Fluororesin is made from a rare stone called fluorite. It possesses strong characteristics such as heat resistance, chemical resistance, electrical insulation, non-stick properties, and slipperiness, making it suitable for use in various forms in harsh environments and specialized fields. Utilizing these features, it plays an important role in everyday items like cooking utensils, as well as in cutting-edge industries such as semiconductors, chemicals, electronic machinery, batteries, medical applications, aerospace, and space exploration. 【Features】 ★ Heat resistance ★ Chemical resistance ★ Wear resistance ★ Non-stick property ★ Electrical insulation ★ Weather resistance

What is the molding of fluororesin materials? The molding of fluororesin (mainly PTFE) refers to the process of forming materials such as "rods, sheets, and special shapes" used for machining and secondary processing by applying pressure and sintering powdered raw materials. The density of the material and the presence of internal defects (voids) significantly affect the machinability of subsequent processes and the quality of the final product. Direct Pressure Compression Molding Direct pressure compression molding is a method where PTFE powder raw material is filled into a cylindrical mold and shaped by applying pressure directly from above. It is suitable for relatively large-sized materials and simple shapes, and is characterized by ease of size and shape adjustment. It is widely used as a general-purpose material for rod and block materials for machining. Isostatic Molding Isostatic molding is a molding method that applies uniform pressure to the entire raw material using water pressure (hydrostatic pressure). Due to the uniform pressure application, it is less likely to produce internal density variations or voids, enabling the molding of strong, void-free materials. It can also accommodate materials for high-quality products such as thin-walled shapes and container shapes, as well as special shapes that are close to the final form.

What is cutting processing of fluororesin? Cutting processing of fluororesin (such as PTFE and PFA) refers to a machining method where molded materials are machined using equipment like NC lathes and machining centers to finish them into product shapes. A significant feature is that it does not require molds, making it suitable for prototyping, small lots, and diverse production. It offers high freedom of shape and can accommodate a wide range of applications, including bellows, diaphragms, sealing parts, and precision components. Support for cutting processing of filled PTFE "Filled PTFE," which incorporates fillers such as carbon fiber, fiberglass, and graphite into PTFE, is a high-performance material with improved wear resistance, creep resistance, and sliding properties. Our company flexibly supports the cutting processing of these filled PTFE materials and proposes optimal processing tailored to specific applications. Cost and material loss reduction through shaping processing Our company also accommodates shaping processing, which involves forming materials into shapes close to the final product during the molding stage. If the shape allows for shaping processing, benefits such as "significant reduction in material loss," "shortened processing time," and "reduction in costs and delivery times" can be expected.

What is injection molding of fluororesin? Injection molding of fluororesin (such as PFA, PVDF, ETFE) is a molding method where melted resin is injected into a mold, cooled, and solidified to create the product shape. It is characterized by excellent reproducibility of complex shapes compared to machining, minimal dimensional variation, and high mass production capability. It can accommodate everything from small parts to large molded products and is used in a wide range of applications, including semiconductor manufacturing equipment parts and piping components. Insert molding Insert molding is a molding method where metal parts are set in the mold in advance, and then fluororesin is injection molded over them, integrating the resin and metal. By integrating screw sections and metal cores, it enhances the strength and durability of the product while imparting chemical resistance and low friction properties to the surface of the fluororesin. Resin flow analysis In resin flow analysis, the flow and filling state of the resin inside the mold are simulated in 3D, allowing for the prediction of flow patterns, resin pressure distribution, temperature distribution, and weld line occurrence locations in advance. By identifying issues before mold production, it is possible to prevent molding defects and rework, enabling the creation of stable molded products in a short period and at low cost.
