At Baoyuan, our tooling shop is defined by precision and organization. We offer a comprehensive range of services, including CNC machining, EDM, wire cutting, cooling line drilling, polishing, and meticulous mold fitting and assembly.

Each component of our molds, from plates to side actions, sliders, and control boxes, is marked with a unique identifier for seamless tracking from machining to assembly. Moreover, our commitment to accuracy extends to every copper and graphite master, which undergo CMM measurements and are recorded in our ERP system.

In scenarios involving small, narrow areas or the processing of hardened steel, Electrical Discharge Machining (EDM) emerges as a highly efficient method. The fundamental principle of EDM involves the controlled movement of the copper master toward the steel block, creating a minuscule gap (typically ranging from 0.08mm to 0.25mm). During this process, an electrical breakdown occurs, triggering electrical discharge that meticulously burns away the surface of the steel. A cooling liquid efficiently carries away the resulting fine powder of burnt steel, effectively removing the surface material.

The fitting, assembly, and polishing stages demand the expertise of skilled technicians who work diligently and attentively. In addition to creating new molds, we place a strong emphasis on regular mold maintenance. Typically, every 100,000 shots, we remove the molds for thorough cleaning and meticulous repair of critical components, including mating surfaces, ejecting systems, cooling lines, venting channels, sliders, and hot runner systems. This proactive approach ensures that only healthy and robust molds are in use, guaranteeing consistent quality and operational efficiency.
