Precision doesn’t happen by accident.
It takes a team committed to being exceptional every day. A team that cares about our customers, takes pride in its work, and understands what it means to manufacture heavy-duty bulk material handling equipment 100% in the United States of America. 🇺🇸
Within our industry, PMM has earned a reputation as the “Heavy-Duty Guys,” as one well-known rotary airlock manufacturer once put it.
We’ll take that as a compliment.
At Precision Machine & Manufacturing, we build equipment for the applications where standard equipment often falls short.
Easy-flowing, low-moisture materials? Absolutely.
Highly abrasive materials? That’s what we do.
High moisture? Low flow? Sticky, gummy, difficult-to-handle materials? Bring them on!!
From Rotary Valve Airlocks and Rotary Airlock Feeders to Heavy-Duty Screw Conveyors, PMM engineers and manufactures equipment designed to keep material moving, especially when the application gets tough.
Easy material or difficult material. Routine application or severe duty. PMM is built for the hard stuff!
No reason to use the "light-duty guys" for one type of material and then the "heavy-duty guys" for another type within your bulk material handling system, make one call to Precision Machine & Manufacturing, Inc. and let all the materials flow equally!
That’s why customers across industries have trusted PMM for nearly 50 years.
🇺🇸 American Made. Heavy-Duty Built. Engineered to Perform.
