Custom Machined Plastic Parts and Components
CDS Plastics specializes in precision CNC machining of engineering plastics for industrial OEM and replacement part applications. We manufacture components requiring FDA compliance, metal detectability, chemical resistance, and self-lubricating properties for food processing, packaging, water treatment, material handling equipment, and more.
We reverse engineer obsolete components, work from customer drawings or samples, and machine complex geometries to precise tolerances. From single replacement parts to recurring production runs, we deliver the exact specifications your equipment requires.
Chicago-based manufacturing facility since 1986.

Sprockets
Self-lubricating plastic sprockets for chain drives. Corrosion-resistant, quieter than metal, and available in all ANSI standards with detectable options for food processing.Star Wheels
Precision machined star wheels for packaging and bottling lines. Custom pocket profiles for containers, with metal-detectable options and quick changeover designs.Rollers
Custom plastic rollers for conveyor and material handling systems. Lightweight, corrosion-proof alternatives to metal with reduced noise and maintenance requirements.Timing Gears & Timing Pulleys
Lightweight timing belt pulleys for synchronous drives. All tooth profiles (GT2, HTD, T-series) with reduced inertia for faster positioning and quieter operation.UHMW Guides
Self-lubricating UHMW chain guides and wear strips. Zero maintenance required, with significantly longer life than metal in abrasive conditions. FDA compliant options available.Bearing Blocks & Bearing Pillows
Greaseless plastic bearing blocks that eliminate contamination risks. Direct bore machining eliminates bearing inserts while providing maintenance-free operation in harsh environments.Timing Screws
Custom pitch timing screws for product spacing and orientation. Precise helical profiles for bottle handling, container positioning, and high-speed packaging applications.
Engineering Expertise for Your Plastic Parts Needs
CDS Plastics machines direct replacement components for worn, damaged, or obsolete plastic parts. Working from samples, drawings, or specifications, we produce parts that fit existing equipment. Expedited service available for emergency breakdowns. Part specifications and CAD files maintained for future orders.
Send worn parts for dimensional capture and replication. Our reverse engineering service documents critical dimensions, tolerances, and geometric features using precision measurement equipment. Complete CAD documentation provided. Essential service for legacy equipment, imported machinery, and discontinued OEM parts.
Advanced 3, 4, and 5-axis CNC milling and turning centers hold tolerances to ±0.002" on critical dimensions. Capabilities include machining all engineering plastics: UHMW, Nylon, Acetal, PEEK, PTFE, and specialty grades including metal-detectable and glass-filled variants. Complex geometries, prototype through production quantities.
Material selection prevents field failures. Our engineering team guides selection based on chemical resistance, operating temperature, load requirements, FDA compliance, and wear characteristics. Virgin and reprocessed grades available, detectable plastics for food safety programs, specialty materials for extreme environments. Nearly 40 years matching materials to application requirements.
