Die castings post processing innovations make the metal cast parts more durable and safety. As cast parts, which allow to have an excellent surface finish, like PVD coating, nano coating, precision cnc machining and other eco-friendly surface finishes. Compare to traditional post processing, these innovative post processes can create uniform protective layers on the cast parts. And eusure consistent high quality production at large volume.
Innovative Surface Treatment Technologies
Metal Parts surface treatment makes the parts more wear resistance and protect these parts better. Adopting advanced surface treatment technologies, uniform coating the thin coating on the metal part, brings eco-friendly and more healthful to people. The below classic items are regarded as the reference.
PVD Coating (Physical Vapor Deposition)
PVD coating can reinforce the coating on the metal parts, protect the coating on parts better. The PVD coating has the advantages of extremely thin and uniform coating, high hardness, decorative appearance of parts. So the coating treatment makes the metal part more wear resistance. Especially for zinc die casting components in gift and fashion accessories.
Nano Coating Technology
Nano coating is ultra-thin coating treatment, which protect some electroplating, painting and powder-coating effectively. The coating is transparent and colourless, without impact the color and aethetistc of the parts, and ehance additional wear resistance of the die castings. Nano coating has a strong water-repellent function, and anti-fingerprint.
High-Precision CNC Secondary Machining
In order to achieve high precision dimension of some die castings, as cast part required high-precision CNC machining to process. Especially some miniature zinc die casting components in automotive and communication industries, they maybe are used for connectors, housings and enclosures, high-precision die castings cnc secondary machining meets the requirements of their precise asseblies.
Laser Processing Technology
Laser Processing can engrave some beautiful pattern and texture on the die castings, helps business man and retailer advertisement of their commedities. Especially laser marking on die castings becomes more and more popular in die casting maufacturing. As the technology of die castings post processing innovations, which is high precision, permanent marking, and no an residues micro cutting.
Eco-Friendly Surface Finishing
The surface finishing for metal parts is eco-friendly and sustainable, and will become no toxic and more healthful. make the metal parts is more friendly to human being. like the below innovative surface treatments.
- Using Trivalent chromium plating replaces traditional hexavalent chromium.
- Water-based coatings which low VOC emissions.
- Electro-less plating, more uniform coating thickness.
Overview, the above die castings post processing innovations can treat metal parts, and even coat the thin protective layer on the parts, makes the parts longer life time. More eco-friendly, more healthful die casting parts makes humen being life comfortable.
Die Casting Manufacturer Offers Consideration Die Castings Post Processing Services
The die casting manufacturer, focus on the precision cast of die casting parts, while own around die castings post processing innovations technology, offer precise die casting parts and follow strict quality control system, and eusure consistent quality die casting part at large volume at high efficiency.
Viberation Machining Process
As cast parts are rough, and carry with many flange on parting line, and excess burrs, the viberation machining process can remove the excess burrs and flanges on parting line, and makes the cast part fine surface finish. Put these as cast parts on the jig one by one, and the machine generate high frequency viberation, remove the excess burrs on the cast part.
Precision CNC Machining
Precision CNC machining processes tight tolerance dimensional miniature die casting. Such as micro usb flash drive disk housings and enclosures. Each part for the setting must be assemblied smoothly, and the numerial control lathe can process the metal parts in accuracy. It can offer consistent high quality precise metal parts at high efficiency at mass production.
Laser Marking On Die Castings
Professional laser marking on die castings. we also like to share our previous work experience with everyone this time. For laser marking on die castings, desinger create cool laser marking documents, and using the advanced CO2 laser marking machine to engrave cool logos and patterns on the surface of die castings.
Mirron-Reflect Polishing
polishing metal after casting is a multi-step process that improves the surface finish, removes imperfections, and can give the metal a smooth, mirror-like shine. Such as Zinc die casting parts polishing process, up to mirror-reflect result and accept shiny chrome plating or other high-end plating layer. Aluminum die casting require impregnation and seal the porosity on it, and allow a good striking zin adhesive layer, and accept more high-end plating.
Hot-dipping Coating
This method in which dipping metal into a molten bath of coating material (like zinc or aluminum) ,and form a protective layer. The coating process is used for galvanized steel structures, automotive components, and roofing materials. It makes the metal part less rust, and generate a high effective protective layer on the surface of metal parts.
Die Castings Post Processing Innovations Project Case
Laser Marking on zinc die castings is classic project case, which using precision laser engraving technology and advanced laser equipment, engraving customized patterns and logos on miniature usb flash dirve disk housings, creates permanent marking on the metal parts, allows proper color, this brings great help for the advertisement of the miniature flash drive disk. Our outstanding projects as the below pictures.
Conclusion
In summary, the above die castings post processing innovations provide more durable and friendly to people. Sometimes enhance wear resistance of the miniature cast part, on which die casting manufacturer coat the effective metal material coating, and meet different requirements of the metal parts. Depends on the specific requirement from the client, the proper die casting post processing method can be chosen, and finish the project completely.
