High-Difficulty Roll Forming Stamping Process for Stainless Steel Brackets

The core manufacturing process of this product is roll forming, which is considered one of the more technically demanding operations in metal stamping. Shih Yeh roll-forms 2 mm thick stainless steel sheet into a large-diameter cylindrical structure exceeding 60 mm, requiring precise control of forming accuracy and roundness consistency. This process places high demands on die design, forming sequence planning, and press force control, making it a key factor in achieving stable and repeatable mass production.

Tight Dimensional Tolerance Control by Managing Stainless Steel Springback

Stainless steel materials are prone to springback after forming, and this effect becomes more pronounced at a thickness of 2 mm, significantly increasing the difficulty of dimensional control during roll forming. At the die design stage, Shih Yeh incorporates material springback coefficients into the tooling design and process planning. Through precise die engineering and optimized forming conditions, springback effects are effectively suppressed, allowing critical post-forming dimensions—such as diameter and roundness—to be consistently controlled within drawing-specified tolerances. This ensures high consistency and long-term reliability during actual assembly and extended service life.

Dedicated Jigs and Gauges for Hole Position and Center Distance Accuracy

The mounting holes on the two bent side legs of the bracket must maintain a specified distance from the center of the rolled cylindrical structure, requiring strict positional accuracy. To meet this requirement, Shih Yeh develops dedicated fastening jigs and inspection gauges to control hole location and center distance throughout both manufacturing and inspection stages. This ensures that every component meets the assembly and functional requirements of marine fuel pump systems.

Manufacturing Capability and Application Scope

This type of stainless steel roll formed metal stamping component is suitable for applications involving medium-to-thick sheet metal forming, high structural strength requirements, and strict demands on roundness, dimensional stability, and hole position accuracy. It is particularly well suited for system-level components operating under long service hours, continuous vibration environments, and mass production conditions where consistency is critical. Actual structural designs, dimensions, and tolerance specifications are evaluated based on customer drawings and application requirements to ensure manufacturing feasibility.

For marine fuel systems, consistency in component dimensions and hole positioning directly affects fuel pump assembly stability and overall system reliability. Through stable roll forming control and precise hole positioning mechanisms, assembly variation and downstream maintenance risks are reduced, meeting the marine industry’s requirements for long-term operational safety and durability.
