In pressed products, the expression "no burrs" is often used in drawings. Burrs, also referred to as "flashes," are formed as sharp protrusions along the extension of the fracture surface of sheared products. The quality of pressed products is often judged based on the presence of burrs and flashes, with their height frequently determining the quality assessment. Since they reflect the wear condition of the cutting tools (punches) well, they also serve as an indicator for determining the timing of mold maintenance. *For more detailed information, please refer to the related links.

A mold is typically a tool used for mass-producing products through processes such as resin molding, press processing, forging, and casting. Among them, a "simple mold" refers to a basic press mold that is suitable for cases where small-lot production is needed before creating a mass production mold, or when one wants to prototype to verify shape and functionality. For products with high difficulty, mold design aimed at mass production is required, along with the need to minimize troubles during mass production to create highly productive molds. *For detailed content of the column, you can view it through the related links.

Shaving processing is a term used in press processing, where the cut edge created by a punching press is further processed by pressing again to remove the surface and achieve a smooth and highly precise cross-section. It is common to shave (press) from the flared side of the press cross-section towards the burr side. When the plate thickness increases, a single shaving may not be sufficient, so multiple shavings may be necessary. *For more detailed information, please refer to the related links.

First, in press processing and sheet metal work, "dabo" refers to a non-through protrusion shape created by applying pressure to a part of the material using a mold. Dabo forming refers to the process of shaping a convex shape (protrusion) on a metal sheet, primarily used for positioning in the welding or assembly of metal parts, and this convex shape is called "dabo." In addition to being used for positioning parts, dabo can also serve functions such as a stopper. *For more detailed information, please refer to the related links.

"Precision shearing" and "cold forging" are separate techniques in press processing, but by applying both techniques within a single mold, it becomes possible to achieve shapes and precision that are difficult to realize with conventional press processing. At our company, we can process products that involve crushing materials into the required shape while finishing the sides of the product with precision shearing. There are limitations on the shapes we can accommodate, but we believe this is an effective option when considering the rationalization of machined products. *For more details, you can view the related links.

Fine blanking (FB processing) is a press processing technology that performs blanking (punching) with precision. This principle is based on the "hydrostatic effect," which states that applying pressure to metal increases the force of plastic deformation. In general press processing, the workpiece is placed on the die, and pressure is applied with a punch to perform the blanking; during this process, an appropriate gap (clearance) between the die and the punch is necessary. *For more detailed information, please refer to the related links.

If there are no instructions on the drawing, the finish of the "shear surface" for standard pressed parts is not considered important. So, in what cases is a "clean shear surface" necessary? While we may not know the specific applications of the parts, we will consider this based on information from our customers. For the products we manufacture, there are often instructions regarding the "shear surface" on the drawings, such as "ensure over 70% shear surface" or, conversely, expressions like "the combined area of the fracture surface and the droop surface should be 30% or less." *For detailed content of the column, please refer to the related links.

It is not often that the "surface roughness" of the shear surface is required, but when looking at the shear surfaces of typical pressed products, it can be confirmed that "vertical lines" are present. Among the products we manufacture through pressing, there are parts with gear shapes and cam shapes. When producing such functional parts through pressing, the finish of the shear surface becomes important. Since it serves as the contact surface and sliding surface with counterpart parts, achieving a shear surface without irregularities can lead to smoother engagement and sliding with the counterpart parts, resulting in products that excel in wear resistance and contribute to quiet operation. *For more detailed information, please refer to the related links.

In press processing, shearing is a method used for cutting metal sheets. There are various types of shearing processes, such as drilling, punching, and notching, but it can be said that press processing is composed of combinations of "shearing processes." Shearing is a method of cutting by applying pressure to a metal sheet using a pair of upper and lower molds. It may be easier to understand if you imagine replacing the principle of "cutting paper with scissors" or "making holes with a punch" with a metal sheet. *For more detailed information, you can view the related links.

Machining by cutting allows for high precision finishing, but requires a certain amount of processing time. Compared to cutting, press processing is inferior in terms of precision, but it excels in production efficiency. If parts that were previously manufactured by cutting can be produced using press processing, significant cost reductions can be expected. *For more details on the column, please refer to the related links.

In recent years, the demand for high-tensile materials has been increasing due to the need for lightweight components in automobiles and other applications. Compared to standard materials, high-tensile materials can achieve weight reduction while maintaining strength; however, their strength also leads to higher forming loads, making processing more difficult. This column provides detailed information about what high-tensile materials are, along with their advantages and disadvantages. *For more details, you can view the related links.

In press processing, there is a basic technique called "shearing," which refers to cutting a sheet of material using a pair of upper and lower molds. This processing is aimed at the action of "cutting" the material, and there are various types of shearing processes, ranging from simple cutting to drilling, punching, and notching. The mechanism involves placing the metal material on the die (the lower mold) and applying pressure from above with a punch (the upper mold), thereby cutting it by applying a force that cannot maintain its original state. *For more detailed information, please refer to the related links.
