Mechanical Engineering & Plant Engineering
Engraving materials for durable technical identification, control panels, front panels and labelling in mechanical and plant engineering. Suitable plastics and metals enable machines, assemblies and technical systems to be identified precisely, clearly and permanently. Flexible, self adhesive engraving materials are also available for curved surfaces and retrofit identification.
Durable Identification for Machines and Technical Systems
In mechanical engineering, identification must remain clearly legible and unambiguous even after long term use. Depending on the application, machine plates, control panels, front panels, scales, warning notices or identification for assemblies and systems may be required.
Important factors when selecting a material include the processing method, UV resistance, weather resistance, temperature, mechanical stress, surface finish, material thickness and mounting method.

What Should Be Considered for Identification in Mechanical Engineering?
Application Environment
Interior or exterior use, moisture, UV radiation, temperature fluctuations and possible chemical or mechanical stress all influence the choice of material.
Readability & Contrast
Function labels, scales, serial numbers and safety information should remain clearly legible even at small character sizes. Material colour and engraving contrast are therefore important selection criteria.
Processing Method
The material should match the available processing technology. LaserAcryl 1 can be laser and rotary engraved. LaserFoil is designed for laser engraving and laser cutting. PLY 2 is suitable for rotary and laser engraving. Aluminium G (matt) is particularly suited to rotary and diamond engraving, while AluSign is developed for high contrast laser marking.
Material Thickness & Design
Thin materials are suitable for flat identification and front panels, while thicker materials can provide greater structural stability. Format, drilled holes and installation conditions should be considered when selecting the material.
Mounting
Depending on the application, identification plates can be bonded, screwed or riveted in place. Self adhesive versions are also available for selected materials. LaserFoil is designed as a thin, flexible material with a self adhesive backing.
Variable Identification
Series production may require individual numbers, QR codes, machine IDs or other variable data. The material should support precise and repeatable processing.
Custom Cuts and Further Processing for Mechanical Engineering
Many INNOGRAV engraving materials can be ordered as full sheets, strips or custom cut pieces. This makes it possible to process technical signs, front panels and identification efficiently in a wide range of formats.
Depending on the material and version, additional processing such as drilled holes, rounded corners or self adhesive backing is available.
Nameplates for Machines and Systems
Nameplates are a key application for the clear identification of machines and technical systems. More information on materials for manufacturer information, serial numbers, performance data and QR codes can be found on our dedicated page for nameplates and machine plates.
