Urethane rubber is a type of plastic, simply put, it is "plastic that has rubber-like elasticity." The urethane rubber we handle comes in two types: "Mirable Urethane Rubber" and "Liquid Urethane Rubber." "Mirable Urethane" is a product made from solid materials that are the same as those used in common rubber. "Liquid Urethane Rubber" is, as the name suggests, a product made from liquid raw materials. For more details, please refer to the product page or the catalog page.

Our company conducts all processes from core processing of rubber rollers to rubber mixing, molding, and grinding, providing integrated production, sales, and services for rubber rollers. Here is a list of the physical properties of rubber. The aging properties section contains actual measured values from aging tests. *Please note that these are measured values and do not guarantee performance. [Excerpt of Physical Properties] ■ Liquid urethane ether type - natural color ■ Liquid urethane ester type - natural color ■ EDPM - black ■ EDPM - gray For more details, please refer to the product page or the catalog page.

The financial terminals compatible with the new banknotes have been decided to be equipped. They are resistant to wear and have high precision. This reduces the frequency of replacements and lowers running costs. Our company manufactures high-quality "liquid urethane rubber rollers." We have had a long-standing relationship with financial terminal manufacturers, and it has been decided that our products will also be used in terminals compatible with the new banknotes. Our products are adopted in many overseas products and have received high evaluations in terms of quality. This evaluation is based on the low occurrence of troubles and the aspect of running costs. For more details, please refer to the product page or the catalog page.

We can handle all processes from core processing of rubber rollers, rubber mixing, molding, to polishing in a one-stop manner. Rubber rollers are commonly used in industrial equipment, but not much is known about the equipment used to create them. Therefore, we would like to introduce some of our equipment. At our company, we change our equipment according to the type of rubber, and we can also accommodate metal processing, allowing us to create high-precision products through core processing calculated from the completed design of the rubber roller. In particular, liquid urethane has received high praise from our clients. For more details, please refer to the product page or the catalog page.

Proposal for changing rubber types according to usage. ■ Improvement Examples - Softening the hardness of the rubber - Changing the thickness of the rubber For details, please refer to the product page or catalog page.

Our developed rubber material is being used and widely adopted in existing models. Duplo Seiko Co., Ltd. develops cutting machines and printing machines tailored to customer needs, both domestically and internationally, from Wakayama Prefecture, and in this context, Towa-made parts are playing an active role. The company has been concerned about the severe wear of the feeding rollers in their printing machines and has been seeking durability, as well as worrying about back transfer due to slip marks. Therefore, we proposed the "wear-resistant EPDM" that we developed in the past. They conducted prototype evaluations. For more details, please visit the product page or the catalog page.

Are you struggling with issues related to defective rubber rollers? ■ Causes of Problems - Defective core material - Defective rubber, etc. In general, the manufacturing of rubber rollers often involves core materials that are supplied or purchased from external sources. As a result, when problems occur, it can be difficult to investigate thoroughly, and it may not be immediately clear whether the issue is with the core material or the rubber, leading to unexpected costs and time delays. ■ Improvement Measures Our company offers integrated in-house production from core material selection to rubber processing. For more details, please refer to the product page or the catalog page.

Are you considering measures due to the soaring raw material costs? Here are some examples of improvements in rubber rollers. 【Situation/Challenge】 Company D was experiencing severe wear on the feed rollers of their printing machines and desired greater durability, while also being concerned about back transfer due to slip marks. 【Improvement Measures】 Therefore, we proposed our previously developed 'wear-resistant EPDM'. They conducted prototype evaluations. For more details, please refer to the product page or the catalog page.

Our company handles the entire process from core processing of rubber rollers to rubber mixing, molding, and polishing, featuring a consistent production of rubber rollers. Are you experiencing issues such as rough marks remaining on processed shafts or difficulty in polishing the surface? We have solutions to share. We will discuss the stabilization during the adhesion of rubber to shafts, including challenges and solutions. For more details, please refer to the product page or the catalog page.
