Inclusions, adhesion loss, colour variation or inconsistent hardness: the visible defect is the starting point. GRO Check360™ examines coating, material, pretreatment, application and curing conditions through a test plan built around your question.
Recurring scratches, dust inclusions, blistering, adhesion loss or colour differences.
Varying hardness, incomplete curing or inconsistent film thickness.
New products, materials or installations with an unstable process.
Preparation for customer inspections, unexplained rework or missing reproducible tests.
A coating manufacturer or material supplier needs to clarify a customer complaint technically: does the cause lie in the material, its application or the production process?
WHO IS IT FOR?
Who GRO Check360™ is for.
For operations with industrial coating lines and those responsible for coating quality, processes and technical equipment.
Powder and wet coating shops
Resolve recurring defects such as inclusions, adhesion, colour or hardness problems. We check the whole chain: preparation, application, curing and equipment condition.
Coating suppliers
We help establish whether a complaint really stems from the coating or from substrate preparation, application or curing at the customer’s site.
Material suppliers
We establish whether the cause lies in the material itself or, for example, in its temperature, moisture or preparation at the time of application.
Companies outsourcing coating
On-site quality assessment at the external coating shop and support in resolving quality issues between client and contractor.
Manufacturers of coating machinery and equipment
We help establish whether a problem lies in machine parameters or condition, or in the material, process or operation.
Consulting firms
Support when new standards or recommendations in a coating shop do not deliver the expected effect. We establish where and why the process departs from the plan.
TYPICAL SITUATIONS
When a conversation can help.
Recurring coating defects such as inclusions, adhesion loss, discolouration or inconsistent hardness.
Uncertainty about the interaction of materials, surface preparation, application and oven parameters.
A need for a documented assessment with measurements and prioritised recommendations.
AT THE OVEN. ON THE LINE. IN THE PLANT.
The work in practical terms.
Investigate coating defects, materials, pretreatment and oven parameters together. Use findings and measurements to define practical next steps.
01
Coating on the finished product
Compare colour against customer or reference samples before and after curing. Visually document scratches, inclusions, discolouration and texture deviations. Examine adhesion, hardness or scratch resistance, impact resistance and film thickness under an agreed test plan. Keep the connection to the part and process conditions traceable.
02
Curing oven and equipment condition
Record temperature history with a suitable data logger and relate it to material requirements. Review airflow, temperature differences and the condition of burners, nozzles, guides and chains. Include filters, fans, walls and floor cleanliness; vibration and coating-zone air quality where needed. Compare with OEM documentation.
03
Materials and documentation
Review coatings, hardeners, thinners, additives, cleaning agents and auxiliary materials. Check application parameters against TDS, and examine shelf life, storage and system compatibility. Include safety data sheets (SDS), supplier documents and available quality evidence.
04
Surface preparation and environment
Document condition after sand or shot blasting. Depending on substrate and question, plan dust/tape tests, soluble salts using the Bresle method, conductivity tests on suitable samples and Dyne wetting tests. Investigate part temperature, humidity, dust and air movement, chemical preparation and drying time, temperature and method. Not every method suits every material.
05
Application, ergonomics and occupational safety
Observe tool arrangement, work sequence, posture and repetitive loads. Review actual PPE use and condition, material routes, markings and hazard zones. Compare fumes, burn and slip hazards and machine instructions with actual work. Feed these observations into quality and safety actions.
06
Report, causes and practical priorities
Assign measurements, photos and agreed video records to the investigated areas. Separate confirmed findings, causal hypotheses and further tests. Prioritise immediate corrections, training, TPM, cleaning and technical measures; state the origin and comparability of reference data.
Methods and technical foundations
Colour/ΔE, adhesion, hardness, impact resistance and film-thickness tests under an appropriate test plan.
Temperature history, airflow and optional vibration diagnosis in relation to material and equipment condition.
TDS/SDS comparison, surface and environmental tests and observation at the workstation.
TPM, Lean and OEM requirements connect technical findings with operation and maintenance.
Test plan, part/sample identification and agreed test results.
Photo and agreed video records, temperature and other measurement data.
Technical assessment with causal hypotheses, open questions and prioritised recommendations.
Action plan covering corrections, cleaning, training and process control; before/after comparison when commissioned.
Delivery scope matched to the operation
Diagnosis, report and review
GRO investigates the agreed areas and hands over findings, measurements and an action plan. Your operation then decides priorities and implementation.
Diagnosis followed by implementation
In an extended assignment, GRO implements agreed corrections with the client’s team: for example oven regeneration, TPM-Light, checklists, training or fine adjustment. Additional work is identified in the scope.
GRO / HANDOVER
What you receive after the assignment
You receive a connected view of product, material, pretreatment, application, oven and working environment. The report identifies supported causes, questions still requiring investigation and useful implementation steps. The assessment may concern material-related, process-related or interacting causes; no cause is predetermined.
Questions about the scope
Does Check360 only examine coating defects and the oven?
No. The original scope covers the whole coating process, including materials, surface preparation, environment, ergonomics and occupational safety. The tests are selected for the installation and question.
What is needed before the visit?
Equipment access, a technical contact and available TDS, SDS, OEM documents or internal instructions. Known defects and comparison parts help preparation. Visit and report dates are confirmed with the test plan.
Can Check360 also support coating and material suppliers?
Yes. GRO supports technical clarification of coating problems by considering the material and actual process conditions. Supplier documents, application, preparation, oven and environment are considered together within the agreed scope. Contacts, access and documents are agreed with the parties involved. Confirmed findings remain distinguishable from hypotheses and further investigation needs.
