Required Info for quoting a Servo Robot
The goal is to make sure the injection molding servo robot fits on your molding machine, then to make sure we apply the right configuration and programming to satisfy your process. We will need this information to complete a quote for your robot. Below we’ve explained why we need each piece of information and why it is helpful.
What size is your molding machine (tons US)?
- This helps us understand how to start sizing the robot. All robots are designed for a specific size range of molding machine.
Will the robot be securing both the runner and parts?
- This helps us understand sequence and end of arm tooling requirements.
Are the parts sub-gated?
- This helps us understand if the parts will still be connected to the runners and if the robot will be required to perform any nipper operations.
- It also helps us understand if the the runner will need to be secured or if you want the runner to fall beneath the press once the mold cycle opens.. (by ejector cycle or other)
This helps us understand a couple things:
- Runner release program sequence
- Will nippers be required if we are dropping runners at separate locations from the parts
- How we design the end of arm tool and if nippers will be on the tool or mounted on the robot or a table
How many cavities in the mold?
- This helps us understand end of arm tool design, potential payload requirements, and robot models (rigidity)
What is the cycle time of the machine?
- This in conjunction with the system sequence requirements helps us understand how much time the robot has to perform the required functions and return to the mold before it opens again.
How many operators are currently working on the machine we are considering a robot on?
- Understanding your current labor rates (loaded wage) times the number of operators times the number of shifts you’re running, helps us to justify implementing automation into your process.
Please provide a set of mold prints
- This helps us understand mold/part design when we design the end of arm tool for extracting parts from the mold face.
Please provide a set of machine prints
- This helps us get accurate dimensions of the machine so we can properly configure the robot model and more importantly, arm strokes.
Critical machine dimensions start with:
- C/L of mold to the top of the platten – this determines main arm stroke and end of arm tool clearance
- C/L of mold to the outside of the safety door of the molding machine
- Distance from top of the platten to the nearest overhead obstruction (lights, crane, ceiling, etc)
- and so on..
Please provide a set of part prints
- This helps us correlate mold prints and overall function of our end of arm tooling during the design phase
