Rubber products are used in many situations, such as "wanting to use it as a packing for machines" and "wanting to use it as a cushioning accessory" in machinery and transportation equipment. Among these, troubles such as "rubber deteriorates quickly" and "rubber burrs negatively affect appearance" frequently occur. The root cause of these troubles often lies in the design process, and if not addressed, it can lead to frequent machine failures and quality complaints. 【Examples of problem-solving at our company】 1. Rapid material degradation ⇒ Extended lifespan of over one month with appropriate materials! 2. Concerns about leftover burrs ⇒ Significant reduction in man-hours with a specification change that makes burrs invisible! 3. Wanting to create alternative parts without drawings ⇒ 40% reduction in procurement costs through shape design and material selection! We are currently offering a collection of case studies that address such design-related issues. Once a product is launched, making corrections is difficult, so it's best to address these issues beforehand! Shin-Ei Rubber Industry will support you from the design stage.

■Specific Concerns "I want to prototype a rubber product with a complex shape." "I was turned down by other companies because it was too complex. Is there any way to prototype it?" ■Cause The shape is too complex for a mold to be feasible. ■Solution We examined the mold structure and identified the risk of mold damage due to the product shape. We proposed a product shape that avoids the risk of mold damage. ■Effect We modified the shape without affecting functionality and successfully prototyped it. We avoided the risk of mold damage during mass production. We also confirmed mass producibility during prototyping, reducing labor costs. ■Customer Feedback "I fully understood the reasons I was turned down by other companies. I'm glad we could prototype without changing functionality, even with a modified shape." "If we had moved directly to mass production, it would have been a disaster. I appreciated the simultaneous confirmation of mass producibility." *For more details, please download the materials or feel free to contact us.*
