Материалы
Техническое описание и стоимость
В обработанном виде
Металлы и пластмассы
Черновая обработка непосредственно на станке с ЧПУ. Самый экономичный выбор при самых жестких допусках. Присутствуют видимые следы от инструмента.
Гладкая обработка
Металлы и пластмассы
Обработка при меньшей скорости подачи. Менее заметные следы от инструмента, лучшие уплотнительные свойства и снижение трения.
Полировка
Все материалы
Сглаживание для удаления следов от инструмента. Незаменима для оптических деталей, пресс-форм и уменьшения трения.
Обработка бисером
Пластмассы
Бомбардировка стеклянными шариками для равномерного матового покрытия. Скрывает следы от инструментов. Примечание: влияет на размеры.
Гашеный
Пластмассы
Пакетный процесс с использованием вибрирующей среды. Удаление острых кромок (снятие заусенцев) и выравнивание геометрии.
Анодирование Тип II (матовое)
Алюминий
Коррозионностойкий оксидный слой. Матовая поверхность достигается путем дробеструйной обработки перед анодированием. Непроводящий.
Анодирование тип II (глянцевое)
Алюминий
Стандартное анодирование типа II, нанесенное на полированную/гладкую поверхность. Яркий, блестящий внешний вид.
Анодирование тип III (твердое покрытие)
Алюминий
Толстый, плотный оксидный слой (25-50 мкм). Исключительная износостойкость (60-70 HRC). Ограниченный выбор цветов (темный).
Порошковое покрытие
Все металлы
Сухой порошок, расплавленный под воздействием тепла. Прочная, толстая пластиковая оболочка (~80 мкм). Превосходная прочность по сравнению с мокрой краской.
Черный оксид
Конверсионное покрытие. Антибликовое покрытие, слабая коррозионная стойкость (нуждается в масле). Незначительное изменение толщины.
Heat Treatment
Mold Steels，High-Speed Steel (HSS)
Heat treatment and deep cryogenic treatment improve hardness, wear resistance, toughness, and dimensional stability, helping extend the service life of molds and precision components.
Nitriding
Punches, dies, mold inserts,
A surface hardening treatment that improves surface hardness, wear resistance, and fatigue strength, helping extend the service life of molds and tooling.
PVD Coatings

Часто задаваемые вопросы
After receiving your CAD files or drawings, our engineering team reviews key factors such as geometry, tolerances, wall thickness, tool accessibility, radii, threads, and material requirements.
If potential manufacturing issues are identified, we provide practical recommendations on design optimization, tolerances, machining processes, and material selection to help ensure stable and repeatable production.
This early review helps reduce design changes, control manufacturing costs, and improve production efficiency before machining begins.
Lead times depend on part complexity, tolerance requirements, material, surface treatment, and order quantity. For most prototype and small-batch projects, production can typically be completed within a few working days, while complex components or multi-process projects may require additional time.
For urgent projects, expedited production may also be available. To provide an accurate lead time, simply send us your 2D drawings or 3D files, material requirements, and quantity. Our engineering team will review the project and confirm the estimated lead time during the quotation process.
Yes. We can provide material certificates, inspection reports, and other quality documentation based on project requirements. Our inspection records cover key dimensions, tolerances, hardness, and other specified requirements to support full quality verification and traceability.
The cost depends on factors such as part geometry, material, tolerances, surface treatment, machining processes, and order quantity. We provide competitive pricing based on your specific requirements while maintaining consistent quality.
Simply send us your 2D drawings or 3D files, material requirements, and quantity, and our engineering team will review the project and provide a detailed quotation.
At Skypu, every part undergoes dimensional inspection, material verification, and final quality control. Critical features can be inspected 100%, with inspection reports available upon request to help ensure parts meet the agreed specifications.
If a delivered part does not meet the specified requirements, our quality team will promptly review the issue and identify the root cause. Customers can provide measurement data, photos, or other inspection results to support the investigation.
We take quality issues seriously and work with our customers to determine the appropriate solution, which may include rework, replacement, refund, or credit, depending on the specific situation. Corrective and preventive actions are documented when applicable to support traceability and continuous improvement.
