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.

Production capacityThe supplier reports more than 15 years of machining-industry experience, its own factory, multiple production lines, and more than 10 production lines. It lists CNC machining, milling, grinding, wire cutting, and turning capabilities, serves several industrial sectors, and states lead times within 15 working days in both peak and off-peak seasons.

Customization capabilityThe product and service descriptions cover precision CNC machining, CNC turning, grinding, wire cutting, machinery parts, testing, and assembly. The supplier states that its production lines can meet different product needs and requirements, supporting customization, although no detailed engineering workflow, tolerance range, tooling policy, or sample-development evidence is provided.

Product Q&A

Q:Are you a manufacturer or trading company?

We are a direct manufacturer - 2,000 sqm, 17 years of experience, 30+ CNC machines, ISO9001, 3D CMM. Send inquiry for a live video tour of our shop floor.

Q:What is the difference between 316 and 316L?

316 has a slightly higher carbon content (up to 0.08%) while 316L has lower carbon (max 0.03%). For most cooling components, 316 is sufficient. 316L is preferred for welded applications to prevent sensitization.

Q:Why is 316 preferred over 304 for cooling applications?

316 contains 2.0-3.0% molybdenum, providing superior resistance to pitting and crevice corrosion from chlorides in cooling water.

Q:Is 316 suitable for seawater cooling systems?

316 provides good corrosion resistance in seawater but may be susceptible to crevice corrosion in stagnant conditions. For seawater service, super duplex or titanium is recommended.

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

1500mm x 500mm x 500mm - suitable for large heat exchanger components, pipe flanges, and custom cooling parts.
