As injection molding automation continues to advance, robotic arms have largely replaced traditional manual loading and unloading, becoming an essential part of modern injection molding production lines. These robots can synchronize with the injection molding cycle and operate at high speed, delivering significant gains in both production capacity and efficiency.

However, behind this high productivity are significant safety risks. Injection molding robots operate at high speeds and exert considerable gripping force, creating the potential for serious workplace accidents such as crushing and pinching injuries. While some incidents may only disrupt production, others can pose a serious threat to personnel safety.

Safety is never a minor issue—it is always better to prevent accidents before they happen. So, what professional safety protection products should be used to address the key hazards associated with injection molding robots? And how can manufacturers achieve both safety and production efficiency? Let’s take a closer look at three practical and reliable protection solutions.

1. Moncee Yinwei MZS-01 3D Photoelectric Sensor: 3D Protection Without Disrupting Production

To address the frequent risk of injuries caused by injection molding robots, various safety protection products have emerged on the market. Among the more mature, reliable, and adaptable solutions is the Moncee Yin Wei MZS-01 3D Photoelectric Sensor.

Unlike traditional safety protection devices that are limited to single-point or single-plane protection, the MZS-01 uses three-dimensional protection technology, allowing the protection zone to be freely configured according to the machine layout, working space, operator movement paths, and other site-specific conditions.

The Moncee Yin Wei MZS-01 uses specialized safety control logic designed specifically for injection molding applications. It controls the safety signal only during the hazardous downward movement of the robot arm outside the mold, achieving a protection concept of “production inside the mold, protection outside the mold.”

When the robot arm is picking up or placing products inside the mold, personnel entering the protection zone will not trigger a machine stop, ensuring that normal production cycles remain uninterrupted.

However, when the robot arm moves outside the mold and begins its downward movement, if personnel are still detected within the protected area, the system immediately outputs a safety signal and commands the robot arm to stop descending.

This effectively prevents crushing and pinching accidents at their source while maintaining production efficiency and protecting operator safety.

2. Safety Mat: A Cost-Effective and Durable Solution for Complex Workshop Conditions

In addition to 3D photoelectric sensors, Safety Mats are another widely used and cost-effective solution for protecting injection molding machine robots.

A Safety Mat is a pressure-sensitive safety sensor featuring a dual-layer membrane switch structure. When pressure is applied by stepping on the mat, the switch closes and triggers a safety signal. When no pressure is applied, the circuit automatically opens.

It offers excellent durability, slip and oil resistance, impact resistance, and resistance to repeated foot traffic, making it suitable for the demanding conditions commonly found in injection molding workshops, including oil contamination, dust, and frequent stepping.

The Safety Mat also offers a long service life and low maintenance costs.

Its size, shape, and thickness can be highly customized, allowing it to be flexibly installed around the machine and operator work areas according to the available space. It is easy to install and operate and can be adapted to most injection molding machines and workshop layouts.

In terms of safety control, the Safety Mat is specifically used to control the downward movement signal of the injection molding robot, providing a reliable safety logic similar to that of the 3D photoelectric sensor.

When the robot arm is picking up products inside the mold, personnel standing on the mat will not interfere with normal machine operation.

When the robot arm moves outside the mold, however, detecting a person stepping on the mat immediately stops the downward movement of the equipment, helping prevent crushing and pinching injuries while maintaining production efficiency.

3. Moncee Minyou MVS-HDS Vision Camera: AI-Powered Recognition to Distinguish People from Objects

For modern smart injection molding workshops seeking intelligent and high-precision safety protection, the Moncee Min You MVS-HDS Vision Camera is an advanced safety solution.

Powered by advanced AI algorithms, the product features human-shape recognition and can be configured to detect people while ignoring objects, effectively reducing false triggers caused by materials, tools, and other objects while maintaining both safety and production continuity.

The protection zone can be flexibly configured according to the machine layout and working space, making the system suitable for a variety of injection molding applications.

At the core of the vision sensor is AI human detection technology, supported by a proprietary intelligent detection algorithm. It can capture real-time images of the working area, perform dynamic analysis and intelligent comparison, and deliver accurate identification with rapid response.

When the system detects a person entering a hazardous working area outside the mold, it immediately outputs a safety trigger signal and rapidly communicates with the injection molding machine and robot control systems to initiate emergency deceleration or shutdown.

This helps prevent crushing and pinching accidents at the source, providing a smarter and more reliable safety solution for automated injection molding production lines.
