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 pretreatment, surface residue, moisture, substrate outgassing, or compressed air contamination. Improve pretreatment, drying, and compressed air filtration.<\/div><\/details>\n      <details class=\"faq-item\"><summary>Why is the coating uneven?<\/summary><div class=\"faq-answer\">Uneven coating can be caused by poor grounding, unstable powder supply, wrong spray gun distance, difficult part geometry, poor booth airflow, or excessive line speed.<\/div><\/details>\n      <details class=\"faq-item\"><summary>Why are impact strength and adhesion poor?<\/summary><div class=\"faq-answer\">Poor adhesion or impact strength is usually linked to weak pretreatment, oil residue, under-curing, wrong powder choice, or insufficient actual workpiece temperature.<\/div><\/details>\n      <details class=\"faq-item\"><summary>Why is powder supply uneven?<\/summary><div class=\"faq-answer\">Uneven powder supply may be caused by poor powder fluidization, blocked hoses, unstable compressed air, worn pump parts, or damp powder. Check powder supply system and air quality.<\/div><\/details>\n      <details class=\"faq-item\"><summary>Why is powder flying and adsorption poor?<\/summary><div class=\"faq-answer\">Poor adsorption can be caused by weak grounding, wrong electrostatic voltage, high humidity, poor powder quality, incorrect spray distance, or excessive booth airflow.<\/div><\/details>\n      <details class=\"faq-item\"><summary>What information should I send for a custom electronics coating line quote?<\/summary><div class=\"faq-answer\">Send product photos or drawings, maximum passing size, workpiece material and weight, monthly output, coating color and finish standard, pretreatment method, factory layout, energy source, and target installation time.<\/div><\/details>\n    <\/div>\n  <\/div>\n<\/section>\n\n<section class=\"section-padding\" id=\"contact\">\n  <div class=\"container\">\n    <div class=\"cta-panel\">\n      <div>\n        <h2>Need an Electronic Products Powder Coating Line Layout?<\/h2>\n        Send your product drawings, maximum passing size, monthly output target, coating standard, factory layout, energy source, and automation plan.
