Rubber products are used in many situations, such as "wanting to use them as machine gaskets," "wanting to use them as cushioning accessories," and "wanting to use them as substitute parts for discontinued components." However, various unexpected troubles arise that were not anticipated during the initial design, such as "the rubber deteriorates quickly," "the rubber burrs negatively affect the appearance," and "we're getting rubber products made, but we have a mountain of defects." If these troubles are not fundamentally resolved, they can lead to frequent machine breakdowns, quality complaints, and the expansion of hidden losses. The root cause of these troubles often lies in the design process. Many designers express sentiments like, "I don't really understand rubber materials," "the manufacturing side should be able to handle burrs," and "there's nothing we can do without drawings." We have compiled examples of how our company, as a rubber supplier, has resolved these candid concerns from designers into a booklet.

A common complaint about rubber products is "flash remaining." "There is rubber flash left on the product." "Can't we finish the flash more neatly?" When molding rubber, the rubber material is sandwiched in a mold and heated, so any parts that protrude from the mold become rubber flash. A frequent cause of flash remaining is the case where "the press pressure is weak and it hasn't been fully pressed." *For more details, please download the catalog or contact us.*

"We are developing a new product, and we absolutely need rubber parts." "Is it possible to 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 fit 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.

"I want to create a long, thin protector about one meter in length." "There are scratches on the surface, and the yield is very poor." That was the consultation. For long rubber products around one meter, gas marks are likely to appear as the product size increases. Additionally, issues such as color unevenness and weld marks (marks from the joints of the rubber) are also common. As the thickness of the product decreases, the difficulty of molding increases. The main points are: - Material selection - Material preparation method - Temperature - Molding conditions (gas release and pressure, etc.) Particular attention is needed for material selection. Depending on the material, color unevenness or discoloration may occur over time, negatively affecting appearance. Since keeping the surface clean is important for "areas that are frequently seen by the end customer," it is necessary to consider color changes over time when selecting materials. By leveraging our past achievements in long rubber products, we have successfully achieved a stable supply of beautiful long protectors! *For more details, please refer to our case studies or feel free to contact us.*

We received a consultation stating, 'It seems that the parts procured from overseas are about to run out; I need you to do something within a week.' Typically, production is carried out overseas, but they were unable to keep up, leading to a situation where they would run out of stock in a week. If they run out of stock, it would halt the production line of the final manufacturer, which is a situation that the parts manufacturer definitely wants to avoid. In response to this concern, since there was a spare mold in Japan, we were able to send the mold on the same day, perform the mold installation processing (to ensure it could be attached to our machines) in two days, and initiate mass production within "three business days" from the consultation. We were able to gather the required quantity within a week from the consultation and protect the supply chain. When it comes to overseas procurement, there are unique challenges such as needing to consolidate quantities due to transportation issues and difficulties in achieving the desired production volume. We can solve such concerns as well! *For more details, please download our case studies or contact us.

We often receive inquiries about whether it's possible to create 'one-of-a-kind' rubber products. In response to such inquiries, are you told, 'It's difficult without a mold' or 'The material lot doesn't match,' and then you give up? Are you paying high mold costs for prototypes, even though there's a possibility of shape changes or rejection, or are you forced to mass-produce without being able to confirm functionality? Good news for those in such situations! It is possible to create 'one-of-a-kind' rubber products and reduce the development time and costs. Rubber products are often used as 'one part of a machine.' Therefore, as development progresses, the shape or required properties may change. The solution to such concerns is prototyping rubber products through 'machining.' This is perfect for shape confirmation and functionality checks during development! We can accommodate a wide range of sizes, from small items about 3 centimeters, like those in the photo, to larger items that are about the size of both hands, and even long items around 90 centimeters. Since we do not create molds, we can reduce the lead time and costs by about 50% to 80%. *Please note that there are conditions regarding materials and compatible shapes.
