Once you’ve decided to automate your injection molding process, the first step is assessing how it will integrate into your current operations. Take a close look at your production flow and identify any repetitive or labor-intensive tasks—these are prime opportunities for automation. You’ll also want to examine:
A risk assessment will identify potential hazards for introducing robotics in your specific production environment. Consider things like:
You can mitigate many of the risks involved with robotic Injection Molding by following strict safety standards to avoid injury:
Programming an Injection Molding robot can be a tricky task. Whether you hire a robotics programming expert to help you or opt for a robot with no-code programming software.
Make sure to test the robot at the extremes of its work envelope, known as singularities. At full extension or retraction, a robot can behave unpredictably. Run your robot through various positions at different speeds to ensure smooth operation before production.
When first implementing the robot, focus on straightforward pick-and-place applications. This allows operators to become familiar with the robot's movements and capabilities before advancing to actually removing parts from a working Injection Molding machine. Trying to have the robot interact with the machine before your operators are sufficiently skilled can lead to damage to either machine.
You don’t have to waste valuable time and materials testing your robot in the real world from the get-go. Instead, simulate your robot in a virtual environment which usually comes with most forms of robot programming software. This means you can test if your robot moves properly, follows the pre-defined paths and generally behaves as expected before you let it loose on your shop floor.
While you’ll be familiar with keeping machinery maintained and working, robotics introduces some new items to keep in mind. Here are a few robotics-related maintenance tasks to add to your checklist:
Any robot you buy will come with a lubrication schedule, explaining exactly how and when to apply grease or other lubricants to the joint. Your chosen gripper (end-effector) for your robot will have its own, separate lubrication schedule.
Inspect the robot's sensor lights and adjust the sensory distance if needed. The sensors help the robot detect obstacles and avoid collisions. Small pieces of debris on a lens or guidance system can easily lead to the robot.
Performing routine maintenance and care for your Injection Molding robot will minimize headaches and keep it running productively for years to come. Be sure to factor maintenance costs into your robot budget and choice of model.
Integrating an Injection Molding robot into your manufacturing operations will require restructuring your workflow and retraining your staff. While robots can work independently, they are most effective when collaborating with skilled human workers. Here are some tips for integrating your new automated team member:
Have operators work alongside the robot during initial production runs. This allows them to monitor the robot’s performance, make any necessary adjustments to the programming, and ensure high-quality results. Operators can then gradually hand over control to the robot as they gain confidence in its abilities.
Designate part of your floor space as a human-robot interactive zone. Establish clear pathways in this area and install protective barriers to safely separate workers from the robot. Only authorized, properly trained staff should be allowed access to the interactive zone. If you’re short on space, a Collaborative robot like we mentioned earlier is adept at working safely alongside your team.
Provide robotic safety training for all workers. This includes how to properly activate and deactivate the robot, set up interactive zones, handle robot errors or program changes, and respond in an emergency. All workers should understand how to operate the robot, even if their role doesn’t require interaction with the robot.
Document standard operating procedures (SOPs) for working with the Injection Molding robot. SOPs provide step-by-step instructions for essential tasks like starting a production run, removing finished parts, handling waste materials, and basic troubleshooting. These help ensure consistency and safety compliance.
So there you have it, a practical guide to bringing an Injection Molding robot onto your team. While it may seem daunting, if you methodically work through assessing your current process, address safety and risk, learn some basic programming, and establish a maintenance routine, a polishing robot can be an efficient and cost-effective addition to your operation.
