Build the solution around the production requirement.
Vacuum and mechanical gripping
Vacuum cups suit suitable surfaces and distribute contact, while mechanical grippers can locate on defined features or runners. Many tools combine both methods. Selection follows temperature, surface finish, stiffness, release force, allowable marks and the consequence of a missed grip.
Sensors and grip confirmation
Vacuum switches, part-present sensors, gripper position sensing and mould-clear logic give the control system evidence about each step. The sensing strategy should detect the relevant failure without creating fragile complexity.
Multi-cavity and dual-purpose tooling
A single frame can retain multiple cavities, keep families separated, pick a sprue independently or carry fresh inserts for the next cycle. Tool weight and moment are included in robot payload calculations, together with valves, manifolds, cables and fittings.
Quick change and maintainability
Manual or automatic quick-change interfaces reduce downtime when products change. Accessible wear parts, labelled pneumatics, protected cables and documented set-up points make the tooling easier to maintain in real production.
Specification checklist
| Contact method | Vacuum cups, mechanical grippers, sprue grippers or a hybrid |
|---|---|
| Design inputs | Part CAD/sample, mould access, release points, temperature and cycle forces |
| Confirmation | Vacuum level, gripper position, part present, insert present and tool identity |
| Production needs | Changeover, cleaning, spare wear parts, cable protection and maintenance access |
Frequently asked questions
What does EOAT mean?
EOAT means end-of-arm tooling: the gripper, frame, sensors and services attached to the robot wrist.
Does EOAT weight count in robot payload?
Yes. The complete moving load includes tooling, components, sprue, valves, sensors and cables, with suitable allowance for dynamics.
Can one EOAT handle several products?
Sometimes. Adjustable nests, shared grip features or quick-change tooling can support variants, but the safest and fastest approach depends on the products.
