Lingyufab (Shanghai Lingyu Industrial Co., Ltd.), established in 2003, stands out as a premier manufacturer of machine guards and safety enclosures. With over 20 years of experience in precision sheet metal fabrication, we offer comprehensive solutions from 1-piece prototyping to large-scale production. Our facility is equipped with advanced laser cutting systems, CNC bending centers, stamping presses, welding stations, and powder coating lines. As a Mitsubishi Electric certified core supplier adhering to Japanese quality standards, we serve clients across industrial automation, robotics, packaging machinery, material handling, and manufacturing sectors.

As a China-based manufacturer located in Shanghai, Lingyufab leverages the region's robust supply chain and skilled workforce to produce high-quality machine guards and safety enclosures at competitive prices. We adhere to ISO 9001:2015 quality management system. Our in-house production eliminates outsourcing costs, delivering 15 to 20 percent cost savings to customers. We support 1-piece samples, 100-piece pilot runs, and high-volume mass production with monthly output exceeding 5,000 units.

Our machine guards and safety enclosures are engineered to precise specifications. Materials include carbon steel, stainless steel (304 and 316), and aluminum profiles. Standard panel heights range from 1000mm to 2660mm, with widths from 200mm to 1500mm. Mesh panels feature 20×100mm openings with 3mm wire diameter, and allow impact energy up to 750J. Perforated steel sheet options include 2.0mm to 4.0mm thickness with hole diameters from 8mm to 20mm for ventilation and visibility. Surface finishing options include powder coating with any RAL color, electrostatic coating, anodizing, and zinc plating available upon request. Compliance with ISO 13857 (safety distances) and ISO 13855 (positioning of safeguards) is standard.

Lingyufab specializes in producing custom machine guard and safety enclosure parts including fixed machine guards, interlocking guards with safety sensors, perimeter fencing systems, wire mesh panels, perforated metal sheets, aluminum profile frames, robotic cell enclosures, access doors (swinging, sliding, and bifold), and modular fencing systems. Each part is tailored to your specific machine configuration, safety requirements, and facility layout. Our engineering team provides upfront technical support, including safety distance calculations, design optimization, hazard analysis, and cost-reduction recommendations. We support reverse engineering services. If you have a physical sample without drawings, we can 3D scan, model, and generate production-ready engineering prints. Whether you need a single prototype or thousands of units, we deliver consistent quality with zero MOQ for prototyping stages.

What truly sets Lingyufab apart is our ability to integrate the full spectrum of sheet metal processes, including laser cutting, CNC bending, stamping, welding, powder coating, and assembly, into a seamless manufacturing workflow for machine guards and safety enclosures. Rather than outsourcing individual steps to multiple vendors, we manage everything in-house, ensuring tighter quality control, faster lead times, and consistent communication throughout the entire production cycle. Our structural frames and panel systems are designed for quick assembly—no welding required on site—using bolt-together modular construction. With our in-house fastener manufacturing, we can pre-install hinges, handles, latches, mounting brackets, and anchoring hardware directly onto your guards and enclosures, eliminating external sourcing and reducing installation time on your end. The result is a streamlined, cost-effective solution that provides reliable operator protection, equipment safety, and regulatory compliance in demanding industrial environments.

A machine guard is a physical barrier that protects operators from hazardous machinery, moving parts, flying debris, sparks, and other workplace dangers. A safety enclosure is a fully enclosed structure that completely surrounds a machine or robotic cell, creating a secure isolation zone between personnel and automated equipment.

These safety solutions are essential in industrial environments where operators work near heavy machinery, robots, conveyors, and stamping presses. They prevent injuries, reduce liability, ensure compliance with safety regulations, and maintain a safe, efficient production environment.

Machine guards can be fixed, adjustable, or interlocking. Safety enclosures are typically modular structures made from sheet metal, wire mesh, or aluminum profiles, and can be designed with access doors, safety sensors, and light curtains.

• Industrial Automation: Protecting operators near robotic cells and automated assembly lines.

• Packaging Machinery: Guarding conveyors, sealing equipment, and palletizing systems.

• Material Handling: Creating pedestrian walkways and protecting personnel near conveyor transfer points.

• Manufacturing: Securing stamping presses, CNC machining centers, and welding stations.

• Logistics and Warehousing: Creating storage boundaries and protected work zones.

Lingyufab supports 1-piece prototyping, 100-piece pilot runs, and high-volume mass production with monthly delivery exceeding 5,000 units.

When integrating machine guards and safety enclosures into your sheet metal assembly, consider the following guidelines:

Sheet metal thickness typically ranges from 1.5mm to 4.0mm for panel components. Frame profiles vary based on structural requirements.

Precision is critical for machine guards and safety enclosures to ensure proper fit, alignment, and safety compliance. Lingyufab maintains the following accuracy standards:

These standards are maintained through advanced laser cutting, CNC bending, and welding equipment, combined with rigorous in-process inspection and final quality control checks.

Lingyufab implements a comprehensive quality control system for machine guards and safety enclosures:

Machine guards and safety enclosures can be fabricated into various configurations to suit different protection needs:
