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:Can you design a mold cavity based on my target ingot weight?

Yes, please provide the target ingot weight, metal type, and photos or drawings. If drawings are unavailable, we can calculate dimensions based on weight and estimated density.

Q:Which metals are suitable for casting in this graphite ingot mold?

The molds are suitable for precious metals (gold, silver, platinum) and non-ferrous metals (copper, aluminum, zinc, etc.) without causing contamination.

Q:Can a mold with minor damage be repaired?

Superficial scratches and small chips can be machined out, but through-cracks require replacement to prevent bursting and safety hazards.

Q:Why do my graphite ingot molds crack or burst after a few uses?

Cracking is usually caused by thermal shock (pouring into a cold mold) or internal moisture. Ensure preheating and store in a dry environment.

Q:Can you provide samples? What is the lead time?

Free samples are available for quality inspection (shipping costs apply), with a lead time of 3-10 days. Bulk orders take 7-25 days.
