Electric Discharge Machining Surface Finishes
Мы обеспечиваем эстетическую и эксплуатационную отделку: анодирование, полировку, пескоструйную обработку, нанесение покрытий и термообработку. Давайте найдем подходящий вариант!
Как обработано
Такая обработка является грубой и имеет следы от инструмента, представляя собой самую базовую форму обработки поверхности без дополнительной отделки или полировки.
Анодирование
Он создает защитный оксидный слой на алюминии, повышая коррозионную стойкость и твердость, а также позволяя окрашивать его для улучшения внешнего вида.
Полировка
Полировка сглаживает поверхности до блеска, улучшая внешний вид и уменьшая шероховатость, а также обеспечивая некоторую защиту от коррозии.
Матовая отделка
Матовое покрытие с тонкими параллельными линиями придает текстуру, улучшает захват и уменьшает отпечатки пальцев.
Пескоструйная обработка
Пескоструйная обработка использует воздух под высоким давлением и абразивные частицы для очистки или текстурирования поверхностей, повышая адгезию покрытий.
Электрополировка
Электрополировка - это электрохимический процесс, который сглаживает и осветляет металлические поверхности, устраняя дефекты и повышая коррозионную стойкость.
