Pressure Safety Lock

pressure-cooker-slideOur customer came to EJ Ajax because they had problems holding tolerances on an aluminum bracket with a square notch. It is a safety component on a consumer small appliance, so it has to be right. We designed a strengthening gusset that lets the part work-harden, while maintaining dimensional integrity within .5°.

When the customer moved manufacturing to China, they retooled everything except our part. The offshore operation couldn’t meet the functional requirements. As a result, we didn’t lose a client—we gained a market. Our volume has increased from 50,000 parts a year for the U.S. market to nearly a million parts a year globally.
