Re: Car Parts Foundry price quote

Dear Mr. Simpson,

Thank you for your inquiry regarding the cost of producing the valve bodies, valve bonnets, and pistons you require.

In order to quote the exact cost of these pieces, I will need to have accurate renderings of them. The designers in our shop need these to determine the size and location of the risers for each casting. Our QAD team would be happy to run the standard stress and endurance tests on the finished pieces at no extra charge. The riser is an extra section of the pattern that keeps pressure on the molten metal and prevents air bubbles from forming in the metal at the time of its pouring. Therefore, the design and placement of the riser plays an essential role in determining the strength and safety of the finished piece. The excess metal is later removed from the casting in the grinding-and-cleaning process.

As soon as I receive the renderings from you, I will contact you to discuss the total cost of your order. Substantial discounts apply to orders of one thousand pieces or more for our premium product lines, such as our TUFF-STUFF product line. However, these discounts only apply to our mid-market lines, such as Valve Components products, at orders of two thousand or more pieces. We have a wide variety of other car parts and casings, as well.

Thank you for your interest in our company.
