Product Introduction

Herolaser mould repairing laser welding machine series are specialized for the mold industry works, this model dedicated to replacing the traditional argon welder for repairing precision molds. All the key components of this machine are imported. The software operating interface use large LCD screen and display multi-languages interface, it is simple and easy to use for operator. Multiple presetting operating mode, also can program by users, permanent memory function, applicable to a variety of materials.

Equipped with special microscope observation system, magnification 10x; There is a high-speed electronic filter protection device to protect the operator's eyes from laser damage, alleviate the operator's eye fatigue and improve the working efficiency

The synchronous argon protection system with internal microcomputer control can prevent the weld from being oxidized and make the welding more firm and beautiful; Argon can be saved to the greatest extent by adopting synchronous control with laser emission

Core Features

1. Heat affected zone is small, little deformation for precision molds.
2. Welding depth is large, welding firmly. Sufficient fusion, no repairing traces. No dimple phenomena at combining position of projection parts and bulge part of molten pool soluble material.
3. Low oxidation rate, the color of the processing parts is intact.
4. No stomata or sand hole disappeared after welding.
5. The welding parts can be processed, especially suitable for polishing requirements of the mold repair.
6. The processing parts can reach to 50 to 60 Rockwell hardness.

No deformation of welding die

The heat affected area is small, which will not lead to the deformation of the precision die, and there is no depression at the joint between the convex part of the molten material in the molten pool and the matrix.

● The oxidation rate is low and the workpiece will not change color after welding
● The heating area is small, and the machined parts will not deform
● There will be no pores or trachoma after welding
● After welding, it can be etched without affecting the effect
