About Our Low-Volume Metal Manufacturing
At ZH Precision, we transform your CAD designs into production-ready metal parts through our four core processes: CNC Machining, Die Casting, Sheet Metal Fabrication, and Aluminum Extrusion. Our low-volume production service eliminates the barriers of traditional manufacturing—no high MOQ, fast lead times, and flexible iterations to support agile product development.
We cater to diverse needs: market testing, pilot runs, custom components, and urgent replenishment. With ±0.005 mm precision and lead times as short as 3–5 days (standard 7–15 days, 48-hour expedited available), you get production-grade quality without compromise.
Every project includes free DFM (Design for Manufacturability) analysis and dedicated engineering support, ensuring optimized designs, consistent performance, and a seamless transition from prototype to low-volume manufacturing.
How to Process Low-Volume Manufacturing
What is the key to achieving excellence in low-volume manufacturing? Is it the choice of raw materials, advanced machining methods, or the precision of the final product?
At ZH Precision, we believe it’s a combination of all three. Many clients worry that low-volume or prototype production may sacrifice quality compared to mass manufacturing. Rest assured — our team applies the same rigorous standards in materials selection, CNC machining, die casting, and quality inspection, ensuring every batch meets exact specifications.
As experts in high-mix, low-volume production, our operations are designed to be fully scalable — from a single precision-machined prototype to hundreds of custom parts. Our robust supply chain guarantees material availability without minimum order restrictions. Meanwhile, our integrated digital manufacturing system connects every machine and work center, allowing us to allocate resources efficiently and deliver short-run parts with speed and consistency.
