China foundry directly supply stainless steel investment casting parts for safety switches

Product Introduction
Our stainless steel casting for safety switches are designed to fit fail-safe operation in high-risk industrial environments,engineered for safety interlock switches, industrial safety interlock keys, and actuator machine guarding switches, these components are obtained by precision investment casting with stable durability. Designed to prevent machinery accidents, unauthorized access, and system overrides. As a trusted manufacturer in safety industrial field, we deliver our solutions that protect workers, equipment, and productivity.  

1. Product Description
Our stainless steel casting for safety switches crafted from material ANC4B or 316L stainless steel, our safety switches resist mechanical stress, chemical splashes, and electromagnetic interference. Utilizing silica sol shell investment casting for tumbling or mirror polishing surfaces and lost wax casting for complex geometries, these switches feature tamper-proof housings designs,customizes in key coding, RFID integration, and force-sensitive triggers, they are ideal for hinged guard doors, assembly lines, heavy machinery,protective bonnets and hazardous situation exists.
