• Mold Design

This is a multi-ring type mold developed with the aim of extending mold lifespan. We carefully selected the ring material, case material, number of rings, and fitting allowance to maximize the advantages of our in-house produced carbide, designing the die load capacity to be 1.4 times that of conventional molds. As a result, we have achieved excellent data with an average lifespan more than twice that of previous models. With a reasonable pricing structure that makes it easy to introduce, we have received high praise from our customers. 【Ideal for the following situations!】 ■ Want to extend mold lifespan ■ Improve mold quality ■ Capable of manufacturing products with high surface pressure *For more details, please download the PDF or contact us.
