APPLICATION REVIEW
Select Innozinc by reviewing corrosion requirements together with post-plating fabrication. Compare the standard and high-corrosion-resistance grades against your current component specification and service conditions.
Provide the current coating system, required thickness, white- and red-rust acceptance criteria, and test method. Compare SST results under equivalent specimen and assessment conditions; do not convert test hours into years of service.
Identify welding, bending, roll grooving, threaded assembly and subsequent painting requirements. Evaluate fabricated areas and joints using the drawing tolerances and applicable gauge criteria.
Share the substrate, dimensions, weight, production volume and surface requirements. Review rack or barrel processing suitability, then agree on the sample specification and inspection items.
Technical references: review the coating cross-section and topcoat adhesion data alongside the grade-specific test tables. Confirm the application specification through evaluation of actual components.
COATING STRUCTURE
The inorganic ceramic film infiltrates and bonds within the micropores of the ceramic zinc plating layer, forming a dense composite barrier that delivers high corrosion resistance.
FIVE CORE PROPERTIES
From corrosion protection to welding, forming and fastening. Ceramic zinc composite plating connects your manufacturing process with the requirements of the service environment.
The inorganic ceramic film infiltrates and bonds within the micropores of the ceramic zinc plating layer, restricting the ingress of corrosive species and protecting the substrate.
The thin plated layer supports post-plating welding. Welding parameters and weld-area post-treatment are specified for the joining method.
An average plating thickness of approximately 8 µm supports bending, roll grooving and threaded assembly. Post-plating fabrication quality is controlled to the part geometry and dimensional tolerances.
Chemical-substance testing and production parameters guide material and process management. Energy and water use are compared on an equivalent production basis.
We select rack or barrel processing and define production parameters for the component size, geometry and throughput.
PRODUCTION PROCESS
Rack plating secures components on purpose-designed fixtures. Barrel plating processes small components in rotating barrels. We select the process for the component geometry and production throughput.
Watch the Rack Line Components are secured on plating racks designed for their size and geometry.
Watch the Barrel Line Small components are batch-plated in rotating barrels.
INNOZINC ANSWERS
Product selection:
specifications, fabrication and samples
Standard-grade Innozinc has a representative maximum SST range of 720–1,000 hr; high-corrosion-resistance Innozinc-h has a range of 1,500–2,000 hr. Grade selection reflects the service environment and manufacturing and assembly requirements.
Innozinc supports post-plating welding, bending and roll grooving. Sample evaluation reflects the welding method, forming radius and dimensional tolerances, and establishes post-treatment conditions for the fabricated areas.
The stated average thickness for standard Innozinc is approximately 8 µm. Actual thickness can vary with substrate geometry, pretreatment and process conditions.
SST measures corrosion resistance under controlled salt spray conditions. Product specifications include the specimen substrate, pretreatment, thickness and white- and red-rust acceptance criteria. SST is a laboratory performance indicator, distinct from years of service.
Provide the substrate, dimensions, quantity, drawings or photos, and service environment. Our team will confirm the plating specification, sample quantity, cost and schedule.
Compare the required corrosion specification, coating thickness, dimensional tolerances, appearance, and post-plating welding, forming and assembly conditions. Assess substitution against the service environment and sample results for the actual component.
