■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.

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.

"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!

■Specific Concerns "I want to create a large precision gasket for industrial machinery." "There are no rubber manufacturers who can take on the strict precision requirements." ■Cause As the product size increases, it becomes difficult to manufacture high-precision rubber products due to the unique shrinkage of rubber. ■Solution Using large molding machines and trial and error with molding conditions. Innovating the mold to achieve high precision. ■Effect Achieving strict precision. Improving the performance of industrial machinery (maintaining airtightness). ■Customer Feedback "You really helped us achieve the precision we absolutely wanted." "Thanks to you, the performance of the machine improved, and we were able to create a machine that exceeded our expectations." *For more details, please download the materials or feel free to contact us.*

■Specific Concerns "I want to attach a rubber product prototype to a vehicle and test it." "I want to confirm if mass production is feasible with this shape, but I only need one piece." ■Solution Prepare 1 kg of rubber material in small quantities. Create a simple mold and perform prototype molding. ■Effect Produce a test prototype with the minimum necessary rubber material. Identify issues for mass production and incorporate them into the process. ■Customer Feedback "I used to struggle with the minimum material lot when requesting prototypes, but now I feel relieved." "I was able to identify potential issues for mass production early on, which allowed me to effectively apply them to the production process." *For more details, please refer to the materials or feel free to contact us.*

■Specific Concerns "I added an aging inhibitor to prevent deterioration, and now the rubber doesn't burn at all." "I don't understand the reason. We're almost ready to launch." ■Solution By finding compatible chemicals and changing the formulation, we resolved the issue. ■Effects - Reduced molding time to the initially expected duration, improving output. - Improved workability during the mixing of rubber materials, shortening mixing time. - Achieved the desired resistance to deterioration. ■Customer Feedback "Thanks to the improvement in output, we were able to meet the launch deadline." "I realized that compatibility and balance are crucial in the formulation of rubber materials." *For more details, please download the catalog or feel free to contact us.*

■Specific Concerns "I want to add a yellow mark to make part of it stand out." "I want it to be shaped so that the mark cannot be removed." ■Solution Improvement of the rubber material embedding method. ■Effect Eliminated rubber covering and mark misalignment, resulting in a lower defect rate. Improved visibility of the yellow mark enhanced usability for end users. Enabled integrated molding of differently colored materials, contributing to the design quality of rubber products. ■Customer Feedback "This mark has increased visibility for end users, making it easier to draw attention." "This integrated molding can be applied to other rubber products too! I want to challenge the development of high-design rubber products." *For more details, please download the materials or feel free to contact us.*
