The Miller Plastics staff has been mobilized in response to Covid-19.

Rest assured, we are fully operational and ready to help.

Acid process tanks are a specialty of Miller Plastic Products. Our advanced CNC machining capability allows us to produce very sophisticated, extremely high-quality plastic tanks to your custom specifications.

We also use the latest in computer welding technology to ensure integrity and longevity of our tanks, hoods, and plastic process appliances.  We back this up with a 5-year written warranty. 

Our welds are second to none, being very smooth and easily cleaned. Nothing leaves our shop with a saw cut edge or a sharp edge. Every pickling tank is individually cut out on high-tech CNC routers.


Our experience can help you choose the right material for your particular custom plastic tank. We’re just a phone call or click away.

We offer free design assistance and can provide 2D or 3D drawings using AutoCAD and SOLIDWORKS

Our tanks are engineered using FEA (Finite Element Analysis) to maximize performance and allow for minimal bowing of the fabrication.
