Two suppliers submit weathering data for the same OEM program. Both use xenon arc equipment. Both run the same number of hours. One submission is accepted. The other is rejected. The difference isn’t the equipment or the hours. It’s the method. The rejected lab ran a general xenon cycle. The accepted lab ran the specific…
Every material that goes into a vehicle was qualified against a specification. Every specification was written by an engineer. Every test that confirmed compliance was run in a lab like this one. National Engineers Week 2026 runs February 22 through 28 under the theme Transform Your Future. We think about that theme every day. GPTesting…
A dashboard can look perfect at room temperature, ship on time, and still crack the first week it sees a real winter. The crack didn’t start in January. It started months earlier, when the part expanded under summer solar load, contracted overnight, and repeated that stress cycle until a tiny defect finally had enough leverage…
Your part passed every mechanical test on the list. Then the OEM auditor walked the line, held it up to the light, and called it a fail. A gloss reading of 5.0 when the spec said 2.5 to 4.0. That’s not a cosmetic issue. It’s a real rejection, and it happens more than most engineers…
UV damage is relentless, and it rarely shows up on day one A polymer part can look flawless at launch and still fail in the field. UV damage works like slow mechanical fatigue: you do not notice the early hits, then one day the surface chalks, the color shifts, the gloss drops, or a once-tough…
Let’s start with what we know. Ghesquiere Plastic Testing, Inc. in Harper Woods, Michigan has successfully renewed its A2LA Accreditation for ISO/IEC 17025:2017 compliance in mechanical testing. Our accreditation remains in effect through December 31, 2027 under A2LA Certificate No. 0079.01. For current and prospective automotive clients, this is not a ceremonial badge. It’s independent…
Every product tells a story the moment someone touches it — whether it’s a new car dashboard, a smartphone case, or a kitchen appliance panel. That story can change quickly when scratches, scuffs, or surface wear start to appear. For manufacturers, surface durability is about more than aesthetics — it’s about perception, longevity, and brand…
Introduction Every product — from automotive components to consumer goods — depends on one critical factor: the strength and reliability of the materials that make it. Whether it’s a plastic housing, a rubber seal, or a metal bracket, understanding how materials perform under force is vital to ensuring safety, consistency, and customer satisfaction. This is…
In the competitive world of manufacturing, ensuring a product’s performance over its lifespan is non-negotiable. Whether it’s the plastic trim on an automotive dashboard, a specialized exterior coating, or a marine textile, real-world exposure to the elements—sunlight, heat, and moisture—is the ultimate test of durability. When it comes to predicting how materials will perform over…
