Total service for plastic molds

Please feel free to consult us about anything related to plastic molds. In recent years, we have been responding to the high demand for short delivery times and low-cost plastic molds, cassette-type molds for resin molds, simple molds, prototype molds, and small lot molds by introducing the world's fastest mold design software, TOPMold, and utilizing our original cassette-type molds, aiming to deliver "the optimal products in the fastest time." With 60 years of experience centered around plastic molds, we are committed to leveraging the technology and know-how accumulated over the years, along with the latest equipment and cutting-edge plastic mold design software/CAD/CAM, while making the most of the strengths of both old and new. Although our company is not large, we pride ourselves on our "sincere and meticulous response" to even the smallest requests from our customers. At Sannomiya Seisakusho, we also focus on thorough data management and security measures, considering the handling of many new and developed products. If you are considering products made of plastic, elastomers, etc. (resin) or injection molding molds, we would be grateful if you could consult us about anything.
