This is a case study of a heat sink designed using sheet metal. While many heat sinks are made from machined blocks, this was a prototype request utilizing sheet metal processing to achieve weight reduction. The product features 14 mountain bends, and for the mountain sections, we created two sets of simple molds (forming mold + finishing mold) in-house and pressed them. Even the slight warping that occurs at the end was adjusted one by one by hand while measuring with inspection equipment, allowing us to meet the challenging overall length tolerance of ±0.3, which is difficult to achieve with continuous bending. The simple molds were developed based on a database of accumulated plastic processing data, calculating the unfolding length and material elongation rate, with all processes from design to production handled in-house. This also shortened the time required for mold production, ultimately reducing costs and shortening delivery times. 【Overview】 ■Material: A1050 ■Size: 47×126×21mm ■Thickness: t1.0 ■Accuracy: ±0.2 ■Quantity: 10 ■Delivery time: 10 days *For more details, please refer to the related links or feel free to contact us.

Here is an example of a sheet metal part made from SUS304CP. We have bent small parts measuring less than 20mm into a U-shape. Despite the thickness of 1.0mm and the dimensions related to the bending area, there was a tolerance requirement of “±0.05”. By conducting test machining, we meet the dimensional tolerance of “±0.05”. Furthermore, for the U-shaped long holes with a tolerance of “±0.015”, we use laser processing. By performing blank processing with a high-precision fiber laser cutting machine dedicated to thin sheets, we finish precision holes without the need for processes like reaming or milling. This allows us to eliminate manual finishing processes even for products with tolerance requirements of less than “±0.1”, leading to cost reductions. 【Overview】 ■Material: SUS304CP ■Size: 7.6×6.0×20.0mm ■Thickness: t1.0 ■Precision: ±0.1 ■Quantity: 60 ■Delivery time: 4 days *For more details, please refer to the related links or feel free to contact us.

Here is an example of a product with double R bends. When forming R bends using a mold, it is difficult to predict the effects of springback, and it is believed that considerable time is required for mold design and fabrication. In particular, the material used this time is spring steel (SUS304CSP-1/2H), and due to the strict conditions and the complexity of the double R bends, the mold structure is also complicated. Therefore, instead of creating a dedicated mold, we produced the product using standard bending dies with a feeding bend. By finely adjusting the bending depths on both sides, we were able to achieve a dimensional accuracy of “±0.2” for the R bends, ensuring dimensional precision while completing 10 pieces in one week. 【Overview】 ■Material: SUS304CSP-1/2H ■Size: 27×85×50mm ■Thickness: t0.5 ■Accuracy: ±0.2 ■Quantity: 10 ■Delivery time: 7 days *For more details, please refer to the related links or feel free to contact us.

We received Super Dyma (high corrosion-resistant coated steel plate) from our customer and would like to introduce a case of the brackets we manufactured. The key points of this product are the "tall M6 bushings" and the "90° bend close to the bushing." There are four M6 bushings, and we were instructed to have at least three effective threads. To meet this requirement, it was necessary to achieve a height of more than 2.5 times the plate thickness. Based on past performance, we created a simple mold according to the designed values, but we were unable to satisfy the height requirement. Therefore, we remade the mold, reducing the size of the female mold and thinning the plate to secure the height. 【Overview】 ■ Material: Super Dyma ■ Size: 118×115mm ■ Plate thickness: t1.2 ■ Accuracy: ±0.05 ■ Quantity: 35 ■ Delivery time: 10 days *For more details, please refer to the related links or feel free to contact us.

Here is an introduction to a processing case of small-diameter bar ring taps for thin plates. In sheet metal processing, bar ring taps are often used starting from M3, but this product had processing instructions for an M2 bar ring tap. This time, since the plate thickness was only 0.3mm, after performing the bar ring processing, we used a cutting tap, which resulted in the material being thinned out and the tip breaking. Therefore, at thinplate-sheetmetalprocessing.com, we developed a dedicated mold in-house and processed it using a rolling tap, achieving a clean finish without any breakage. 【Overview】 ■Material: C5191-1/2H ■Size: 12×24×5mm ■Plate thickness: t0.3 ■Accuracy: ±0.1 ■Quantity: 10 ■Delivery time: 5 days *For more details, please refer to the related links or feel free to contact us.

This time, we would like to introduce a case of processing stainless steel hairline material. Hairline material is often used for exterior parts, and this time there was a request for no scratches. Our company has implemented a unique approach with the female mold, processing while keeping the masking seal in place to avoid leaving marks from the mold. Additionally, by using a bending machine equipped with an angle sensor, we achieve stable processing. 【Case Overview】 ■Material: SUS304HL ■Size: 60×40×80mm ■Thickness: t1.0 ■Precision: ±0.05 ■Quantity: 30 ■Delivery Time: 14 days *For more details, please refer to the PDF document or feel free to contact us.

This case involves a thin plate bending product with a thickness of 0.5mm, featuring various tolerances set close to the limits of plastic processing. Due to the large amount of crushing required, processing by pressing would be extensive and costly, so we considered using a different method. Since there are issues with chucking during cutting after bending, we opted for wire processing. The product was processed in an upright position, which required considerable ingenuity in the design of the jig, but we were able to process it without any issues. 【Case Overview】 ■ Material: SUS304 ■ Size: 30×15×6mm ■ Thickness: t0.5 ■ Precision: ±0.03 ■ Quantity: 45 ■ Delivery Time: 10 days *For more details, please refer to the PDF document or feel free to contact us.

This time, we would like to introduce a case study of a product processed by combining bending and machining. Our company has chosen a method that removes excess areas by milling after bending, finishing to the shape as per the drawings. By combining machining, we can handle even low-height bends without any issues. Additionally, this bend has an inner radius of R1.6 and a width of only 5mm, which cannot be accommodated with standard types. However, we design and manufacture dedicated molds in-house for processing. 【Case Overview】 ■Material: C2801-1/4H ■Size: 13×25mm ■Thickness: t1.6 ■Precision: ±0.2 ■Quantity: 70 ■Delivery Time: 7 days *For more details, please refer to the PDF document or feel free to contact us.

This time, we will introduce a case of bending processing of polished special strip steel (S50CM). Polished special strip steel is characterized by its high carbon content, which makes it harder when heat is applied, and as a result, it can develop cracks or breaks when bent. To suppress the hardening of the material, our company chose wire processing for the blank cut. By performing a second cut, we were able to satisfy the dimensions for the elongated holes with tolerances. 【Case Overview】 ■Material: S50CM ■Size: 26×110×9.0mm ■Thickness: t1.6 ■Accuracy: ±0.1 ■Quantity: 100 ■Delivery Time: 8 days *For more details, please refer to the PDF document or feel free to contact us.

This time, we would like to introduce a case where connector pins were manufactured from blanks provided by the customer. The blanks were supplied with only elongated holes drilled. The pins were arranged in a single sheet for a total of 54 pieces, and the request was to process them into individual shapes. When cutting the pin outlines with a laser to match the elongated holes, it is important to align the centers of the elongated holes and the pin sections. By adding a process to reduce distortion, our company was able to align the positions simply by fine-tuning the laser program. 【Case Overview】 ■ Material: C1020-1/2H ■ Size: 1.5×4.5×12mm ■ Thickness: t0.64 ■ Accuracy: ±0.03 ■ Quantity: 500 ■ Delivery Time: 10 days *For more details, please refer to the PDF document or feel free to contact us.

This time, we will introduce a case of processing a material that has undergone special surface treatment on pure aluminum (A1100). One side of the pure aluminum, which is a highly reflective material, has been treated with PVD (Physical Vapor Deposition), raising concerns about adverse effects from back reflection during laser processing of blank cuts. In the bending process, we prevented scratches by processing while keeping the protective tape on. Although it was a challenging task due to the conditions of bending a thin aluminum sheet (t0.5) with protective tape, which makes it difficult to achieve the desired bending angle, we were able to handle it without any issues. [Case Overview] ■Material: A1100 ■Size: 300x40mm ■Thickness: t0.5 ■Accuracy: ±0.1 ■Quantity: 40 ■Delivery Time: 7 days *For more details, please refer to the PDF document or feel free to contact us.
