No mold required, - Suitable for small lots and prototypes - Capable of handling complex shapes.
Rubber cutting processing is a method of finishing rubber materials into the desired shape by cutting or trimming, suitable for prototyping and small-scale production without the use of molds. Main methods of rubber cutting processing: - Lathe processing A method that involves rotating the rubber material while applying a cutting tool to trim it. It is suitable for cylindrical shapes and processing of inner and outer diameters. - Milling processing A method that uses a rotating cutting tool to trim flat surfaces or grooves. It allows for processing such as steps and chamfers. - Water jet processing A method that cuts rubber using a high-pressure water stream. Since it does not apply heat, it causes minimal damage to the material and can accommodate complex shapes. - Hand lathe processing A method where a craftsman manually applies a cutting tool to the rotating material. It requires high skill but allows for fine adjustments. - Drilling processing A method that creates holes using a drill. It is mainly used for creating through holes or hollow structures. - Cutting processing A method that cuts the material linearly with a cutting tool. It is suitable for sheet-like rubber. - Adhesive processing Rubber is soft and elastic, which poses challenges in achieving dimensional accuracy. It is common for tolerances to be accepted depending on the application. For more details, please contact us or download the catalog.
