For nearly 40 years Perin Machining Company has been producing component parts to our customers with a zero reject part guarantee. We know that our customers can’t afford the consequences of bad parts, and realize that reject parts significantly raise the cost of production regardless of destination. For this reason, we utilize sophisticated statistical process control software along with internal system checks to hold an internal part per million reject rate to less than .001%. Continuous process improvement through waste eliminating Lean Six Sigma practices, and investment into new technologies is our tireless pursuit to ensure that our customer’s always receive the best quality for the best price.
