In the "Twisted Shape Products," we have introduced various products to the market through our uniquely developed molds and production technology. Extrusion molding is a production method for creating linear products, but by twisting these products, we have made it possible to add functionality. In recent years, we have primarily produced twisted products with complex cross-sectional shapes made of ABS resin as an alternative to aluminum components. This transition has achieved weight reduction. 【Features】 ■ Uniquely developed molds and production technology ■ Primarily producing twisted products with complex cross-sectional shapes made of ABS resin as an alternative to aluminum components ■ Achieved weight reduction by switching from aluminum components ■ Thorough dimensional management *For more details, please refer to the PDF materials or feel free to contact us.

This product is a crucial component known as "seal material," used in industrial products called linear guides, which prevents the intrusion of dirt and dust. The sizes of seal materials vary, but the smallest ones are only 3mm wide, making it very difficult to perform extrusion molding due to their low discharge volume. To achieve fine two-layer molded products, our company has introduced a small extruder with a screw diameter of only 15mm. Furthermore, by innovating the mold structure, we have been able to achieve mass production. [Features] - Achieved two-layer molded products with a width of 3mm - Introduced a small extruder with a screw diameter of only 15mm - Achieved mass production by innovating the mold structure *For more details, please refer to the PDF document or feel free to contact us.

This product uses AES resin, which has excellent weather resistance. AES resin has essentially the same properties as ABS resin, but it excels in outdoor weather resistance and UV protection, and does not suffer from weathering degradation, so coatings are unnecessary. It can prevent discoloration and fading, allowing for long-term outdoor use. Please feel free to contact us if you have any inquiries. 【Features】 ■ Excellent outdoor weather resistance and UV protection ■ No need for coatings as it does not suffer from weathering degradation ■ Prevents discoloration and fading ■ Allows for long-term outdoor use *For more details, please refer to the PDF document or feel free to contact us.

The main concern regarding resin products used outdoors is weathering discoloration caused by ultraviolet rays from the sun. Our company has successfully leveraged our unique material technology, developed over many years, to dramatically improve the weather resistance of our products. Even after 3,000 hours of exposure in accelerated weathering tests (Xenon weather meter), there is almost no discoloration observed in the test specimens. Fence panels are typically manufactured using single-layer extrusion, but we have made it possible to create products with high weather resistance while keeping costs down by thinly coating the substrate with this ultra-weather-resistant resin through a two-layer molding process. This technology is also expected to be applicable to outdoor resin products other than fences. 【Features】 ■ Dramatically improved weather resistance ■ Almost no discoloration observed in test specimens even after 3,000 hours of exposure in accelerated weathering tests ■ Cost reduction achieved by thinly coating the substrate through two-layer molding *For more details, please refer to the PDF document or feel free to contact us.

Extrusion molding is a method of continuously shaping resin that has been heated and melted, then cooled and solidified with air or water. While injection molding cools the resin inside a mold, extrusion molding passes the heated and melted resin through a mold from the heating cylinder of the extruder, and then gradually cools it to shape. Because of this method, products with a consistent shape are continuously formed. Raw resin is fed into the extruder, heated and melted, extruded from the mold, and the extruded molten resin is cooled, collected, and cut. These processes allow for the continuous production of items with the same cross-sectional shape. 【Features】 - Heats and melts resin, then cools and solidifies it with air or water for continuous shaping. - Products with a consistent shape are continuously formed. - A consistent production system from design to secondary processing. - Capable of producing products with short lead times, high functionality, and high quality. - Suitable for products with linear shapes and various lengths, as well as products with handles or deep designs. *For more details, please refer to the related links or feel free to contact us.*
