JS company adopts a vacuum adsorption platform to fix sheet metal, with high precision rolling equipment for pretreatment, eliminating wavy deformation of sheet metal, ensuring that the surface of the cut is less than 0.02mm/m² of the flatness error.

2.Surface cleaning and oxide layer control

Ultrasonic cleaning is used to remove oil stains and impurities before cutting to prevent slag adhesion from affecting accuracy. For materials with high reflectivity, such as aluminum alloys, a special coating is used to reduce reflectivity.

Quality inspection and feedback mechanism

1.Online detection system

Integrated laser displacement sensor and CCD camera, real-time monitoring of cutting edge quality, automatic removal of defective products, proposed process optimization.

JS Company's Quality Control Process

• Samples from 3D contour scanner are provided to compare the deviation values between the design model and the actual cutting parts, and a detailed accuracy analysis is published (for example, an aeronautical aviation component the flatness error of only 0.003mm in the case of a customer).
• Establish a three-level quality inspection system for order repetition, including first inspection, process inspection and finished product inspection to ensure batch consistency.

Environmental and sustainable development control

The influence of ambient temperature and humidity changes on material size stability is reduced through constant temperature and humidity workshops (temperature ±2°C, humidity 40-60% RH).

My company reminds you that its green manufacturing processes, such as waste recycling system, not only reduce energy consumption, but also indirectly improve processing accuracy by reducing material waste (material utilization rate increases to over 92%).

Can carbon steel and aluminum steel metal be directly welded?

In sheet metal fabrication, the direct welding of stainless steel and aluminum plates faces great challenges, mainly due to their different physical and chemical properties:

Difficulties with direct welding

1.Formation intermetallic compounds

When stainless steel (e.g. 304, 316) comes into contact with aluminum (e.g. 1060, 5052) at high temperatures, iron reacts with aluminum to form brittle intermetallic compounds, leading to lower weld strength and even cracking.

2.Differences in thermal expansion coefficients

The thermal expansion coefficient of aluminium (about 23×10-6°C) is 1.4 times that of stainless steel (about 17×10-6°C) and is prone to deformation or cracking during welding due to thermal stress.

3.Differences in melting point and thermal conductivity

The melting point of aluminum (660 °C) is much lower than that of stainless steel (1375-1530 °C), and aluminum has a the thermal conductivity three times that of steel, which results in rapid heat loss during welding and makes it difficult to maintain the stability of the melting pool.

Feasible processes and limitations

1.Traditional arc welding (e.g. TIG/MIG)

• Feasibility: Special welding wire (e.g. ER4043 Al Si) are required and protective gases (argon+helium mixed gas) are added, but the weld strength is relatively low (only 50-70% of the base metal).
• Constraints: Porosity and slag inclusion are easily generated, and intermetallic compounds may expand during long-term use, leading to failure.

2.Brazing or diffusion welding

• Brazing: Low temperature brazing materials (e.g. Al-Si series) are used to fill gaps through capillary action, avoiding direct melting of the substrate, but joint strength is limited (usually<150MPa).
• Diffusion welding: It requires vacuum or inert gas environment to connect atoms horizontally at high temperature and pressure.

3.Recommendations for alternative solutions

If a high intensity connection is required, the following methods are recommended:

• Mechanical connection: use riveting, bolt connection or buckle structure to avoid problems in heated areas, suitable for automobile and electronic equipment housing.
• Adhesive+mechanical composite: Combine epoxy resin adhesive with spot welding to balance sealing and strength.

How to select sheet metal thickness based on the sheet metal gauge chart?

1.Clarify application scenarios and functional requirements

Determine the required sheet metal thickness range according to the load bearing requirements, usage environment and assembly method of the member. For example:

• Lightweight components (electronic case): Preference should be given to thin plates (corresponding gauges 20-24, thickness 0.5-0.8mm).
• Structural support (mechanical brace): Medium thick plates (specifications 10-14, thickness 1.0-1.6mm) are required.

2.Match material type and thickness range

The thickness of different materials varies widely, and the mechanical properties need to be selected:

3.Reference process compatibility verification thickness

To ensure that the thickness matches the process parameters for the limitations of the processing process:

4.Compare tolerance standards with cost balances

Select the optimal optimal specification according to industry standards (ISO 2768) and cost requirements:

Using the sheet metal gauge chart, can quickly locate material specifications, optimize bending radius, laser power and other technological parameters, balance strength, cost and processing feasibility. For example:

• Sheet metal (Gauges 20-24): Low cost but limited strength, suitable for decorative parts.
• Medium Plate (Gauge 12-18): Strong universality, covering 80% of industrial scenes.
• Heavy plate (Gauge ≤10): High cost for heavy equipment but outstanding bearing capacity.

2.Material utilization optimization: Through the simulation of the 3D laser cutting path, the waste of angular material is reduced and the comprehensive utilization rate of materials is increased to over 92%.

Summary

In sheet metal fabrication, the choice of materials and processing technology directly affects the performance and service life of the final product. galvanized steel sheet, for example, has become one of the most widely used materials due to its advantages of rust prevention, economy and ease of processing, especially in structural components that require corrosion resistance. However, in bending sheet metal  process, special attention should be paid to the protection of zinc layer, to avoid excessive bending or improper processing resulting in coating damage, thus weakening the durability of the material. With the development of technology, modern sheet metal manufacturing is developing in the direction of high precision, lightweight and sustainable, while taking into account material properties and processing efficiency, while also meeting environmental challenges.
