The temperature difference inside the summer baking furnace disturbs the film thickness.
In the summer when the outside temperature rises, temperature variations inside the furnace lead to issues with film thickness. This explains the causes and management methods.
During the summer, isn't there an increase in the variation of film thickness? The cause may be the temperature differences inside the curing oven. On days when the outside temperature is 35 degrees, the temperature difference inside the oven can expand to twice the normal range. ────────────── ■ Cause of Occurrence In summer, the high outside temperature can easily create a temperature difference between the entrance and the back of the oven. When the temperature is not uniform, the curing speed varies by area, leading to uneven film thickness. ■ The Truth It is not uncommon for temperature management inside the oven, which was not an issue in winter, to become unstable only in summer. The position of the ventilation openings that draw in outside air also affects this. ■ Improvement Measures Measure the temperature at multiple locations inside the oven and revise the settings specifically for summer. Adjust the timing of ventilation to keep the temperature difference inside the oven within plus or minus 5 degrees. Please utilize the materials for reviewing the curing conditions in summer.

We are not just a "subcontracted painting factory." Established in 1958, our company has a foundation of painting technology and also specializes in chemical treatment, stripping, and cleaning, functioning as the "external surface treatment department" in your organizational chart. Based on our philosophy of "preparation is eight-tenths of the work," we emphasize participation from the "upstream process" before the drawings are finalized. We conduct test painting on a wide range of metals and difficult materials, and we produce the entire process from assembly, packaging, to delivery, thereby reducing your management workload. Additionally, by being able to perform zinc phosphate treatment in-house, we achieve stable painting quality. Furthermore, our micro-heating stripping technology, which does not use chemicals, maintains the electrical state of the "jigs (hangers)" that influence painting quality. Our approach of "pre-treatment determines painting quality" ensures the stability of the paint film during mass production. Rather than simply "applying specified standards," we work backwards to achieve optimal painting specifications and prevent scratches during transportation, sparing no effort in thorough discussions from the outset. This diligent preparation is the shortest path to preventing rework and minimizing total costs. From the development stage, please utilize the expertise of our specialists as part of your production line.
