Custom Injection Molding

Custom Injection Molding Built for Performance at Any Scale

From concept to production, Quantum Plastics delivers precision, consistency, and 24/7 manufacturing capacity.

Quantum Plastics delivers high‑precision, scalable custom injection molding solutions for Tier 1 manufacturers and OEMs across North America. With more than 200 presses, advanced automation, and a deeply experienced engineering team, we support complex programs from concept through full‑scale production.

Our presses range drastically in size, from 30 to 3000 tons, in order to fulfill a variety of large and small customer needs.

Inside our clean, quiet and bright facilities our machines run 24 hours a day, every day. Our facilities ensure consistent output, rapid response, and the capacity to take on programs of any size. Our team of dedicated professionals work toward one goal; to bring our customers the very best.

The Quantum Plastics team of engineers collaborate with customers every step of the way, no matter where in the process- whether a mold is already built looking to be transferred to a facility or if the process is just beginning with a drawing and an idea.

A Full‑Scale Custom Molding Partner

As a Tier 2 molding partner, custom injection molding is at the core of what we do. Whether you need a single component or a multi‑part assembly, Quantum Plastics provides the expertise, technology, and production infrastructure to deliver consistent, repeatable results.

Capabilities Include:

Custom injection molding for simple to highly complex geometries
Vertical and horizontal molding
Electric, hybrid, and hydraulic press technologies
Presses ranging from 30 to 3000 tons
Tight‑tolerance molding for demanding industries
High‑volume, lights‑out production supported by robotics
Low‑volume and specialty molding for niche applications

This breadth of capability allows us to mold everything from micro components to large structural parts with equal precision.

Engineering‑Driven Manufacturing

Every successful molding program begins with strong engineering. Quantum Plastics integrates engineering support at every stage to reduce risk, improve manufacturability, and ensure long‑term production stability.

Our Engineering Support Includes:

Design for Manufacturability (DFM)
Mold transfer, validation, and optimization
Material selection guidance
Prototyping and sampling
Tooling maintenance and repair
Integrated product development

Your team gains access to engineers who understand tooling, processing, automation, and downstream assembly — ensuring a smoother launch and fewer surprises.

Automation‑Enhanced Precision

Robotics at Quantum Plastics Quantum Plastics has invested heavily in robotics and automation to elevate quality, consistency, and throughput. These investments include:

Electric/hybrid presses paired with robotics
Pick‑and‑place systems
Sprue pickers
Collaborative robots (cobots)
Automated conveyors and indexing systems

Automation allows us to:

Reduce cycle times
Improve repeatability
Lower scrap rates
Maintain consistent part quality
Reduce labor costs
Support lights‑out production where appropriate

This is custom molding built for modern manufacturing — efficient, data‑driven, and highly controlled.

Materials Expertise for Every Application

Custom injection molding requires deep knowledge of materials and how they behave under pressure, heat, and stress. Quantum Plastics works with a wide range of thermoplastics, engineered resins, and specialty materials to meet performance, regulatory, and environmental requirements.
