What is the baking temperature for factory paint?
3 Answers
Factory paint needs to be baked at temperatures between 130°C and 180°C, using a cross-linking hardening method. The paint spraying process used in vehicle manufacturing adopts an assembly line approach, with all temperature controls managed by computers and application performed by robotic arms, ensuring extremely uniform coverage with virtually no imperfections. Below are precautions for vehicle painting: 1. Choose a repair shop with an independent enclosed paint baking room for painting. Car painting is a significant maintenance task, and any imperfections during the process can greatly affect the vehicle. 2. Avoid driving the car within 24 hours after painting and try to prevent the vehicle from coming into contact with moisture.
The original factory paint is baked during the automobile manufacturing process, typically at temperatures ranging from 120 to 160 degrees Celsius, with the ideal range around 140 degrees Celsius. This high temperature ensures perfect fusion between the paint and primer, forming a hard, durable coating after complete curing, with excellent gloss and scratch resistance. Factories use specialized ovens with precise time control of about 30 minutes, facilitating rapid reaction of the paint layers into a film, avoiding issues like bubbling or peeling. In contrast, aftermarket paint jobs are done at much lower temperatures, around 80 degrees Celsius, which, while convenient and quick, result in poorer durability and are prone to discoloration or cracking. From my experience, original factory paint acts like a vehicle's armor. Pay extra attention during daily parking and car washes to avoid scratches from branches or hard objects, ensuring the car's appearance lasts longer.
When it comes to the temperature of factory paint, remember that the oven settings in the factory often exceed 140 degrees Celsius. This temperature helps the paint harden like stone. Last time I visited an auto plant, the video showed the thermometer steady at around 150 degrees, with the entire process being quick and efficient, resulting in a single-formed paint layer with a glossy finish. You can really feel the advantages of factory paint in daily driving—like how water beads roll off quickly in the rain, and cleaning the car takes little effort. Aftermarket paint jobs, on the other hand, only reach around 80 degrees. They’re cheaper but less durable. On my own car, the repainted area always turns slightly yellow over time, so I avoid using a high-pressure washer directly on it during car washes—it’s a simple way to extend the life of the original paint.
