"I don't really understand rubber..." Are you choosing the type of rubber "somehow"? "I just replaced it the other day, and it's already deteriorated." "It's a hassle to replace it, so I want something to be done about it." To solve such concerns, you need to consider the purpose of using rubber (the effect you want to achieve the most) and the usage environment. There are many types of rubber. For example, "rubber that is resistant to deformation," "rubber with grip," "rubber that is weak to heat," "rubber that dissolves in oil," and so on. On the other hand, the environments in which rubber is used are diverse. You need to clarify the effect you want to achieve the most, choose a rubber that can deliver that effect, and then select a rubber that can withstand the usage environment. Currently, our company is offering a clearly visualized document categorized by the functions desired in rubber, the "Rubber Type List by Desired Functions," for free. We will support you in choosing the right rubber for your application! ★ You can download the "Rubber Type List by Desired Functions" from the link below. Use the right rubber for your needs to assist in your everyday manufacturing.

"Rubber has good grip and elasticity, which is great, but compared to a similar material like 'resin,' it's a bit more expensive..." That's because there is a significant difference in the "method of production." Making rubber, in a nutshell, is similar to "making bread"! Resin is a "thermoplastic" that hardens when cooled, allowing for quick molding, but rubber is a "thermosetting" material that, like bread, requires baking, which takes more effort. Just like with bread, there are many similarities, such as kneading and aging... Additionally, one of the characteristics of rubber is that you can design the formulation according to the desired properties and freely manipulate the final outcome of the rubber. Currently, our company is offering a free resource that explains rubber production by comparing it to bread making, titled "The Great Encyclopedia of Rubber Making." We support your manufacturing endeavors! ★ You can download "The Great Encyclopedia of Rubber Making" from the link below. Understand how to make rubber and apply it to your everyday manufacturing!

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 rubber products that comply with the Food Sanitation Act, but I'm not sure about it."
