Industrial Laser Cutting Machine Complement Mechanical Expertise

How industrial laser marking machines transformed LJ Industries

LJ Industries has built a reputation for precision mechanics, machining, welding, and assembly of complex industrial components. In response to growing client demands for traceability and enhanced part customization, the company expanded its capabilities by incorporating Trotec’s high-precision laser systems into its production workflow.

“Our core business was originally purely mechanical. But our clients‘ growing traceability requirements quickly led us to invest in laser technology,” says Laurent Perrissin-Fabert, co-manager of LJ Industries. LJ Industries discovered Trotec’s high-precision engraving solutions at the C!Print trade show in Lyon. “Trotec offered to carry out test engravings on our parts. The results were validated by our end customer, which convinced us of the reliability and accuracy of their machines,” recalls Philippe Renoud Grappin, co-manager. Since then, several Trotec laser machines have been integrated into LJ Industries’ production workflow, enabling superior precision and efficiency.

Precision laser technology at the heart of production

LJ Industries relies on four Trotec laser machines, including:

• Speedy 100 and Speedy 400 CO₂ lasers for versatile cutting and engraving tasks on various Trotec materials, enabling in-house production of personalized items and essential positioning jigs for flexible small-to-medium manufacturing runs.
• SpeedMarker 1300 fiber laser machines that deliver precise, durable, and repeatable metal markings at high speed, fully integrated into the production line to ensure compliance and traceability.

Trotec’s laser software Ruby® has also enhanced operational efficiency, enabling the entire team to manage laser workflows more flexibly and smoothly.

Laser Technology as a catalyst for industrial transformation

Initially introduced to fulfill traceability requirements, laser technology now forms a central pillar of LJ Industries’ industrial strategy. By replacing traditional machining steps with faster, more precise laser processes, the company has improved cost-efficiency, increased flexibility, and expanded its range of services — from technical engraving to full part customization.

This success story exemplifies how Trotec’s laser machines lead the charge in industrial innovation, empowering manufacturers to redefine their production capabilities and strengthen their market position.
