These resources, combined with the expertise of our seasoned tooling technicians, enable us to craft impeccable molds.
We leave no room for compromise, meticulously inspecting both copper masters and steel components to ensure they align precisely with our drawings. Our monthly production output speaks volumes – crafting approximately 60 sets of molds monthly.
Goodtech goes beyond manufacturing; we help our customers streamline their product design, tooling, and manufacturing processes. Our commitment is to consistently meet customer standards with remarkable speed, economical investments, and more.
At Goodtech, our ultimate goal is to exceed customer expectations by delivering the highest levels of satisfaction, reducing production costs, and maximizing profitability.

 

At Goodtech, precision and organization define our tooling shop. 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.

Our mission at Goodtech is to consistently exceed customer expectations by delivering exceptional quality, cost-effectiveness, and profitability.

 

CNC machining plays a pivotal role in our plastic tooling fabrication process. We utilize this technology to precision-machine mold bases, extensive cavity and core areas, copper masters, and graphite masters. Our dedicated team of program engineers employs their expertise to streamline tool tracking and switching, thus enhancing machining efficiency while ensuring superior surface quality, dimensional precision, and geometrical accuracy.

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.

At Goodtech, we employ Coordinate Measuring Machines (CMM) to meticulously measure both copper masters and steel components, ensuring they align precisely with the specified design parameters. Every dimension is securely stored in our comprehensive database for meticulous tracking and in-depth analysis. Our stringent tolerance control extends to molds, guaranteeing that the precision of injection molded parts remains within the prescribed limits.

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.
