The Crestwood Industries Difference

When you search for “injection molding companies near me,” you’ll find plenty of options. However, not all plastic molding companies are the same. Crestwood Industries stands out with a deep commitment to our clients, our ISO 9001:2015 certification, and a collaborative approach that includes you in every step of the manufacturing process.

Our core values shape everything we do:

• Creative Mindset: We approach every project with an open and innovative spirit.
• Customer Dedication: We always go the extra mile for our customers.
• Simplicity and Clarity: We make the process straightforward and easy to understand, without confusing jargon.

This philosophy means we don't just make parts; we build lasting relationships. We aim to be more than a supplier—we become an extension of your team, dedicated to helping your business thrive.

From Concept to Reality: Our Design & Build Process

Our process is transparent and collaborative, designed to transform your ideas into high-quality plastic products efficiently. Here’s a look at how we work.

Step 1: Understanding Your Vision

The journey starts with a deep dive into your project. We sit down with you to understand your product goals, applications, and specific needs. We discuss everything from intended use and production volume to material preferences. This initial phase is key to identifying potential challenges early and developing effective solutions.

Step 2: Design Assistance and Optimization

Unlike some plastic injection molding companies in Illinois, we actively help refine your design for manufacturability. Our engineering team reviews your concepts and offers expert advice on material selection, wall thickness, and other features to optimize the injection molding process and reduce costs.

Step 3: Precision Tooling

The quality of your final product relies on the precision of the mold. Crestwood Industries excels at creating complex, multi-cavity tools in-house. Our experienced team designs and builds molds that ensure optimal material flow, consistent cooling, and clean part ejection, achieving tight tolerances.

Step 4: Prototyping and Validation

Before full-scale production, we encourage prototyping to validate your design. We offer both 3D printing for quick evaluations and injection-molded prototypes using production-grade materials. This step allows you to test function and fit, preventing costly changes later.

Step 5: High-Quality Production

With a finalized design and approved tooling, we move to production at our state-of-the-art Illinois facility. Our 22 injection molding presses can handle runs from 500 to over 5 million units. We follow strict ISO 9001:2015 quality standards, with real-time monitoring to ensure every part meets your exact specifications.
