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.
