Laser Marking vs. Labels on Electrical Appliances

Laser markers are used to mark precautions and specifications directly onto electrical appliances. Laser light discolors resin, resulting in clear marking that doesn't fade. Electrical appliances are marked with a wide variety of information. Common examples are product specifications, product precautions and information in foreign languages for overseas sales.

Application Explanation

Lighting equipment

Battery pack

Key Laser Marking Advantages

Quality
Clear marking that doesn't fade is possible, even when the laser marker is used for a long period of time.

Cost
The running costs of labels, which increase according to the number of sheets used, are eliminated. The cost of creating a plate template when changing display details is also eliminated.

Work efficiency
Eliminate the need for tooling changes, label inventory management and plate creation.

Environment
Eliminating waste, such as label backings, contributes to environmental health and safety.

Laser Markers vs. Labels on PCBs

Laser markers are used to mark lot numbers and 2D codes for process management directly onto PCBs. This enables accurate traceability for PCBs, which have a high component density and no space for labels. Considering the need for thin products, laser markers also eliminate the need for extra label space.

Application Explanation

Laser marking on a PCB

Inkjet printer marking on a PCB

Key Laser Marking Advantages

Quality
Direct marking enables accurate traceability for PCBs, which have a high component density. Label thickness is also eliminated in order to make products thinner.

Cost
Increased production volume typically leads to increased label costs. Laser markers eliminate these running costs by removing the need for expensive, heat-resistant labels.

Work efficiency
It is possible to greatly reduce the amount of work—such as tooling changes for different models, label inventory management, and the creation of a plate when changing the details—required.

Environment
The elimination of garbage such as label backings contributes to environmental initiatives (CSR).

Laser Marking Vehicle Nameplates

Traditional vehicle nameplates are now being created with laser markers. Laser marked nameplates provide support for multiple vehicle models and act as a countermeasure against forgery. Laser marked nameplates halve the amount of materials required for production, which greatly reduces both costs and lead time.

Application Explanation

Nameplate

Key Laser Marking Advantages

Quality
It is impossible to cleanly remove a laser marked nameplate once it has been placed onto a vehicle, which helps prevent forgery. Laser marked nameplates are also highly resistant to heat, oil and water, so they can clearly display their information for a long time.

Cost
There's no need to create a plate for new vehicle models and languages. Simply produce what you need, when you need it.

Work efficiency
There's no need to stop production while marking; products can be marked while being conveyed. Overall productivity also improves since the marking contents can be changed with the touch of a button.

Environment
There is no need for an excessive inventory of labels. This makes it possible to save resources, which contributes to environmental initiatives (CSR).

Improving Barcode Labels

Laser markers are used to create labels on cardboard and cosmetic boxes. These packages require a wide array of data (such as shipping addresses and management numbers). In order to correctly mark each package, it was once necessary to change the type of label affixed to the package or print multiple labels on the same box. Laser markers eliminate these problems by reducing the required number of label models and the work involved with inventory management.

Application Explanation

GS1 DataBar marking

Carton

Key Laser Marking Advantages

Quality
The problems of affixing the wrong label and the labels peeling off are both eliminated.

Cost
Physical label costs are greatly reduced. Consolidating label models also reduces inventory and printing costs.

Work efficiency
It is possible to greatly reduce the amount of work—such as tooling changes for different models, label inventory management, and the creation of a plate when changing the details—required.

Environment
The elimination of garbage such as label backings contributes to environmental initiatives (CSR).
