[Press Processing Example] Complete Pressing / SUS Thick Plate / Multiple Hole Processing
EGR end plate
Challenging processing that far exceeds the limits of pressing! By replacing the machining method that created 34 holes with pressing processing, we achieved significant cost reduction!
This is a product made of stainless steel with a diameter of 80mm and a thickness of 3mm, featuring 34 holes with a diameter of 10.2mm. In conventional press processing, it is said that a pitch of twice the plate thickness is required between holes, meaning that for a plate thickness of 3mm, a hole pitch of 6mm is necessary for the press processing to be feasible. However, the hole pitch of this product is a minimum of 0.95mm, which is less than one-sixth of the value considered the limit for press processing, so the customer had no choice but to handle all the holes through machining. Naturally, this resulted in increased production time and costs, causing significant difficulties for the customer. Upon consulting with us, we began developing a press processing method. After various twists and turns, we succeeded in converting the entire process to press processing (excluding the finishing burr removal barrel), achieving significant cost reductions, which greatly pleased the customer.
