About US
Maxflow builds solventless hash washing machines for growers who care about output, consistency, and cost.
We’re based in mainland China, where a deep manufacturing ecosystem lets great equipment get built without the inflated price tag. That’s our lane: practical machines, solid performance, and pricing that makes sense—because the supply chain is right here, and we’ve been in it for a long time.
Built by a factory, not a logo
We started producing equipment in 2008. Over the years, we’ve focused on what matters in real production: reliability, repeatability, and easy day-to-day operation.
- 2015: We developed and produced our first hash extraction centrifuge.
- 2018: We sold our first solventless hash wash machine internationally through import/export partners.
- Today: Hundreds of Maxflow solventless hash wash machines are in use overseas—previously sold through trading companies.
Why we’re selling direct now
For years, most international buyers found Maxflow through third-party traders. That worked—but it also meant extra markup, slower communication, and less transparency.
Now we’re opening direct sales to growers. Same factory. Same equipment. Straightforward support. And most importantly: factory pricing without the middle layer.
