About Rellaw Trading Co
We are a small, family-owned South African business built around a passion for precision, creativity and practical solutions.
Our journey began with a love of laser engraving and precision craftsmanship, creating personalised products and exploring what modern laser technology can achieve across different materials and applications.
As our experience grew, so did our interest in helping other laser users get better results from their machines.
Today, Rellaw Trading Co focuses on laser engraving education, digital tools, workflow systems and practical resources designed for beginners, hobbyists, makers, side-hustles and small laser businesses.
Our digital guides and systems are built around a simple philosophy:
Learn → Test → Adjust → Record → Repeat
Rather than chasing one-size-fits-all settings, we believe laser users should understand their machines, test their materials and develop workflows that produce repeatable results.
Our resources cover areas including laser settings, calibration, engraving workflows, troubleshooting, coin engraving, UV glass and crystal engraving, and laser business opportunities.
We believe good results come from a combination of knowledge, testing and experience.
As a family business, we take pride in providing practical resources, honest information and helpful customer service. Every product we develop is created with the aim of making laser engraving easier to understand, easier to test and easier to turn into something you're proud of.
