SZGH-T2950-3C-6 Six-Axis Articulated Robot — Longest Reach in the T-Series

The SZGH-T2950-3C-6 is a six-axis articulated industrial robot with the longest working reach in the T-series at 2,950 mm, purpose-built to meet the cycle time and process demands of large injection moulding machines — including deep mould-cavity access for part extraction on 1,000–2,000+ tonne presses, direct transfer to trim stations, and large plastic part handling — where robots with shorter reach cannot safely enter the mould opening.

Core Advantages

T-Series Reach Record — 2,950 mm (Near 3-Metre Working Radius)

At 2,950 mm, the T2950-3C-6 offers nearly 3 metres of working radius — the largest of any SZGH T-series robot. This extended reach is the single most important parameter when servicing large injection moulding presses: the robot must extend past the tie bars, into the mould-open space, and reach the deepest cavity ejection point in a single motion without the end-of-arm tool contacting machine structure.

Purpose-Designed for Large Injection Moulding Machine Cycles

The T2950-3C-6's motion profile and reach configuration are engineered specifically to match the cycle timing and physical access constraints of large injection moulding machines (1,000–2,000+ tonne). Part extraction, degating, and transfer to downstream trim stations can be executed within the mould's open time, enabling the robot to pace-match the press without adding idle time to the moulding cycle.

30 kg Payload Covers the Full Range of Large Injection Moulded Parts

Automotive interior parts moulded on large-tonnage presses — dashboard structures, door panels, bumper fascias, instrument carrier frames — typically weigh 8–25 kg. The T2950-3C-6's 30 kg payload provides a comfortable working margin across this entire part weight range, including when vacuum-cup end-of-arm tooling (typically 4–8 kg) is added.

Axis 1 Optimised at ±100° for Single-Direction Machine Service

Unlike the wider ±175° Axis 1 range on models designed for multi-position cell layouts, the T2950-3C-6 uses a focused ±100° Axis 1 sweep. For large injection moulding service — where the robot operates from a fixed frontal position relative to the press and transfers parts to a single outfeed conveyor or trim press — this concentrated rotation reduces inertia and allows faster net axis motion within the relevant working arc, contributing to shorter extraction-to-transfer cycle times.

Ceiling and Bracket Mounting Eliminates Floor Space Competition with Press Auxiliaries

Large injection moulding machines are surrounded by barrel dryers, material loaders, water temperature controllers, and mould cooling circuits. The T2950-3C-6 supports ceiling and bracket mounting, allowing the robot to be positioned above the machine access zone rather than competing for floor space with process auxiliaries — an important practical advantage on production floors with constrained layouts.

Application Scenarios

T-Series Comparison: 30 kg Long-Reach Models

Choose T2950-3C-6 for press service requiring >2,300 mm reach. The focused Axis 1 range (±100°) is a feature, not a limitation — it optimises cycle time for single-direction press-front operation.

Customer Case Study

By Fannie Chen, CEO, Shenzhen Guanhong Automation Co., Ltd. (SZGH) | May 2026

One project that genuinely tested the limits of our T-series reach capability came from an automotive interior plastics plant in Thailand. They were moulding instrument panel structures on a 2,000-tonne press — large parts, approximately 18 kg each, and the mould cavity was deep enough that any extraction robot needed a working reach of at least 2,500 mm just to get the gripper to the ejector pin level safely.

They had evaluated two competitor robots before contacting us. Both offered around 2,200 mm reach, and during dry-run trials neither could reliably enter the mould cavity without the robot's elbow joint risking contact with the tie bars on re-entry. Their automation engineer described it to me as "like trying to reach into a box with your arm that's slightly too short — you can get in, but you can't guarantee you won't clip the edge on the way out."

The T2950-3C-6's 2,950 mm reach resolved the clearance problem entirely. We ran a digital reach simulation against their press drawings before any hardware was committed, confirming that the robot's elbow trajectory maintained a safe 120 mm clearance from the tie bars at all points in the extraction path. After physical installation, the robot demonstrated a complete extraction-and-transfer cycle — mould-entry to part deposited at the trim station — in 6 seconds flat, perfectly matching the press open time without any added wait.

Eighteen months after installation, the customer confirmed zero extraction-related mould damage incidents, compared to four per year under their previous manual extraction process. That data point means more to me than cycle time alone.

Control System & Integration Notes

The T2950-3C-6 is designed for use with the SZGH-CNC series robot controller, which provides:

• 6-axis coordinated motion with optimised trajectory interpolation for deep-reach extraction paths

• Press signal interface (mould-open / mould-close confirmation) via dry contact or 24V I/O

• EtherCAT / Modbus TCP / Profibus fieldbus for integration with injection moulding machine controllers (e.g. Engel, Haitian, KraussMaffei, Yizumi)

• Teach pendant with colour touchscreen, one-touch program selection, and cycle counter

• Collision detection with configurable axis-level soft limits to protect mould surface during cavity entry

• Part presence verification via vacuum pressure monitoring or optical sensor integration

• Remote diagnostics support via LAN

End-of-Arm Tooling: The ISO 9283-compliant wrist flange supports vacuum cup assemblies, mechanical gripper frames, and combined vacuum/pin tooling. For large plastic panel extraction, SZGH recommends lightweight aluminium EOAT frames with distributed vacuum cups to maintain part geometry during high-speed transfer. Maximum EOAT weight including vacuum generator: 8 kg recommended to maximise usable payload margin.

Press Interface: SZGH provides a standard press I/O wiring kit for signal handshake with the injection moulding machine safety circuit, including mould-open permission, robot-clear confirmation, and emergency stop relay interconnect.

Frequently Asked Questions

Q1. What is the maximum reach of the SZGH-T2950-3C-6?

The T2950-3C-6 reaches 2,950 mm — the longest working radius in the SZGH T-series. This is specifically designed to provide safe, clearance-compliant access into large injection mould cavities on presses from 1,000 to 2,000+ tonnes where shorter-reach robots cannot reach the ejector plane without risking contact with machine structure.

Q2. What size injection moulding machines is the T2950-3C-6 designed for?

The T2950-3C-6 is primarily targeted at large-tonnage injection moulding machines in the 1,000–2,000+ tonne range, where the distance from the robot base mounting position to the deepest part of the mould cavity exceeds 2,300 mm. For machines below 1,000 tonnes with shorter platen distances, the T2300-3C-6 (2,300 mm reach) may be sufficient.

Q3. Why does the T2950-3C-6 have a ±100° Axis 1 range instead of ±175°?

The ±100° Axis 1 range is a deliberate design choice for large injection moulding applications, not a limitation. Press-service robots operate in a single frontal direction — extracting from the mould and depositing to a conveyor or trim station on the same side. Concentrating the Axis 1 sweep to ±100° reduces rotational inertia and allows the robot to achieve faster effective cycle times within the relevant working arc. For applications requiring ±175° Axis 1 swing, the T2300-3C-6 is available.

Q4. How much does a typical injection moulded automotive part weigh relative to the 30 kg payload?

Automotive interior parts moulded on large-tonnage presses typically weigh 8–25 kg. Dashboard structures, door panels, and bumper fascias fall within this range. Adding a typical vacuum EOAT frame (4–8 kg), the total pick weight remains well within the 30 kg rated capacity, providing a genuine working margin for dynamic load peaks during high-speed transfer.

Q5. Can the T2950-3C-6 interface directly with injection moulding machine controllers?

Yes. The SZGH-CNC controller provides a press signal interface via dry contact or 24V I/O, supporting mould-open/mould-close handshaking and robot-clear confirmation. SZGH also provides a standard wiring kit for interconnecting the robot's emergency stop relay with the moulding machine's safety circuit.

Q6. What mounting options are available and which is most common for this application?

The T2950-3C-6 supports ground, bracket, and ceiling mounting. For large injection moulding machines, overhead (ceiling) mounting is the most common choice because it positions the robot above the cluttered floor space around the press — occupied by dryers, temperature controllers, and water circuits — without competing for floor area.

Q7. How does the T2950-3C-6 compare to the T2300-3C-6 for injection moulding?

Both are 30 kg, 6-axis robots. The T2950-3C-6 adds 650 mm of reach (2,950 mm vs. 2,300 mm) and narrows the Axis 1 sweep (±100° vs. ±175°). For presses where the cavity-to-robot-base distance requires more than 2,300 mm, the T2950-3C-6 is the correct choice. For smaller presses or applications requiring wide lateral swing, the T2300-3C-6 is preferred.

Q8. Does SZGH offer reach simulation services before order confirmation?

Yes. Given that reach adequacy is critical for large-press applications, SZGH provides digital reach simulation using customer-supplied press drawings or known machine specifications. The simulation confirms clearance compliance for the complete extraction path before any hardware commitment. Contact export02@szghtech.com to initiate this process.
