NGKファインモールド List of Products and Services

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! Why not give it a try? * For more details, please refer to the PDF document 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.

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.

The "beryllium copper alloy" provided by NGK Fine Mold is a copper alloy material commonly used in resin molding die materials, including general-purpose plastics and engineering plastics. ▼ What are the reasons? ☑ Excellent thermal absorption rate shortens the cooling process of molding ⇒ Achieves increased productivity! ☑ Uniform cooling eliminates deformation and sticking during molding ⇒ Contributes to quality stabilization! With thermal conductivity 3 to 7 times that of steel, measurements of the temperature change in one cycle of the mold showed a reduction in heating time by 10 seconds and cooling time by 30 seconds. We have successfully achieved a significant cut in molding cycle time. In addition to providing it in molds, we also offer it in round bars and blocks. *For more details, please refer to the PDF document or feel free to contact us.

In the plastic molding process, "high cycle" refers to rapidly cooling to the demolding temperature. Our company offers a resin molding die material, "Beryllium copper alloy round bars and blocks for high cycle molding," which reduces the molding cycle time from 90 seconds to 50 seconds. By using beryllium copper cooling inserts and pins in heat-storing areas such as thick sections, ribs, and tips, we eliminate temperature differences. Additionally, it has high thermal uniformity, particularly preventing twisting deformation in molded products like flat plates and long items. **Features of Beryllium Copper** - Reduces distortion and prevents sink marks in molded products - Improved lifespan with hard coatings for beryllium copper, "DG Coat" and "TG Coat" - Thermal analysis using CAE *For more details, please refer to the PDF document or feel free to contact us.*
