Introduction Materials [Solve Your Metal Processing Problems in One Shot!] Notice of the Flow from Application to Mold Production and Mass Production
"What are the functions of the parts required by the customer?" "Where is precision truly needed?" We will ask the customer's design representatives these questions, and our sales representatives will propose and consult on the machining characteristics and limits of the materials to be processed. We will make suggestions based on our predictions of potential issues, ensuring that we can provide parts that meet the necessary functions and precision at reasonable mold and product prices. Additionally, we will gather information necessary for the estimate, such as the total expected production quantity (guaranteed shots for the mold), before submitting the estimate.
