Keystone’s main background is manufacturing. We make the machines that make machinery. We design and build equipment that holds up to decades of service. We have built custom drills, lathes, mills and grinders. Keystone equipment is typically used where an “off the shelf” system is not available. We also integrate custom loading and unloading or part inspection systems into standard equipment. We also provide on site troubleshooting and repair service on other brands of equipment. When you need a custom manufacturing machine whether it’s for plastic, metal or any other material, call Keystone.
