Draft Angles in Die Castings

Kinetic Die Casting Company discusses “Draft Angle in Die Castings” – “what is draft angle in an aluminum metal box casting?” or “why do I need a draft angle on my aluminum die casting box part?” The mechanical reply is, all aluminum die castings need a draft angle on the walls of die cast box parts perpendicular to the parting plane or parallel to the slide interfaces. Because I have been selling die cast parts for over 20 years, I find easy answers and give simple calculations for my clients. What does that have to do with the usual engineer (any engineer other than in tooling or mechanical) or professional buyer?

Most people do not have the need to worry about how things are made; only what is made, and will it be what is essential. “Have you ever observed on a cupcake the bottom diameter is smaller than the top diameter?” or “Have you noted that a cake pan has sides that slope in toward the middle of the pan?” That would be an extreme case of a draft angle. Aluminum die castings would stick inside the die casting tool, molds, or die casting die if there was not enough draft angle in the tool and part. The usual draft angle for an aluminum die casting part is two degrees per side. The calculation for that is easy if a anyone is acquainted with die casting production part design.

Imagine an enclosure (or Aluminum Box) lying on a counter with the open side up. The aluminum box is 2″ deep inside with the height and width 4″ each way on outside. The walls of the box are 0.10″ in width. Due to the wall’s thickness, a few things are obvious to a part designer regarding this seemingly simple box:

  • The general height of the box is 2.10″ tall.
  • The inside of the box at the top of the opening is 3.80″ x 3.80″.
    A 2 degree draft angle will alter the dimensions in the following on the interior and exterior and should be regarded if something needs to fit inside the box or outside the box:

  • The top inside dimension of the box will be 3.80″ and the bottom inside will be 3.664″
  • The top outside dimension of the box will be 4.00″ and the bottom outside will be 3.864″
    If the box was intended for the interior of 4″ x 4″ at the bottom: box:

  • The top inside box dimension needs to be 4.136″
  • The outside top box dimension will be 4.336″.

    The Advantages of Die Casting Tooling

    The Advantages of Die Casting Tooling. Die casting tooling is recognized in the metalworking industry as a well-organized and economical procedure that is utilized to generate plain to multifaceted shapes that are being exploited by a variety of sectors. The power and other sort of the production of the die casting tooling depend a lot on the alloys which were used in the technique.

    The most frequently utilized alloys in the die casting tooling include zinc, magnesium, aluminium, copper, lead and tin. Zinc is recognized as the alloy that is simplest to cast. This has high ductility and can effortlessly be plated. This is also inexpensive when it comes to little parts. Magnesium, on the other hand, is the easiest to machine. This is also the lightest element utilized for this function. Aluminium is also lightweight. This encloses fine mechanical properties. This also has high thermal as well as electrical conductivity. Copper can be reliable to come with the finest dimensional constancy– also holding the highest mechanical properties. Lead and tin are recognized for their high density.

    Manufacturers use die casting tooling for the subsequent reimbursement that this can offer.

    1. This allows the manufacture of parts that are dimensionally stable as well as sturdy. These parts are also heat resistant.

    2. The construction can be done in high volumes at a faster speed. Through such, a high number of outputs can be attained with shapes that are multifaceted with closer tolerances.

    3. The finishing can be done according to what reason the parts would be utilized. It can either be textured or smooth surfaces. These types can then be plated and finished with smaller surface preparation.

    Aluminum Sand Casting Parts May Be Better

    Aluminum Sand Casting Parts May Be Better. Several Requests For Quotes (RFQs) for aluminum part prices come to Kinetic Die Casting and it is obvious that the requester does not understand the difference between aluminum sand casting parts and aluminum die casting parts. Today, we will discuss the pricing difference between sand casting and die casting of aluminum parts.

    2,000 Aluminum Parts Casting Decision
    If your product is limited to less than 2,000 aluminum parts in the entire product life cycle or stated differently you will want less than 2,000 aluminum parts in your product life cycle and never need more parts, sometimes a part produced by the aluminum sand casting is a better choice for you.

    Here are my aluminum part price calculations:

    Aluminum Sand Casting Parts:
    Typical Tooling Cost: $500 – $2500
    Typical Part Cost: $13 – $15 each (machined)
    So using $500 tooling price (lowest typical) and $13 for part price:

    Cost for 500 parts: $ 7,500
    Cost for 1000 parts: $13,500
    Cost for 2000 parts: $26,500

    Aluminum Die Casting Parts
    Typical Tooling Cost: $10,000 – $12,000
    Typical Part Cost: $2.50 – $3.50 each (machined)
    So using $10,000 die casting tooling price (lowest typical) and $2.50 for part price.

    Cost for 500 parts: $11,250 ($3,750 more expensive)
    Cost for 1000 parts: $12,500 ($1,000 less expensive)
    Cost for 2000 parts: $15,000 ($11,500 less expensive)


    As you can see, the cost is equal or less for an aluminum part as a sand cast part, if you will buy less than 2,000 parts. If you feel your product life is more than 2,000 parts, you should consider buying aluminum die casting parts. If your product life is greater than 5,000 parts your savings are so significant it is embarrassing. Contact Kinetic Die Casting Company 800-2524-8083 (sales@kineticdc.com) if you feel you are paying to much for your aluminum castings.

    Die Casting Tooling

    Die Casting Tooling. The manufacturing method known as die casting is a flexible method of producing somewhat miniature metal parts in bulk orders. Metal parts are completed by the powerful insertion of molten metal alloy under high pressure into a steel die, letting it sit there until it solidifies. The metal alloys that are utilized in this procedure are aluminum, zinc, magnesium, copper, tin, and lead.

    The die casting tooling is completed of steel. This is owing to the fact that a die or mold created out of cast iron would not tolerate the high pressures necessary in this approach. There are at least two parts in the die casting tooling which is the ejector die half that directs the molten metal into the cavity and the fixed die half which has a hole where the molten metal can load the die. The die casting tooling also consists of openings, locking pins, and ejector pins. The openings are where the molten metal is refrigerated and where the castings are oiled. The locking pins are utilized to secure the two halves of the die casting tooling. And the ejector pins are utilized to effortlessly remove the casting. When the die is closed, the ejector and fixed die halves locked together due to the hydraulic pressure of the die.

    The die casting procedure seems to be the fastest, cheapest, easiest and most efficient way of manufacturing metal parts without cutting down on the product’s quality. It is absolutely a excellent thing that the idea of die casting was ever invented.

    Kinetic Die Casting utilizes die casting to manufacture parts like aluminum car parts, airplane parts, lighting parts and much, much more. If you would like to request a quote, please visit our website:Die Casting quote
