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. For more details, feel free to contact us.

In rubber products, recycled rubber, which is made by recycling materials like used tires, may be used. The advantages of using recycled rubber include "being sustainable as it is a recycled product" and "lower cost compared to regular rubber materials." However, there were concerns that "mixing inexpensive recycled rubber to reduce costs did not work well," resulting in "twice the usual molding time" and "an increase in defects." Upon investigation, it was found that "the curing time for the rubber was taking more than twice as long" and "gas release was becoming worse." The properties of recycled rubber can vary significantly depending on the quality of the rubber before recycling, and this tendency is more pronounced in lower-grade, inexpensive products, making it difficult to maintain consistent quality. Therefore, when we used recycled rubber that had a proven track record in our company, we were able to achieve "normal curing times" and "a significant reduction in defects."

In the manufacturing process, there are often needs such as "not wanting to conduct electricity," "wanting a firm grip," and "wanting to prevent oil and water leaks." For these reasons, "rubber" is often used. On the other hand, that "rubber" is also frequently used in environments exposed to ultra-high concentrations of acidic chemicals or organic chemicals, as well as high and low temperatures. As a result, issues arise such as, "It becomes ragged in a week, rendering the rubber useless," and "Despite not wanting to conduct electricity, it ends up conducting electricity, leading to a mountain of defects." We will solve such problems. *For more details, please refer to our case studies or feel free to contact us. Shinei Rubber Industry primarily manufactures and sells rubber products ranging from hand-sized to over one meter. <What Shinei Rubber Industry can do> - Rubber material formulation design: Creating rubber recipes to meet required standards. - Material mixing and prototype molding: Confirming consistency with required standards and stability during mass production transition. - Mass production with specified formulations: Establishing mass production processes based on predetermined formulations. - Transfer-type acceptance: Responding quickly to the transfer of fluid products (with transfer achievements in as little as one week).

When it comes to rubber products, the image of "black" is quite strong. This is because carbon black, a "black" reinforcing agent, is added to the rubber, making it "black." This carbon black is a very important chemical for strengthening the rubber. However, we often receive inquiries about wanting to color the rubber in various colors such as "white" or "red." One representative example is a baseball "base." The baseball base is "pure white." We use rubber materials that are "pure white." If dust or the commonly used "black" carbon black gets mixed into the materials during the mixing stage, or if it adheres to the materials after mixing, the color of the materials can change instantly. Even during the molding stage, the color of the product can change due to dust or dirt on the mold. Additionally, if the product gets sunburned after molding, it can turn brown, so caution is necessary. *For more details, please download the case study from the link below or contact us.*

"I would like just one rubber product for functionality and shape confirmation." "I don't know yet if we will mass-produce, but we can't move forward without creating a prototype and confirming its functionality." "We are developing rubber products by making molds for prototypes, but it takes time and costs money." We often receive such concerns. In this case, we were able to significantly reduce costs by 80% and shorten the delivery time from 2 months to 2 weeks. For more details, please refer to the catalog.

As the new coronavirus has transitioned to Category 5 and economic activities have returned to normal, the labor shortage has become serious. I believe many in the manufacturing industry are facing similar concerns. Amidst this, we received an SOS consultation stating, "We have many orders, but we can't produce because we don't have enough people." If this continues, there will be delays in delivery, which will significantly impact the supply chain... 【Immediate response with mold transfer!】 Our team rushed to the site, checked the actual products and molds, made slight changes to the installation specifications, and temporarily transferred the molds to our company. After the transfer, we rapidly conducted backup production. We have a proven track record of handling sudden mold transfers, which allowed us to respond effectively! For more details, please download the catalog.

We received the request to 'want to add a yellow mark to make part of it stand out' and 'want it to be integrally molded so that the mark cannot be removed.' When it comes to integrally molding, the key point to pay attention to is 'ensuring that the black rubber does not cover the yellow mark area.' To clear this point, it is necessary to thoroughly develop the following two aspects: 1. The mold for shaping 2. The method of incorporating the rubber material During the prototype stage, there were instances where the black rubber covered the yellow mark or the yellow mark was misaligned, making it difficult to achieve successful integral molding. However, by repeatedly improving the method of incorporating the rubber material, we were able to eliminate misalignment and rubber coverage. For more details, please download the catalog.

"Rubber has good grip and elasticity, which is great, but compared to a similar material, 'resin,' it tends to be more expensive..." That's because there is a significant difference in the "method of production." Making rubber is, in a nutshell, similar to "making bread"! Resin is a "thermoplastic" that solidifies when cooled, allowing for quick molding, whereas rubber, like bread, is a "thermosetting" material that requires baking, making it more labor-intensive. Just like with bread, there are many commonalities, such as kneading and aging... Additionally, one of the characteristics of rubber is that it allows for formulation design tailored to desired properties, enabling precise control over the final product. Currently, our company is distributing a free resource that explains rubber production by comparing it to bread-making, titled "Encyclopedia of Rubber Production." We support your manufacturing endeavors!

I don't really understand about rubber... Are you choosing the type of rubber "somehow"? Even though I just replaced it the other day, it's already deteriorated... It's a hassle to replace it, so I wish there was a solution... To solve such concerns, we need to consider the purpose of using the rubber (the effect you want to achieve the most) and the usage environment. There are many types of rubber. There are rubbers that are resistant to deformation, rubbers with grip, rubbers that are weak to heat, and rubbers that dissolve in oil... On the other hand, the environments in which rubber is used are varied. 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. We will support you in choosing the optimal rubber with our easy-to-understand visual material "Rubber Type List by Desired Function"!
