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.

For those struggling with the molding and processing of rubber products!
