For years, the cutting of oversized flexible trim components—carpets, headliners, and the like—has been constrained by two stubborn hurdles: delivering consistently smooth, fuzz‑free cross‑sections through multi‑layer stacks, and squeezing more output from a fixed plant footprint. Today, the proven deployment of multi‑station robotic waterjet systems is tackling both head‑on, marking a step‑change in interior parts manufacturing productivity.

 The Challenge: Loading/Unloading Downtime Caps Productivity

 Conventional single‑station robotic waterjet cutting systems have a built‑in inefficiency: while the robot cuts on the worktable, operators must wait until the cycle finishes and the robot returns to its home position before they can enter the safety enclosure for loading and unloading. This alternating wait‑and‑run sequence keeps machine utilization far below its theoretical maximum.

For automotive OEMs and Tier‑1 suppliers producing hundreds of thousands of interior trim sets annually, this stop‑to‑load model has become a critical bottleneck to scaling throughput.

The Breakthrough: Multi‑Station Design Enables Cutting Without Interruption

Leading system integrators have now introduced a fixed‑base, single‑robot dual‑station (or multi‑station) waterjet cutting system that completely redefines the workflow.

     The core innovation is a high‑precision 6‑axis robot (e.g., FANUC or ABB) rigidly mounted on a pedestal, surrounded by two or more fixed worktables. The robot alternates between stations—cutting on Station A while operators safely unload and reload parts on Station B.

This overlapping, parallel‑processing approach eliminates idle waiting time. Real‑world production data shows that dual‑station layouts boost output per unit of time by 80‑100% compared with traditional single‑station systems—essentially delivering nearly two machines' worth of throughput for the capital cost of one robot.

Process Optimization: Tailored for Carpets, Headliners & Soft Trim

This system is specifically engineered for large‑format, flexible interior components:

• Extended reach for oversize parts – With an extended‑arm robot mounted upright, the maximum working radius reaches 3,180 mm, covering a cutting envelope of 2,600 mm × 1,700 mm—enough for SUV and MPV carpets and headliners.
• Vacuum hold‑down for precision – To counteract distortion in flexible materials, each worktable is equipped with custom tooling and a vacuum system. A dense pattern of suction holes secures the material firmly, ensuring zero movement under the high‑pressure jet and delivering clean, burr‑free edges.
• Pure‑water cutting preserves material integrity – Unlike abrasive‑based processes, the system uses pure water at pressures up to 60,000 psi for high‑speed cutting. The cold‑cutting action eliminates heat‑affected zones, preventing melting or deformation, and produces edges so clean that secondary trimming is unnecessary.

Flexible Configurations for Different Production Volumes

The system can be scaled to match your output needs:

• Dual‑station layout – Ideal for mid‑volume production; one robot serves two tables for immediate efficiency gains.

• Three‑ or four‑station layouts – Designed for high‑volume, fast‑cycle operations. The robot rotates among multiple stations, or multiple robots work in synergy (e.g., two robots, three stations) to further reduce individual part cycle times.

Different stations can process the same or different parts simultaneously, offering exceptional flexibility for mixed‑model production. For example, the same system can cut driver‑side, passenger‑side, and rear‑seat carpets in a single sequence, delivering complete sets ready for assembly.

Market Trend: Efficiency Drives Growing Demand

As global automakers raise interior quality standards and push for capacity expansion, demand for multi‑station robotic waterjet cutting systems continues to surge. Recently, multiple equipment suppliers have secured orders from leading interior parts manufacturers for systems dedicated to carpets, headliners, and similar components.

At the heart of these high‑performance systems, KMT ultra‑high‑pressure pumps—along with their original seal assemblies and cylinder components—ensure reliable, sustained operation, delivering consistent cutting power for every precision pass.

Looking Ahead

The shift from "stop‑and‑load" to "cut‑without‑interruption" is redefining productivity benchmarks in automotive interior manufacturing. As fixture designs and process refinements advance, this multi‑station waterjet technology is poised to unlock even greater value across a broader range of flexible material applications.
