What is Urethane casting? Urethane casting is a manufacturing process similar to injection molding where urethane resin is cast in a cavity between two silicone mold halves. The process replicates a master model by pouring a silicone mold around it. In a highly skilled procedure, the mold is sliced into two halves, the master model is removed, and then a gating and ventilation system is added. Subsequently, the model maker casts a urethane-based resin into the resulting cavity and cures it under a vacuum to prevent air bubble intrusion. Vacuum casting is better known as urethane casting or polyurethane casting in the US. Vacuum Casting Process Step 1: Master Building Masters represent 3D solids derived from your CAD designs. Typically crafted via CNC machining or 3D printing, they are meticulously fabricated under controlled conditions, often at 40°C. Once the masters are meticulously finished and thoroughly inspected, the next phase involves progressing to silicone mold creation. Step 2: Mold Making The creation of casting molds commences with liquid silicone. The casting box is partially filled with this liquid silicone, and then subjected to controlled heating until the silicone is fully cured. Following this, the mold undergoes a 16-hour curing process within an oven. Additional batches of heated silicone are poured to complete the mold, ensuring comprehensive coverage. Once fully dried, the mold is carefully cut open to extract the master component. Step 3: Part Production Production of parts begins by pouring casting resins into the emptied mold cavity. This process results in the creation of highly precise replicas of the original master. The flexibility extends to the possibility of overmolding with multiple materials. Typically, silicone molds maintain their effectiveness for approximately 20 reproductions of the initial pattern. This structured approach ensures the replication of intricate designs with fidelity and efficiency, leveraging the precision of CAD designs and the versatility of silicone molding techniques.

The UV laser solidifies the resin in the desired shape, creating highly detailed and accurate prints with smooth surface finishes. SLS (Selective Laser Sintering)/DLP (Digital Light Processing) SLS and DLP are similar processes that use a laser or projector to selectively solidify a powdered material, such as nylon or resin, layer by layer. The excess powder acts as a support structure during printing, making it ideal for complex geometries and intricate designs. SLS uses a laser to selectively sinter powdered materials, such as nylon or other engineering-grade plastics, layer by layer. This results in parts that are durable, heat-resistant, and have a high level of mechanical strength. SLS is commonly used in industries such as aerospace, automotive, and medical for producing functional prototypes and end-use parts that require high physical strength and robustness. FDM (Fused Deposition Modeling)/LCD (Liquid Crystal Display) FDM and LCD are popular 3D printing processes that use thermoplastic filaments or liquid resin, respectively, to create objects layer by layer. In FDM, the filament is heated and extruded through a nozzle, while in LCD, the liquid resin is cured using UV light. Both processes are widely used for rapid prototyping and producing functional parts. DMLS Direct Metal Laser Sintering (DMLS): In DMLS, a high-powered laser selectively fuses metal powder particles together, layer by layer, to create a solid 3D object. The process is similar to Selective Laser Sintering (SLS) for plastics but specifically designed for metal materials. DMLS can produce complex geometries and parts with high strength and durability, making it suitable for aerospace, automotive, and medical applications. SLM Selective Laser Melting (SLM): Selective Laser Melting is another metal 3D printing process that uses a laser to fully melt metal powder particles, creating a dense and fully consolidated part. SLM offers high precision and the ability to produce parts with excellent mechanical properties, making it suitable for producing functional metal parts for various industries. Both DMLS and SLM are commonly used in industries where high-strength metal parts are required, such as aerospace, automotive, and medical. These processes offer the ability to produce complex geometries and parts with excellent mechanical properties and performance. https://www.thingyfymfg.com/

The OS&Y stem is most popular, but Non-Rising Stem type is also in our scope. Both flexible and Solid disc are available. For big size or Big pressure valve, By-pass design is optional.Below seal gate valve also falls in our ability. A gate valve, known as a sluice valve, is a valve that opens by lifting a barrier (gate) out of the path of the fluid. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low flow resistance. The size of the open flow path generally varies in a nonlinear manner as the gate is moved. This means that the flow rate does not change evenly with stem travel. CAST STEEL GATE VALVE-DIN is usually for working condition in which the valve is not opened or closed frequently, and supports gate fully open or fully closed. It’s not suitable for adjustment or throttling. Gate valve includes three types-Wedge gate, Knife Gate and Parallel Gate. The disc of Wedge gate valve comes with Solid Type and Flexible Type. Flexible Wedge Gate Valves design consists of two independent and flexible wedge halves, that allow a relative movement to accommodate changes in the body seat angles. Solid wedge is designed in one-piece model while flexible wedge offers a wedge shape for both seats.
