Custom Plastic ComponentManufacturing.
Custom plastic manufacturing across commercial and medical industries — six processes, one partner. Three decades of experience means we recommend the method that's right for your part, not just the one we want to sell.
Made in the USA.
Every part is produced through our U.S. manufacturing partner network and held to ISO 9001:2015 and ISO 13485:2016 quality systems — domestic accountability from first quote to final shipment.
Three decades.
One honest partner.
Plastic Alternatives is a leader in commercial and medical custom plastic component production. From low-volume prototype runs to high-volume production programs, you work directly with industry veterans who understand the real trade-offs of tooling, materials, and methods.
We don't just quote — we help you choose. Our team has spent decades across all six major processes. That breadth means honest recommendations on the right method for your part.
Why work with us
- Process-agnostic guidanceSix capabilities, one project partner — honest recommendations on which method fits your part.
- Concept-to-production supportDesign review, tooling, prototyping, secondary operations, and packaging — coordinated by one team.
- Direct, responsive partnershipTalk to a principal. Quotes turn quickly, and the people quoting are the same people guiding your project.
Six capabilities. One partner.
From small precision parts to large structural assemblies, our six processes cover the full spectrum of custom plastic manufacturing — coordinated end-to-end through a single point of contact.
Injection Molding
High-volume precision parts with tight tolerances, from 28-ton to 1000-ton press capability.
View Process
Medical Molding
ISO 13485 clean-room molding for components in life-science and medical-device applications.
View Process
Vacuum / Thermoforming
Large, thin-walled parts and housings formed from sheet — efficient tooling for lower volumes.
View Process
Plastic Fabrication
Custom and prototype parts via CNC machining, routing, bonding, and assembly.
View Process
Rotational Molding
Seamless, stress-free hollow parts — tanks, housings, and large durable components.
View Process
Profile Extrusion
Continuous profiles and trim up to 9″ wide, with in-house wire-EDM die tooling.

Six processes.
One U.S. partner network.
From our base in Independence, Minnesota, we coordinate all six plastic processes across a vetted U.S. manufacturing partner network — held to ISO 9001:2015 and ISO 13485:2016 quality systems — managing tooling, production, finishing, and packaging for manufacturers nationwide.
Built for specification.
We produce custom components for manufacturers across regulated and demanding industries nationwide.
