[Processing Example] Small diameter dowel pin machining, handled with in-house manufactured molds.

[Processing Example] Small diameter dowel pin machining, handled with in-house manufactured molds.

A dedicated mold was created using wire cutting! This is a case where interference of the mold was avoided by bending two places simultaneously.

We would like to introduce a case study of precision sheet metal processing made from 0.5mm thick stainless steel spring material (SUS304CSP-1/2H). This product features a small diameter dowel hole processing (half-pierce) with a diameter of Φ1.1mm. Generally, dowels are often Φ3 or larger, and a Φ1.1mm dowel requires a custom mold, which incurs mold production costs and longer lead times. Therefore, at thin sheet metal processing.com, we have achieved cost reduction and shortened lead times by manufacturing dedicated molds in-house using our machining center. 【Overview】 ■Material: SUS304CSP-1/2H ■Size: 20×65mm ■Thickness: t0.5 ■Accuracy: ±0.1 ■Quantity: 45 ■Lead Time: 10 days *For more details, please refer to the related links or feel free to contact us.

[Processing Example] Non-die bending of special-shaped R bends and feed bends.

[Processing Example] Non-die bending of special-shaped R bends and feed bends.

10 pieces in one week! We produced the products using standard bending dies without creating dedicated molds.

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.

[Processing Example] Achieving Short Delivery Times with Precision Sheet Metal Processing Incorporating Cutting Machining

[Processing Example] Achieving Short Delivery Times with Precision Sheet Metal Processing Incorporating Cutting Machining

Even shapes that cannot be bent with standard bending types can be accommodated! By machining the tip, we can meet delivery deadlines.

We would like to introduce a case study of a busbar manufactured at thinplate-metalworking.com. This product has two key points. The first point is the processing of a step with a height of 0.5mm in four stages at the tip. By selecting a machining center from our extensive equipment inventory and performing cutting on the tip, we were able to meet the delivery deadline. The second point is that we created a Z-bend section, which cannot be bent with a bender, using a simple mold. Utilizing the technical skills and abundant equipment we have developed over time, we flexibly respond to processing that goes beyond just plastic processing. 【Overview】 ■ Material: C1020-1/2H ■ Size: 67×56×13mm ■ Plate thickness: t2.0 ■ Precision: ±0.1 ■ Quantity: 2 ■ Delivery time: 7 days *For more details, please refer to the related links or feel free to contact us.

[Processing Example] Consistent support from reaming H8 tolerance holes to electropolishing.

[Processing Example] Consistent support from reaming H8 tolerance holes to electropolishing.

Supports various types of processing! After finishing the machining, electrolytic polishing is performed at partner factories.

Here is an example of a thin plate grip made from SUS304CSP-1/2H. The first point is that there are slits at the bending locations. When the distance between the bending position and the hole is close, deformation can occur during bending, but by providing a relief, deformation can be prevented. Additionally, the second point is that for the four H8 tolerance holes, high-precision machining for fitting tolerances is difficult with laser processing, so our company ensures accuracy by finishing these holes with reaming. 【Overview】 ■Material: SUS304-1/2H ■Size: 30×60×12mm ■Plate thickness: t1.2 ■Accuracy: ±0.025 ■Quantity: 40 ■Delivery time: 10 days *For more details, please refer to the related links or feel free to contact us.

Actively introducing advanced equipment! Achieving a smooth R shape and a tolerance of "±0.2"!

Here is an example of a precision sheet metal part made from spring material SUS304CSP-3/4H. The feature of this product is that the shapes on the left and right are symmetrical when viewed from the center, but the bending shapes at the front and back are different. To create different R shapes from the blank, a bending-like drawing process is used. Our company utilizes blank simulation software to calculate the unfolding length, significantly reducing the number of tests. In addition to our know-how, we also achieve reductions in man-hours and shortened delivery times by using simulation software. 【Overview】 ■ Material: SUS304-CSP-3/4H ■ Size: 45×45×14mm ■ Plate thickness: t1.2 ■ Accuracy: ±0.2 ■ Quantity: 160 ■ Delivery time: 10 days *For more details, please refer to the related links or feel free to contact us.

[Processing Example] Difficult bending processing of pure copper, achieving coaxiality of φ0.1 while suppressing twisting.

[Processing Example] Difficult bending processing of pure copper, achieving coaxiality of φ0.1 while suppressing twisting.

We are also skilled in processing copper thin plates with a thickness of 1.0mm or less! Blanks are processed with a fiber laser!

We would like to introduce a case of pure copper coils manufactured by Hakubanshinkakou.com. This product has a very narrow U-bend spacing of 2mm, which cannot be bent using standard molds from manufacturers. Due to its shape, it is prone to twisting, and the springback causes the tips to open, making it difficult to ensure precision. At our company, we have developed dedicated molds in-house and made improvements to the processing method, allowing us to meet a parallelism tolerance of "0.1" after the U-bend. Please feel free to consult us for high-precision sheet metal processing as well. 【Overview】 ■ Material: C1100P-1/2H ■ Size: 50×50×6mm ■ Thickness: t2.0 ■ Precision: ±0.1 ■ Quantity: 120 ■ Delivery time: 10 days *For more details, please refer to the related links or feel free to contact us.

[Processing Example] Brass electronic components, distortion-free with fiber laser processing.

[Processing Example] Brass electronic components, distortion-free with fiber laser processing.

We have numerous processing achievements for connector parts made of pure copper and others! We handled the production of 100 units in 10 days.

We would like to introduce a processing example of precision sheet metal parts made of brass. This product is a connector made from C2680-1/2H. Brass is considered a high-reflective material, similar to copper, and cannot be processed with CO2 lasers due to reflection. However, our company owns a fiber laser processing machine, allowing us to perform blank cutting with laser processing. Even for shapes like elongated terminals that are prone to deformation due to thermal effects, processing with a fiber laser minimizes deformation caused by heat. 【Overview】 ■Material: C2680-1/2H ■Size: 18×40×35mm ■Thickness: t0.8 ■Accuracy: ±0.15 ■Quantity: 100 ■Delivery time: 10 days *For more details, please refer to the related links or feel free to contact us.

[Processing Example] Reducing initial costs with mold-less processing through VE proposals.

[Processing Example] Reducing initial costs with mold-less processing through VE proposals.

We offer a finish with a file! We have various in-house made types of half earrings in different diameters.

Here is an example of precision sheet metal parts manufactured from SPCC. This product is characterized by its half-piercing feature. During bending, bulging occurs on the outer shape, but since there are no tolerance indications for the product's outer shape, we addressed this with a filing finish. Additionally, by using a filing finish, we eliminated the need to create a mold, which also contributed to cost reduction. 【Overview】 ■Material: SPCC ■Size: 15×30×25mm ■Thickness: t1.6 ■Precision: ±0.1 ■Quantity: 15 ■Delivery time: 7 days (including surface treatment) *For more details, please refer to the related links or feel free to contact us.

Bending with a precision of ±0.03 over 20 times! Finished beautifully with our unique technology.

Bending with a precision of ±0.03 over 20 times! Finished beautifully with our unique technology.

Multiple dedicated molds for bending and drawing have been produced! Not only can we achieve high-precision processing, but we can also respond with short delivery times!

We would like to introduce a case study of a cover for electronic components made from SUS304CSP-H with a thickness of 0.4mm. This product required not only deep drawing but also 20 bending processes, with a precision requirement of "±0.03". Due to the high yield strength of spring materials, they exhibit greater springback compared to general metals, making it necessary to have very high technical skills to ensure a high precision of "±0.03" after multiple bends. In this case, we used the hardest H material, and due to the possibility of cracking depending on the rolling direction, we implemented various measures not only during bending but also during blanking. 【Overview】 ■ Material: SUS304CSP-H ■ Size: 26×26×6.5mm ■ Thickness: t0.4 ■ Precision: ±0.03 ■ Quantity: 100 ■ Delivery time: 10 days *For more details, please refer to the related links or feel free to contact us.
