For electronic devices, appliances, and automotive modules, a well-designed plastic enclosure is critical for both aesthetics and functionality. Ocean Century specializes in high-precision injection molding of custom plastic enclosures, with particular expertise in snap-fit designs that ensure secure assembly, easy maintenance, and clean appearance.

With 142 advanced injection presses (50T to 1850T) and a team of experienced mold engineers, we deliver enclosures with exceptional dimensional accuracy and repeatable snap-fit performance, from prototypes to high-volume production.

• Snap-Fit Engineering Expertise: Snap fits demand precise control of material flow, shrinkage, and tolerances. Our DFM (Design for Manufacturability) analysis identifies optimal gate locations, draft angles, and undercut handling to ensure reliable engagement and durability over repeated cycles.
• High Precision & Tight Tolerances: We maintain tolerances on critical features, using advanced CNC machining of molds and in-process CMM (Coordinate Measuring Machine) verification.
• Material Selection Support: Depending on your application, we guide you in choosing the right resin (ABS, PC, PC/ABS, Nylon, etc.) for strength, flexibility, chemical resistance, and UL flame ratings.
• Scalable Manufacturing: Our automated production lines enable monthly output exceeding 1 million parts while maintaining strict quality standards. Mold lifespans of 300,000 to 500,000 shots ensure long-term project stability.

• Complex Geometries: Multi-cavity molds, side-action cores, and lifter systems for internal and external snap features.
• Secondary Operations: Assembly of internal components.
• Surface Finishing: Texturing, painting, silk-screen printing, and laser marking.
• Quality Assurance: ISO 9001 & IATF 16949 certified. 100% critical dimension inspection before shipment.
