Conductive Containers, Inc. and Crestline Plastics, Inc. provide a full spectrum of specialized packaging and handling solutions through vertically-integrated manufacturing capabilities. From corrugated mailers and injection molded cases to large-format custom plastics and precision optics packaging, we deliver high-performance protection for mission-critical technologies.
Every solution is engineered, manufactured, and validated with a commitment to ESD and FOD control—ensuring reliability when failure is not an option.
Engineering & Prototyping
Our engineering team partners with you to translate complex requirements into custom packaging designs that protect your most sensitive parts and components. Using 3D-rendering, extensive material knowledge, and rapid prototyping, we validate designs early—reducing risk, ensuring manufacturability, and accelerating time-to-market.
Our in-house tooling capabilities provide precision and flexibility from concept through production. By designing and machining tooling internally, we maintain tight control over quality, tolerances, and lead times.
Box-making
We provide high-performance outer package and shipping solutions tailored to your requirements, ensuring maximum protection for mission-critical components. Each solution is engineered to deliver comprehensive physical, ESD, and FOD protection from shipment through final use.
We offer a wide range of foams designed for long-term performance in manufacturing, shipping, and storage applications. Leveraging advanced fabrication capabilities, we deliver custom-engineered foam solutions tailored to each customer’s specific cushioning, weight, and fragility requirements.
Thermoforming
We produce custom-fit trays, clamshells, and large-format parts, with thermoforming capabilities that extend to oversized and complex geometries. These solutions provide part-specific packaging for electronics, optics, defense systems, and medical devices.
Our injection molding capabilities support high-volume, repeatable production of durable protective packaging. Using conductive and dissipative polymers for ESD-safe applications—or sturdy clear plastic for optics—we manufacture trays, cases, and containers engineered for long-term performance in mission-critical applications.
Parts Cleaning
We provide advanced particulate cleaning for thermoformed parts, validated to IEST-STD-CC1246E Level 300. Utilizing ISO Class 7 cleanroom processes and state-of-the-art particulate trap filtration, components are delivered clean, sealed, and ready for immediate use. Every part undergoes rigorous inspection, cleaning, and secure packaging, ensuring consistent reliability in mission-critical applications.
We specialize in machining precision fixtures designed to securely hold sensitive optics during transport, cleaning, or processing—delivering maximum protection at every stage. Our CNC capabilities support both short- and long-run applications, ensuring consistent, high-quality results with tight tolerances.
CNC Routing
We provide in-house prototyping and full-production tooling, combined with precise CNC trimming and cutting of thermoformed parts, to ensure consistent, high-quality results. With quick-turn capability, automatic nesting, and tight tolerances even on heat-sensitive materials, our engineering team develops custom solutions tailored to your exact specifications.
