    Ordered a batch of custom alloy housing cavities for embedded control hardware. The CMM inspection data is traceable for each lot. The flatness and position tolerance of mounting holes are well controlled. Parts fit seamlessly on our PCB assemblies. Fast response and flexible MOQ for custom instrument parts.

    I’m impressed with ChenRong flexibility on small batch metal machining. We needed mixed-material parts including aluminum and brass for our instrument project. Every piece was checked before packing. Their sales and engineering team

    Great small batch CNC machining service from ChenRong. We ordered stainless steel custom parts for test equipment. Many factories refuse tiny orders, but ChenRong accepts low-volume jobs without extra high charges. Surface finish meets our requirements and delivery is on time. We will continue cooperation for our R&D test batches.
