LASER WELDING MOULD REPAIR : Moldmax pulse function laser welding for Mould Repair

Your mould is worn out and flashing ? A core or insert of your tool has cracked? Do you want to join 2 broken pieces of a part into one without damaging the rest of a part ? A cooling system of a tool is leaking?

The Wobble-6PRO+ Series with mould repair function

Extremely Powerful, Reliable and Adaptable

The Wobble-6PRO+ combines flexibility and stability in servicing and repairing small precision components for the aerospace industry as well as large die-casting molds that are, for example, required for the manufacturing of automobile bumpers. The mobile laser system can easily be moved by hand or fixed on a support in a stable position.

The Lasermach Wobble6-PRO+ is an ideal solution for big or recessed work pieces. As a result of portable Welding torch and the mobile laser Source, the welding of large components is virtually independent of geometry and position! In the process, 3D geometries are easily mastered. 

MOLD REPAIR OR REPLACEMENT?

Mold Repair: Laser Welding Delivers Lower Costs and Better Quality

Injection molds and other molds are built to last a certain number of cycles based on their mold class specification. Once a mold reaches its usable life, there can be signs of wear, and replacement components may be necessary. When your mold is approaching the end of its usable life, it’s essential to start looking at long term maintenance costs, proactively ordering back-up components, and possibly, total mold replacement.

Repairing a worn mold is always going to be cheaper than replacing it. The catch is how well that refurbished mold is going to perform in the future. Will it produce parts of equal quality to the original? How long will it last until it needs repair again or has to be scrapped? 

For molds going to the welding repair shop, the quality of the welds and the welding process has everything to do with answering those questions. The most common practice to rebuild worn cavity and core surfaces is with TIG (tungsten inert gas) welding.  However, plastics processors will find that the alternative, pulsed laser welding, delivers a superior result with less damage to the base material, so the mold will produce better quality parts and last significantly longer after the repair.

While TIG (tungsten inert gas) welding may be the go-to for mold welding in many shops, high-power pulsed laser welding is a higher-quality process that can deliver repaired molds that perform like new.

The primary argument for our Wobble-6PRO+ laser welding over conventional TIG or micro TIG welding is that the laser delivers a higher quality end result because it does less collateral damage to adjacent areas of the weld (such as the heat-affected zone). With a conventional welding process, the material in that zone becomes softer and more likely to wear. Microcracks and/or porosity in the weld itself will result in poor surface quality and shortened life of the tool.

Besides of this primary advantage, other benefits of today’s laser welding technology include:

  1. Ability for molds to be repaired multiple times
  2. Quicker repair of molds with much faster machining or bench time
  3. Portable and flexible to reach almost any feature, even in large molds
  4. Less expensive from a total-cost perspective and lasts longer

 

 

Digital control of the welding parameters with one finger on the welding torch

Select Your optimal parameters with a fingertip on your welding torch - Save time by fast parameter setting!

Compared with traditional handheld laser welding machine, the welding advantages are obvious. The laser swing amplitude (range: 0mm-4mm), power, wire feed welding mode etc, can be set through the control system on the torch during the welding process. The width of the weld seam can be customized through the swing amplitude, which solves the defect of traditional hand-held laser welding that requires high weld seams. Greatly improve the welding fault tolerance rate.

On-torch controll and ddisplay of following welding parameters with one finger:

  • Welding power
  • Welding width
  • Welding mode: Continue welding - pulsed welding - laser cutting - laser cleaning
  • Wire feed - wire forward - wire backward
  • Ramping up and ramping down
  • Wire speed forward and backwards

Moreover, safety protection measures have been added, which only emit light to metal! The operation is simple and easy to use, the structure is simple and easy to maintain, the volume is greatly reduced, and the wire can be fed during the welding process, which is suitable for industry and household use.  Change all your welding settings from your workspot.  No need to run to your controller, its all on your fingertips. in the welding torch. 

 

Mold Repair: Laser Welding Delivers Lower Costs and Better Quality

While TIG (tungsten inert gas) welding may be the go-to for mold welding in many shops, high-power pulsed laser welding or fiber laser welding is a higher-quality process that can deliver repaired molds that perform like new.
