Injection molding

It is possible to plasticize and lighten materials in the same location!

■Injection Molding The principle of injection molding involves the process of filling a mold with rubber material that has been plasticized and kneaded by a screw within a heated cylinder at high speed and high pressure, and then curing it to create the product. This allows for the plasticization and measurement of materials to be carried out in the same location. Since injection into the mold is done at high pressure, the material that has been heated and kneaded in the screw cylinder experiences a rapid increase in temperature due to frictional heat, which shortens the curing time, making it suitable for mass production of products. Additionally, it facilitates the automation of the molding process for products with complex mold shapes or product designs. *For more details, please refer to the PDF document or feel free to contact us.*

Compression molding

Possibility of producing colorful rubber!

■What is Compression Molding? Measured rubber material is placed into the cavity of a heated mold (usually between 150°C and 180°C) and is then pressurized and vulcanized using a compression molding machine. This molding method is the most historically significant and representative method of rubber molding. *For more details, please refer to the PDF document or feel free to contact us.

Bicolor molding

High-quality two-color molded products can be produced!

■What is Two-Color Molding Two-color molding is a molding method that typically shapes different materials from a single mold, but it involves molding the same material in two separate processes. Although the number of products molded using this two-color method has decreased recently, there are still items like keypads. Additionally, our company leverages extensive experience and knowledge to assist in producing high-quality two-color molded products. *For more details, please refer to the PDF document or feel free to contact us.*

Urethane molding

We also have materials that comply with the Food Sanitation Act, so please make use of them!

■What is polyurethane rubber? Depending on how it is bonded, it can be classified into polyester (EU) and polyether (AU). The ester type is prone to hydrolysis (due to steam, heat, acid, etc.) but has excellent oil resistance. The ether type is less prone to hydrolysis but has inferior oil resistance. Typically, polyurethane (PU) is a thermosetting resin that hardens when heat is applied, so it requires a different method of mold usage compared to general thermoplastic resins. In this case, a method called casting molding is used, where pre-melted polyurethane (PU) is poured into the mold and heated to cure. There are also materials compliant with the Food Sanitation Act, so please make use of them. *For more details, please refer to the PDF materials or feel free to contact us.

Rubber sponge molding

It has a softer feel compared to rubber and can be lightweight!

■What is Rubber Sponge Molding? Rubber sponge molding involves adding a foaming agent to rubber materials to create pores in the rubber. It is formed using a mold with materials that contain the foaming agent. Unlike regular rubber, the molding process is strict and requires advanced technology and experience from mold design to molding conditions. Because it is foamed, it has a softer feel compared to rubber and can be lightweight. It also excels in sealing effects, making it suitable for applications such as sealing gaskets in areas where compression loads cannot be applied and sound-absorbing materials. *For more details, please refer to the PDF document or feel free to contact us.*
