Key Product Features
1. Custom Design Based on Drawings
WIN WIN supports custom plastic parts according to customer drawings and product designs. Buyers can provide dimensional drawings, 3D models, or other available design information for project evaluation.
Enclosure dimensions, wall thickness, internal mounting features, openings, and assembly interfaces should be reviewed during the design stage. These details help determine mold feasibility and the fit of the enclosure with the intended electronic components.
2. Multiple Plastic Material Options
Available material options include ABS, PP, PS, PE, PVC, PA6, HDPE, and other plastics, subject to project requirements and manufacturing suitability.
Material selection should consider mechanical performance, dimensional stability, heat exposure, chemical compatibility, appearance, and the intended operating environment. For battery-powered electronics, the material must also suit the verified product safety requirements.
The final resin grade should be confirmed before tooling and production.
3. Custom Injection Mold Manufacturing
WIN WIN provides plastic injection mold manufacturing for customized enclosure projects. Listed mold material options include 718, 738, NAK80, S136, 718H, P20, and other grades.
The appropriate mold steel depends on factors such as expected production volume, part geometry, resin selection, surface finish, and tooling requirements. WIN WIN can evaluate these factors with buyers before the project proceeds.
4. Flexible Surface Finishing
Surface treatment options include polishing, texturing, painting, and other treatments subject to design feasibility.
These options help brands develop enclosures that match their product appearance and positioning. Final surface requirements should be documented in the approved drawings or sample specifications.
5. OEM Customization for B2B Buyers
WIN WIN supports OEM customization based on customer designs. The service is suitable for brands, electronics manufacturers, product developers, and importers sourcing custom plastic enclosures.
Before ordering, buyers should confirm the minimum order quantity, mold ownership terms, sample approval process, production lead time, packaging, and quality inspection requirements with the WIN WIN team.
