Heat-Resistant Nameplate Label Solution for Control Cabinets of an Automation Equipment Company

Client Requirements

Client Requirements and Original Solution Issues

The client's original solution had two core issues.
\nFirst, the heat resistance of ordinary coated-paper nameplates was insufficient.
\nThe original nameplate used coated-paper self-adhesive.
\nEdge lifting and image-text wear appeared in high-temperature environments.
\nThe nameplate had to be replaced every 3-6 months.
\nThis affected the integrity of the nameplate on equipment leaving the factory.

Second, different mounting positions required different heat-resistance grades.
\nInternal surface temperature of the control cabinet could exceed 80°C.
\nExternal surface temperature was affected by ambient temperature.
\nThe original solution uniformly used ordinary nameplates.
\nInsufficient heat resistance appeared at internal surface positions.

The client wanted a heat-resistant nameplate solution.
\nTo maintain durability and readability of the nameplate in high-temperature environments.

Core requirements: high-temperature resistance + long-term readability + firm adhesion.

Project challenges:
\n✓ Internal surface temperature of the control cabinet can exceed 80°C
\n✓ Ordinary coated-paper nameplates have insufficient heat resistance
\n✓ Different positions require different heat-resistance levels
\n✓ Nameplate durability affects the image of equipment leaving the factory

Solution

Solution Overview

Provided heat-resistant identification nameplate solutions for 3 control cabinet models of the client.
\nAdopted PET self-adhesive (50μ) combined with high-temperature-resistant acrylic adhesive.
\nThe face material surface was covered with a matte film (25μ) protective layer.
\nHeat-resistance grades were recommended by mounting position.
\nDigital printing supported flexible output across the 3 models.

Material Selection Analysis

Why choose PET instead of PVC?
\nPET (50μ) has a temperature range of -40°C to 150°C.
\nInternal surface temperatures above 80°C are common inside control cabinets.
\nPET has better heat resistance than PVC.
\nPET is rigid and performs well when applied to flat surfaces.

Why not continue using coated paper?
\nCoated paper has a temperature range of approximately -20°C to 80°C.
\nInternal surface temperatures of control cabinets can exceed 80°C.
\nAdhesive failure is likely for coated paper at these temperatures.

Why not choose PVC?
\nPVC (80μ) has a temperature range of -20°C to 80°C.
\nPVC has good flexibility but limited heat resistance.
\nPET is more heat-resistant and is suitable for internal surfaces of control cabinets.

Production Implementation and Quality Control

① Layout file consolidation for 3 model nameplates
\n② Incoming inspection of PET face material (thickness, transparency)
\n③ Batch inspection of high-temperature-resistant acrylic adhesive
\n④ Four-color printing
\n⑤ Matte film lamination (25μ)
\n⑥ Die-cutting (including waste stripping)
\n⑦ Sampling inspection (color, die-cutting precision, initial adhesive tack)
\n⑧ Packed by model
\n⑨ Provided mounting position recommendations in coordination with the client

Case Summary

For heat-resistant nameplates on internal surfaces of control cabinets.
\nA PET face material combined with high-temperature-resistant acrylic adhesive is a common solution.
\nThis case provided a heat-resistant nameplate solution for 3 control cabinet models of an automation equipment company.
\nPET has a temperature range of -40°C to 150°C.
\nThe matte film protective layer reduces oil and grime adhesion.
\nReadability is maintained under prolonged high-temperature environments.

LeXiang Packaging Experience

Applicable scenarios: nameplates on internal surfaces of control cabinets, industrial identification in high-temperature environments, equipment nameplates requiring long-term heat resistance.
\nMaterial recommendations: for routine conditions below 80°C choose PVC (80μ); for 80-150°C choose PET (50μ); above 150°C metal nameplates are recommended.
\nNot applicable scenarios: not suitable for adhesion to high-temperature curved surfaces, where PET rigidity creates a risk of edge lifting; not suitable for environments requiring strong-solvent resistance, where custom labels are recommended.
\nNotes: temperature differences at different mounting positions must be evaluated separately. PET face material's higher rigidity requires attention to the risk of curved-surface adhesion. Heat-resistance testing standards should be confirmed jointly by the client and the certification body.
