■Concerns "I want the burrs to be less noticeable since it will be used in prominent areas." "When trying to remove the burrs, they become too noticeable, so I would like the product design to be such that the burrs are not visible." ■Cause With the usual product structure, burrs protrude from the side, making it impossible to completely remove them. ■Solution Improved the structure so that the burrs come out directly underneath and are not visible from the surface. ■Effect The burrs are no longer visible. Defects due to remaining burrs have been eliminated, and yield has significantly improved. ■Customer Feedback "After reviewing the product structure multiple times, we now have a product where the burrs are not visible." "The defect rate has dramatically improved, and productivity has greatly increased, which has been very helpful." *For more details, please refer to the PDF document or feel free to contact us.*

■Specific Concerns "I want to prototype rubber products with complex shapes that are larger than hand size." "This is my first attempt, so I want to try various rubber materials." ■Common Issues Development costs ■Solutions Create molds that can also be used for mass production and conduct prototyping. Prepare multiple rubber materials during prototyping. ■Effects Functionality confirmation through prototypes. Reduction of labor and costs during mass production startup. ■Customer Feedback "I had given up on prototyping because the product size is large and the shape is complex, but I'm really glad I was able to prototype." "Although there were mold costs, the fact that the molds can be repurposed for mass production allowed us to reduce labor and costs during the mass production startup!" *For more details, please download the materials or feel free to contact us.*

■Specific Concerns "I was using natural material parts in machines that process metal, but I can no longer procure those parts due to business closure." "I don't know much about rubber, but I wonder if a substitute can be made from rubber. I would like someone to take a look." ■Causes The application and usage environment are not well understood. ■Solutions Thorough on-site investigation of application and usage environment for rubber material selection. Comprehensive support from product design, mold creation, to molding based on actual materials of different types. ■Effects Functionality improved compared to the old material. Cost reduced by 70% compared to the procurement price of the old material. ■Customer Feedback "I really appreciated the one-stop support from material selection to product design and molding!" "I was prepared for a cost increase while searching for substitutes, but I was surprised to see such a significant cost reduction!" "I was turned away by other rubber suppliers, but I was grateful for the willingness to consult with me!" *For more details, please download the materials or feel free to contact us.*

■Specific Concerns "The machines we use in-house have severe oil leaks, which is reducing our production efficiency." "I think using rubber products could prevent oil leaks, but I don't know how to proceed." ■Causes Not understanding rubber prevents us from realizing what we want to achieve. ■Solutions Product design based on on-site surveys and hearings. Comprehensive support from mold design to material selection, prototyping, and mass production. ■Effects We were able to realize our ideas that had been in development for about two years and eliminate oil leaks. By providing comprehensive support, we were able to launch mass production in about two months. ■Customer Feedback "Thanks to the product design work, we were able to concretize the discussion all at once." "Regarding material selection, the explanations of the characteristics and pros/cons of each rubber material allowed us to proceed with confidence." "We were able to achieve our primary goal of preventing oil leaks, which improved production efficiency." *For more details, please download 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."

"We are developing a new product, and we absolutely need rubber parts." "Can you prototype rubber parts?" Of course! But what about the cost? What about the delivery time? What about the quality? There are various questions. There are two main methods for prototyping rubber products: 1. Molding prototypes using molds 2. Prototyping through machining Each prototyping method has different characteristics, cost considerations, and timelines depending on the purpose and development phase. Currently, our company is offering a free resource that visualizes the appropriate prototyping methods for rubber products titled "Complete Guide to Prototyping Rubber Products." We can suggest prototyping methods that suit your needs. In this helpful resource, we introduce a decision flow for prototyping methods tailored to specific purposes and situations, and we provide a comprehensive explanation of each prototyping method. ★ You can download "Complete Guide to Prototyping Rubber Products" from the link below. We hope it will be useful for your everyday manufacturing.

■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.*
