Distribution box is used to centralize the installation, distribution and protection of electrical equipment box, is an integral part of the electrical system. This article will introduce the production process of the distribution box in detail to help readers understand the production process and quality control measures of the distribution box.

1. Design phase

before making the distribution box, you first need to work in the design phase:

• determine distribution box purpose and functional requirements;
• design the structure and size of the distribution box according to the requirements of electrical equipment and circuit layout;
• make detailed drawings of the distribution box, including 3D model and floor plan.

2. Material procurement

according to the structure and size of the distribution box determined in the design drawings, material procurement is carried out:

• choose to meet the requirements of the metal plate, generally galvanized steel plate or stainless steel plate;
• procurement of electrical components, such as circuit breakers, contactors, relays, etc;
• prepare other accessories and auxiliary materials.

3. Material pretreatment

before making the distribution box, the material needs to be pretreated:

• cutting and forming the metal plate, making the box and door panel of the distribution box according to the design requirements;
• surface treatment, such as spraying anti-rust paint or galvanizing, to increase the corrosion resistance of the metal plate.

4. Assembly welding

assembly welding of pretreated sheet metal:

• assemble the box body and the door panel according to the design drawings, and fix them by welding or bolting;
• for fillet welding, butt welding and other welding processes, to ensure that the joint is firm, good sealing.

5. Installation of electrical components

installation of electrical components inside the distribution box:

• according to the design requirements, the installation of circuit breakers, contactors, relays and other electrical components;
• connect electrical lines, carry out wiring and wiring work, and ensure the normal operation of electrical components.

6. Assembly inspection

after completing the assembly of the distribution box and the installation of the electrical components, carry out assembly inspection:

• check the appearance quality and dimensional accuracy of the distribution box to ensure that it meets the design requirements;
• electrical test to check whether the connection of electrical components is correct and whether the function is normal.

7. Quality Control

in the entire production process, strict quality control is required:

• inspection of raw materials to ensure compliance with requirements;
• quality control in each production link to avoid quality problems;
• finished product testing to ensure that the quality and performance of the distribution box meet the standard requirements.

8. Packaging factory

after the quality inspection of qualified distribution box for packaging factory:

• use appropriate packaging materials to protect the distribution box from damage;
• mark the product model, specifications, production date and other information, easy to use and management.

The production process of the distribution box includes design, material procurement, material pretreatment, assembly and welding, installation of electrical components, assembly testing, quality control and packaging factory. By strictly implementing the process flow and quality control measures, it can ensure that the quality and performance of the distribution box meet the requirements, and improve the reliability and safety of the product.
