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:What is the biggest advantage of flat-mouthed graphite crucibles compared to standard crucibles?

Compared to ceramic, quartz, and clay crucibles, this flat-mouthed high-purity graphite crucible conducts heat faster, heats more evenly, and offers excellent thermal shock resistance, making it less prone to cracking under temperature fluctuations; they offer greater chemical stability, resisting acids, alkalis, and metal corrosion without contaminating the melted material; the flat-mouth design allows for easier operation, broader application scenarios, and a longer service life, making them f

Q:How do I select the appropriate size of graphite crucible?

You can choose a model based on the weight and volume of the material to be melted in a single batch, as well as the dimensions of your melting equipment. As a general rule, we recommend that the amount melted in a single batch does not exceed two-thirds of the crucible's capacity to prevent high-temperature molten material from overflowing. For small-scale experiments and jewelry melting, choose small-capacity models; for industrial batch smelting, opt for large-capacity custom models. Alternat

Q:Does the crucible need to be cooled immediately after use?

Never place a hot crucible directly on a cold metal surface or wet ground, as this can cause severe thermal shock and result in the crucible shattering. Use crucible tongs to remove it and place it on a dry graphite pad, refractory brick, or ceramic plate to allow it to cool naturally to room temperature.

Q:Can the same crucible be used to melt different metals?

We do not recommend mixing metals. Melting different metals can leave trace impurities, which may cause cross-contamination and affect the purity of the final product. We recommend using a dedicated crucible for each type of metal to ensure melting quality and the accuracy of experimental and production data.

Q:What is the minimum order quantity?

The minimum order quantity is 100 Kgs.
