Environmental Friendly Electroplating Production Line for Hardware and Electronics

Equipment Description:

1. Process flow example

Feeding → Degreasing/pickling (alkaline solution ultrasonic cleaning + hydrochloric acid treatment) → Electroplating (galvanizing/nickel plating, current density 1-5A/dm²) → Three-stage water washing → Passivation (trivalent chromium or chromium-free process) → Centrifugal drying (800-1200r/min) → Hot air drying (60-80℃) → Unloading.

2. Technical features

High efficiency: Continuous operation mode, single-line daily processing capacity can reach 2-8 tons, and the shortest cycle time is 35 seconds.
Low maintenance: Simple mechanical structure (mainly hydraulic/chain drive), low maintenance cost, service life ≥10 years.
Environmental protection: Closed tank + acid mist collection system (purification efficiency ≥90%), wastewater reuse rate ≥80%.
‌Flexible expansion‌: supports slot hopping, switching between multiple plating types (such as copper plating and silver plating), and the changeover time is ≤15 minutes.

3. Application scenarios‌

4.Selection points‌
‌Process matching‌: Prioritize models that support chromium-free passivation and slot-hopping processes to meet environmental regulations.
‌Capacity adaptation‌: Select the slot capacity based on the daily processing volume (2-8 tons) and workpiece size (slot length 500-2500mm).
‌Control accuracy‌: Ensure that the current density control error is ≤±0.1A/dm² and the temperature fluctuation is ≤±1℃.

Main structures and components:

1. Track system
Annular layout: The tanks are arranged in the order of the process flow, the tank width is uniform (matching the size of the hanger), and the horizontal pitch is determined by the processing time and the moving beat.
Transmission mode: hydraulic drive (large equipment) or chain drive (small equipment), to achieve vertical lifting or swing lifting, and the running speed is adjustable (beat time 35 seconds to 1 minute).

2. Tank unit
Functional tank group: including electroplating tank, degreasing tank, pickling tank, washing tank, passivation tank, etc., made of PP/PVC or stainless steel, and fully enclosed structure to reduce volatilization.
Size design: The length of the tank is determined by the processing time, and the depth and lifting height are determined by the size of the workpiece and the hanger.

3. Transmission and lifting mechanism
Vertical lifting device: servo motor drives the chain/guide rail, positioning accuracy ≤±0.5mm, load capacity ≤200kg, supports slot jumping, dripping and other actions.
‌Hanger design‌: detachable titanium alloy/PP hanger, suitable for small workpieces (such as screws, connectors), adjustable horizontal pitch.

4. control system‌ ‌

PLC integrated control‌: preset multiple sets of process parameters (current density, time, temperature), support automatic alarm and abnormal shutdown.

‌Sensor positioning‌: photoelectric sensor and RFID track the hanger position in real time to ensure process synchronization.

5. auxiliary system‌ ‌

Circulation filtration system‌: magnetic pump + 5μm precision filter, plating solution recycling rate ≥95%.
‌Temperature control system‌: titanium heating tube or indirect cooling device, temperature fluctuation ≤±1℃.
‌Environmental protection module‌: acid mist collection (alkali spray tower, purification efficiency ≥90%), wastewater reuse (RO reverse osmosis, COD≤50mg/L).

‌6.power supply and electrode system‌ ‌

Rectifier‌: provide stable DC power supply, current density control accuracy ≤±0.1A/dm².
‌Annular electrode‌: The electrode is arranged in a ring shape to ensure that the current is evenly distributed in the electroplating area and improve the consistency of the coating.

‌Technical features‌
‌Fixed process path‌: Suitable for scenarios with mature processes and single products, and cannot be reversed.
‌High stability‌: The mechanical structure is complex but the control is simple, the service life is ≥10 years, and the maintenance cost is low.
