Why Some Injection Molds, Casting Molds Need to Be Repaired by Mold Repair Laser?

  1. Sometimes Precision Molds Have Dimensional Deviations Due to Design Defects, Human Operation Errors and Other Reasons During Processing. It Needs to Be Repaired by Adding a Certain Amount of Weld Stacking through Mold Repair Laser.
  2. In the Injection Molding Process, the Continuous Movement of the Upper and Lower Molds Causes Partial Wear and Tear. Making It Must Be Repaired.
  3. Mold Manufacturers Need to Make Small Partical Modifications to Their Products in the Process of Production Need to Use the Mold Repair Laser. if the Mold is Reopened, the Cost is Large and the Cycle Time is Long. but Through Laser Welding Method, You Can Effectively Control the Production Cost and Improve the Efficiency.

What is the Advantages of Mold Repairing by Mold Laser Welding Machine?

1. Low Oxidation Rate, the Workpiece Will Not Be Discolored.
2. The Weld Joints Can Be Processed, Especially Suitable for Mold Repair with Polishing Requirements.
3. Small Heat Affected Area, Will Not Lead to Precision Mold Deformation.
4. Large Welding Depth, Solid Welding.
5. Full Melting, No Repair Marks Left.
6. No Depression at the Combination of the Raised Part of the Dissolving Pool and the Substrate.
7. No Air Holes or Trachoma After Welding.

The Main Principle of Laser Overlay Repair

Laser Overlay Welding Repair is Through High Power Laser Beam As a Heat Source to Melt the Filling Material to Fill the Defective Parts of the Mold. Because the Laser Energy 10-100% Precise Control and Extremely Small Laser Spot,the Mold Repair Laser for Precision Level Mold Welding Repair is Very Suitable.

Mold Laser Welding Machine Can Effectively Deal with the Welding and Repair Work of Some Tiny Broken Parts of the Mold, Commonly Such As: Various Mold Sand Holes, Chipped Corners, Cracks, Mold Flying Edge, Sealing Edge and Other Tiny Parts of the Repair, to Make Up for the Shortage of Traditional Welding Technology in Repairing the Welded Surface.

Some Core Configurations of the Mold Repair Laser

◆Adopt Advanced Ceramic Light Gathering Cavity, Corrosion Resistance, High-Temperature Resistance, Cavity Life (8-10) Years, and Xenon Lamp Life of More Than 8 Million Times.
◆Adopt an Automatic Shading System, Eliminating the Stimulation of Eyes During the Working Period.
◆10× Microscope Magnification, Cross Cursor Indication, and Automatic Shading with High-Speed Lcd Light Valve. the Protective Gas Output Synchronized with the Laser Ensures That the Solder Joint is Beautiful and the Solder Joint Will Not Be Oxidized and Discolored.
◆The Display Adopts 7-inch LED Screen, Which Can Realize Free Switching Between Chinese and English, Without Worrying About the Language Barrier.
