We would like to introduce a case study of the production of "urethane rubber tires with hardness of 90 degrees and 80 degrees." Urethane rubber tires with a hardness of 90 degrees have quite a bit of stiffness, making them difficult to remove easily. Therefore, we utilized the technology we have developed through previous urethane rubber casting to successfully demold the urethane rubber tires with a hardness of 90 degrees. 【Case Overview】 ■Product Name: Urethane Rubber Tires 90 Degrees and 80 Degrees ■Processing: Casting (using urethane rubber molds) ■Production Period: 1 week (4 pieces) *For more details, please refer to the PDF document or feel free to contact us.

Here is a case study of the production of "Caster Roller." We found a jig that can handle nearly 20 pieces at once for shot blasting, allowing for a smooth execution of both shot blasting and adhesive processing. We designed the mold so that the protruding parts of the metal fittings would be on the bottom, and with a urethane rubber hardness of 90 degrees, we achieved good compatibility with the grinding wheel, enabling smooth grinding and polishing processes. 【Case Overview】 ■ Product Name: Caster Roller Urethane Rubber 90 Degrees Black ■ Processing: Casting (with mold) + Urethane Rubber Grinding and Polishing ■ Production Period: Approximately 1 month (160 pieces) *For more details, please refer to the PDF document or feel free to contact us.

Here is an example of the production of a "press roll." Since it is a single item tailored to specific needs, a general-purpose mold was used. The casting was aimed at a size that makes subsequent processes easier. In the urethane rubber grinding and polishing process, the hardness is 90 degrees, allowing for relatively smooth processing. [Case Overview] ■Product Name: Press Roll Φ163×Φ143×70L (Rubber Function 50L) ■Processing: Urethane Rubber Casting + Urethane Rubber Grinding and Polishing ■Production Period: 10 days (2 pieces) *For more details, please refer to the PDF document or feel free to contact us.

Here is a case study of the production of "Chuck Jaws." This product has only 0.5mm of urethane rubber lining. If too much urethane rubber is lined during the casting process, there is a possibility that it could peel off during the grinding and polishing process. Therefore, by also lining the area around where the urethane rubber is applied, we achieved a stronger lining capability. We put a lot of thought into the urethane rubber casting. [Case Overview] ■ Product Name: Chuck Jaws ■ Processing: Urethane Rubber Casting + Urethane Rubber Grinding and Polishing (Milling Machine) ■ Production Period: 1 Week *For more details, please refer to the PDF document or feel free to contact us.

Here is an example of the production of "2T urethane rubber lining." Due to the year-end workload, this request prioritized delivery time. We accurately identified the areas to be lined with urethane rubber and implemented thorough masking to ensure that the blasting did not affect other areas. After that, we searched for available molds (general-purpose molds) to ensure that the 2T urethane rubber lining was accurately realized. [Case Overview] ■ Product Name: Claw Urethane Rubber Lining ■ Processing: Castable Urethane Rubber Lining Claw ■ Production Period: 3 Days *For more details, please refer to the PDF document or feel free to contact us.

Here is an example of the production of a "male downward feeding roller." Due to the urethane rubber hardness of 55 degrees, we aimed for that hardness and carried out urethane rubber casting. Achieving a urethane rubber formulation that targets 55 degrees is quite challenging, but with our experience in liquid casting urethane rubber, we were able to precisely achieve the desired hardness of 55 degrees while considering the isocyanate of the urethane rubber raw materials. [Case Overview] ■ Product Name: Male Downward Feeding Roller 55 Degrees Φ72.7×Φ63×30W ■ Processing: Urethane Rubber Casting (General Type) + Grinding and Polishing ■ Production Period: 5 Days (5 Units) *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of the production of "Drive Rollers." The company that was processing urethane rubber went out of business, and we received the request. We manufactured a simple mold in-house. The tolerance of Φ16.24+0.05-0 is challenging, and the shaft measuring 390L×Φ6 falls into the category of being elongated. However, such grinding and polishing processes were previously outsourced to suppliers before 2010, so being able to do this in-house now is a significant step forward. 【Case Overview】 ■ Product Name: Drive Roller ・ Φ16.24×15×2 locations ■ Processing: Casting (with mold) + Urethane Rubber Grinding and Polishing ■ Production Period: 2 weeks *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of the production of a "transfer roller." The outer diameter of the urethane rubber is finished at Φ25, and when performing grinding and polishing on the urethane rubber, having as little excess material as possible is advantageous for subsequent processing. Therefore, it is important to search for general-purpose molds (available ones), which leads to a reduction in delivery time. Our company has a high level of expertise in searching for and producing general-purpose molds, resulting in a beautiful finish. [Case Overview] ■ Product Name: Transfer Roller - Urethane Rubber Hardness: 30 degrees, Φ25×Φ15×254L (537L) ■ Processing: General-purpose mold urethane rubber injection + grinding and polishing ■ Production Period: 2 weeks *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of the "Polishing Container with Inner Diameter Urethane Rubber Lining." Since it involves urethane rubber lining on the inner diameter of the core, the key point in production is to consider how to prevent peeling. We implemented a combination of shot blasting and adhesion techniques. Additionally, cutting the casting surface was not easy due to the wobbling that occurs when the lathe is rotated, but a skilled craftsman handled it. 【Case Overview】 ■Product Name: Polishing Container with Inner Diameter Urethane Rubber Lining ■Processing: Casting (with mold) + Casting Surface Cutting ■Production Period: 2 weeks *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of the production of the "Feeding Roller (Woodworking Edition)." We received a request for the replacement of a urethane rubber roller. We confirmed the hardness, shape, and appearance of the sample feeding roller through visual inspection, a durometer, and calipers, and then proceeded with the urethane rubber processing. The hardness of the urethane rubber was determined to be 80 degrees, which is suitable for feeding, and we made adjustments to minimize internal heat generation during roller friction. [Case Overview] ■ Product Name: Feeding Roller (Woodworking Edition) ■ Processing: Casting (without mold) + polishing and grinding ■ Production Period: 1 week to 10 days *For more details, please refer to the PDF document or feel free to contact us.
