Advantages | 1. The structure of transportation chain is simple and easy to maintain; 2. Hanger pitch can be flexibly adjusted according to the length of aluminum profiles | The transporter consists of a traction track and a load-bearing track, which can branch, detach, transfer and store aluminum profiles, thus, making the curing oven, loading and unloading areas have a large footprint. | Biplane transporter running up and down the circuit, the equipment is divided into upper and lower two layers of configuration, occupies a small area of land, the unit area of high yield | 1. Pretreatment-powder spraying-curing in one, high degree of automation, in the case of the same chain speed and covers an area of roughly the same, the output is 4-5 times that of the horizontal line; 2. Good liquid dripping of pre-treatment, less chemical and water consumption; 3. In the spray booth, the aluminum profile can be rotated by 4×90°. |
Disadvantages | 1. Large floor space, low output per unit area; 2. Long curing oven, high energy consumption per unit output; 3. It is difficult to set up a continuous production line with the pre-treatment group, requiring more production workers; 4. large film thickness difference of aluminum profiles, generally up to ± 20μm; 5. Higher operating costs due to higher energy consumption, chemical consumption, powder consumption and labor consumption. | 1. Requires a high level of maintenance for the transporter. 2. It is difficult to set up a continuous production line with the pre-treatment group, requiring more production workers; 3. large film thickness difference of aluminum profiles, generally up to ± 20μm; 4. Higher operating costs due to higher energy consumption, chemical consumption, powder consumption and labor consumption. | Low annual output | 1. Large initial investment in equipment; 2. Requires better management |
