Manufacturing Process Workflow
  In our high-speed machining center employing electrical discharge machining and other techniques, we manufacture high quality, precision metal molds designed by our skilled staff utilizing 3DCAD/CAM engineering. Concentrating on medium-sized molds in the 60-260 ton class, we endeavor to manufacture products designed and machined to the needs of our customers.  
metal mold design
CAD/CAM systems CAD/CAM systems
Product (part) drawings and data received from customers are processed into programming data for manufacturing, which is then sent to a machining center or another machine tool.
The multi-function 3-D CAD system displays and analyzes the shapes and characteristics of metal molds using wireframes, surfaces, and solid models to enable the design of more precise metal molds.
Press simulation 3DCADECAM
Mesh data is created from 3-D data created by the 3-D CAD/CAM systems, and then a press simulation is carried out prior to actual machining.
Creases, cracks, spring backs, and other issues are predicted, and then the data is sent back to the Design Section to plan for high-precision products during the first tryout.
Machining and finishing
Machining center Machining center
Data sent from 3-D CAD/CAM systems is used to automatically indicate manufacturing positions, tooling layout, manufacturing conditions, and other factors, and then profiling is carried out using a 5-axis double-column machining center or another machine.
Assembly, tryout and inspection
Assembly Assembly
The final-stage metal mold is assembled while checking the manufacturing precision of each part.
In the metal mold manufacturing process, this work requires the most experience.
tryout tryout
The completed metal mold is installed on a press, and then a trial press run is carried out.
Finally, a trial run is carried out in the presence of the customer using a mechanical press to guarantee precision for mass production.
Inspection Inspection
The trial product (panel) is inspected to determine the degree of completion of the metal mold. A 3-D measuring machine analyzes the precision of the product, and then the analysis data is sent back to the CAD/CAM system.
This data becomes a database for metal mold precision and next-generation development.
