Understanding the OEM process for custom aluminum windows<\/strong> is essential for architects, contractors, and developers sourcing from China. A proper OEM partnership involves design development, prototyping, fabrication, quality control, and logistics \u2014 all coordinated with your project timeline.<\/p>\n\n
Runheng has been providing OEM\/ODM aluminum window manufacturing services<\/strong> since 1995. This guide walks through each stage of the process so you know exactly what to expect when partnering with a Chinese window factory.<\/p>\n\n
Share your architectural drawings, performance requirements, and design intent. The manufacturer reviews your specs against their extrusion systems and suggests optimizations for cost, performance, or manufacturing efficiency. Runheng maintains 136 product models across 5 series to match most project requirements.<\/p>\n\n
The manufacturer produces detailed shop drawings for your approval. This is where engineering depth matters \u2014 Runheng has 69,484 engineering documents accumulated over 31 years, ensuring every detail is captured before fabrication begins.<\/p>\n\n
