Like Permanent Mold, all sand casting patterns are not created equal. There are many kinds of sand casting patterns, ranging from a simple wood pattern, which wears quicker but can be good for prototyping, to aluminum machined patterns that create a better dimensional accuracy and have a longer life cycle. At LeClaire Manufacturing we listen to our customer’s needs and help them make informed decisions regarding what they need. We have a unique advantage of understanding the intricacies of building a sand casting pattern itself and also an understanding of the intricacies of the casting that the pattern produces. This combined knowledge give LeClaire Manufacturing and advantage that enable us to make slight adjustments in the design phase of the mold that will create a better casting when we move to production.
