Torus Z525 Multi-Station Enamel Rater for Can Ends

Designed for the food and beverage industry, this powerful multi‑station solution enables high‑throughput enamel rating, helping quality teams quickly assess coating porosity and detect any areas of metal exposure that could lead to corrosion, leakage, or product contamination.

Brought to you by Torus, our specialist metal packaging testing brand, the Z525 Multi‑Station Enamel Rater is purpose‑engineered for manufacturers who need fast, reliable lacquer integrity testing across multiple can ends.

Why measure the porosity of can ends?

Enamel rating is a critical quality control step for can end production, ensuring the protective lacquer layer applied during manufacturing is continuous and defect‑free. The Z525 Multi‑Station Enamel Rater evaluates porosity levels using precise milliamp (mA) measurement to determine whether any metal substrate is exposed beneath the coating. With options for 4‑station or 8‑station configurations, this system dramatically increases testing efficiency, making it ideal for facilities handling large batches of ends or running continuous inspection cycles.

Reliable, multi-station enamel rater options

Designed with reliability and operator usability in mind, the multi‑station system delivers consistent readings across every channel, ensuring uniform quality control throughout the batch.

• Multi‑station capacity: Test up to 4 or 8 can ends, significantly boosting throughput.
• Fast, repeatable enamel rating measurements: High‑precision mA readings ensure reliable detection of coating defects and metal exposure.
• Ideal for high‑volume can end production: Perfect for food, beverage, and aerosol can end manufacturers requiring scalable quality control.
• Improved quality assurance workflow: Streamlined multi‑end testing reduces operator time and supports efficient batch inspection.
• Consistent, uniform measurement across stations: Each station maintains stable and repeatable performance, ensuring reliable comparison across samples.
• Seamless data integration: Compatible with leading SPC systems for centralized reporting and process optimization.
• Supports compliance and product safety: Helps manufacturers prevent corrosion, leakage, and contamination by verifying lacquer integrity early.

Effortless Enamel Rating Data Transfer

The Z525 Multi‑Station Enamel Rater integrates effortlessly with leading SPC and data‑analysis platforms, including our advanced Torus GaugeXplorer measurement software, or our Visionary QC™9 Software and SEAMetal SPC. Providing real‑time insights and traceable enamel rating results for better process control and improved production decision‑making.

Coating and lacquer expertise

We are pleased to be able to offer a variety of enamel raters, from our versatile Z525 Manual Benchtop Enamel Rater, through to automatic solutions, such as the Z604 Automatic Enamel Rater or the Z313 Automatic Beverage Can Enamel Rating Gauge.

We also have other coating inspection equipment critical for the metal packaging industry. For instance, you may be interested in our SpecMetrix® In-line Coating Measurement Systems, ideal for the inline inspecton on of the coating thickness on blanks and coils. Additionally, we also have the Torus Z340 Automatic Coating Analyzer, which is especially designed to check for the lacquer thickness and distribution on cans.
