Before delving into the details of sheet metal fabrication, it's important to understand one fundamental fact: all sheet metal parts start out flat. Regardless of their final complex shape, the wall thickness of these parts must remain uniform. For example, when designing a series of shelves to house computer equipment, while it might be desirable to thicken the bottom for added strength, this isn't feasible in the world of sheet metal. Unless two pieces of material are welded together (which is possible but adds additional cost), the material's thickness should be consistent throughout.
Furthermore, a wide variety of metals are available, including stainless steel, aluminum, cold-rolled steel, galvanized steel, and even copper and brass, with thicknesses ranging from 0.02 inches to 0.25 inches (depending on the alloy).
One of the most important factors in maintaining consistency is the bend radius. Observe any bent metal bracket or component and note the inside corner radius—this is set by the punch and die on the press brake. Hongsinn can achieve bend radii up to 1 inch, but standard tooling typically produces an inside corner of 0.030 inch, so we recommend sticking to this minimum cost.
The size of the outside corner is greatly influenced by the material thickness and the inside bend radius. Furthermore, the metal's bending resistance must be considered. To prevent cracks and ensure bend tolerances within +/- 1 degree, Hongsinn places bend reliefs at strategic locations. For example, in box-shaped designs, the corners are slightly embossed to ensure proper flange engagement.
In this case, the total bend relief will not exceed the bend radius plus the material thickness, and will not exceed 0.030 inch. This design and treatment ensures the overall strength and functionality of the sheet metal component.
Offset refers to a Z-shaped bend, commonly used in brackets and clips, such as those securing window panes. As with other bends, it's recommended to maintain a consistent radius across all bends, with a preferred radius of 0.030 inches.
Parallel Planes: The distance between parallel planes should be at least twice the material thickness to ensure structural stability.
Tolerance: Hongsinn is able to maintain a tolerance of +/- 0.012 inches to ensure a precise fit between these two features.
Bending a flange completely creates a hem. This hem is designed to reinforce the edge of a part.
This hem is U- or C-shaped and is used to secure the leaf. The inner diameter of the open hem should be equal to or greater than the thickness of the material.
The closed hem is essentially flat and folds completely over the material.
In all cases, the "return length" should be at least four times the material thickness to ensure structural strength and stability.
