[Processing Example] Completed a 400mm bead drawing in 3 days using a laminated mold.

We will introduce a case where we prioritized delivery time by selecting a layered mold and were able to complete it in 3 days!

This time, we are introducing a case of a long, narrow shape measuring 430x20mm, with a bead drawing applied over a length of 400mm. The bead drawing had a width of 2.7mm and a length of 400mm, but since the dimensional tolerances other than the drawing height and the requirements for the convex part's R shape were lenient, a dedicated stacked mold was manufactured and processed. Although there were concerns about warping due to the additional bead drawing on the elongated shape, we were able to meet the warping limit condition of 0.5 max by incorporating a process to remove strain. [Case Overview] ■ Material: NSECC-QS1 ■ Size: 430x20×15mm ■ Plate Thickness: t1.2 ■ Precision: ±0.2 ■ Quantity: 3 ■ Delivery Time: 3 days *For more details, please refer to the PDF document or feel free to contact us.

[Processing Example] Achieving high precision and short delivery times through the combination of V-bending technology.

[Processing Example] Achieving high precision and short delivery times through the combination of V-bending technology.

A case that meets the constraints of no inner radius bending, no bulging on the outer side of the bend, and no deformation of holes.

This time, we are introducing a case where multiple V-bending techniques were combined to meet strict tolerance requirements. Due to the constraint of "no inner R on the bend," after V-bending with a sharp-edged mold, bottoming was performed with a dedicated mold. By adding this process, we minimized the inner R of the bend to the extreme and reduced variation in bending. Not only through bending processing but also by innovating in the preceding and following processes, we achieved a short delivery time of 3 days. 【Case Overview】 ■ Material: SUS304 ■ Size: 50x30x30mm ■ Plate Thickness: t2.0 ■ Precision: ±0.1 ■ Quantity: 60 ■ Delivery Time: 3 days *For more details, please refer to the PDF document or feel free to contact us.

[Processing Example] Hemming bending processing of a 0.3mm thick phosphor bronze spring material.

[Processing Example] Hemming bending processing of a 0.3mm thick phosphor bronze spring material.

We have a dedicated mold for Hemming bending that we developed in-house! We can accommodate thicknesses of 1.0mm or less.

We would like to introduce a case study of processing leaf springs that include hemming bends. Due to the thickness of 0.3mm, there are often opportunities to purchase the material in coil form when arranging materials. Since it is wound in a roll, the material itself has warping and distortion, making it impossible to process the blanks as is. At our company, we stabilize the accuracy of blank processing by removing warping with specialized machinery, and we further minimize warping by using a fiber laser processing machine. 【Case Overview】 ■ Material: C5191-1/2H ■ Size: 40×46×10mm ■ Thickness: t0.3 ■ Accuracy: ±0.1 ■ Quantity: 10 ■ Delivery Time: 5 days *For more details, please refer to the PDF document or feel free to contact us.

[Processing Example] T1.0 aluminum with M2 small diameter bar ring tapping.

[Processing Example] T1.0 aluminum with M2 small diameter bar ring tapping.

An example of processing M2 bar rings on a 1.0mm thick A5052 plate after bending!

This time, we will introduce a case of precision sheet metal processing that includes a small-diameter bar ring tap. There was a specification for an M2 bar ring on a 1.0mm thick A5052 plate. Due to its small diameter and slender shape, it is prone to breaking, so extreme caution is required during processing. In this case, the bar ring tap was located adjacent to a bend and was in a position where it could interfere with the shape. Since there was a risk of it being crushed if processed before bending, the bar ring tap processing was carried out after bending. [Case Overview] ■ Material: A5052 ■ Size: 10×30×60mm ■ Plate Thickness: t1.0 ■ Accuracy: ±0.1 ■ Quantity: 60 ■ Delivery Time: 10 days *For more details, please refer to the PDF document or feel free to contact us.

[Processing Example] Achieving Short Delivery Times with Proposal for Feed Bending (FR Bending)

[Processing Example] Achieving Short Delivery Times with Proposal for Feed Bending (FR Bending)

We will introduce a case where selecting the sending bend (FR bend) enabled a quick response with a short delivery time.

This time, we would like to introduce a processing case of a product made of SUS304-H material, which has large R bends (R14.5) in two places. Due to a short delivery request, we only had one week for the production period. Since we did not have a mold for R14.5 and could not secure time for its production, we proposed processing using a sending bend. By adding a process to reduce warping before bending, we were able to mitigate warping after bending and achieve satisfactory precision. 【Case Overview】 ■ Material: SUS304CSP-H ■ Size: 300x160x26mm ■ Plate Thickness: t0.8 ■ Precision: ±0.2 ■ Quantity: 10 ■ Delivery Time: 7 days *For more details, please refer to the PDF document or feel free to contact us.

[Processing Example] Achieving high-precision bending processing of ±0.03 through additional processing on supplied materials.

[Processing Example] Achieving high-precision bending processing of ±0.03 through additional processing on supplied materials.

We will respond to inquiries such as "I want to utilize what is currently available" with creativity and technical expertise!

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.

[Processing Example] Machining finish of a short bending section.

[Processing Example] Machining finish of a short bending section.

A processing example that maximally utilizes our strengths, created by combining sheet metal processing and cutting processing.

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.

[Processing Example] High-precision machining with a tolerance of ±0.03, process design to minimize deformation.

[Processing Example] High-precision machining with a tolerance of ±0.03, process design to minimize deformation.

We can handle strict tolerances! We can satisfy precision even in post-processing.

We would like to introduce a processing example of a product made from 0.5mm thick SPTE (tinplate). There is a crushing process on the inside, but due to a tolerance of ±0.03 in width, if the crushing process is carried out as is, the material will spread, and it will not meet the tolerance requirements. At thin sheet metal processing.com, we can accommodate strict tolerances by advancing the processing with a method that takes into account the dimensional changes caused by the crushing process. Please feel free to consult us if you are facing issues with high-precision processing. 【Overview】 ■ Material: SPTE 2.8/2.8 (tinplate) ■ Size: 16×16×14mm ■ Thickness: t0.5 ■ Precision: ±0.03 ■ Quantity: 10 ■ Delivery time: 7 days *For more details, please refer to the related links or feel free to contact us.

[Case Study] Significant Reduction in Work Time through Special Type Design for Process Consolidation

[Case Study] Significant Reduction in Work Time through Special Type Design for Process Consolidation

Successfully achieved a significant reduction in working hours! If you are struggling with short delivery times for precision sheet metal processing, please feel free to consult us.

We would like to introduce a case of precision sheet metal parts that achieved a short delivery time by reducing processes. This product had strict tolerances of "±0.02" at key points such as pitch and hole diameter. Despite the stringent tolerances, there was a request to deliver 300 pieces in 5 days, so we focused on how to reduce the overall working time and built the processes accordingly. In the bending process, we successfully shortened the working time significantly by creating a special mold that allows for cutting while bending. It is unfortunate that we cannot show the mold as it contains proprietary know-how, but the mold we created this time is a culmination of our extensive experience and technical skills. 【Overview】 ■Material: SUS304 ■Size: 6×40×15mm ■Thickness: t0.4 ■Accuracy: ±0.02 ■Quantity: 300 ■Delivery Time: 5 days *For more details, please refer to the related links or feel free to contact us.

[Processing Example] Copper products with a thickness of 0.3, stabilizing quality through various innovations.

[Processing Example] Copper products with a thickness of 0.3, stabilizing quality through various innovations.

We can also handle spring materials that are difficult to process! Please leave the processing of copper products to us.

We would like to introduce a case study of precision sheet metal processing of a copper plate (C1020) with a thickness of 0.3mm. Although it is a simple product that undergoes bending after blank laser processing, there are various concerns. At thin sheet metal processing.com, we are making efforts in each process to dispel those concerns and maintain stable quality. By cutting with a fiber laser processing machine specialized for thin sheets, we minimize distortion and satisfy a tolerance of ±0.05 after bending. Additionally, in the bending process, while copper has a small springback and is easy to bend, the material is soft, and if the pressure is not properly adjusted, the die can bite into the product. Therefore, we process it with appropriate pressure. 【Overview】 ■Material: C1020 ■Size: 6×70×70mm ■Thickness: t0.3 ■Accuracy: ±0.05 ■Quantity: 300 ■Delivery time: 10 days *For more details, please refer to the related links or feel free to contact us.

[Processing Example] Simultaneous processing of three low-height bends

[Processing Example] Simultaneous processing of three low-height bends

Always pursuing methods that can process quickly and cheaply! A case where 60 items were completed in 7 days.

We would like to introduce a case of a long, slender product with a continuous bending of the same shape. The product has an outer dimension of 25x250mm, making it slender and containing many elements that could lead to deformation. We used a fiber laser processing machine with minimal heat impact for the blank cutting, and we considered the cutting order to prevent heat accumulation during processing. This time, we prioritized bending at three locations simultaneously and chose a method that does not require the creation of a simple mold. We conducted test processing using a standard bending die and followed a procedure to reflect the results. This diligent work allows us to shorten the production days compared to creating a large simple mold. 【Overview】 ■Material: EGC-QS1 (SECC) ■Size: 10x25x250mm ■Thickness: t1.6 ■Precision: ±0.2 ■Quantity: 60 ■Delivery time: 7 days *For more details, please refer to the related links or feel free to contact us.
