About Us


LCS is a custom injection molder celebrating our 43rd  year of serving customers with the highest quality plastic parts.  We’re located in Waterville, Minnesota, approximately one hour south of the Minneapolis/St. Paul twin cities.  While we’re located in the heart of the mid-west manufacturing region, we’re able to provide regional style customer service nationwide.  Our formula for customer satisfaction assigns in-house project and account managers to provide the highest level of personalized customer service and fast turn-around times on quotes, prototypes, tooling, and production parts.



LCS carefully selects our vendors to ensure customers get the best possible pricing on a project from planning phase through production parts.  These relationships allow us to bring the highest levels of experience and skill to bear on your projects, and we’ve only built relationships with companies that we know have a customer first philosophy.  A partial list of our representatives and vendors includes:
