We flexibly respond to the machining of filled PTFE. PTFE has excellent properties such as "heat resistance, chemical resistance, electrical insulation, non-stickiness, and low friction," but depending on the application, it may exhibit weaknesses such as "susceptibility to deformation, fragility, and wear." Therefore, by adding fillers such as carbon fibers or graphite to PTFE, we enhance its properties while improving: ★ Wear resistance ★ Creep resistance ★ Sliding characteristics ★ Mechanical strength This is the filled PTFE material. 【Do you have any of these concerns?】 - PTFE products are prone to deformation and breakage - Rapid wear leads to a short lifespan of parts - Creep occurs under load - Wear or seizure occurs at sliding parts - You want to utilize PTFE's properties but also need strength 【Benefits of Fillers】 - Improved wear resistance allows for longer-lasting parts - Enhanced creep resistance ensures reliability even in load-bearing applications - Improved sliding characteristics enable stable operation - The inherent chemical resistance, heat resistance, and low friction of PTFE remain intact If you let us know your application, we can provide the best proposal.

We support the production of composite parts that integrate fluororesin and metal components. By combining the excellent chemical resistance and low friction properties of fluororesin with the strength of metal, we achieve an optimal structure for parts used in harsh environments, such as semiconductor manufacturing equipment and chemical apparatus. ■ PFA Integration of resin and metal through injection molding (insert molding) By setting the metal components in the mold in advance and injecting PFA resin, we produce a monolithic molded product that encapsulates the metal components. ■ PTFE Integration of resin and metal through material molding application (isostatic molding) By applying the molding process of powdered PTFE and molding it with the metal components incorporated, we achieve a structure that integrates PTFE and metal. 【Are you facing any of these issues?】 - The strength of resin alone is insufficient, and you want a structure integrated with metal. - You want to coat metal components with fluororesin to provide chemical resistance. - You want to produce parts with a monolithic structure instead of using adhesives or assembly. - You want the parts that come into contact with chemicals to be made of fluororesin. - You want to use low-friction resin for parts where friction occurs. - You are considering monolithic molded products with mass production in mind.

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.

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.

The three processes that are typically handled by separate companies—material manufacturing, processing, and molding—are completed by a single company. By conducting everything from material creation to processing and molding in-house, we can respond flexibly and swiftly to needs ranging from prototyping and small-scale production to mass production. Meiko Industry's "Three Manufacturer Functions" ★ Material Manufacturer Function This process involves compressing powdered fluororesin raw materials at high pressure and sintering them to produce rod-shaped fluororesin materials. While many processing manufacturers procure materials externally, Meiko Industry manufactures the materials itself. ★ Processing Manufacturer Function We perform processing such as cutting, slicing, and hollowing on the rod-shaped materials we manufacture in-house, finishing them into products tailored to specific applications and specifications. Our deep understanding of the material's characteristics allows us to achieve high-precision and high-quality processing. ★ Molding Manufacturer Function We melt bead-shaped fluororesin raw materials, pour them into molds, and cool them to solidify, efficiently mass-producing products of the same shape. This method excels in quality stability and reproducibility during mass production, offering cost advantages as well.
