1、 Overview of Metal Spray Coating Process Flow
 
The spraying process of hardware mainly includes the following steps: pre-treatment, spraying, drying, inspection, and packaging. Specifically, it includes the following:
 
1. Pre treatment mainly involves cleaning, degreasing, and rust removal of hardware components to facilitate better adhesion of sprayed coatings to the surface of the hardware components;
 
2. Spraying is the process of evenly applying paint onto the surface of hardware components to form a protective film;
 
3. Drying is the process of placing sprayed hardware into an oven and heating it to rapidly solidify the coating, thereby improving its wear resistance and corrosion resistance;
 
4. Inspection is a quality check of the sprayed hardware to ensure that its surface is smooth and free of defects;
 
5. Package qualified hardware components for transportation and use.
 
2、 How to choose the appropriate hardware spraying process?
 
1. Choose coatings based on the material and purpose of the hardware: Different materials and purposes of the hardware require different coatings, such as epoxy resin coatings for stainless steel hardware and aluminum alloys
 
Hardware can be coated with polyurethane paint, etc.
 
2. Choose spraying equipment based on the size and shape of the hardware: The selection of spraying equipment should be determined based on the size and shape of the hardware to ensure that the coating can be evenly sprayed on the hardware
 
On the surface.
 
3. Choose the process flow according to the production scale and cost requirements: In the case of a large production scale, a fully automatic spraying production line can be selected to improve production efficiency and reduce costs; Born
 
For small-scale production, semi-automatic or manual spraying production lines can be chosen.
