--- Unmatched Quality and Performance of Graphite Molds ---

• Exceptional Properties of Graphite Materials:

Dongguan Dongmei Graphite Industry Co., Ltd. has consistently delivered superior graphite mold solutions that have transformed manufacturing processes across multiple sectors. One notable real-world case involves a Tier-1 automotive glass manufacturer in Shenzhen that faced persistent challenges with mold deformation and surface finish during the hot bending process of 3D curved smartphone glass. The client was using conventional copper electrodes, which suffered from high wear, thermal distortion, and long processing times. After switching to Dongmei’s SGL R8710 ultra-fine graphite electrodes—featuring an average particle size of just 3μm and a mirror-like surface finish—the company reported a 40% reduction in electrode wear, a 35% increase in discharge speed, and a near-perfect surface finish with minimal post-processing. This breakthrough enabled the client to achieve consistent batch-to-batch quality, reduce downtime by over 50%, and shorten overall mold development cycles from 14 days to just 7. The exceptional thermal stability (coefficient of thermal expansion: 5.7×10⁻⁶K⁻¹), high thermal conductivity (100W/m·K), and low ash content (<0.02%) of R8710 ensured minimal dimensional deviation even under repeated high-temperature cycles. Furthermore, the material’s isotropic structure eliminated directional weaknesses, making it ideal for complex geometries. This case exemplifies how Dongmei’s scientifically engineered graphite materials deliver not only performance but also tangible ROI through enhanced productivity and reduced operational costs.

• Comprehensive Technical Support for Customers:

Beyond material supply, Dongmei’s success lies in its holistic technical support system. A semiconductor equipment manufacturer in Fujian Province faced recurring issues with graphite sintering fixtures cracking during high-temperature processing due to thermal stress and impurities. The client approached Dongmei seeking a solution. Rather than simply supplying standard graphite boats, Dongmei’s senior technical team conducted on-site analysis, reviewed the furnace cycle parameters, and recommended customized DHM-970 Japanese joint venture graphite fixtures with optimized pore structure and compressive strength (170MPa). They also provided full-process guidance on pre-bake procedures and handling protocols to minimize micro-cracking. Within three months of implementation, the client reported zero fixture failures over 1,200 production runs—up from an average of 8 failures per month before. Additionally, Dongmei’s in-house machining team delivered precision-machined components within 48 hours, supported by a dedicated logistics fleet ensuring same-week delivery. This level of responsiveness, combined with expert application consulting, underscores Dongmei’s customer-first philosophy. Their ISO9001:2015 certification and SGL Carbon authorization guarantee traceability and consistency, giving clients confidence in every stage of production. These real-world outcomes highlight how Dongmei doesn’t just sell graphite—it partners in innovation, turning complex engineering challenges into scalable, reliable solutions.

• Precision Engineering for Automotive Glass:

In the rapidly evolving automotive industry, where safety and design aesthetics are critical, precision molding of curved glass panels demands materials with unmatched thermal and mechanical stability. Dongmei Graphite successfully partnered with a major Chinese EV manufacturer to develop custom 3D graphite hot bending molds for side-window glass used in electric vehicles. The project required molds capable of maintaining sub-micron dimensional accuracy after repeated heating and cooling cycles. Dongmei supplied SGL R8650 graphite blocks—known for their ultra-fine grain structure (5μm average), high flexural strength (65N/mm²), and excellent thermal conductivity (100W/m·K)—which were then precision-machined into complex concave and convex profiles. During testing, these molds demonstrated less than 0.02mm warping after 100 thermal cycles, far surpassing traditional metal or lower-grade graphite alternatives. The client achieved a 99.8% yield rate in glass forming, significantly reducing scrap and rework. Moreover, the lightweight nature of graphite—only 1/5 the weight of copper—reduced machine load and energy consumption. This project not only accelerated the client’s time-to-market by 30% but also became a benchmark for future mold designs. The success story was later featured in a leading industry journal, highlighting Dongmei’s role in advancing next-generation automotive glass manufacturing through innovative material science and tailored engineering solutions.

• Innovative Solutions for Semiconductor Manufacturing:

The semiconductor industry relies heavily on ultra-pure, high-performance materials to ensure device reliability. A leading Chinese wafer fabrication plant encountered frequent contamination and inconsistent sintering results when using standard graphite boats. The root cause was traced to residual metals and high porosity in the raw material, leading to particle shedding and uneven heat distribution. Dongmei stepped in with a comprehensive solution: supplying SGL R8710 premium graphite parts with <0.02% ash content and a dense, uniform microstructure. These components were manufactured under strict cleanroom conditions and underwent multi-stage purification and coating processes. Post-implementation, the client observed a 90% reduction in particulate contamination, a 25% improvement in wafer yield, and a 40% decrease in furnace maintenance frequency. The high thermal conductivity (100W/m·K) and low coefficient of thermal expansion (5.7×10⁻⁶K⁻¹) ensured uniform temperature profiles across the entire boat, critical for achieving consistent doping and crystallization. In addition, Dongmei provided on-site training for operators and developed a digital tracking system for each batch of graphite components, enabling full traceability. This case illustrates how Dongmei’s integration of premium materials, advanced processing, and digital service capabilities delivers measurable value in high-stakes, high-precision environments—solidifying its reputation as a trusted partner in semiconductor innovation.
