The time required for mold production has also been shortened! We were able to reduce costs and shorten delivery times!
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.

basic information
**Features** - There are 14 bends, and the mountain parts are pressed using two sets of simple molds made in-house. - Since even a slight error in pitch accumulates and eventually leads to significant misalignment, managing the dimensions between pitches is crucial. - Any slight warping that occurs at the end is measured with inspection equipment and adjusted manually one by one. - It is possible to satisfy a challenging overall length tolerance of ±0.3 in continuous bending. - The simple molds are developed based on a database of accumulated plastic processing data, calculating factors such as unfolding length and material elongation rate, with all design and production handled in-house. *For more details, please refer to the related links or feel free to contact us.*

Company information
At Nishino Seiki Seisakusho Co., Ltd., we have a wide range of equipment and systems that can handle both sheet metal and press processing, as well as machining such as lathes and machining centers, allowing us to comprehensively meet all customer requests for prototypes and parts processing. We also manufacture dedicated molds and tools necessary for processing prototypes and products requested by customers, such as bending molds, punching molds, and drawing molds, in-house. This eliminates the need to outsource mold production, enabling us to achieve shorter lead times for processing. Additionally, we can quickly make creative adjustments, fine-tuning, and improvements to molds in-house, which significantly enhances the quality and precision of the finished products. We cover both sheet metal and press processing as well as machining within a single company, leveraging our uniquely developed processing technologies and know-how to challenge ourselves daily with the processing of fine, miniature parts and difficult materials.
