About Clearweld – Plastics Laser Welding Technology

Clearweld is a patented plastics laser welding technology that offers product designers and engineers unprecedented design and color flexibility, product performance, and cost-effective manufacturing solutions.

Clearweld's specialized and precise joining method for colored or clear plastics offers superior engineering advantages compared to today's adhesive and solvent bonding, and ultrasonic, vibration and hot-plate welding methods. No particulates, no vibration or surface marring, strong, hermetic welds, color flexibility, complex geometry capabilities, and high speed welds are just a few benefits of implementing Clearweld for the laser welding of linear or three-dimensional plastic components, parts and products.

Medical, automotive, electronics, packaging, textile, and consumer goods industries are discovering rapid, precision plastic laser welding solutions using Clearweld's near infra-red absorbing coatings, custom compounded resins or resin additives, in combination with proven laser welding and dispensing equipment.

Introducing Clearweld 900 Series:  New Clearweld Coatings at 50% to 75% Less Than Original Cost for 940-980nm lasers.Clearweld 900 Series were originally developed for industrial use in 2013, to provide the same clean, clear welds as the original Clearweld 100 and 200 Series coatings, at a lower cost for large-scale commodity applications.  NAMSA tests completed in February 2014 show negative results for cytotoxicity, making Clearweld 900 Series coatings now available for biomedical and food-related applications. Although the Clearweld medium provides a clean weld, all medical devices must be tested in whole for FDA approval.
