and up for sand castings. Because of the fine gain structure obtained by the rapid chilling of the metal in the die, die castings have an “as-cast” strength that is greater than the castings produced by any other method.

Keeping sections thinner to allow for this rapid cooling only helps in creating grain structure that is complementary to die cast strength.
