What will the cost be?

There are two factors that affect unit cost — low production and full production. Let’s start with low production, which is the best option for when you need 1- 5 castings and have no tooling. Or, you may have an old casting you would like to reproduce, such as an antique car part, a decorative art object, a historic architectural element, etc. These pieces will be priced at the higher end. At Marlborough Foundry, we do our best to estimate the time to produce such parts, but you never make enough of them to streamline the process.  See also Rapid Prototype, Architectural, and Ornamental in our APPLICATIONS section.

The other option is full production, which is where the economies of scale come into play. The more often it is made and the larger the quantities, the more economical the process becomes.  Our sales department knows this and will keep the pencil sharp in the quotation process.

How long will it take?

Tooling will take approximately 3-5 weeks depending on the complexity of the part. A sample casting is then made and sent to you for approval of the dimensions and surface finish.  After we secure your approval, production can begin. Delivery is usually 4-6 weeks but can be shortened if necessary.

Who owns the tooling?

Your company owns the tooling but it can be stored here at Marlborough Foundry free of charge for as long as the account is active. However, the proprietary gating system may be removed upon return of the tooling.

What is the best casting process for my product?

Depending upon expected production, tolerances, and casting size, we will recommend the best casting process for your product.  You can read more about each of the casting processes that we perform here at Marlborough Foundry and find a chart of their cast tolerances under Sand Casting or Permanent Mold Casting in our PROCESSES section.

Which is the best aluminum alloy for my application?

The diverse aluminum alloys that we pour all have their own unique properties.  Some alloys will provide you with the very best of strength while at the same time are lacking in the dimensional stability of other alloys.  Some seem to offer great strength, stability and finish, but they have less than desirable casting characteristics, thus making their properties unattainable for certain designs.  You can read more about this subject on the Alloy Selection page under TECHNICAL.

What files can you use to produce a pattern?

We still produce some patterns and permanent molds from paper drawings and sketches.  But, we prefer to have 3D CAD files for dimensional accuracy and cost considerations.  The most popular 3D file is IGS format, although we can use or convert most any file that you have.
