Haizol is a verified sourcing marketplace connecting companies with electronics parts manufacturers in China: housings, heat sinks, chassis, connectors, and brackets built around a circuit board. A separate contract electronics manufacturer handles board population and SMT assembly. 82% of electronics parts manufacturers on Haizol work in aluminum alloy, the metal a heat sink or enclosure needs for thermal performance. 85% of electronics parts manufacturers on Haizol also hold ISO 9001.
A shop that quotes fast on every process will quote a heat sink or a molded housing just as fast, whether or not it has actually cut a mold cavity or machined a finned heat sink before. A directory listing can't tell the difference.
That's what a factory's page on Haizol settles: machinery listed by model shows whether a shop has actually machined a heat sink or cut an injection mold before. Among electronics parts manufacturers on Haizol, 28% run EDM in-house, the process that cuts the mold cavity behind an injection-molded housing.
22% of electronics parts manufacturers on Haizol combine metal machining and injection molding, so a heat sink and its matching housing can be quoted and built from a single factory.
Every factory page on Haizol lists machinery by model, remaining capacity, and export ratio, so capability can be verified before an inquiry is sent. A record shows a factory's direct contact details, or Haizol can run the outreach: one sourcing inquiry returns quotes from 8+ verified factories within 24 hours, comparable on price and capability.
Electronics parts manufacturers on Haizol cover the housings, heat sinks, chassis, connectors, and brackets around a board, while board population and full assembly go to a separate contract electronics manufacturer.
A factory's listing on Haizol shows whether it runs CNC milling, EDM, or injection molding, and what materials it works in, before any drawing changes hands.
Some electronics parts manufacturers on Haizol run metal machining and injection molding in the same facility, so the heat sink and housing for the same device can be quoted and built together.
MOQ and lead time aren't listed on a Haizol factory entry. Both vary by process: a stock aluminum heat sink section quotes faster than a part needing a new injection mold. Ask for MOQ and lead time once a quote comes back from a sourcing inquiry.
Electronics parts manufacturers on Haizol list remaining capacity as a field on their factory record, so you can check whether they have room to take on your project.
