MECCOweld Fiber Laser System
Models: 200W, 300W
Weld Your Plastic Parts with Fiber Lasers
Stay competitive by using the most advanced technology: fiber lasers that provide superior results. As a leader in cutting-edge laser technologies, MECCO has been using our extensive applications experience to expertly laser weld millions of parts in various industries. Over the past five years, we've developed laser welding systems that have proven to be cleaner, faster, and more cost effective. Shear testing results have shown laser weld strengths that rival even that of a solid piece of plastic.

Features of Fiber Laser Plastic Welding Systems
- Hermetic seals possible
- Fast process
- No contact with heated tools
- No vibration
- Precise placement
- No surface damage
- Complex 3D shapes possible
- Little or no flash
- Ability to join dissimilar materials
- Good quality control
- Less material needed than that for friction welding methods
Potential Materials
Any thermoplastic is a candidate for laser welding to itself.
For Transmission Welding:
- Must have one transparent part and one opaque part (using darkening additives or natural absorption from its structure and color)
- Example: Carbon black
- Melting temperatures should have a 50°C overlap range
- Allows for melting phase (between solid and decomposition phases) to be compatible
Making a Stronger Weld
CASE STUDY: Fiber Laser Test Results
A manufacturer redesigned one of their spin welded applications to be laser welded. With an internal requirement of 400N of shear force, the change would only be possible if laser welds could meet that goal. Testing MECCO's laser welds, they found:
- Laser welded pieces break at 1,200N (compared to breaking at 800N for spin friction welds)
- Achieved weld strengths of 5 MPa or more of shear pressure
- At that pressure, the plastic often fails before the weld does
