AI-Powered supplier vetting

SummaryDongguan Guanneng Automation Technology Development Co., Ltd. is a China-based combined business entity identified in one record as a trade company, operating in Dongguan, Guangdong. It reports more than 15 years of machining-industry experience, while the company establishment date provided is 2018. Its stated capabilities include CNC machining, milling, grinding, wire cutting, turning, testing, assembly, and after-sales service. The supplier reports its own factory, multiple production lines, more than 10 production lines, and ISO9001:2015 certification. It serves machining, biomedical, automotive, semiconductor, automation, and petroleum machinery industries, and exports to East Asia, Europe, and North America. Lead times are stated as within 15 working days in both off-peak and peak seasons. Evidence is insufficient to assess financial credibility, innovation output, formal outsourcing or contract controls, overseas warehousing, traceability, or named customer cases. The audit record is dated November...

CertificationsThe supplier reports holding an ISO9001:2015 certificate and describes a dedicated quality control department and strict ISO9001-based production management system. A BV audit is also recorded for November 9, 2023 through November 8, 2024, although the audit result is listed as 0 without an explained scale.

After-Sales capabilityThe company description explicitly includes after-sales service among its integrated activities and states that it serves domestic and overseas enterprises. However, the records provide no specific response process, service coverage, repair policy, or overseas service infrastructure; overseas warehouse and showroom capabilities are marked unknown.

Q:What is 17-4 PH stainless steel?

17-4 PH (UNS S17400) is a martensitic, precipitation-hardening stainless steel that provides high strength and hardness along with excellent corrosion resistance.

Q:Why is 17-4 PH used for engine mechanical parts?

17-4 PH offers high tensile strength (up to 1,310 MPa), excellent fatigue resistance, good elevated temperature properties, and can be heat treated to achieve a wide range of mechanical properties.

Q:What heat treatment condition do you recommend for engine components?

H900 - maximum strength (>= 1,310 MPa), ideal for high-load structural and valve train components. H1025 for high strength with improved toughness.

Q:What is the maximum part size you can machine?

1500mm x 500mm x 500mm - suitable for large engine components, structural brackets, and custom parts.
