Why Choose the P1950-B-6

1,950 mm Reach — Full-Sweep Coverage of Automotive-Scale Workpieces

At 1,950 mm, the P1950-B-6 adds 450 mm of working radius over the P1500-B-6. An automotive instrument panel measuring 1,500 mm × 600 mm can be sprayed from one side to the other in a single continuous pass — no robot repositioning, no joint seams in the coating path, no film-thickness discontinuity at the midpoint. For large appliance panels, engineering enclosures, and automotive door liners, this is the critical threshold.

Dust-proof & Waterproof Sealed Structure — P-Series Exclusive

Paint booths are not clean rooms. They are dense with atomised solvent particles, metallic pigment dust, and humidity. The P1950-B-6 carries P-series exclusive dust-proof and waterproof sealing across every joint, cable entry, and controller interface. In verified customer installations, this structure has sustained 18+ months of continuous paint-booth operation with zero seal failures — a reliability benchmark that general-purpose robots without this sealing cannot match.

Axis 6 at 360°/sec — Uniform Film Build Across Complex Large Surfaces

Larger workpieces with compound curves — automotive fascias, bumpers, instrument panels — demand rapid wrist rotation as the arm traverses the full 1,950 mm sweep at painting speed. At 360°/sec, Axis 6 maintains a perpendicular gun angle to the workpiece surface throughout. The practical result: film-thickness deviation is held within specifications on every pass, regardless of surface curvature changes, producing the visual uniformity that automotive OEM quality gates require.

Axis 4 Range ±200° — Wider Wrist for Deep-Cavity and Undercut Surfaces

The ±200° Axis 4 range (versus ±150° on general-purpose T-series robots) enables the wrist to reach deep recesses, undercuts, and A-pillar transitions on automotive interiors without a full arm reorientation. For injection-moulded parts with lip features or stepped surfaces, this additional range eliminates the need for secondary fixture positioning.

Rotary Table Painting for Injection-Moulded Parts — Zero Dead Zones

When combined with a rotary positioning table, the P1950-B-6 performs continuous rotary spray painting for injection-moulded parts: the table rotates the workpiece while the robot maintains the optimum spray standoff and angle. This is the standard approach for instrument panels requiring dual-colour (e.g., matte black base + metallic silver accent) sequential application — each colour cycle completes without manual part handling.

Application Scenarios

P1950-B-6 vs P1500-B-6 — Which Model Is Right for You?

Selection Guide:

• Choose P1950-B-6 when workpiece dimensions exceed 600 mm (automotive panels, large injection-moulded housings, appliance doors), or when the application involves rotary table painting of large 3D parts.

• Choose P1500-B-6 when workpieces fit within a 600 mm envelope, your line uses a conveyor with hanging-line tracking, and the tighter ±0.05 mm repeatability is required.

Customer Case Study

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

In early 2024, I visited a plastics supplier in Thailand — a Tier-2 automotive parts manufacturer supplying to a Japanese OEM assembly plant. Their main products were instrument panels and centre console panels. The largest part measured 1,500 mm × 600 mm. Each piece required a two-tone finish: matte black base coat, followed by metallic silver accent on the upper register. Beautiful specification. Extremely difficult to execute manually at the consistency level an OEM requires.

The problem was not the painters. They were experienced. The problem was human geometry: maintaining a perfectly steady gun-to-surface standoff across a 1,500 mm sweep, twice per part (once per colour), at production speed, for eight hours, is simply beyond reliable human motor consistency. The OEM's exterior QC team was rejecting approximately 9% of shipments — orange peel, overspray at the colour boundary, and film-thickness variation at the edges of the metallic silver zone.

We installed one P1950-B-6 paired with a rotary positioning table and an automatic colour-change valve. The 1,950 mm reach covers the instrument panel from left edge to right edge in one uninterrupted sweep — no seam, no robot repositioning, no film discontinuity at a midpoint join. The matte black base coat runs first; after the programmed colour-change sequence (automatic solvent flush + refill), the metallic silver pass follows. Total cycle time per part: 1 minute 45 seconds, down from 4 minutes 20 seconds by hand.

The dust-proof and waterproof sealing is not a box-tick for this application — it is load-bearing. The spray booth in that factory runs two shifts, six days a week, with lacquer solvents and metallic pigment particulate in the air throughout. The P1950-B-6 has been running in that environment for over 18 months without a single seal-related incident.

OEM rejection rate: from 9% to 0.3%. The Thai factory's quality manager told me in a follow-up call that they had just received a new model nomination from the OEM for a third panel variant. The robot was not just solving a problem — it was opening the next contract.

Control System & Integration

SZGH Dedicated Painting Controller

The P1950-B-6 ships with the SZGH-CNC painting robot controller, configured for P-series painting robots and tuned for large-sweep continuous-path applications. Key features include:

• Large-workpiece path optimisation: trajectory computation for long linear and arc paths that maintain consistent gun standoff across the full 1,950 mm sweep

• Colour-change valve I/O: dedicated digital outputs for controlling automatic solvent-flush and sequential colour-change valve operations (dual-colour and multi-colour sequences)

• Paint flow / atomising air control: analogue output for proportional gun triggering with adaptive pressure compensation for large standoff distances

• Teach pendant: 10-inch colour touchscreen with painting-specific trajectory templates (linear sweep, arc, zigzag, spiral, rotary-coordinated)

• Offline programming: CAD-based path import for complex 3D surfaces — enables new-part programming without stopping production

Positioner (Repositioner) Integration

The P1950-B-6 is designed for coordinated motion with SZGH positioners, unlocking full 360° no-dead-zone coverage of large 3D workpieces:

In 9-axis coordinated mode, the three positioner axes and six robot axes are interpolated together by the controller — the spray gun maintains a constant programmed standoff distance from the workpiece surface throughout every rotation and tilt movement. This is the configuration required for complete, no-shadow coverage of deeply formed automotive parts.

Frequently Asked Questions

Q1: What is the maximum workpiece size the P1950-B-6 can paint in a single setup?

With a 1,950 mm working radius and ±175° waist rotation, the P1950-B-6 can cover a workpiece up to approximately 1,500 mm in its longest linear dimension in a single uninterrupted sweep. When combined with a 3-axis positioner in 9-axis coordinated mode, even larger and more complex workpieces — motorcycle frames, automotive door assemblies — can be fully painted without repositioning.

Q2: What does "dust-proof and waterproof" mean in practice for a paint booth robot?

The P1950-B-6 carries P-series exclusive sealing across all joint enclosures, motor housings, encoder covers, and cable entry points. "Dust-proof" means paint pigment and metallic particulate cannot migrate into the joint mechanisms or motor windings. "Waterproof" means solvent mist and humidity cannot penetrate. The practical outcome: sealing integrity sustained over 18+ months of continuous two-shift paint booth operation in verified customer installations, with no seal failures recorded.

Q3: Can the P1950-B-6 handle dual-colour (two-tone) painting automatically?

Yes. With an automatic colour-change valve manifold integrated via the controller's digital I/O, the P1950-B-6 executes sequential dual-colour (or multi-colour) programs within a single robot cycle: first-colour path → automatic flush → second-colour path. No manual intervention between colours. This is the standard configuration for automotive instrument panels and consumer electronics housings requiring matte/gloss or base/metallic two-tone finishes.

Q4: How does the P1950-B-6 compare to a human painter on a large workpiece like a car dashboard?

A skilled human painter maintaining consistent gun-to-surface standoff across a 1,500 mm sweep, twice per part (two colours), for a full shift, will inevitably produce film-thickness variation — particularly at the extremes of reach. The P1950-B-6 holds programmed standoff and travel speed throughout each pass. In the Thailand automotive case described above, OEM rejection rates dropped from 9% to 0.3% after installation. Paint consumption per part also decreases because the robot does not over-spray to compensate for positional uncertainty.

Q5: What is the difference between the P1950-B-6 and the T1850-D-6 general-purpose robot?

The T1850-D-6 is a general-purpose robot for welding, handling, and assembly. The P1950-B-6 differs in four ways critical to painting:

(1) Dust-proof and waterproof sealing — the T-series does not carry this protection level for paint-booth environments;

(2) Axis 6 at 360°/sec versus 222°/sec on the T-series;

(3) Axis 4 range ±200° versus ±150° on the T-series;

(4) The P-series controller is pre-configured with painting-specific trajectory templates, colour-change valve I/O, and gun trigger control.

Q6: Is ceiling mounting available for the P1950-B-6?

Yes. The P1950-B-6 supports ground, bracket (wall/frame), and ceiling mounting. Ceiling mounting is used in large-panel painting lines where the workpiece is transported on a floor-level conveyor beneath the robot. The controller's gravity compensation parameters are reconfigured automatically for the selected mounting orientation, preserving positioning accuracy and axis torque limits regardless of mount angle.

Q7: How long does commissioning take for a new P1950-B-6 installation?

A standard ground-mounted P1950-B-6 installation — robot, positioner, colour-change valve, safety fencing — typically reaches first-part production within 5–10 working days from delivery, assuming the paint booth and compressed-air infrastructure are ready. SZGH engineers provide remote commissioning support via video call and WhatsApp, and on-site commissioning is available through global service partners in the USA, Turkey, Romania, Russia, Egypt, Thailand, and Mexico.

Q8: What ongoing maintenance does the P1950-B-6 require in a high-production paint environment?

The primary maintenance schedule includes: joint grease replenishment (per manufacturer interval, typically every 2,000–3,000 operating hours), periodic seal inspection (at 6-month intervals for high-intensity two-shift operations), and teach-program backup (recommended monthly or after any significant program revision). The spray gun, supply lines, and colour-change valve are maintained per the gun manufacturer's schedule, independently of the robot maintenance cycle. SZGH provides a maintenance checklist and consumables supply through the global service partner network.
