Quality Detail
Close-up views of tooling precision, machined features, surface finishes, and inspection procedures.
Plating is a common requirement for zinc die cast hardware, lock components, connector housings, decorative parts, and corrosion-resistant assemblies. KastMfg supports plating and related surface finishing through qualified finishing partners coordinated with our die casting and inspection workflow.
For broader finishing options, see die casting surface finishing.
Common Plating Applications
| Application | Typical Requirement |
|---|---|
| Zinc lock bodies | Decorative finish, wear resistance, corrosion protection |
| Hardware components | Chrome, nickel, or zinc-based protective finish |
| Connector housings | Conductive or shielding-related surface requirements |
| Consumer-facing parts | Consistent color, gloss, and cosmetic surface |
| Industrial fittings | Corrosion resistance and assembly durability |
Plating feasibility depends on alloy, surface condition, part geometry, and cosmetic standard.
Design Factors That Affect Plating
Buyers should review these points before tooling:
- Visible cosmetic surfaces
- Sharp edges and high-current-density areas
- Deep recesses that may plate unevenly
- Threaded holes that need masking
- Porosity risk on visible surfaces
- Parting line and gate mark locations
- Required salt spray or corrosion test standard
KastMfg can provide DFM comments when plating is required.
Surface Preparation
Good plating starts before the plating line. KastMfg controls:
- Casting process stability
- Trimming and deburring
- Shot blasting or polishing where required
- Surface defect sorting
- Packaging between casting, finishing, and shipment
For cosmetic zinc parts, early agreement on the appearance standard is important. Sample approval should define acceptable gloss, color, parting line visibility, and minor surface marks.
