Here is the process of creating rigid polyurethane molded products. First, please let us know the overall shape, size, and the "form" you want to express, even if it's just a sketch or rough drawing. We can produce original made-to-order products starting from about 50 pieces. After that, we will create a master model, produce a prototype, and once the prototype is approved, we will move on to mass production. Everything is made to order. 【Process】 ■STEP1: Shape ■STEP2: Quantity ■STEP3: Prototype ■STEP4: Mass Production *For more details, please download the PDF or feel free to contact us.

• Hard urethane foam

Rigid polyurethane does not use molds for shaping. First, a master model (the product to be made) is created using a wooden model or similar, which is then used to make a silicone rubber mold, and mass production is carried out using that silicone rubber mold. Therefore, the costs for molds only require the initial expenses for creating the master model and the costs for producing the mold frame to make the silicone rubber mold. [Reasons for Low Mold Costs] ■ Only the initial costs for producing the mold frame are required ■ The silicone rubber mold costs are consumables, so they are amortized through the product cost based on the production lot *For more details, please download the PDF or feel free to contact us.

• Hard urethane foam

We would like to introduce the rigid urethane that our company handles. It is a polymer (plastic) generated by mixing and reacting two main raw materials (polyol/isocyanate).
