[VE Case] Total length 510mm, inner diameter slope 0.1° molding die

Integrated molding of an unusual tubular shape (kamaboko shape)! We launched production from the start of construction in just 60 days.

The customer manufactures and sells OA equipment and was considering a non-cylindrical, oval shape for product development to increase filling capacity. However, it was anticipated that the oval shape would have greater release resistance compared to the cylindrical shape. In this product, by creating a mold with a unified cylindrical shape that does not require division, we aimed to significantly reduce the costs associated with mold production and product costs. With an overall length of approximately 510mm and a draft angle of 0.1°, it would be difficult to extract such a long product using a sliding structure in traditional molds. Therefore, we reduced the draft angle and developed a sliding core operation method and cooling structure to alleviate the sliding core's impact on the product, which became a key point in mold production. [Challenges and Considerations in Product Development] - Consideration of an oval shape instead of a cylindrical shape to increase filling capacity - Anticipation that the oval shape would have greater release resistance compared to the cylindrical shape - Due to the expectation that high release resistance would prevent the product from being extracted from the mold, a proposal was considered to divide the different cylindrical shapes and join them through welding - Exploration for ideas to realize products other than the two-part proposal for the different cylindrical shape *For more details, please refer to the PDF document or feel free to contact us.*
