What is the advantage of surface treatment?

Surface treatment adds functions like erosion and corrosion resistance or improves hardness, lowering cost compared to using entire cemented alloy while maintaining good performance.

What materials are used for the valve trim?

The valve trim is made of Tungsten Carbide combined with Stainless Steel, offering high hardness, wear resistance, and strength.

AI-Powered supplier vetting

SummaryThe supplier operates in research, development, production, and sales of cemented carbide, powder metallurgy materials, new metal wear-resistant materials, and related technical services. It reports ISO9001:2015, ISO14001, and ISO45001:2018 certifications, documented corrective-action and complaint-handling procedures, and recent fire drills. R&D evidence is positive: new products were developed during the past year, ODM services are available, and multiple customization modes are offered. However, the supplier reports no in-stock capacity, overseas warehouse, overseas showroom, overseas agent or branch, valid manufacturing-capacity contract with an affiliated subcontractor, or OEM service for well-known brands. Financial information is inconsistent and insufficient for a reliable assessment. Customer-case evidence is limited to participation in the 2025 OTC offline trade show.

Supplier typeThe supplier is identified as a combined company whose business covers R&D, production, sales, and technical consulting for cemented carbide, powder metallurgy, and metal wear-resistant materials, including metal surface treatment. This supports classification as a manufacturing-oriented supplier with related technical services.

CertificationsThe supplier reports ISO9001:2015, ISO14001, and ISO45001:2018 certifications. These explicitly indicate coverage of quality, environmental, and occupational health and safety management systems.

R&D capabilityThe supplier reports new products within the past year, ODM service availability, and broad R&D-related design support. The absence of an available SDK is a limitation, but SDK availability is not sufficient by itself to negate the demonstrated product-development and ODM capabilities.

Production capacityThe stated business scope includes production of cemented carbide, powder metallurgy materials, and new metal wear-resistant materials, and the supplier reports 27 qualified suppliers plus written supplier-assessment procedures and records. Nevertheless, it reports no in-stock capacity and no valid contract with an affiliated subcontractor, so production capability is supported but operational capacity evidence is incomplete.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM service availability, providing direct evidence of broad customization support.
