For this example: Let's assume a plastic injection molding process.

Before building an EOAT, these robot capabilities must be determined.

1. Payload: ______
2. Mounting plate pattern: ________
3. Available movement pattern (e.g. 3-axis, articulating): __________
4. Range of motion: ______________
5. Speed and sequence of operation: _____________
6. Air, vacuum and electric circuits available: _____________

Check Molding Conditions

1. Mold drawings
2. Daylight available
3. Distance between tie bars
4. Location and stroke of ejector pins
5. Cycle time
6. Overhead/side obstructions
7. Temperature of ejected part

After looking at mold conditions answer these questions:

1. How many cavities?
2. Will the part remove easily?
3. Can vacuum cups remove the part or will mechanical grippers be necessary?
4. What type surface is on the parts?

Questions to ask about the End-of-Arm Tool you want:

1. Will the tool be used on one specific robot and press or many?
2. Does the tool need to be switched quickly and stored?
3. Will the tool be adjustable and reusable?
4. Is individual part detection needed?
5. Do the parts need to be cut, trimmed, or separated?
6. Can the parts be packaged straight from the press?
7. Do inserts or labels need to be placed in the mold for the next part?
