Plastic Injection Molding in Chicago, IL
JDI Plastics is an ISO 9001-certified custom manufacturer providing thermoplastic injection molding services for customers throughout the greater Chicago area and across the United States. Since 1995, we have specialized in molding complex thermoplastic components for customers requiring consistent quality, responsive communication, and reliable lead times.
Whether you are sourcing a difficult-to-mold part or looking for a domestic plastic injection molding and assembly partner, JDI Plastics supports projects from molding through secondary assembly and packaging under one roof.
Thermoplastic Injection Molding in Chicago: Tailored to Customer Needs
JDI Plastics works with a broad range of thermoplastic materials to support application-specific performance requirements. We process a wide range of commodity and engineering-grade thermoplastics to support diverse mechanical, thermal, and environmental requirements. Our material capabilities include:
- Nylon, Polycarbonate, ABS, and Acetal
- PVC (rigid and flexible), HDPE, LDPE, and TPE
- High-performance resins, including PEEK, LCP, Polysulfone, and PET
- Acrylic, Styrene, and numerous custom blends
JDI Plastics specializes in molding complex components involving difficult geometries, specified resins, tight tolerances, and multi-component assemblies. If another molder turned down your part, we want to discuss it with your team.
Our Chicago facility utilizes modern molding equipment and automation systems to support a wide range of part sizes and production volumes. Standard production lead times typically run around four weeks, depending heavily on project scope.
A note on tooling: We source molds from trusted suppliers on your behalf. You work with a single, dedicated point of contact throughout the project, rather than coordinating separately with tooling vendors and molding suppliers.
Plastic Injection Molding Capabilities: From Prototyping to Assembly
JDI Plastics manages molding, secondary operations, assembly, and packaging within a single production workflow. Our in-house secondary operations remove reliance on outside vendors and simplify supply chain management for customers. These services include:
- Mechanical and component assembly
- Ultrasonic welding for insert and plastic applications
- Heat staking and solvent bonding
- Soldering and wire assembly
- Pad printing and hot stamping
- Custom labeling and bar coding
- Custom packaging for shipment preparation
This comprehensive scope matters immensely for purchasing managers. Rather than managing separate suppliers for molding, assembly, and packaging, you partner with a single plastic molding company that handles all phases. Executing every step after mold release on-site keeps quality consistent and simplifies supply chain coordination while maintaining process consistency.
We maintain ISO 9001 certification and support ISO 13485-compliant medical manufacturing requirements. Production volumes range from a few thousand parts annually to millions. Our location just northwest of Chicago is preferred by customers who need domestic, geographically close supply chains and fast, on-time delivery.
