Mold repair fiber laser welding machine

Fiber Laser Welding Machine for Mold Repairing

This is a new design CW or QCW fiber laser welding machine for mold repair, QCW lasers have power options of 150W, 200W, and 300W, and CW fiber lasers have power

options of 1500W and 2000W to choose from.

Mould machine welding machine is specially adapted to repair all kinds of moulds, such as plastic injection molds, automotive interior plastic molds, mobile phone bottom plate molds, etc., all kinds of molds of different sizes can be repaired. The mold machine welding machine can repair the mold up to 95 to 99% the same as the original one. Whether it is the appearance of the mold or the actual use, it is impeccable, and it can save a lot of costs for new molds.

Mold laser welder advantage

1. High Precision and Control
Capable of micro-welding even the smallest mold components.
Minimal heat-affected zone (HAZ), which prevents mold deformation or damage.
Accurate positioning for delicate or detailed repairs.
2. Superior Beam Quality
Fiber lasers have a higher beam quality (M² ~1.1), allowing tighter focus and deeper penetration with less power.
Results in cleaner welds and less post-processing.
3. Low Heat Input
Reduces thermal stress and distortion on mold components.
Suitable for temperature-sensitive or high-hardness materials like tool steels (H13, SKD61, etc.).
4. Longer Lifespan and Lower Maintenance
Fiber lasers have a lifespan of 50,000–100,000 hours.
No need for frequent replacement of laser rods or reflectors.
Maintenance is minimal compared to traditional laser systems.
5. High Efficiency and Speed
Fast startup and operation; does not require warm-up time.
Higher welding speed compared to YAG lasers.
Improved production throughput and reduced downtime.
6. Energy Efficiency
Fiber lasers are more energy-efficient (conversion efficiency of ~30–40%) compared to YAG (~3–5%).
Reduced electricity consumption, contributing to long-term cost savings.
7. Compact and Modular Design
Smaller footprint due to the fiber laser's compact design.
Easier integration into workstations or mobile repair setups.

Easy to set up parameter of control system

Easy to learn how to set up parameter of mold laser welder control system. Current. Pulse , Frequency and Spot. The Current. Pulse and Frequency parameters complement each other, but when the Current parameter is adjusted to a high value, the Pulse and Frequency value cannot be increased accordingly. On the contrary, when the other parameters are high, Current needs to be decreased accordingly.

Electric module

Electric module supports forward, backward, left and right movement

Additional circular parameter adjustment screen

In addition to the 7-inch screen control system, we also designed a very small circular screen adjustment. The power, frequency, pulse width, and welding can be adjusted by rotating.
