NS-M Series Models
Model | Head type | Adjustment | Maximum stated power | Distinctive role |
NS20M | Standard mold/die welding head | Manual focus/beam adjustment | Up to 3000W, subject to complete optical and cooling configuration | Standard repair head with microscope-ready arrangement |
NS20M-D | Compact short mold/die head | Manual focus/beam adjustment | Up to 3000W, subject to complete optical and cooling configuration | Short housing for limited installation space or tighter access |
NS20M-S | Dual-axis oscillating repair head | Dual-axis beam oscillation | Up to 3000W, subject to complete optical and cooling configuration | Wider, controllable weld patterns for suitable repair and buildup tasks |
Maximum head rating does not mean every laser source, connector, optic, cable, or cooling package is automatically compatible. The optical and control requirements for pulsed YAG laser welding differ from those for QCW laser technology for mold repair, so the complete optical path, thermal design, and interface must be reviewed before selection.
Select the Head by Integration Requirement
NS20M: Standard repair head
Use the NS20M when the machine has adequate installation space and requires manual spot adjustment with an observation interface for precision mold repair.
NS20M-D: Compact short version
Use the NS20M-D when head length or working clearance is limited. Confirm that the compact housing still provides the required optical path, mounting, observation, and service access.
NS20M-S: Dual-axis oscillating version
Use the NS20M-S when a controlled oscillating pattern can help create a wider bead or cover a larger prepared area. Wobble range, control compatibility, spot behavior, and repair quality must be validated with the complete system.
Typical Repair Applications
- Mold and die repair stations
- Injection-mold edge, cavity, and local buildup systems
- Die-casting and stamping-tool repair equipment
- Custom cantilever, jib-arm, articulated-arm, or fixed repair platforms
- Replacement or upgrade projects where the existing optical and mechanical interfaces can be verified
This page does not select a complete mold welder. For full systems, compare complete mold repair laser welding machines by working reach, source type, observation method, motion control, and the location of the repair.
Compatibility Information Required
Send the following before a head is quoted:
- Laser-source brand, model, wavelength, and maximum output
- Operating mode: QCW, CW, pulsed YAG, or another source type
- Fiber connector or optical input interface
- Collimation and focusing requirements
- Existing mounting drawing and available installation space
- Cooling method, flow, and connection requirements
- Control signals and oscillation-controller requirements
- Microscope, LED, camera, or other observation interface
- Required spot size, working distance, and wobble pattern
- Target material, repair geometry, and filler-wire process
What Is Included?
The exact package must be stated on the quotation. Depending on the model and project, it may include the head body and selected optical, observation, or control accessories. Do not assume that the laser source, chiller, motion axes, controller, safety enclosure, cable set, or installation service is included unless it is listed.

Frequently Asked Questions
Is the NS20M a complete mold repair laser welding machine?
No. It is a welding-head component. A complete machine requires the laser source, cooling, controls, motion platform, electrical system, guarding, and other integration work.
Can the head connect to any 3000W laser source?
No universal compatibility should be assumed. Source mode, wavelength, connector, optics, cooling, control signals, and the complete power path must be verified.
What is the difference between NS20M and NS20M-D?
The NS20M is the standard configuration. The NS20M-D uses a shorter housing for installations with limited space or access.
When should I use NS20M-S?
Use it when dual-axis oscillation is required for a controlled wider bead or repair pattern and the complete source, control, optics, and cooling package is compatible.
Can Riselaser review an existing machine for replacement-head compatibility?
Yes. Send the source nameplate, current-head model, connector photos, optical and mounting drawings, cooling details, control information, and the intended repair process.
