Investment Casting Drawing Details
From concept to finished drawing, IPCL’s engineers are ready to assist customers at all stages of casting design.
They can provide suggestions and guidance regarding
tolerances and design details, alloy selection and even
approximate pricing. Their aim is to help customers
select the best manufacturing process, whether or not
it is investment casting. If you decide to order an
investment casting, it is important to make sure that
all the details needed to make a fair and accurate
quote are included on the drawing. Doing so enables
us to quote in a timely manner. It also shortens lead
times and reduces confusion, manufacturing problems
and the potential for changes and price increases after
you place your order
At a minimum, the following information should be included on the drawing or in your request for quote. Please call us if you have any questions about this list.
