Your Custom Metal Fabrication Partner in Ningbo, China
Conwhole was born from a real need we saw in the custom hardware industry — clients struggling to bridge the gap between design and delivery. Our answer: make custom metal parts simpler, faster, and more reliable for global B2B clients.
Who we are: Conwhole is a Ningbo-based custom metal fabrication company with 25+ years of industry experience. We are not a product catalog supplier — we are a manufacturing partner that turns your drawings into finished, quality-verified metal parts.
From Design to Delivery — One Partner, Zero Handoffs
“Conwhole” stands for Consolidation + Wholeness — we consolidate resources and craft seamless experiences. Since the beginning, we’ve committed to doing one thing well: making custom metal parts simpler, faster, and more reliable for our global B2B clients.
