Difference between barrel plating line and rack plating line
Author: Robby
Roller plating production line and rack plating production line are two common ways in plating production, they have significant differences in the way of workpiece processing, applicable scenarios, production efficiency and so on. The following is a detailed comparison of them:
1. Workpiece handling method
Roller plating production line:
The workpiece is put into the drum, the drum rotates in the plating solution, and the workpiece rolls inside the drum and finishes plating.
It is suitable for small workpieces (e.g. screws, nuts, small parts, etc.).
Hanging Plating Line:
The workpieces are fixed in the plating tank by the hangers, which are stationary or moving, and the surface of the workpieces is in direct contact with the plating solution.
It is suitable for larger or more complicated workpieces (such as automobile parts, mechanical parts, etc.).
2. Applicable workpiece types
Roller plating production line:
Suitable for small, simple shape and large quantity of workpieces.
It is not suitable for workpieces that are easy to be deformed, easy to be entangled or have high surface requirements.
Hanging plating line:
Suitable for medium and large-sized workpieces with complex shapes and high surface requirements.
Can handle workpieces that require precise positioning or special protection.
3. Production efficiency
Roll plating line:
High production efficiency, can handle a large number of small workpieces at one time.
However, the plating time of a single workpiece is longer, because the workpiece rolls in the drum and the contact time with the plating solution is not uniform.
Hanging plating line:
Relatively low productivity, suitable for small or medium batch production.
But the plating time of single workpiece is shorter and the surface treatment is more uniform.
4. Plating quality
Roll plating production line:
The uniformity of plating layer is poor, and the workpieces may collide with each other, resulting in surface damage or uneven plating layer.
Suitable for workpieces that do not require high surface quality.
Hanging plating production line:
Uniformity of plating layer is good, and the surface of workpiece is not easy to be damaged.
Suitable for workpieces with high requirements on surface quality.
5. Equipment cost
Roll plating line:
Lower equipment cost, suitable for processing small workpieces in large quantity.
Hanging plating production line:
Higher equipment cost, complicated design and maintenance of hangers.
6. Flexibility
Roller plating line:
Lower flexibility, suitable for small standardised workpieces.
Hanging lines:
Higher flexibility, can be customised according to the shape of the workpiece, suitable for diversified production.
7. Application Scenario
Roll plating production line:
Mass production of electronic components, hardware, fasteners and other small workpieces.
Hanging plating production line:
Medium and large-sized workpieces such as automotive parts, household appliances, mechanical parts, etc.
Summary Comparison Table
Characteristics Roller plating line Hanging plating line
Type of workpieces Small, simple workpieces Medium-large, complex workpieces
Production efficiency High (for large batch) Low (for small or medium batch)
Plating quality Poor uniformity, easy surface damage Good uniformity, high surface quality
Equipment cost Lower Higher
Flexibility Lower Higher
Applicable Scenarios Electronic components, hardware, fasteners, etc. Automotive parts, household appliances, mechanical parts, etc.
Suggestion
If you need to process large quantities of small workpieces and do not require high surface quality, choose a barrel plating line.
If you need to process medium-large or complex workpieces and require high surface quality, choose rack plating line.
