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:Manufacturer or trading company?

Direct OEM manufacturer - 6,000 sqm, 17 years, 40+ CNC machines, ISO9001, 3D CMM.

Q:What is 4140 alloy steel?

Chromium-molybdenum alloy steel offering high strength (up to 1,080 MPa), excellent toughness, and good fatigue resistance.

Q:Why use nickel plating on 4140 timing components?

Electroless nickel plating provides uniform coating thickness, corrosion resistance comparable to 304 stainless steel, high surface hardness (up to 1,000 HV), and low friction - all critical for precision timing applications.

Q:What is the difference between electroless and electroplated nickel?

Electroless nickel is an autocatalytic chemical process providing perfectly uniform coating thickness even on complex geometries. Electroplated nickel requires an external power source and may have uneven thickness on complex shapes.

Q:What is the typical nickel plating thickness?

5 - 50 um, customizable based on application requirements.
