In the process of industrial equipment transforming towards intelligence and precision, the stable support of sheet metal racks, the safe protection of sheet metal enclosures, and the precise connection of sheet metal accessories have all become key factors for the efficient operation of equipment. With our professional sheet metal processing capabilities, we provide solutions for metal accessories and mechanical parts for various industrial scenarios, with precision manufacturing.sheet metal rackssheet metal rackssheet metal rackssheet metal rackssheet metal rackssheet metal rackssheet metal rackssheet metal enclosuressheet metal enclosuressheet metal enclosuressheet metal enclosuressheet metal enclosuressheet metal enclosures
Material Selection: The rack is made of Q355B low - alloy high - strength steel, and flaw detection is carried out to ensure no internal defects; the enclosure is made of 1.5mm thick galvanized steel sheet, and the electromagnetic shielding effect is enhanced through surface conductive oxidation treatment.
Process Optimization: Robot automatic welding is used for rack welding to reduce manual operation errors, and stress relief treatment is carried out after welding; CNC bending machine is used for enclosure bending, and special molds are used to achieve precise 90° angle forming, with the gap controlled within 0.1mm.
Accessory Adaptation: The connecting pieces in the sheet metal accessories are cut by laser to ensure perfect alignment of the holes with the rack and enclosure; the guide wheel shafts in the mechanical parts are precision ground, with a surface roughness of Ra0.8μm, reducing operating noise.
II. Full - Process Quality Control: Safeguarding Product Reliability
Pre - production Inspection: Mechanical property tests (such as tensile strength and yield strength) are carried out on raw materials. The measured tensile strength of Q355B steel plate reaches 520MPa, far exceeding the project requirement of 490MPa.
In - process Inspection: Quality inspection nodes are set up for each process. For example, after rack welding, a coordinate measuring machine is used to detect key dimensions; after enclosure assembly, electromagnetic shielding effectiveness test is carried out (the measured shielding effectiveness is ≥80dB, meeting industrial standards).
Factory Verification: Full - load tests are conducted on finished products. The rack is placed under 120% rated load for 48 hours, with a deformation of only 0.3mm, far lower than the allowed limit of 1mm; the supporting metal accessories undergo a 48 - hour salt spray test without rust, meeting the durability requirements of the warehousing environment.
The three - dimensional shelves supported by sheet metal racks run stably, and with the automated stacker, they realize high - speed storage and retrieval of goods. The daily processing capacity is increased to 8000 boxes, which is 50% higher than that of the traditional shelf system.
The sheet metal enclosures effectively isolate electromagnetic interference in the warehouse, reducing the failure rate of the control system by 70% and ensuring the continuous operation of the equipment.
The precision sheet metal accessories and mechanical parts reduce vibration and wear during equipment operation, and the expected service life is extended to more than 10 years, reducing the maintenance cost of customers.
