Product introduction
The PVC ball valve mold is the core equipment for injection molding PVC ball valves. PVC ball valves are widely used in building water supply and drainage, agricultural irrigation, chemical pipelines, and sewage treatment systems due to their corrosion resistance, light weight, and low cost. This mold is made of high-quality mold steel (such as P20, 718H, or H13) and undergoes quenching, tempering, and surface nitriding treatment, providing good wear resistance and corrosion resistance, with a long service life.
The mold structure design is reasonable, including key components such as cavity, core, slider, and ejection mechanism. The cavity and core are processed by precision EDM and CNC engraving to ensure the ball and valve body fit tolerance is controlled within ±0.02mm. The slider mechanism is driven by an angled guide pin or hydraulic drive, with smooth action to ensure accurate ball core molding position. The gating system adopts hot runner or cold runner design, with optimized gate position to reduce weld lines and air traps, improving product density. The cooling system uses conformal cooling channels to ensure uniform heat dissipation and shorten the molding cycle.
According to customer requirements, single-cavity or multi-cavity molds (such as 2-cavity, 4-cavity, 8-cavity) can be designed to meet different production volumes. For special specifications of ball valves (such as DN20-DN63), the mold base size and ejection layout can be customized. The draft angle of the mold is calculated to ensure easy demolding without deformation. Surface roughness can reach Ra0.4μm, giving the finished product a high gloss appearance.
In terms of safety, the mold is equipped with positioning pins, limit switches, and protection devices to prevent operational errors from damaging the mold. Strict mold testing is performed before delivery, including dimensional inspection, sealing test, and injection parameter debugging, ensuring it is ready for use upon delivery. This mold complies with ISO 9001 quality management system and comes with a 12-month free warranty.
Application examples include: PVC ball valve bodies for irrigation systems, requiring a pressure resistance of 1.6MPa; ball valves for building drainage systems, requiring acid and alkali resistance. Based on the customer's 3D drawing or sample, a one-stop service from design to mass production can be provided.
