Boca Raton, FL 33431, United States, 16th Oct 2026 – Yijin Solution, a well-known provider of precision manufacturing services, is offering precision aluminum CNC machining services in China, with parts produced at the company’s own factory in Shenzhen. The service covers the milling and turning of wrought aluminum to customer drawings. The company has published its tolerances and lead times, and each quote includes a design review before production begins.
The offer is aimed at buyers in the automotive, aerospace, medical and energy industries who source machined aluminum parts from China. It forms part of the company’s CNC machining in China, which is provided alongside sheet metal fabrication and custom fasteners.
What the Service Covers
The company lists four wrought aluminum grades: 6061, 7075, 2024 and 5052. Wrought grades are rolled or extruded into stock before being cut to shape. Machining processes include CNC milling, CNC turning, drilling, tapping and reaming. Milling cuts complex shapes from solid blocks of metal, while turning shapes round parts as they rotate. The company states that spindle speeds reach up to 20,000 RPM.
Aluminum is widely machined because it is light and cuts readily. Typical parts include housings, brackets, enclosures and heat sinks.
Buyers comparing overseas suppliers usually weigh the same few points: the alloys available, the tolerances a shop can hold, how quickly parts ship and whether a minimum order applies. The announcement sets out each of those points for aluminum work.
“Buyers who source aluminum parts from China often need three answers before they send a drawing: which grades are available, what tolerances are achievable and how long production takes,” said Gavin Yi, CEO of Yijin Solution. “This announcement sets those details out in one place.”
Published Capabilities
According to the company, the standard tolerance is ±0.05 mm, with ISO 2768 as the general reference. Precision features can reach ±0.01 mm on critical dimensions. Minimum wall thickness is 0.5 mm, and minimum hole diameter is 0.3 mm. Surface roughness ranges from Ra 0.4 to 3.2 μm. Post-processing options include anodizing (Type II and Type III), powder coating, bead blasting and plating.
For inspection, the company lists coordinate measuring machine (CMM) inspection, first article inspection and PPAP Level 3 documentation. It also cites ISO 9001, ISO 13485, IATF 16949 and ISO 14001 certifications.
Several of these relate to the industries named in the announcement. IATF 16949 is a quality management standard for the automotive supply chain, and ISO 13485 applies to medical device manufacturing. Buyers in those sectors often ask suppliers for matching documentation before placing an order.
Ordering and Lead Times
The company states that a mini order can ship in as little as 7 days, while standard production runs take 10 to 15 days. It does not enforce a fixed minimum order quantity. In practice, the shorter lead time typically suits prototypes and small batches, and the longer one suits production quantities.
Customers can upload up to 15 files in formats such as STEP, IGES, DWG, PDF and STL. Each quote reflects material grade, part complexity, tolerance requirements, order quantity and finishing. Every quote includes a design for manufacturability (DFM) review, in which engineers flag risk areas, suggest fixes and confirm the final specification before cutting starts. The review can catch issues such as walls or holes that fall below the listed minimums.
Looking Ahead
Requests for aluminum parts vary by alloy, tolerance and quantity, and Yijin Solution expects each one to be reviewed individually before production.
“Requests will keep varying by alloy, tolerance and quantity, so each drawing will continue to go through engineering review before production begins,” said Gavin Yi, CEO of Yijin Solution. “The aim is to keep the quoting process clear for each new request.”
