Investment Casting Audible and Visual Alarm
Our investment casting audible and visual alarm parts are manufactured using silica-sol precision casting, followed by 5-axis CNC finishing. This hybrid process guarantees tight tolerances (±0.05 mm), excellent surface finish (Ra 1.6), and superior corrosion resistance. Each unit is pressure-tested to 1.5 MPa and IP66-rated for dust- and water-tight performance.
Key Features
Advantages & Benefits
Investment casting allows complex geometries-such as internal cooling fins and acoustic chambers-without secondary assembly. The result is a lighter, stronger investment casting audible and visual alarm enclosure that reduces installation time and lowers total cost of ownership by up to 18 % compared to sand-cast equivalents.
