SummaryJiangxi Ningheda New Material Co., Ltd. is a limited company with 126 employees specializing in the research, development, production, and sale of special graphite products. It provides OEM services for well-known brands and ODM services, with customization available from samples, designs, full specifications, and minor modifications. Its service system includes documented procedures and records for supplier assessment, corrective and preventive actions, and customer complaints. Production-related evidence includes random finished-product inspection, three quality inspectors, specified processing and measurement equipment, and documented inspection instructions. However, the supplier reports no new products in the past year, no available SDK, no overseas warehouse, showroom, agent, or branch, and no participation in offline trade shows. Financial credibility, certification holding, and customer cases cannot be determined from the provided information.
Supplier typeThe supplier is identified as Jiangxi Ningheda New Material Co., Ltd., a limited company with 126 employees and no stated affiliation with a larger company group. Its stated specialization is the research, development, production, and sale of special graphite, and its offered product scope is graphite products.
After-Sales capabilityThe supplier has documented and followed procedures for customer complaints, corrective and preventive actions, and service-capability assessment. However, it has no overseas warehouse, showroom, agent, or branch, and reports zero countries where overseas services are offered; this supports procedural complaint handling but not broad overseas service coverage.
R&D capabilityThe supplier states that it conducts research and development and provides ODM services, but also reports no new products during the past year and no available SDK. The evidence confirms R&D-related service availability but shows a stated recent-product-development limitation.
Production capacityThe supplier specializes in producing special graphite and reports a combined facility including cutting, profile-processing, CNC, and caliper equipment. It also has three quality assurance and quality control inspectors, documented inspection instructions, and random finished-product inspection, supporting established production and inspection operations.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, and minor customization. These options are stated consistently in both the R&D/design-service and quality-control information.
Client casesThe supplier states that it provides OEM services for well-known brands, which is evidence of brand-customer service experience. No customer names, project descriptions, product examples, or verifiable case details are provided, so the depth and relevance of customer cases cannot be fully assessed.
Product Q&A
Q:Will the mold stick during use, causing defects on the cutting tip surface?
A:
No. The product is made from 99.9% high-purity, low-ash graphite, which is chemically stable and does not react with metal powders or diamond raw materials at high temperatures. Combined with its natural self-lubricating properties, demolding is smooth, with no sticking, no scarring, and no impurity adhesion, ensuring the appearance and quality of the finished cutting tips.
Q:What is the approximate service life of a graphite mold? Can it be reused?
A:
This mold features a dense structure and excellent resistance to oxidation and thermal shock. Under standard atmospheric sintering conditions, it can be reused 30-40 times; its service life can be further extended in a vacuum sintering environment, significantly reducing consumable replacement costs compared to ordinary graphite molds.
Q:Can the mold be customized to fit my cutting head dimensions?
A:
We support full-range customization. Based on the customer's cutting head length, thickness, and specifications, we can customize the overall mold dimensions, number of cavities, arrangement (three rows-top, middle, and bottom-or double-layer arrangement), and special-shaped structures. We can also machine the mold precisely according to drawings or samples.
Q:Why do cutting heads sintered using this mold have higher precision and more consistent quality?
A:
The mold's base material has uniform electrical resistivity and balanced thermal and electrical conductivity, ensuring consistent temperatures throughout the sintering process. This eliminates issues such as uneven hardness in the cutting heads and porous formation. Additionally, the ultra-low coefficient of thermal expansion ensures no deformation at high temperatures. Combined with precision CNC machining processes, this precisely locks in the cutting head dimensions, resulting in exceptional
Q:How can I tell when a graphite mold needs to be replaced?
A:
We recommend replacing the mold when the following signs appear: 1. Sintered cutting heads are out of tolerance (larger or smaller than specified), indicating that the mold cavity has worn out; 2. Visible pits or deposits appear on the cutting head surface, indicating that the mold's working surface has been damaged or oxidized; 3. Abnormal fluctuations in the sintering current or temperature curve, which may indicate a change in the mold's electrical resistance. Regularly inspecting the mold's
