Car bumper automatic robot painting line

A high-quality spray finish is critical to the aesthetics and longevity of your bumper.

Typically, a total of three coats are sprayed: a base coat, a center coat and a top coat. What makes a bumper coating line different compared to other coating programs is its large size. As a result, a lot of space is required for installation/configuration. The paint booth requires a special configuration and the waste paint is discharged via an underground airflow. If the output is high, multiple robotic sprayers are used, thus requiring more space.

Robot spraying system: precise and uniform spraying, automatic adjustment of the spray gun, 360 degrees without dead angle spraying.

Spray pretreatment system

Removing the degrease, dust, rust on the surface of workpiece, and produce a layer Corrosion resistance, adding the adhesion of coating.

Painting system

Manual spraying or automatic with robot or manipulator

Nowadays, robot spraying has become a trend in the development of manufacturing industry. Its advantages are as follows:

A. Robot spraying and transfer system can reduce labor cost and realize industrial automation production.

B. Reduce safety accidents and increase productivity

C. Generally the robot is 6-axis, which is suitable for connecting action with standard related to more than 6-axis to realize difficult and demanding operation.

High temperature curing

Function: Heating the powder which on the surface of workpiece to a regulated temperature and timing, then perform melting, levelling and curing to achieve our required standard.

Heating source system

Function: We are available to supply natural gas, electricity, biologic pellet fuel etc. Based on clients" actual condition.

Quickly improve the temperature efficiency, matched with curing oven which adjustable and stable temperature, to achieve improve the product quality.

Electronic control system

The controller installed nearby the equipment, easily to repair and maintenance, perform a central display, a stable operation.

The equipment available to connect network or utilize 4G telephone card, perform remote data collecting, intelligent monitor, realize industry 4.0. remote equipment maintenance and operation monitor, data transmit by internet, data collecting and related statement prepare by IPC.

Conveyor system

Convey the workpiece to the designated area for each process.

We will design according to workpiece details and clients’ requirements, plate conveyor, floor conveyor, overhead chain conveyor and others for your choice.

Bumper spraying quality requirements are extremely strict, the whole process from pre-treatment, spraying to curing need to be strictly controlled to ensure the quality of bumper coating. Most of the bumper spraying adopts multi-layer wet spraying wet spraying process mode.

The normal workflow is as follows: pretreatment - drying - spraying primer - leveling (drying for 6min) - spraying color paint - leveling - spraying varnish - leveling - drying - cooling - inspection
