How Tolerances Affect Product Manufacturing Costs.

Tolerances affect product design, manufacturing, and quality control, making them critical to the successful performance of an end product. 

Customers sometimes ask us why a part is so expensive in prototyping or production. Many times designers don’t realize that extending overall tolerances by one more decimal point can increase the cost of part by a factor of two or three. 

Therefore an extra decimal of overall tolerance which is not specified for a technical reason, can cost you thousands of dollars over the life of a manufactured part. That is because tighter tolerances require greater care in machining and inspecting in order to ensure accuracy. 

Progressive Machine shops like CIMTech Manufacturing gets involved with our customers during earlier stages of product development, understanding customer’s functionality requirements, assisting them to optimize their part designs to lower cost of manufacturing. 

Choosing proper tolerances can help you to ensure product quality, ease of manufacturing, and time to market. If you don’t know or are unsure about what tolerances are right for your project don’t hesitate to reach out to us.

CIMtech Mfg will walk you through the decision points helping you identify what is mission critical and determine the proper tolerances for your parts.
