As soon as material for a project is received, it has to be inspected and tagged as approved before it can be used.
QUANTITY & MEASUREMENTS
We begin by checking that the quantity and measurements of material received matches what we need as specified by our bill of materials.
Next, we check to ensure that the alloy of material we received is in fact what is called for by the project.
Finally, we inspect the material to ensure that the material is in good aesthetic shape and that there are no unwanted scratches or visual defects.
FIRST ARTICLE INSPECTION
The First Article Inspection focuses on dimensions and tolerances, fit and function, aesthetics, weld quality, material verification, product testing, and documentation and traceability.
In-Process Inspections focus on checking dimensions and tolerances, aesthetics, weld quality, material verification, and documentation and traceability.
The first thing we inspect is paint thickness. By using an electronic device, we can efficiently and accurately determine that the millage of the products coating is within the specified tolerance.
DEGREE OF CURE
The MEK test is an ASTM standard. We begin by dipping a cotton swab with Methyl Ethyl Ketone (MEK) before firmly pushing on the product surface and rubbing back and forth. In general, 25 double rubs are performed. Pressing all the way up and all the way down is classed as one double rub. The number of rubs that a coating will pass will vary between product.
Finally, we use a cross-hatch adhesion test to ensure that the painting has good adhesion. We begin by cutting a cross-hatch pattern into the coating of a surface on the product. We then apply pressure sensitive tape to the cross-hatching. Lastly, we remove the tape from the surface. If no paint comes off with the tape, then paint adhesion is good. One square on the tape is okay, but if multiple squares come off, then the coating isn’t properly adhering to the surface and our team will then take the required steps to correct the paint adhesion.
The Final Inspection focuses on dimensions and tolerances, fit and function, aesthetics, weld quality, material verification, product testing, and documentation and traceability.
