Screw Machine Parts is a high-precision CNC machining manufacturer based in Dongguan, Guangdong, China. Its legal entity information points to Dongguan Zhuohang Ltd / Zhuohang Precision Machining Factory. It is not a standard consumer-facing ecommerce platform, but a B2B custom manufacturing service website where customers submit drawings or samples by email, fax, or courier to request quotes and place orders.
The website states that it offers 3-axis, 4-axis, and 5-axis CNC machining, CNC milling, turning, grinding, wire cutting, Swiss-type lathe machining, and mill-turn machining. It can also handle downstream processes such as anodizing, electroplating, spraying, polishing, welding, sub-assembly, and custom packaging. Supported materials include aluminum, copper, brass, steel, stainless steel, titanium alloys, and plastics such as ABS, POM, nylon, PTFE, and PEEK. Its target industries include automotive, aerospace, electronics, medical, telecommunications, robotics, and machinery, making it more of an industrial parts supply-chain provider.
The site does not publish unit prices or provide an online pricing calculator. Instead, quotes are based on drawings and requirements, with a typical promise of a 24-hour response and a quote within 48 hours. It supports orders starting from 1 piece, making it suitable for prototyping. Payment methods include PayPal, Western Union, bank wire transfer, T/T, and L/C, while long-term customers may be able to negotiate Net 30/45/60 terms. For logistics, it mentions using DHL, EMS, FedEx, TNT, UPS, and similar accounts, or letting the factory handle shipping, but it does not disclose clear shipping costs or delivery timelines.
Its strengths are that it discloses a fair amount of company registration information, address details, certification systems, and quality commitments. It also mentions ISO 9001, IATF 16949, ISO 14001, as well as inspection capabilities such as CMM and XRF. Defective parts can be repaired, reworked, remade, or refunded free of charge. The drawbacks are that the website has a low level of ecommerce functionality, with no online ordering, instant pricing, order tracking interface, or public case studies and reviews. First-time cooperation will still require considerable manual confirmation.
It is suitable for overseas buyers, hardware startups, industrial product sellers, equipment vendors, and manufacturing companies that need access to China-based CNC supply chains for prototyping, small-batch production, or mass production. The main content does not specify how accessible the site is from China, so this is considered unknown. If you need a more standardized online quoting experience, you may want to compare it with Xometry, Hubs, Protolabs, Fictiv, or machining suppliers on Alibaba.com.
