The reference passing size is 8 \u00d7 2.5 \u00d7 3 m.<\/div><\/details>\n      <details class=\"faq-item\"><summary>Why is walk-in manual spray room suitable for advertising sign coating?<\/summary><div class=\"faq-answer\">Advertising products are often oversized, project-based, and irregular in shape. A walk-in manual spray room gives operators space and flexibility to coat large billboard frames, signboards, and display equipment.<\/div><\/details>\n      <details class=\"faq-item\"><summary>What is the reference production capacity?<\/summary><div class=\"faq-answer\">The reference advertising frame coating line is designed for about 50,000 pieces per month, depending on product size, operator quantity, curing time, hanging method, and production schedule.<\/div><\/details>\n      <details class=\"faq-item\"><summary>Is powder coating suitable for outdoor billboards?<\/summary><div class=\"faq-answer\">Yes. With suitable surface preparation, outdoor-grade powder, correct film thickness, and stable curing, powder coating can provide good corrosion resistance and durable appearance for outdoor advertising frames.<\/div><\/details>\n      <details class=\"faq-item\"><summary>Why is the coating not shiny enough?<\/summary><div class=\"faq-answer\">Low gloss may be caused by incorrect curing temperature, insufficient curing time, poor powder quality, surface contamination, or uneven oven temperature. Check powder formula, actual part temperature, and curing oven balance.<\/div><\/details>\n      <details class=\"faq-item\"><summary>Why does the coating change color?<\/summary><div class=\"faq-answer\">Color change can come from over-curing, excessive oven temperature, powder contamination, mixed colors, or unstable heat control. Clean the powder system and verify the curing profile.<\/div><\/details>\n      <details class=\"faq-item\"><summary>Why is the coating surface orange peel?<\/summary><div class=\"faq-answer\">Orange peel may be related to excessive film thickness, powder formulation, poor leveling, wrong curing profile, or uneven heating. Adjust spray thickness and confirm curing temperature and time.<\/div><\/details>\n      <details class=\"faq-item\"><summary>Why do concave holes, bubbles, or pinholes appear?<\/summary><div class=\"faq-answer\">These defects may be caused by oil, water, dust, poor polishing, surface residue, moisture, substrate outgassing, or compressed air contamination. Improve pretreatment, drying, and booth cleanliness.<\/div><\/details>\n      <details class=\"faq-item\"><summary>Why is the coating uneven on large frames?<\/summary><div class=\"faq-answer\">Uneven coating can be caused by poor grounding, wrong spray angle, unstable powder supply, difficult frame geometry, operator inconsistency, or oversized workpiece movement. Hanging and grounding should be checked first.<\/div><\/details>\n      <details class=\"faq-item\"><summary>Why does the coating fall off?<\/summary><div class=\"faq-answer\">Coating peel-off is usually caused by poor surface preparation, rust or oil residue, weak polishing, under-curing, poor grounding, or powder unsuitable for the substrate and use environment.<\/div><\/details>\n      <details class=\"faq-item\"><summary>How should I choose oven size for advertising frames?<\/summary><div class=\"faq-answer\">Oven size should be based on maximum passing size, frame weight, metal thickness, curing time, loading spacing, and production output.
