What is Polyurethane?
Polyurethane Rubber Casting
Polyurethane rubber casting is an important and precise process in which polyurethane materials are poured into special molds in a liquid form, so that after cooling, it becomes the desired shape. This process includes several main steps: 1. Preparation of raw materials: First, polyol and isocyanates are prepared as raw materials. These materials must be weighed and measured with high precision so that the final composition has desirable mechanical and chemical properties. 2. Composition and mixing: In this step, the raw materials are combined with each other. This combination should be done uniformly and homogeneously so that the final product is of high quality. Special equipment is used to perform this process, which has high precision. 3. Casting: After mixing the ingredients, the liquid mixture is poured into special molds. Molds can be designed in different ways depending on the type of final product. At this stage, precision in temperature and pressure control is very important so that the final product is produced without defects. 4. Curing and drying: After casting, polyurethane parts must be cured and dried at a specific temperature to reach their final mechanical properties. This step requires time and precision to ensure the final quality of the product.
