Temperature is a critical factor in electroplating processes. The uniformity, adhesion, gloss and porosity of plating layers are closely related to the temperature of plating bath. Whether for barrel plating, rack plating, electroless plating, anodizing or passivation, different plating types require specific temperature ranges.
Temperature is a critical factor in electroplating processes. The uniformity, adhesion, gloss and porosity of plating layers are closely related to the temperature of plating bath. Whether for barrel plating, rack plating, electroless plating, anodizing or passivation, different plating types require specific temperature ranges. Many electroplating factories are troubled by unstable bath temperature: slow heating, frequent temperature drift. When multiple production lines start heating at the same time, the pressure drops rapidly, resulting in uneven coating thickness, fogging, color difference, pinholes and peeling on workpieces. The rework rate remains high and affects delivery efficiency.
Many technicians repeatedly check temperature sensors, circulating pumps and heat exchange coils, and adjust heating time, yet the problem persists. A large number of electroplating workshops still rely on traditional boilers. These boilers feature obvious pressure fluctuation and serious hysteresis. It is hard to maintain constant temperature after heating up. Local overheating of the plating bath will decompose plating solution components and invalidate additives, raising the maintenance cost of plating liquid. Besides, traditional boilers require annual inspection and independent boiler rooms. Complicated maintenance will force the whole electroplating line to stop once overhaul is needed.
The core demand for electroplating tank heating is a continuous, stable and controllable heat source to keep the plating bath at the set process temperature. The smaller the temperature fluctuation, the more controllable the coating quality. Kaida premixed DC steam generator is specially developed for heating scenarios of electroplating, oxidation, pickling and other surface treatment baths. It solves temperature control problems of electroplating tanks with constant and accurate heat supply.
Equipped with an intelligent frequency conversion regulation system, Kaida premixed DC steam generator responds quickly. It dynamically adjusts steam output according to the real-time temperature of plating bath to achieve high-precision temperature control. The plating bath is heated indirectly through heat exchange coils without sudden temperature rise or drop. It maintains stable pressure even when multiple electroplating tanks heat simultaneously and runs smoothly for long-term constant temperature operation. Within a stable temperature environment, metal ions deposit at a uniform rate. Workpieces gain consistent coating gloss and better adhesion. Defects such as pinholes, color difference and fogging are greatly reduced, and the yield rate improves steadily.
Adopting premixed combustion technology, the equipment achieves sufficient combustion and low nitrogen emission, meeting environmental protection standards of industrial parks. Stable steam quality is guaranteed by the built-in steam-water separation structure. Indirect heat exchange prevents impurities from entering and contaminating plating solution, stabilizes the plating system and cuts consumption of brighteners and additives.
Electroplating workshops are usually compact with corrosive acid and alkali surroundings, putting forward strict requirements for equipment layout and safety management. This low-water-capacity equipment is exempt from boiler inspection. It does not require certified boiler operators or a separate boiler room, and can be installed close to the electroplating workshop. Shortened steam pipelines reduce heat loss and speed up heating. The modular design supplies steam on demand without continuous heat storage, saving more energy compared with traditional boilers. If one unit fails, other units can keep working to avoid full-line shutdown and guarantee continuous production.
It is widely applicable to various surface treatment processes, including zinc plating, nickel plating, chromium plating, copper plating, electroless nickel plating, anodizing, passivation, degreasing and oil removal tank heating. It fits both small-batch pilot production lines and large automatic continuous electroplating lines. After heat source upgrade, most electroplating factories can see obvious improvements: stable bath temperature, fewer defective coatings and lower chemical consumption.
For electroplating production, temperature determines product quality. Temperature probes and heat exchange coils lay the foundation, while a stable and accurate steam heat source is the key to high yield.
Kaida premixed DC steam generator features precise temperature control and stable operation. It meets heating demands of all kinds of electroplating tanks, stabilizes coating quality, reduces rework and helps surface treatment factories improve quality and efficiency.
