Progressive molding of carbon steel instroduction
Progressive molding of carbon steel
Progressive die stamping of hot-rolled and cold-rolled steel is a die-based cutting and forming process that includes a series of stamping stations. These stations simultaneously operate the steel plate on the coiled strip. Progressive die ("Die") is a metal processing equipment designed and manufactured to transform a flat strip of metal raw material into a complete part that meets printing specifications.
Metal stamping of various size parts
In Qingdao Yonglihao, we can produce high-precision, highly detailed customized hot-rolled and cold-rolled precision metal stamping parts and components that meet all customer design specifications.
Using our production capacity of up to 440 tons of presses and our in-house precision stamping dies and tools, we can manufacture parts with a thickness of only 0.002 inches while maintaining tolerances that often exceed industry standards. We provide services to customers in all industries, and provide short- and medium-term metal stamping parts for parts and parts of various shapes and sizes.
Custom-made stamping tools and dies
Qingdao Yonglihao's stamping dies are custom tools that can be used with stamping machines to cut or shape steel plates into desired shapes. Most stamping tools are custom manufactured, usually made of tool steel, which is sufficient to cut most other types of metals while maintaining the tolerances required for stamping parts.
