Can the efficiency of automated line zinc plating be doubled? The HL-611 chloride‑based zinc plating additive holds the key!

HL-611 Chloride-Based Zinc Plating Additive

For automated production lines, “stability” and “speed” have always been the core priorities—ensuring consistent, top‑grade coating quality while boosting output and efficiency without compromising productivity. In the zinc‑plating process, a reliable additive directly sets the upper limit for both production efficiency and product quality. Guangdong Haolun Environmental Protection has specifically developed the HL‑611 chloride‑based zinc‑plating additive, which, with its four key strengths—“fast, precise, stable, and robust”—has won widespread acclaim from manufacturers across industries such as automotive components, hardware fabrication, and electronic parts.

HL-611 Chloride-Based Zinc Plating Additive

1 Fast and precise! A dual breakthrough that elevates the coating’s texture to the max.

In fast-paced, automated production environments, “light‑out speed” serves as the “pulse” of the production line, directly determining output capacity per unit of time. One of the HL‑611’s key highlights is its dual excellence in both light‑out speed and zinc‑plating speed:

① Extremely rapid brightening and fast zinc deposition: Compared with conventional additives, this acid‑zinc additive delivers significantly faster brightening, enabling the formation of a uniform, mirror‑like coating within the specified plating time; its brightness performance in low‑current regions is particularly outstanding.

② Exceptional compatibility and precise fulfillment of demanding requirements: Superior deep‑plating performance compared to cyanide zinc plating, effortlessly coating hard‑to‑plate areas such as deep holes and recesses, and suitable for both rack plating and barrel plating applications.

③ With full leveling power, it reduces rework and boosts efficiency: its unique active ingredients fill in minute surface imperfections, delivering a uniform, bright plating finish. It is suitable for automotive fasteners, electronic connectors, and other components, eliminating the issue of “fast polishing inevitably resulting in a rough surface” and minimizing rework such as grinding and polishing.

2. Stable and cost-effective! The secret to worry-free production costs.

Automated production lines are most vulnerable to “chain breaks” mid‑process; the HL‑611 ensures robust production reliability with its exceptional stability:

① Stable performance: HL‑611 effectively addresses the longstanding issues of traditional additives—high impurity levels and significant contamination—producing minimal decomposition byproducts. The plating bath remains clear and transparent like water over long periods, with no yellowish side products. It operates within a temperature range of 16–65°C, has a cloud point exceeding 100°C, and maintains stable performance even under high‑temperature conditions.

② Consistent reliability: During the electro‑galvanizing process, key parameters such as pH and dispersing power remain stable, with no batch‑to‑batch variations or long-term performance degradation.

③ Reduced consumable usage: The brightener has a high concentration, resulting in a consumption rate that is only 1/4 to 1/3 of that of conventional processes, and its consumption remains unaffected by rising tank temperatures.

3. Multi-system compatibility! Exclusive optimization for automated lines.

HL-611 boasts excellent compatibility, seamlessly accommodating potassium‑salt, ammonium‑salt, and sodium‑salt systems. Notably, the ammonium‑salt plating bath exhibits superior resistance to impurities and discoloration compared to the potassium‑salt system, making it particularly well suited for automated production lines.

① Enhanced impurity tolerance: During continuous feeding on automated production lines, contaminants carried by the workpieces can easily degrade the plating bath. In contrast, the ammonium‑salt system can effectively accommodate a higher level of impurities, reducing the risk of bath disposal and extending its service life. Coupled with the high‑area current‑expansion characteristics of HL‑611, it effectively prevents burn‑off in the high‑area regions of the workpiece, further improving the yield of qualified parts.

② Superior resistance to discoloration: The coating features a fine, dense crystalline structure and exhibits strong adhesion of the passivation film. Once formed, the coating is less susceptible to environmental factors that can cause discoloration or darkening, thereby enhancing product appearance consistency and bolstering market competitiveness.

Applicable Scenarios

Whether it’s the precision requirements of automotive components, the production‑volume demands of hardware fittings, the deep‑plating needs of complex workpieces, or the aesthetic standards of electronic parts, HL‑611 chloride‑based zinc‑plating additive delivers precise performance, addressing key pain points such as low efficiency, quality variability, and mounting environmental pressures.

Summary

HL-611 chloride‑based zinc plating additive, with its four core advantages—rapid brightening, excellent leveling, stable performance, and strong impurity resistance—perfectly meets the electroplating production needs of varying scales and applications, addresses key operational pain points, and delivers a dual leap in both efficiency and quality!
