【Processing Method】 Press Processing Press processing is a method of machining that uses molds to punch materials, making it a highly efficient processing technique suitable for mass production. By creating a mold once, the same shape can be repeatedly produced with high precision in a short time, allowing for both cost reduction and quality stability. This method is particularly optimal for mass production projects, especially for products like flange gaskets that have many bolt holes, as it ensures uniformity in hole positioning and dimensional accuracy. 【Q&A】 Q1. Is it possible to process large-diameter flanges? A. We have a track record of producing large-diameter gaskets and can respond with optimal processing according to size. Q2. Can you handle products with many holes? A. We can ensure stable quality with uniform hole placement through press processing. Q3. Is mass production possible? A. Stable supply is possible through mass production processing using molds. Q4. Can you produce using other materials? A. We accommodate a wide range of materials, including rubber, resin, and various sheet materials.
