The plastic hand spray paint cap mold is a professional mold specially developed for the caps of aerosol hand spray paint cans. The formed spray paint caps need to be compatible with the valve structure of the spray paint can and have the characteristics of anti-slip and easy to press. The mold is designed with multiple parting surfaces based on the irregular structure of the spray paint cover to ensure that the pressing buttons, anti-slip patterns, nozzle interfaces and other parts are formed completely. The cavity is processed by electrical discharge machining and fine grinding, with a dimensional tolerance of ±0.05mm. The base material is made of P20S die steel after heat treatment, which has high strength and is suitable for frequent mold opening and closing. The gating system is designed with a concealed gate, which is hidden on the inner side and does not affect the appearance or usage.
