Plastic Injection Molding & Overmolding
A Full Suite of Plastic Injection Molding & Overmolding Capabilities
Plastic injection molding is a manufacturing process that melts plastic material until it's malleable enough to be pressure-injected into a mold, forming a high-quality part with incredible accuracy.
Overmolding is exactly what it sounds like: it's a variation of injection molding that allows you to mold one material over the other. It's commonly used to create soft-touch handles, grips, or multi-colored parts.
We have the equipment and expertise required to confidently handle a wide range of plastic injection molding and overmolding projects. We work with a variety of materials and can create impact-, scratch-, and chemical-resistant products with a specific stiffness and gloss appearance to ensure the final result is exactly what you're looking for.
The VMS Advantage
We provide a number of key advantages to help our plastic injection molding & overmolding clients get ahead of the competition.
Diverse Capabilities
We offer an expansive collection of plastic molding equipment, featuring 14 machines with various capabilities and sizes, which allows us to do more for our clients than the average plastic injection molding manufacturer.
In-House Value
Keeping your project in-house from start to finish helps you save time and slash production costs. In addition to our custom plastic injection molding & overmolding capabilities, we offer a whole collection of finishing services, so you can go from prototype to production under one roof.
New Product Development and Existing Product Manufacturing
Whether you’re working on new product development or simply looking to ramp up production on an existing product, we’re your trusted partner. Our seasoned team of experts will support you at every step of the NPD process, giving your new product the attention and dedication it deserves. And, if your existing product needs a new manufacturing base, we’ll run with your design and tooling to increase production with ease.
Standard and Custom Tooling Options
We'll align our tooling resources with your budget and timeline to get the job done. As a VMS client, you'll be able to choose from our vast collection of current in-house tool dies, or work closely with our tooling engineer to make modifications. If neither of those options work, we'll design and build a brand new tool that perfectly matches your project's unique criteria.
Global Sourcing
Our global sourcing team combines in-house coordination with on-the-ground efforts in the international marketplace to expand your sourcing options from both domestic and international suppliers.
Quality Certifications
Our manufacturing facilities are all ISO certified (ISO 9001), and our team of experts is well-versed in UL, CSA, NSF, ETL, and CE standards.
