The main reasons for the high price of electrical enclosures include material cost, processing difficulty, market demand, and certification standards.
First of all, this kind of enclosure is generally used in industries such as industry and medical treatment, so it involves customization. Once customization is involved, it will lead to an increase in various costs. The production of non-standard products has always been more expensive than standard products. This is a fact. In addition, material cost is also one of the important factors affecting the price of electrical enclosures. Take the all-aluminum chassis as an example. Although aluminum is an abundant metal on the earth, its extraction cost is high, especially the cost of producing aluminum by electrolysis. In addition, all-aluminum chassis usually use aluminum alloys instead of pure aluminum, because pure aluminum is easy to oxidize and affect the appearance. Aluminum alloys need to be added with other metal materials to achieve the required strength, which makes the cost of aluminum alloys relatively high. Of course, in addition to material costs, there are 3 other reasons. The following are specific analysis and suggestions for optimizing costs:
1. High material cost
Metal materials: Most electrical enclosures use steel, aluminum alloys or stainless steel. The prices of these materials are affected by international market fluctuations (such as iron ore and aluminum ore prices).
Special processing requirements: Anti-corrosion, explosion-proof, fire-proof and other requirements require additional coatings (such as galvanizing, plastic spraying) or the use of stainless steel, which increases costs.
Insulation materials: The housing of high-voltage equipment needs to be added with engineering plastics (such as polycarbonate) or epoxy resin, and the material cost is higher.
2. Complex manufacturing process
Precision machining: The housing needs to meet strict dimensional tolerances (such as IP protection level), and requires precision processes such as laser cutting and bending.
Welding and assembly: Explosion-proof cabinets require seamless welding processes, and labor and equipment costs are high.
Testing and certification: It is necessary to pass international certifications such as UL, IEC, and CE, and the testing fee accounts for 10%-20% of the cost.
3. Customized requirements
Non-standard design: In industrial scenarios, the housing often requires customized size, openings, and heat dissipation structures, which makes it impossible to mass produce.
Functional integration: High-end housings integrate cooling fans, EMI shielding, seismic structures, etc., with high technical added value.
4. Strict industry standards
Safety requirements: For example, explosion-proof cabinets must comply with ATEX/IECEx standards, and the materials must be resistant to high temperatures and impacts.
Environmental adaptability: Outdoor enclosures must meet IP65/IP67 protection levels, and sealing materials and process costs are high.
5. Supply chain and market factors
Transportation and tariffs: Metal materials are large in size and heavy in weight, and cross-border transportation costs can account for 15%-30%.
Of course, the high cost of electrical enclosures is mainly driven by materials, processes and industry standards. If you need to reduce costs, you can give priority to standardized products or lightweight designs, and at the same time evaluate whether the actual needs match high-end functions. For customized scenarios, in addition, for batch customization needs, it is recommended to negotiate a tiered quotation with the sheet metal manufacturer (the larger the batch, the lower the unit price). If you need to customize electrical enclosures in large quantities, you can choose China Mulan Group, which is a professional sheet metal manufacturing company in China that can customize various sheet metal parts, such as chassis cabinet, housings, brackets, Covering medical, industrial, construction, electronics and other industries, the sheet metal products produced each year are shipped to more than 30 countries and regions around the world.
