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.
Why Choose Ocean Century for Precision Enclosures?
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.
Key Capabilities for Snap-Fit Enclosures:
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.

FAQ
Q: What is the minimum order quantity (MOQ) for custom enclosures?
A: MOQ depends on part complexity. For simpler enclosures, we can
start from 500 units. We also offer prototype batches for testing.
Q: Can you help optimize my design for molding?
A: Yes, our engineers will analyze wall thickness, rib placement, and
undercut angles to ensure moldability and long-term performance.
Q: How do you ensure dimensional accuracy?
A: We use high-precision molds machined from hardened steel, and each
production batch is sampled and measured with CMM equipment to
verify tolerances.
