Compact 16kg Payload 967mm Reach Collaborative Robot Arm for Molding Unloading

Compact 16kg Payload 967mm Reach Collaborative Robot Arm for Molding Unloading

This compact 16kg payload 967mm reach collaborative robot arm delivers heavy payload capability in a body that still fits inside a guarded machine cell. A 16 kg rated payload, 967.5 mm working radius, 38.9 kg body and 0.03 mm repeatability give a payload to weight ratio of about one to two and a half, so a sprue picker, a heavy gripper or a two-part fixture can be carried without resizing the pedestal.

Injection moulding unloading is the reference application: the arm reaches into the open mould, grips the runner or the part, withdraws inside the cooling interval and places onto a conveyor, with 3.0 m/s tool speed and 267 degrees per second on the third joint keeping the move short. The same envelope suits die casting take-out, press unloading and dense machine islands where several arms work close together.

Because the collaborative robot arm is certified to ISO 13849 PL d Cat. 3 and can be mounted at any angle, it is commonly hung from a machine frame above the mould area, leaving the floor clear. Approvals include CE, NRTL, KCs, CR, SEMI S2 and RoHS, the arm carries an ISO Class 4 cleanroom rating, and the controller exposes 16 digital inputs and 16 digital outputs plus ModBus, Profinet and EtherNet/IP options for the machine handshake.

Key Specifications

Advantages

• 16kg payload in a compact body: about a one to two and a half payload to weight ratio keeps the mounting structure light.
• 967.5mm reach: enters an open mould, a press or a die casting cavity from a frame mount without a slide.
• 0.03mm repeatability: repeatable insert placement and part extraction protect expensive tooling.
• 267 degrees per second on joint 3: quick wrist rotation shortens the extraction move inside the cooling window.
• Overhead mounting: any-angle base clears floor space around the machine and keeps the operator aisle open.
• Heavy tool support: 3 A at the flange carries large vacuum frames, sprue grippers and two-part end effectors.
• Certified collaboration: ISO 13849 PL d Cat. 3 allows guarded-zone layouts without full fencing.
• Same controller family: identical cabinet, teach pendant and SDK as the rest of the i-Series fleet.

Applications

• Injection moulding machine unloading: runner and part extraction
• Insert loading into moulds before the clamp closes
• Die casting take-out and quenching transfer
• Press and stamping line unloading
• Machining cell tending where a heavy gripper is needed
• Packing of moulded components into returnable totes
• Sprue separation and scrap drop into granulators
• Dense multi-machine islands with overhead mounted arms

FAQ

Q: How does a 16kg payload arm stay compact enough for a moulding cell?

A: The arm body weighs 38.9 kg and sits on a 218 mm base circle, so it mounts on a machine frame above the mould rather than beside it. The compact envelope keeps the arm outside the clamp area while still reaching a 967.5 mm radius into the cavity.

Q: How fast is a mould unloading cycle?

A: Tool speed is 3.0 m/s and the third joint turns at 267 degrees per second, so a typical extract and place move completes in two to three seconds. The limiting factor is usually the mould opening stroke rather than the arm.

Q: Can the arm place inserts before the mould closes?

A: Yes. Insert placement repeatability is 0.03 mm at the flange, and the machine handshake via digital I/O or ModBus confirms the arm has cleared the parting line before the clamp is enabled.

Q: Is overhead mounting safe?

A: Yes. The base is designed for any mounting angle and the controller applies gravity compensation for inverted orientation. A certified drop-safe bracket and a risk assessment are part of a standard overhead installation.

Q: Which end effectors suit moulding work?

A: Sprue grippers, magnetic and vacuum part grippers, two-jaw parallel grippers and combined part plus runner tools all run from the 4 configurable digital outputs, 2 analogue inputs and 24 V 3 A supply at the flange.

Q: What are the commercial terms?

A: Minimum order one piece, stock in 3 working days and configured arms in 15 to 25 days. FOB or CIF terms, calibration report included, 12 month warranty on parts with remote technical support.

Q: How do I request a quotation?

A: Send your part weight, cycle requirement, fixture layout and plant voltage. Our engineers confirm the payload and centre of gravity margin, propose the end effector and mounting arrangement, and return a price, lead time and integration drawing for this 16 kg collaborative robot arm.
