It reports ISO 9000, ISO 9001, ISO 14000, and ISO 14001 certifications, as well as 6–10 R&D engineers and 6–10 quality-control staff. The company offers OEM, ODM, and its own KUMTHAI brand, and exports to multiple global regions. Its stated lead time is within 15 working days in both off-peak and peak seasons. Evidence supports production, customization, certification, and technical-service capabilities. However, the slices do not provide sufficient evidence to assess financial credibility or specific customer cases.

Supplier typeThe supplier is identified as both a trading company and manufacturer/factory, with a limited-company structure and an address in Zhengzhou, Henan, China. Its stated focus includes the design, development, production, and sales of superhard abrasive materials, indicating an operating model that combines manufacturing and trading activities.

CertificationsThe supplier reports holding ISO 9000, ISO 9001, ISO 14000, and ISO 14001 management-system certifications. These stated certifications provide explicit evidence of formal quality and environmental management systems.

After-Sales capabilityThe company states that it provides customer service, professional technical support, and product services through a technology R&D team and service team. This supports the existence of technical and service resources, although the slices do not specify warranty terms, service response procedures, or post-sale performance records.

R&D capabilityThe supplier reports a professional technology R&D team, 6–10 years of total R&D-engineer experience, advanced production and testing equipment, and product development involving synthetic diamond micron powders from 40 nm to 125 microns. These details explicitly support R&D and product-engineering capability.

Production capacityThe supplier reports multiple production workshops, three production lines, advanced equipment, annual synthetic diamond productivity of 120 tons, monthly output of 25 million carats of micron powders, and around 30 million carats of crushed synthetic diamond grits. It also states a lead time within 15 working days in both peak and off-peak seasons, supporting substantial and responsive production capability.

Customization capabilityThe supplier explicitly offers OEM and ODM services in addition to its own KUMTHAI brand, according to customer requirements.

Product Q&A

Q:What is the service life of Boron Carbide nozzles compared to other materials?

Boron Carbide nozzles have a service life of 2000-2500 hours with steel grit, 1000-1500 hours with silica sand, and 500-1000 hours with brown aluminium oxide. This is significantly longer than Tungsten Carbide (500-800h with steel grit) and Silicon Carbide (600-1000h with steel grit).

Q:How does the Venturi design improve efficiency?

The Venturi nozzle improves gas dynamics by reducing or ceasing vortex existence, which greatly reduces pressure loss. It increases abrasive export speed by more than double and improves efficiency by 15-40% compared to straight-hole nozzles, while consuming 20% less abrasive.

Q:Can the nozzle specifications and shapes be customized?

Yes, the product is customized. We can design and produce complex shapes according to customer requirements. Special requirements on specifications and chemical composition can be satisfied through discussion. Customers are welcome to send drawings for quotations.

Q:What is the lead time for production?

The average lead time is within 15 workdays for both peak season and off-season.

Q:What payment terms are accepted?

We accept LC (Letter of Credit), T/T (Telegraphic Transfer), and D/P (Documents against Payment).
