IQ, OQ and PQ for a Laser Marking Process: What Auditors Actually Ask For
Validating a marking process means proving the window, not the setting. How installation, operational and performance qualification apply to laser marking.
The Digital Product Passport for Plastics Manufacturers: What the Data Carrier Requirement Means
The DPP requires a durable, machine-readable carrier attached to the product and readable across its life. That is a marking requirement, written into law.
Why Paint and Ink Delaminate From Molded Plastic Parts
A decision tree for coating and ink delamination on molded plastics: find the failure interface first, then surface energy, contamination or cure.
Do You Need a Laser Safety Officer? Class 1 Enclosures and Class 4 Beams
Whether a marking cell needs a Laser Safety Officer depends on its installed classification, not the laser inside it. How that classification is decided.
Can You Laser Cut Nylon? What Works, What Melts, and How It Differs From Marking
Nylon can be laser cut with a CO2 laser, but it melts rather than vaporizes. Which lasers work, how thickness and glass fill change the edge, fume hazards, and why cutting and marking nylon are different processes.
How Long Does Plasma Surface Treatment Last? Shelf Life of Treated Plastics
Plasma-treated plastics lose surface energy within hours to weeks. Why hydrophobic recovery happens, typical windows by polymer, how to measure it and how to design the process so it stops mattering.
Laser Welding vs. Ultrasonic and Vibration Welding: When to Use Which
Compare laser, ultrasonic and vibration welding of plastics on heat generation, particulate, joint access, cycle time and part sensitivity.
Plastics Decorating Methods Compared: Pad Printing, Screen, Hot Stamping, IMD, and Laser
Pad printing, screen printing, hot stamping, in-mold decorating and laser marking compared on cost, durability, geometry and production volume.
Laser Marking PPA and High-Temperature Polyamides for E-Mobility and Under-Hood Parts
PPA and high-temperature nylons are displacing metal in under-hood and EV parts. How they mark, and why moisture and glass loading dominate the result.
