Product Description

Bending This vital step in sheet metal fabrication enables the creation of intricate forms such as V-shapes, U-shapes, and other complex geometries by artfully deforming metal along a straight axis.
Post-Bending Finishes
Deburring: Achieved through vibratory tumbling or meticulous manual filing to ensure a polished finish.
Surface Treatment: Options include powder coating for durability, anodizing for corrosion resistance, and plating for a sleek finish.
Inspection: Utilize advanced laser scanning or Coordinate Measuring Machine (CMM) for precision assessment on critical parts.

Stamping This process is the backbone of high-volume manufacturing, employing precise dies and powerful presses to expertly cut, bend, or shape sheet metal into desired configurations.
Post-Stamping Processes
Deburring: Techniques include vibratory tumbling, grinding, or innovative laser deburring for a flawless finish.
Surface Finishing: Choose from powder coating for protection, electroplating for conductivity, or anodizing for enhanced surface resilience.
Inspection: Implement vision systems, CMM, or manual checks to ensure the highest quality and accuracy.

Laser cutting This high-precision, non-contact thermal process employs a focused laser beam to meticulously cut, engrave, or perforate sheet metal with unparalleled accuracy.
Post-Processing
Deburring: Achieved through vibratory tumbling, manual filing, or laser deburring for a smooth edge.
Edge Smoothing: Techniques include grinding or electropolishing, particularly effective for stainless steel, ensuring a refined finish.
Surface Coating: Options like powder coating, anodizing for aluminum, or plating, provide aesthetic appeal and protective benefits.

Design Guidelines
Holes/Slots: Positioning should be at least 2×T from the bend line to prevent unwanted distortion during fabrication.
Bend Sequence: Initiate with the furthest bend to avoid collisions, ensuring smooth production flow.
Relief Cuts: Essential for facilitating adjacent bends or maintaining tight tolerances with precision.
Spring back Compensation: Implement overbending by 2°-5°, adjusting for material variability to achieve the desired angle.

Key Parameters in Bending
Bend Radius: Typically recommended to be 0.5-1.5 times the material thickness to prevent cracking and ensure structural integrity.
K-Factor: This ratio of the neutral axis to material thickness is crucial as it determines the bend allowance and ensures accuracy.
Bend Allowance/Deduction: Essential for calculating the flat pattern length prior to bending, offering precision in metal fabrication.
Spring back: This refers to the elastic recovery post-bending, which is skillfully accounted for by over bending, ensuring the final form matches specifications.
