We would like to introduce NGK Fine Mold's "CAD/CAM Services." By utilizing high-end CAD systems such as NX (UG) and CARIA, along with complementary systems, we perform high-quality data processing for design and manufacturing. Some items can be processed in their three-dimensional data form, while others are converted to two-dimensional data for processing. All of these are part of a manufacturing system built as a result of pursuing QCD, and they are "flexible and adaptable." 【Supported Data】 ■ DXF, IGES, STEP, NX, CATIA, etc. *For more details, please refer to the PDF materials or feel free to contact us.

The technical document on the lesser-known resin molding die material "Beryllium Copper" explains the characteristics and applications of the copper alloy material "Beryllium Copper," which contributes to reducing manufacturing costs for mass-produced items, using easy-to-understand technical data and tables. It demonstrates cost advantages in the molding of automotive parts and engineering plastics! By shortening the molding cycle, it not only improves productivity but also contributes to reducing distortion in molded products and preventing sink marks. Furthermore, our company also offers hard coatings compatible with glass resin.

The material for molds, "Beryllium Copper," is a high-strength copper alloy with excellent thermal conductivity and superior wear resistance. Even in the molding of engineering plastics (engineering plastics) that require long cooling times, the high thermal conductivity enables a reduction in cycle time. Additionally, the common issue of poor cooling balance in large molds can be addressed, as it can be cooled without temperature variation, making deformation during molding less likely and leading to a reduction in defect rates. (There are examples of dimensional deformation being half compared to typical steel.) *It is also possible to improve the lifespan of copper with the dedicated coatings "DG Coat" and "TG Coat" for Beryllium Copper. **Voices from companies that have adopted this material:** ■Challenge: "We can't increase overtime due to work style reforms... We also lack manpower..." By switching to molds made with high thermal conductivity Beryllium Copper, we achieved high cycles! We succeeded in securing production volume without relying on outsourcing. ■Challenge: "Sales are slightly increasing... but profits are not rising..." Due to its higher wear resistance compared to steel and better cooling balance resulting in less deformation during molding, we achieved a reduction in defect rates! As a result, we succeeded in increasing the profits from the molds. *For more details, please download the PDF or feel free to contact us.

Our company, in collaboration with Okuma Corporation and NGK Insulators, has developed a technology to create high-hardness tool steel "SKD61" using metal additive manufacturing with "beryllium copper." ~Development Background~ In recent years, the use of engineering plastics has accelerated, many of which contain glass fibers, leading to accelerated wear of molds. If the mold has low durability, frequent mold changes and maintenance are necessary, resulting in high running costs and reduced mold operating rates. Therefore, by using metal additive manufacturing technology to shape high-hardness tool steel "SKD61" with "beryllium copper," which has high thermal conductivity and can shorten resin molding time, we aimed to improve productivity in the production of glass fiber reinforced plastics (GFRP) and other materials that faced challenges in wear and productivity. ~Expected Application Areas~ ■ Molding molds and parts (pins, inserts) for engineering plastics (e.g., GFRP and CFRP) ■ Chill vents and chiller parts for aluminum die casting ■ Molds and parts for hot stamping (hot pressing) ■ Continuous casting molds used in metal melting and casting *Detailed examples of metal additive manufacturing processing are available on our company website. Please contact us for more information.

NGK Fine Mold offers the 'DG Coat' and the new 'TG Coat', which are hard coatings used for beryllium copper materials. When molding engineering plastics, the material contains glass, which can cause the coating on the mold surface to peel off and the base material to wear more easily. By applying a coating to the surface of beryllium copper mold components, the lifespan is extended, reducing the frequency of maintenance during molding (such as mold cleaning and part replacement), contributing to lower running costs and improved equipment operating rates. 【Features】 ■ High hardness and strong adhesion to suppress wear and peeling in glass resin molding ■ Maintains high thermal conductivity, demonstrating high cycle performance comparable to the base material ■ Peeling and recoating are possible, allowing for repeated use 【Main Specifications】 Thin film, high hardness coating 'DG Coat' standard film thickness: approximately 8μm, hardness: approximately HV2000 'TG Coat' film thickness: approximately 1μm, hardness: approximately HV5000 * The TG Coat, with a film thickness of 1μm, is also applicable to high-precision parts, further improving wear resistance!
