From Concept to Reality: Our Design & Build Process

Our approach is designed to be transparent and collaborative, transforming your ideas into high-quality plastic products efficiently. Here’s how we do it.

Step 1: Understanding Your Vision

The journey begins with a deep dive into your project. We sit down with you to understand your product goals, target applications, and specific requirements. This initial discovery phase is crucial for identifying potential challenges and developing effective solutions before they impact your timeline or budget.

Step 2: Design Assistance and Optimization

Unlike other plastic injection molding companies in Illinois, we actively participate in refining your design for manufacturability. Our engineering team provides expert recommendations on material selection, wall thickness, draft angles, and other features to optimize the injection molding process and reduce costs.

Step 3: Precision Tooling

The quality of your final product depends on the precision of the mold. Crestwood Industries excels in 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, holding tight tolerances to guarantee accuracy.

Step 4: Prototyping and Validation

Before committing to full-scale production, we encourage prototyping to validate your design. We offer both 3D printing and injection molded prototypes, allowing you to conduct functional testing and confirm your material choice, preventing costly changes down the line.

Step 5: High-Quality Production
