Adaptable to various hinge types, including butt hinges, piano hinges, and custom designs, the hinge punch and die set caters to a wide range of applications in multiple industries.

Offset Punch and Die

The offset punch features a unique profile that allows it to create bends with an offset in the material. With two bending surfaces at different heights, it enables the precise formation of offsets, which are essential in certain fabrication processes.

Paired with an offset die, which has corresponding steps or grooves, this tooling ensures consistent, accurate bending. The die supports the material during the process, helping achieve the desired angles and offsets, making this tool indispensable in applications requiring precision and uniformity.

Adjustable Bending Die

The adjustable bending die stands out for its ability to change the V-opening width, allowing it to accommodate a range of material thicknesses. This flexibility makes it suitable for various bending tasks, from thin sheets to thicker plates, enhancing its versatility in a production environment.

Some designs also allow for fine-tuning of the bending angle, providing precise control over the bend without the need to switch out the die. This capability is especially beneficial in scenarios requiring multiple bends with different angles, making the adjustable bending die a critical tool for efficiency and precision in metalworking.

Radius Tool for Bending in PU-Insert

The radius tool for bending with a PU-insert is designed to minimize material damage during bending operations. The Polyurethane insert provides a softer contact surface, which is particularly important when working with coated, polished, or delicate materials that are prone to surface damage.

This tool is versatile, allowing for the creation of bends with consistent radii, which can be adjusted according to the specific tool design. Suitable for a wide range of materials, including stainless steel and aluminum, the PU-insert tool is essential for achieving accurate bends without compromising material integrity.

Swing Ear Sections Punch

Swing ear sections are a valuable addition to box bending setups, simplifying and accelerating the bending process. These sections swing out of the way once bending is complete, allowing for the easy removal of the finished part and reducing the risk of damage during removal.

The design of swing ear sections enhances efficiency in box bending, making the process quicker and more reliable. By facilitating the easy removal of the part, these sections ensure that the final product is free from defects caused by handling, making them a must-have for precision box bending operations.

No Indentation Die

The no indentation die, also known as a non-marking die, is engineered to prevent marks or indentations on the workpiece during bending. This is particularly important when working with soft or coated metals like aluminum, copper, or pre-painted steel, where traditional dies might damage the surface.

Using a no indentation die reduces the need for additional finishing processes such as polishing or buffing, which are often required to remove marks left by standard dies. This not only improves production efficiency but also lowers costs associated with rework and material waste, making it a valuable tool in metalworking.

Rib Punch and Die

The rib punch and die set is specifically designed for creating ribs or stiffening features in sheet metal. The punch presses into the metal, forming the rib, while the die provides the corresponding cavity or groove that shapes the metal into the desired profile.

These tools are essential in industries like automotive and aerospace, where adding ribs to large panels improves load-bearing capacity and resistance to deformation. By enhancing the structural integrity of components, rib punches and dies play a crucial role in the production of durable, high-performance products.

Hemming Punch and Die

A hemming punch and die set is used to create hems in sheet metal, which are folds at the edges of parts. This process strengthens the edges, improves appearance, and eliminates sharp edges, making the components safer to handle.

Hemming is a common process in the automotive industry, where it is used to fold the edges of doors, hoods, and trunk lids. The hemming punch and die ensure tight, clean fits for body panels, contributing to the overall quality and finish of the final product.

Radius Punch and Die

The radius punch and die set is designed to create bends with a specific radius, providing a smooth, rounded edge rather than a sharp corner. This type of bend is important for maintaining the structural integrity of the material and achieving a more aesthetically pleasing finish.

Commonly used in industries like automotive, aerospace, and appliance manufacturing, radius bends help distribute stress more evenly across the material. This reduces the risk of cracks or fractures, making the component stronger and more durable, which is essential for high-quality metal fabrication.

Standard Punch Tool

The standard punch tool is primarily used for air bending, a versatile and widely used bending method. Typically, a standard punch and die set consists of a punch (upper tool) and a die (lower tool) that work together to bend sheet metal.

The 86-degree punch is slightly less than 90 degrees, accounting for springback, which is the tendency of the metal to return to its original shape after bending. This design ensures that the resulting bend is closer to the desired 90 degrees after springback occurs, making it a reliable tool for achieving precise bends.

U-Bending Tools

U-bending tools are specifically designed to create U-shaped profiles in sheet metal, which have a flat bottom and vertical sides. The U-punch has a profile that corresponds to the interior of the U-shape, while the U-die features a groove or channel that matches the outer profile.

These tools are commonly used to produce channels and brackets, which are essential in construction, framing, and structural applications. The precise fit between the punch and die ensures accurate, consistent bends, making U-bending tools indispensable for producing high-quality components.

Louver Punch and Die

A louver punch and die set is used to create louvers in sheet metal, which are slotted openings typically used for ventilation, heat dissipation, or aesthetic purposes. The louvers are raised at an angle from the material, forming a tent-like structure.

Louvers are commonly used in HVAC systems, electrical enclosures, and other applications where air circulation is important. The louver punch and die set ensures that these openings are formed cleanly and consistently, maintaining the structural integrity of the material while providing the necessary functionality.
