Haizol is a custom parts marketplace connecting companies to instrumentation manufacturers in China, matching a submitted drawing to factories that machine the housings and enclosures inside a sensor or gauge build. 81.5% of instrumentation manufacturers on Haizol run CNC milling and 45.9% run Swiss machining, the processes behind that housing and enclosure work.
A branded gauge or transmitter listing shows a name and a datasheet. Matching the enclosure or mounting bracket inside it to a different build is a separate question entirely, one a datasheet was never built to answer.
85.9% of instrumentation manufacturers on Haizol hold ISO 9001, and 23.7% hold IATF 16949 for automotive-adjacent instrumentation work. Aluminum alloy (88.1%), stainless steel (87.4%), and brass (81.5%) cover the metals a housing or enclosure build needs, all recorded on the same page that lists the process behind them.
A shop's real capability is visible before a drawing is sent, right on its Haizol record: production equipment listed by brand and model, the same field carried by every instrumentation manufacturer on the platform. A specific factory can be messaged directly from its listing, or the same drawing can go out as one inquiry to the whole matching set, returning quotes from 8+ verified factories within 24 hours.
Submit a drawing for a housing, enclosure, or mounting bracket, and let instrumentation manufacturers on Haizol who already run the right process quote against it.
Instrumentation manufacturers on Haizol machine the housings, enclosures, and mounting components inside a sensor or gauge build, from a submitted drawing.
A dedicated account manager works every sourcing inquiry on Haizol, helping shortlist matching instrumentation manufacturers and refine the RFQ itself, a CNC milling tolerance or an ISO 9001 requirement stated clearly enough to reach relevant, high-quality factories on the first try.
Certifications and current status are listed directly on each instrumentation manufacturer's Haizol entry, visible ahead of any commitment, the same verification a buyer would otherwise have to run manually before sending a deposit.
8+ verified instrumentation manufacturers quote back within 24 hours of a single sourcing inquiry, with that same account manager coordinating the shortlisted factories directly.
