Mobile shelving production process

What are the general requirements for the manufacturing process of mobile filing cabinets ?

Mobile shelving is made by applying years of experience in mechanical products and machine tool manufacturing, including design methods, technical requirements, production processes, and quality management, to the production of mobile shelving. Sheet metal processing is all done using molds, and the transmission mechanism is produced in accordance with machine tool manufacturing process requirements.

How do manufacturers of mobile shelving units test whether their workmanship is up to standard?

The factory implements a "dual three-level inspection system," namely, first-piece inspection, batch inspection, final assembly inspection, and self-inspection by production workers, batch inspection in the workshop, and sampling inspection by the factory's general inspection department. It also widely adopts the international quality certification ISO9002 inspection standard for production control and product quality management.

What are the surface treatment processes used by mobile filing cabinet manufacturers ?

The product surface treatment adopts electrostatic powder spraying process, and the anti-corrosion treatment before spraying is strictly carried out in accordance with the national standard JB6807 "Technical Conditions for Phosphating of Steel Workpieces Before Painting".

What are the manufacturing processes for mobile filing cabinet manufacturers?

The manufacturing process of mobile filing cabinets is as follows:

The process is as follows: shaped and welded workpiece → alkaline washing to remove oil → water washing → acid washing to remove rust → light neutralization → water washing → alkaline neutralization → water washing → activation treatment → water washing → phosphating 1 → phosphating 2 → water washing → passivation → water washing → drying.

What standards do mobile shelving manufacturers in Huadu follow for their spraying process?

The products undergo electrostatic powder coating, which is carried out on two fully automated electrostatic powder coating production lines. The coating quality strictly adheres to the requirements of GB/TB667163.

Steel processing for mobile storage cabinets

I. Surface degreasing and rust removal process

① After the oil stains, rust spots and oxide layers on the surface of the workpiece are removed and degreased by chemical methods, there are no grease, floating turbid liquid or other contaminants, and the surface is completely wetted with water.

② After pickling, the workpiece does not show any visible corrosion phenomena such as oxides or rust spots, and its surface color is basically uniform.

II. Surface Phosphating Process

① Phosphating is mainly carried out by impregnation.

② Phosphating treatment uses zinc-calcium dihydrogen phosphate as the main component of the solution. The phosphating bath solution is prepared and adjusted according to the process specifications.

③ After phosphating, the workpiece is thoroughly cleaned with running water to improve the cleaning quality of the working surface, and hot complexing acid solution is used for sealing treatment.

④ After phosphating and washing, the workpiece is dried in a dryer before it can be powder coated.

⑤ The time interval between phosphating and powder coating of the workpiece shall not exceed 24 hours.

III. Appearance of the phosphating film on the surface

① The workpiece is gray after phosphating, and the film layer is dense, continuous and uniform.

② The thickness of the film layer is generally controlled at 5 mm.

③ Surface inspection of phosphating: Use a test solution to observe the droplet changing from sky blue to pale yellow or pale red, and ensuring it does not change color within a specified time. Finished products are then put into storage and proceed to the powder coating process.

The mobile shelving units are made of high-quality cold-rolled and hot-rolled steel plates, molded and formed. The surface undergoes ten pre-treatment processes, including degreasing and rust removal. The latest internationally popular matte electrostatic powder-coated mobile shelving units are formed through high-temperature plasticizing, offering excellent rust resistance. The Huadu mobile shelving units feature a beautifully designed frame with smooth lines, making the warehouse neat and aesthetically pleasing. Operation is easy and flexible, and operation is stable. The shelving units adopt a modular assembly design, ensuring no damage during relocation and disassembly. Each row of shelves is equipped with safety limiters and anti-tipping devices to ensure the safety of personnel in the aisles. The side frames are equipped with locks for overall locking. Contact surfaces between the shelving units have cushioning and magnetic sealing strips. The top has a dustproof panel, and the bottom has a rodent-proof device. It has excellent dustproof, rodent-proof, moisture-proof, and fireproof functions. The transmission mechanism uses precision bearings, ensuring flexible and smooth transmission. Shelf spacing can be freely adjusted as needed.

Cost accounting for mobile mobile shelving

What are the components of the cost of mobile filing cabinets ?

The cost of mobile shelving units consists of material costs, labor costs, and adjustment fees.

How do the material costs of mobile shelving units affect their price?

Material cost refers to the base material used in mobile shelving units. Thicker and higher-quality boards result in higher costs.

What constitutes the labor cost within the overall cost of mobile shelving units ?

Wages are the cost for workers to produce a set of mobile shelving units. Because labor costs vary between different manufacturers of different sizes, wages will also differ.

What other adjustments are included in the price cost of mobile filing cabinets ?

The adjustment fee includes: freight, handling, installation, food and accommodation, taxes, etc.

How to determine the final cost quote for mobile filing cabinets ?

To understand the cost of mobile mobile shelving, you need to consider the above points. Typically, the purchase cost of a standard mobile mobile shelving unit is 1150-1350 yuan per set. The cost is affected by the number of units in a row and the quantity purchased at one time. Additionally, if a manufacturer offers an extremely low price, they will ultimately recoup the cost through material and adjustment fees. Therefore, when researching and purchasing mobile mobile shelving, it's important to compare prices and ask questions.
