Does removing manual steps in manufacturing improve product quality for the consumer?
Arburg, Kebo, and Matriq have demonstrated a system for marking auto-injector housings with Data Matrix codes during the moulding process at the Fakuma 2026 trade fair. The technology integrates the identification step directly into the production cell.
Why it matters
By embedding identification directly into the component, manufacturers can eliminate secondary processing steps like laser engraving, which reduces cycle times and overall production costs. The process is specifically designed for high-precision medical-grade applications.
The system utilizes an Allrounder 570 A machine with a 4-cavity mould and an insert containing 144 microheaters, each measuring 0.28 by 0.28 millimetres. The process maintains ISO Class 7 cleanroom compliance and operates at mould temperatures up to 100 degrees Celsius.
The players
Arburg
A manufacturer of high-end injection moulding machines and industrial automation systems.
Kebo
A precision mould maker specializing in high-performance tools for medical and packaging applications.
Matriq
An engineering firm focused on innovative surface marking and traceability technologies for plastic parts.
The details
The technology uses a dynamic mould insert to create geometric structures on the component surface during injection, rather than relying on color contrast for visibility. A central database syncs machine controller data with the Matriq system using an OPC UA interface—a standard for industrial communication—to ensure traceability of the housing components. This setup uses a 2,000 kN clamping force and achieves an 11-second cycle time per production run.
Timeline
The demonstration occurred at the Fakuma 2026 trade fair.
The Tech Race
This development moves beyond traditional post-moulding laser engraving by integrating data marking directly into the injection cycle. The field is increasingly shifting toward such integrated traceability, where identification is a function of the mould itself rather than a secondary station.
This technology is intended for producers of high-precision components like medical auto-injectors where traceability is required. Adoption allows manufacturers to reduce energy consumption and shrink their cleanroom footprint by removing external marking machinery.
The takeaway
The integration of Data Matrix marking directly into the mould cavity represents a significant efficiency gain in medical device production. Future development efforts will focus on the deployment of an active cooling solution for the mould insert to further stabilize high-temperature operations.
