Relay Housing Injection Molds

Relay housing components manufactured via injection molding offer exceptional heat resistance (PPS material withstands temperatures of 200–220°C for extended periods), superior electrical insulation, and excellent dimensional stability, ensuring safe and reliable operation in high-temperature and high-humidity environments. The injection molding process enables the integrated formation of complex structures with high efficiency and consistent quality. Key advantages include the use of high-flow materials that faithfully reproduce intricate details while preventing defects such as short shots or air bubbles; the use of V-0 rated flame-retardant materials to effectively mitigate fire risks caused by short circuits; and a rapid molding cycle of just 25–35 seconds per shot, making it ideal for high-volume, efficient production. These components are widely used in sectors such as home appliances, automotive electronics (including automotive and engine-bay relays), industrial control systems (such as intermediate and time-delay relays), and new energy applications.
