Custom Injection Molding
injection molding Capabilties
PSI offers a full spectrum of injection molding processes — from conventional small and midsize parts through large structural components and advanced techniques that reduce weight, cost, and cycle time. Every process is supported by the same engineering discipline, process controls, and quality systems.
High-volume production of precision small and midsize parts across a wide range of thermoplastics — with tight tolerances, multi-cavity tooling, and consistent dimensional repeatability at scale.

Structural and large-format part molding for components that demand size, strength, and dimensional stability — including thick-wall applications not typically associated with conventional injection molding.

Optically clear components molded in transparent resins — requiring specialized tooling, processing discipline, and handling protocols to achieve defect-free clarity at production volumes.
Learn More
Multi-material molding that bonds a second material over a substrate — creating parts that combine hard structural cores with soft-touch surfaces, ergonomic grips, or sealed interfaces in a single molded component.
Learn More
A low-pressure molding process that produces large, lightweight structural parts with a solid skin and cellular foam core — delivering high strength-to-weight ratios at lower tooling cost than conventional injection molding.

An advanced molding process that injects pressurized nitrogen gas into the melt to hollow out thick sections — producing parts with superior surface quality, reduced weight, and elimination of sink marks on visible surfaces.

The PSI Difference
Partnership From Day One
From the first design conversation to final assembly, our team works alongside your team at every stage. Engineering, molding, decoration, and assembly all happen under one roof, with a single team accountable for quality, timing, and consistency from start to finish.
No handoffs to outside vendors. No gaps in communication. Just experienced people who know your part, understand your standards, and are invested in getting it right.
Less guesswork.
No surprises.
Better Outcomes.
PSI asks questions before a tool is cut — what does this part need to do, where does it live, what can’t it fail at? Our engineers work alongside yours from day one, so the people building your parts are in lock step with the people who designed them. Good engineering shouldn’t feel complicated. It should just feel like it works.
Mold Transfer capabilities
Already have tooling? Transferring to PSI is easier than you think.
PSI has a proven process for qualifying and transitioning molds from other suppliers — minimizing disruption to your program while improving the quality, service, and cost structure of your molded parts. Whether you’re reshoring, consolidating suppliers, or simply looking for a better partner, we make the move straightforward.
