Application case of semi-automatic powder spraying line for aluminum profiles
Project Background
A certain aluminum profile processing enterprise mainly produces industrial profiles for building doors and windows. The original manual spray painting process of the enterprise can no longer meet the production needs of high efficiency, environmental protection, and high quality. Therefore, the company has decided to introduce a semi-automatic electrostatic powder coating production line to enhance its surface treatment capabilities.
Solution
Based on the factory conditions, daily production capacity (about 2-5 tons), and the production characteristics of multiple varieties and small batches, a set of horizontal semi-automatic electrostatic powder spraying lines has been customized for the enterprise.
Main process flow
· Loading: Manually suspend the workpiece on the conveyor system
· Automatic spraying:Two reciprocating automatic spray gun systems with automatic elevators are used to evenly spray according to the profile contour.
· Manual spraying:Two workers use manual spray guns for supplementary spraying to ensure no blind spots are covered.
· Powder recycling: The powder spraying room is equipped with a recycling system to collect and recycle unadsorbed powder, with a powder utilization rate of over 97%.
· High temperature curing:The sprayed profile is manually pushed into the curing oven. Bake at a temperature of 180-200 ℃ for 15-20 minutes to melt, level, and solidify the powder, forming a dense and smooth protective layer.
· Cooling unloading:Natural cooling followed by manual unloading and inspection
Project Results
· Significant efficiency improvement: Compared to traditional manual painting, production efficiency has increased by more than 50%
· Excellent coating quality:Electrostatic spraying ensures that the appearance quality of the product meets the industry’s high standards.
· Significant cost reduction: The powder has a high utilization rate and can be recycled, reducing raw material waste.
· Environmental and safety standards: The powder recycling system effectively controls dust pollution and improves the working environment in the workshop.
· Strong flexibility: Especially suitable for the production of multiple varieties and small batches of orders, with convenient and fast color and type changes.
Summary
The successful application of this semi-automatic powder spraying line significantly enhances the added value and market competitiveness of the product.
