Yijin Solution Expands CNC Machining Services for Aluminum Parts

Yijin Solution, a precision manufacturing company based in Boca Raton, Florida, has expanded its services to offer CNC machining of aluminum parts for buyers in the automotive, aerospace, medical, and energy industries. The company’s services include CNC milling, CNC turning, drilling, tapping, and reaming, catering to a range of industries that require precision machining of aluminum components.

Yijin Solution specializes in four wrought aluminum grades: 6061, 7075, 2024, and 5052. These grades are commonly used in the production of housings, brackets, enclosures, and heat sinks due to their light weight and ease of machining. The company’s CNC milling process cuts complex shapes from solid blocks of metal, while the turning process shapes round parts as they rotate. Spindle speeds can reach up to 20,000 RPM, ensuring efficient and precise machining.

The company’s standard tolerance is ±0.05 mm, with ISO 2768 as the general reference. For critical dimensions, precision features can reach ±0.01 mm. The minimum wall thickness is 0.5 mm, and the minimum hole diameter is 0.3 mm. Surface roughness ranges from Ra 0.4 to 3.2 mm, ensuring a high-quality finish on the machined parts. Post-processing options include anodizing (Type II and Type III), powder coating, bead blasting, and plating.

Yijin Solution also provides quality inspection through coordinate measuring machine (CMM) inspection, first article inspection, and PPAP Level 3 documentation. The company holds ISO 9001, ISO 13485, IATF 16949, and ISO 14001 certifications, which are particularly relevant for buyers in the automotive and medical industries. IATF 16949 is a quality management standard for the automotive supply chain, and ISO 13485 applies to medical device manufacturing.

For ordering and lead times, Yijin Solution offers a mini order that can ship in as little as 7 days, while standard production runs take 10 to 15 days. The company does not enforce a fixed minimum order quantity, making it suitable for both prototypes and 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, which helps catch issues such as walls or holes that fall below the listed minimums.

Yijin Solution’s capabilities extend beyond aluminum machining. The company offers a range of precision manufacturing services, including CNC machining, sheet metal fabrication, and custom fasteners. It also provides die casting, injection molding, and 3D printing to support industries such as automotive, aerospace, medical, and energy.
