Anchoring the“ Safety of Machinery ”Standards | Shanghai CHENZHU Strengthens the Safety Boundary with Trustworthiness and Reliability

In 2025, with the implementation of new mechanical safety standards like GB 17120-2025and GB 20905-2025, which cover 12 types of mainstream equipment including mechanical power presses, hydraulic presses, and shearing machines, mechanical safety has transitioned from an "optional configuration" to a "mandatory factory requirement." This shift is redefining what constitutes "safe machinery".

Safety is Becoming the "New Language" of Equipment

The standards for "Safe Machinery" are evolving from merely "usable" to being "reliable and compliant".

•Safety is an Access Threshold — Equipment that fails to meet standards is prohibited from leaving the factory.

•Safety is a Trust Credential — Behind accidents lie sky-high compensation and brand crises.

•Safety is a Passport for Global Trade — Compliant equipment can be sold without barriers in both domestic and international markets.

In mechanical safety control systems, safety relays act like the load-bearing structure in a building –inconspicuous yet absolutely critical.

•Emergency Stop Control — Dual-closed contact circuits ensure a reliable response when dangers occur.

•Safety Light Curtains — Real-time detection of the operational area, providing safety protection by halting machine motion (e.g., mold closing) upon human intrusion.

• Redundant Design — Conforms to the highest safety levels like ISO 13849 Category 4/PLe.

International Quality × Chinese Speed

Starting from the "Ninth Five-Year" national research initiatives to participating in the formulation and revision of 41 national, industry, and group standards(with 26 already published), Shanghai CHENZHU has witnessed the development trajectory of industrial safety standards.

‘Reliability is the Bottom Line’

-100% independent R&D, supported by 160 valid patents.

-CNAS-certified laboratory.

-Compliance with 8 international certifications including CE, UL, and TÜV.

-5-year warranty coupled with product liability insurance, adding an extra layer of security.

‘Trustworthiness is a Responsibility’

From tunnel boring machines and wind power equipment to automotive production lines and semiconductor manufacturing—CHENZHU's safety relay shave become deeply embedded in various high-end manufacturing scenarios, acting as the fundamental safeguard for equipment safety.

‘Sustainability is a Commitment’

-Engineer support with 24-hour response.

-Capability to provide customized safety solutions.

For compliant machinery, safety is not just the baseline but the starting point. As "Made in China" moves from "scale expansion" to "value competition," safety is transforming from a cost center into a core asset. Leveraging over two decades of technical expertise, CHENZHU continues to deepen its focus on functional safety and mechanical safety, driving the ongoing advancement of domestically produced safety relays and control modules to build a trustworthy safety foundation for China's manufacturing sector.

Compliant machinery must be safer.

CHENZHU–safeguarding begins with safety control.
