1.Raw Material Preparation

Material Selection: Select suitable raw materials based on the purpose and performance requirements of the corner bracket, such as galvanized steel sheets, aluminum alloy profiles, zinc alloys, etc.

Material Inspection: Inspect the dimensions, thickness, material composition, and surface quality of the raw materials to ensure they meet production standards and avoid using defective materials that could affect product quality.

Material Pretreatment: For metal sheets, leveling may be necessary to eliminate bending and deformation; for aluminum alloy profiles, sawing may be required to cut them to the appropriate length for subsequent processing.

2.Blanking

Shearing/Cutting: According to the design drawings, use equipment such as shearing machines, laser cutting machines, and plasma cutting machines to cut the raw materials into the required blank shapes and sizes.

Stamping Blanking: For corner brackets produced in batches, a stamping process can be used. Using a punch press and molds, the blank is stamped off the sheet material in one go, simultaneously stamping the holes, improving production efficiency.

3.Forming Processing

Bending: Use a bending machine or punch press to bend the blank into the required shapes such as L-shapes and U-shapes according to the design requirements. When bending, it is important to control the bending angle, bending radius, and springback to ensure product dimensional accuracy.

Stamping: For corner brackets with complex shapes, multiple stamping processes can be used to gradually stamp the blank into the required shape, such as protrusions, grooves, and reinforcing ribs.

Die Casting: For corner brackets made of materials such as zinc alloy, die casting can be used. Molten metal is poured into a mold, and after cooling, it forms the desired shape. Die casting has advantages such as high production efficiency, high product precision, and good surface quality.

CNC Machining: For corner brackets with high precision and complex shapes, CNC milling machines, CNC lathes, and other equipment can be used for machining. The movement of the cutting tools is controlled by programming to achieve precise machining of the blank.

4.Surface Treatment

Deburring: Use equipment such as grinders, belt sanders, and vibratory grinders to remove burrs and sharp edges from the surface of the corner brackets to prevent scratches and affect assembly accuracy.

Cleaning: Ultrasonic cleaning and spray cleaning are used to remove oil, dust, and impurities from the surface of the corner brackets, preparing them for subsequent surface treatment.

5.Surface Coating

Zinc Plating: A zinc layer is formed on the surface of the corner brackets through hot-dip galvanizing or electro-galvanizing processes, improving their corrosion resistance.

Powder Coating: The bracket surface is powder-coated or painted. Different colors and coating thicknesses can be selected according to customer needs, enhancing the product's aesthetics and protective performance.

Anodizing: For aluminum alloy corner brackets, anodizing treatment can be performed to form an oxide film on the surface, improving its hardness, wear resistance, and corrosion resistance.

Sandblasting: Sandblasting gives the corner bracket surface a uniform roughness, enhancing coating adhesion and improving the product's appearance.

6.Assembly

Component Assembly: For some modular corner brackets, multiple components need to be assembled, such as mounting screws, nuts, and plastic parts, ensuring a secure and precise assembly.

Welding: For steel structure corner brackets, welding may be required to weld different components together to form a whole. During welding, it is crucial to control welding quality to avoid defects such as porosity, cracks, and slag inclusions.

7.Quality Inspection

Dimensional Inspection: Use calipers, micrometers, protractors, projectors, and other equipment to inspect the dimensions, angles, and hole positions of the corner brackets to ensure they meet design requirements.

Appearance Inspection: Inspect the surface quality of the corner brackets, checking for even coatings, scratches, burrs, bubbles, and other defects.

Performance Testing: Conduct appropriate performance tests based on the product's application and requirements, such as tensile strength testing, compressive strength testing, and corrosion resistance testing, to ensure product performance meets standards.

8.Packaging and Warehousing

Packaging: Pack the qualified corner brackets using cardboard boxes, plastic bags, bubble wrap, and other packaging materials to prevent damage during transportation.

Warehousing: Store the packaged products in the warehouse and manage inventory for subsequent sales and shipments.
