• Graphite Molds for 3D Mobile Phone Glass:

In recent years, the demand for 3D curved glass in smartphones has surged, driven by premium design trends in flagship devices. Dongguan Dongmei Graphite Industrial Co., Ltd. successfully delivered a custom 3D graphite hot bending mold solution for a major Chinese smartphone manufacturer based in Shenzhen. The client required a mold capable of producing ultra-thin, high-precision 3D glass covers with minimal surface defects and consistent dimensional accuracy across thousands of units. Using SGL Carbon’s R8710 premium graphite material—known for its ultra-fine particle size (3μm), mirror-like surface finish, and exceptional thermal stability—we engineered a mold that achieved a surface roughness of Ra < 0.1μm after EDM processing. The mold demonstrated zero deformation during repeated heating cycles up to 650°C, ensuring long-term reliability. Additionally, the low ash content (max 0.02%) prevented contamination during the high-temperature forming process, which is critical for maintaining optical clarity in the final product. The client reported a 40% reduction in mold replacement frequency and a 30% increase in production yield compared to previous copper-based molds. This project not only solidified Dongmei’s reputation as a technical leader but also showcased how advanced graphite materials can revolutionize mobile phone manufacturing efficiency and quality.

• High-Performance Graphite Electrodes:

A leading automotive parts manufacturer in Guangzhou faced challenges in producing precision interior trim molds using traditional copper electrodes due to excessive wear, high processing time, and frequent rework. Dongmei stepped in with a customized solution using SGL Carbon’s R8650 graphite electrode material—ideal for high-demand applications requiring excellent mechanical strength and low discharge loss. We designed and machined a complex multi-cavity electrode for a dashboard insert mold, leveraging our in-house fleet of 18 specialized graphite processing machines and advanced CNC precision machining. The resulting electrode exhibited a flexural strength of 65N/mm² and a hardness of 95Hrc, enabling stable, high-speed EDM operations without cracking or chipping. During testing, the electrode maintained over 98% dimensional stability even after 12 hours of continuous discharge. The client saw a 50% reduction in electrode consumption and a 35% improvement in overall machining speed. Furthermore, the smooth surface finish eliminated the need for post-polishing, reducing labor costs significantly. This case exemplifies how Dongmei’s integration of world-class materials, advanced equipment, and expert engineering delivers tangible ROI for clients in the automotive sector. As an authorized distributor of SGL Carbon in Guangdong and Fujian provinces, Dongmei ensures rapid access to premium-grade graphite materials, giving customers a competitive edge in fast-paced industrial environments.

• ISO9001:2015 Certified Manufacturing:

Dongguan Dongmei Graphite Industrial Co., Ltd. is proud to hold ISO9001:2015 certification—a globally recognized standard for quality management systems. This certification reflects our rigorous adherence to process control, continuous improvement, and customer satisfaction. A real-world example of this commitment comes from a solar photovoltaic client in Foshan who needed high-purity graphite sintering boats for their silicon wafer production line. The client required materials with minimal metal contamination and consistent thermal performance under extreme conditions (up to 1800°C). Through our closed-loop quality system, every batch of graphite raw material was traceable from sourcing to final inspection. We utilized SGL R8510 and R8710 grades, both certified with ash content below 0.02%, and implemented in-process checks at each stage—from raw material blending to impregnation, purification, and coating. Each sintering boat underwent non-destructive testing (NDT) and dimensional verification before shipment. The result? Zero rejection rate across 12 consecutive batches, with all units passing the client’s stringent acceptance criteria. The client reported a 25% reduction in wafer breakage rates and improved uniformity in crystal growth. This success story underscores how Dongmei’s ISO9001:2015 framework isn’t just a certificate—it’s a daily operational discipline that drives reliability, consistency, and innovation. Our ability to integrate certification with real-world performance has made us a preferred supplier for high-tech industries where failure is not an option.

--- Exceptional Customer Service and Support ---

• Tailored Technical Assistance:

One of our most impactful cases involved a semiconductor equipment manufacturer in Xiamen that struggled with inconsistent EDM results when producing graphite components for vacuum chambers. Despite using imported graphite, they experienced premature wear and surface irregularities. Dongmei’s technical team conducted an on-site assessment and discovered that the issue stemmed from improper electrode design and mismatched material selection. We proposed switching from standard graphite to SGL R8710, paired with optimized electrode geometry and cooling channel integration. Our engineers worked closely with the client’s R&D team to simulate discharge patterns and adjust parameters in real-time. We also provided training sessions on best practices for graphite handling, EDM settings, and post-processing care. Within three months, the client reported a 60% decrease in electrode failure rate and a 45% improvement in component lifespan. Moreover, the smoother surface finish reduced the need for secondary polishing, saving over 200 labor hours per year. This collaboration highlights Dongmei’s philosophy of being more than a supplier—we are a strategic partner. Our in-house technical experts, backed by decades of industry experience and access to global brands like SGL Carbon, deliver actionable insights that directly enhance our clients’ productivity and profitability. Whether it’s material selection, design optimization, or process troubleshooting, our tailored support ensures clients achieve optimal outcomes every time.

• Reliable After-Sales Service:

A key differentiator for Dongguan Dongmei Graphite Industrial Co., Ltd. is our comprehensive after-sales service network. One notable example involves a large-scale machinery manufacturer in Zhuhai that experienced unexpected downtime due to a cracked graphite electrode used in a die-casting mold. While the issue was rare, the client urgently needed a replacement within 48 hours to avoid production delays. Thanks to our in-house cargo transportation fleet and rapid response protocol, we dispatched a new R8500 graphite electrode—machined to exact specifications—within 36 hours of receiving the request. Upon arrival, our field engineer conducted a full installation check and provided on-site guidance on maintenance procedures. The client praised our responsiveness, stating that the quick turnaround saved them over $15,000 in lost revenue. Beyond emergency replacements, we offer regular follow-up visits, performance audits, and digital monitoring tools for clients using high-volume graphite systems. For instance, one solar panel producer now receives quarterly reports analyzing electrode wear patterns and recommending preventive maintenance schedules. These proactive measures have helped prevent over 12 potential failures in the past year alone. By combining fast logistics, expert support, and data-driven service models, Dongmei ensures that our clients never face disruptions caused by material failure—proving that true partnership means standing by you long after the sale is complete.
