Our Metal Stamping Process Technologies:
Tool and Die Design: The design and engineering of precision tooling and dies are essential for metal stamping operations. These tools are customized to the specific part design and enable the shaping and cutting of the metal sheets.
Blanking: Blanking is the process of cutting the metal sheet into the desired shape using a die and a punch. This step removes the excess material from the sheet and prepares it for further forming operations.
Bending: Bending is the process of deforming the metal sheet using a punch and die to create angles, curves, or complex shapes. It requires precise control of the bending force, angle, and depth to achieve the desired shape.
Forming: Forming involves shaping the metal sheet using a combination of punches, dies, and other tools to create features such as embossing, ribbing, or flanging. It allows for the creation of intricate and functional designs.
Piercing: Piercing is the process of creating holes or openings in the metal sheet using a punch and die. This can be done to accommodate fasteners, ventilation, or other functional requirements.
Coining: Coining is a precision forming process that applies high pressure to the metal sheet to create tight tolerances, smooth surfaces, and sharp edges. It is often used to achieve high-quality finishes and precise dimensional control.
Assembly: Metal stampings may require additional assembly processes such as welding, riveting, or fastening to join multiple stamped components together or to other parts.
These various process technologies are combined and customized based on the specific requirements of the metal stamping project to achieve the desired shape, dimensions, and functionality of the final stamped component.
Sheet Metal Design Guidelines
During the metal stamping design process, it's essential to consider the following guidelines:
Holes: The hole diameter should be at least 1.2 times the material thickness. For high-tensile materials like stainless steel alloys, the minimum hole diameter should be at least two times the material thickness.
Edge to Holes: Maintain a distance of two stock thicknesses between holes and the edge. For oblong holes shorter than 10 material thicknesses, the edge-to-hole spacing should be two times the material thickness. For longer oblong holes, the spacing should be four times the material thickness or more to avoid bulging.
Hole to Form: To prevent hole deformation when forming a bend close to a hole, the spacing should be the bend radius plus 2.5 times the material thickness. If the hole's diameter or width is less than 2.5mm, the distance should be a minimum of twice the material's thickness plus the bend radius. For larger holes, the spacing should be the bend radius plus 2.5 times the material thickness.
Slot to Form: When bending near long slots, maintain a spacing of the bend radius plus a minimum of four times the material thickness to prevent deformation.
Notches & Tabs: Ensure notches and tabs are at least 1.5 times the material thickness to prevent breakage during stamping.
Corners: For easy manufacturing, the radius of the punch and die for forming corners should be at least four times the material thickness. For materials 1.5mm or thinner, avoid sharp corners.
Squareness: Stamping to form a square, 90° angle allows for normal variation of plus or minus 1 degree.
Flatness: Avoid over-specifying flatness, as it may require costly secondary operations. Specify flatness requirements reasonably.
L-Shaped Parts: Include a bend relief notch in L-shaped parts to avoid fractures and cracks.
Grain Direction: Consider grain direction, especially for hard stocks. Avoid having the bend line of sharp V-bends parallel to the grain direction to prevent cracking. A larger bend radius may also be needed for harder materials.
Burrs: Burrs can occur during stamping and can reach heights of up to 10% of the material thickness. Minimize burr severity by avoiding complex cutouts and sharp corners where possible. Note burr direction in the design to account for them during the metal stamping process.
Shapes: Simple shapes like rounds and squares with sufficient corner radii are easier to draw in stamping. Complex shapes or irregular shapes may increase the difficulty and production cost.
Feature Distortion: Be mindful of distortion when holes and slots are too close to forms, edges, or each other, especially in drawn parts. Account for potential deformation in the design process.
By following these guidelines, you can improve the efficiency and quality of the metal stamping process and reduce the likelihood of defects and issues during manufacturing.

The Tolerance of Metal Stampings
The tolerance range for metal stampings typically varies based on specific design requirements and application needs. Tolerance refers to the permissible deviation in dimensions during the manufacturing process to ensure the quality and functional requirements of the parts.
In metal stampings, controlling tolerances is crucial to maintaining product quality and performance. Here are some common examples of tolerance ranges:
Dimensional Tolerance: Dimensional tolerance refers to the allowable deviation in dimensions such as length, width, thickness, etc., of the parts. For example, for a part with a length of 100mm, the dimensional tolerance can be ±0.1mm, indicating an allowable deviation range of 99.9mm to 100.1mm.
Flatness Tolerance: Flatness tolerance measures the levelness of the part's surface. It describes the maximum distance between the part surface and an ideal plane. For example, the flatness tolerance can be 0.1mm, indicating a maximum distance of 0.1mm between the part surface and the ideal plane.
Parallelism Tolerance: Parallelism tolerance describes the deviation between parallel surfaces of the part. It measures the maximum difference in distance between the parallel surfaces. For example, the parallelism tolerance can be 0.05mm, indicating a maximum distance difference between the parallel surfaces of 0.05mm.
Roundness Tolerance: Roundness tolerance measures the roundness deviation of circular parts. It describes the maximum distance between the curve around the circular part and an ideal circle. For example, the roundness tolerance can be 0.03mm, indicating a maximum distance between the curve around the circular part and the ideal circle of 0.03mm.
These tolerance ranges are just examples, and actual tolerances should be determined based on specific design requirements and application needs. During the design process, factors such as part functionality, assembly requirements, and manufacturing feasibility need to be considered to determine the appropriate tolerance ranges.
Applications of Metal Stamping Dies:
Metal stamping is a forming process that shapes and molds sheet metal workpieces between a punch press and a die. Metal stamping dies are tools attached to the stamping press. They manipulate the workpiece and provide support for its formation. Unlike other bending processes, stamping relieves internal stresses in the metal, preventing post-stamping springback or deformation.
Metal stamping finds extensive use in various applications and is a versatile process capable of high-volume production. Custom metal stamping dies can be configured for a wide range of applications, including:
