JBRplas has expanded its in-house mold manufacturing capabilities with the addition of a DR450H electrical discharge machining (EDM) machine. The machine arrived at our facility on October 12, 2026, completed installation and commissioning on October 16, and is now in production.
This investment supports JBRplas's continued development of precision injection mold manufacturing capabilities, helping us manage more of the mold-making process in-house and support customers from mold design and tooling through injection molding and finished plastic parts production.
Electrical discharge machining is an important process in injection mold manufacturing, particularly when machining features that are difficult to produce using conventional cutting tools.
Depending on the mold design and electrode configuration, EDM can be used to produce deep ribs, narrow slots, intricate cavities, sharp internal corners, and other complex geometries in hardened or conductive mold steels.
For plastic injection molds, these features can affect part geometry, mold functionality, surface quality, and the overall manufacturability of the tool.
By adding the DR450H EDM machine to our manufacturing equipment, JBRplas aims to strengthen its in-house machining resources and provide better support for molds with complex cavity and core features.
Injection mold manufacturing often involves multiple machining processes, including CNC milling, EDM, fitting, assembly, and mold trials. Each process contributes to the final quality and performance of the mold.
EDM is particularly useful for mold features that require material removal through controlled electrical discharges rather than direct mechanical cutting. Its application depends on the workpiece material, electrode design, machining parameters, and required finish.
With the DR450H now in operation, JBRplas can incorporate this additional equipment into its mold-making workflow. The objective is to improve process coordination, strengthen control over critical machining operations, and support consistent mold quality.
Actual machining capability and achievable tolerances remain dependent on the mold design, material, feature geometry, and process requirements.
JBRplas is a one-stop plastic mold and injection molding manufacturer in Shenzhen, China. Our services cover mold design, mold manufacturing, plastic injection molding, surface finishing, assembly, and packaging.
For OEM customers, coordinating mold manufacturing and production within one supplier can simplify communication, improve coordination between tooling and molding teams, and help identify manufacturing issues before mass production.
The addition of the DR450H EDM machine is part of our ongoing investment in manufacturing resources that support this integrated approach.
Whether a project involves a new injection mold, a complex plastic housing, or a custom-molded component for industrial or consumer applications, our team evaluates the product design, tooling requirements, material selection, and production needs to determine an appropriate manufacturing process.
At JBRplas, equipment investment is driven by the practical requirements of mold manufacturing and plastic parts production. We continue to develop our manufacturing resources to support complex tooling projects, improve coordination across production stages, and serve customers seeking a long-term manufacturing partner.
The DR450H EDM machine completed commissioning on October 16, 2026, and has entered production at our Shenzhen facility.
