Die Casting Aluminum Information
Die Casting, A Brief Description:
Diecasting is a manufacturing process in which molten metal is injected, under pressure,
into a hardened steel die or also called mold. Dies are often water-cooled. Dies are then opened,
and the die castings are ejected (many times thousands of parts each day, sometimes only a few
hundred). Once the tooling is paid for, die casting is a very inexpensive aluminum part manufacturing process.

C-D Die Casting Chatsworth California
Sometime around the year 2003 or 2004 C-D Die Casting Company in Chatsworth California, closed their doors for the final time. C and D Die Casting Company had been around for many years prior to that time. C and D Die Casting Company had locations in Arizona and Mexico. The plant location in Mexico closed down for production a few years prior to Arizona closing and Arizona closed a few years before the California location.
C and D Die Casting Company specialized in small parts with their self made die casting machines. They had a few larger machines but the larger part of their business was on the small 400 ton die casting machines. Their self made 400 ton die casting machine had the appearance of a 100 ton die casting machine by most machine manufacturer standards.

Steel Parts verses Aluminum Parts
Aluminum Die Casting Parts
Aluminum parts that are die cast are less expensive than steel. Steel parts weigh three times (3x) more than aluminum parts. So, the cost of materials by weight of the part is less. The cost to ship aluminum die casting parts is less than steel parts because of the weight differences. Fabricating a steel part is more labor intensive and time consuming than a die casting aluminum part. The die casting aluminum part can be used as is but a welded steel part will need a paint process to make them acceptable.
Aluminum Die Casting Part Design
Aluminum die casting parts can be designed to be very strong. Some aluminum die casting parts have strengthening ribs and gusset radii to increase the strength of the aluminum part. Aluminum die casting parts can be designed to be as strong, or stronger than a steel part.
Aluminum Die Casting Part Production
Aluminum die casting parts can be produced at the rate of over 1,000 parts in a day of die casting manufacturing production. The steel fabrication of parts can take as much as 10 days to make 1,000 parts. The cost per part as an aluminum die casting part is less than $3.00. A comparable steel part will cost about $5.00 each steel part and the wait time is ten times (10x) longer than an aluminum part.

Tooling for Die Casting
Tooling for Die Casting is also known as die casting tooling and die casting molds. The tooling for die casting is constructed from steel and is hardened to 40 plus Rockwell. The steel is cut using mill cutters and using an EDM (Electronic Discharge Machining) process. The die casting mold usually takes more than six weeks to create, many times it may take ten or more for larger or more complex die casting molds or tools.
The area of the die cast tooling that creates the form of the part casting (part) is called the die cavity. The die cavity has the inverse shape of the part casting, like a muffin pan. The cavity is usually inside the “cavity insert” a square block of steel that will fit inside a mold base. There are two inserts for each tool, one for the “hot side” and one for the “ejector side”. These inserts are typically the same size in height and width and can vary in depth, depending on the part cavity depth.
The inserts are mounted in a “Die Mold Base” that is much larger than the set of inserts. The hot side of the moldbase has a hole where the molten metal is injected into the die through a cylinder (shot cylinder) pushed with a shot piston. The ejector side of the moldbase has an ejector plate with pins, known as ejector pins, these ejector pins push the completed part casting out of the cavity.
The cost of the die casting tooling is the responsibility of the customer. Sometimes tooling inserts are sold to a customer to save the cost of making die casting tooling. The cost of the moldbase is born by the die casting company.
