On winter mornings, it takes time for the furnace to warm up, and the luster of the parts poured before reaching the set temperature diminishes. This explains the management of furnace startup that changes with the seasons.
Only the parts baked on winter mornings lack luster. When lined up with the afternoon parts, the difference is clearly noticeable. 【First, please look here】 □ Parts immediately after startup have lower luster → They are being processed before the furnace reaches the set temperature □ Only the parts close to the furnace entrance have low luster → They cool down with outside air, causing uneven temperatures inside the furnace □ Parts with low luster feel somewhat soft to the touch → They have insufficient curing, and the coating has not fully solidified 【Why does this happen?】 In winter, the outside air is cold, and it takes longer for the furnace to warm up compared to summer. Even if the thermometer shows the set value, it does not guarantee that the entire furnace is warm. 【Countermeasures that can be implemented starting today】 1. Extend the furnace startup time during winter 2. For the first parts, check the luster and hardness with a test plate before processing 3. Record the temperature at different locations inside the furnace 【Free materials】 We have compiled the response details for baking paint in the related catalog "Baking Paint Services."

Company information
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.
