Midland Plastics Warehouse and machines

What We Do

Plastics | Material Distribution

Midland stocks large inventories of sheet, rod, tubing and profiles in a wide variety of plastic types, among them acrylic, polycarbonate, polyethylene, ABS, polypropylene, PVC, styrene, and more.

Custom Manufacturing

We produce high-quality, custom plastic component parts utilizing advanced 3-axis CNC and 5-axis CNS routing, machining and milling technologies.

We also use traditional hand processes, like heat bending, to produce high-quality fabricated parts.

Forming

Midland manufactures parts using vacuum, pressure and ridge forming technology. To ensure consistent, accurate and efficient trimming and routing of formed parts, we use robotic-like 5-axis routers to enhance our forming processes.

Our Customers

At Midland Plastics, we have developed relationships with many of the top plastic’s manufacturers, which lets us offer our customers a wider selection of quality products.

In manufacturing, we carefully plan and review each new project. Throughout the manufacturing process, we carefully monitor each phase of our production to ensure we meet our customers’ expectations for the highest quality plastic components.
 

History

Founded in 1945 as a distributor of stock plastic shapes, Midland Plastics, Inc., headquartered in New Berlin, Wisconsin, is a privately held distributor celebrating over 75 years in business and is one of the oldest and largest plastics suppliers in the Midwest.

Our expansion into custom manufacturing and fabrication lets us serve our customers better by assisting them with all of their plastic needs, whether in CNC sawing and machining, fabrication, forming or custom extrusions.
