USB flash drive disk housings, which can either playing an electrical connector or protecting the electric circuit and chips well. With progress and innovation of technology , computer have been popularized in our daily life, so information transmission have just swaft into digitization. Application of USB flash drive disk have been used widely. This small size thing, can bring more convenience and portable to you, but the core of it is electric circuit and chips, which need a durable and strong cover to protect the core, So I think USB flash drive disk should come with a good protector.
Zinc Die Casting USB Flash Drive Disk Housings Manufacturing Process
Fllowing the below zinc die casting precision process steps :
USB Flash Drive Housing Design And Casting Die Design and Making
Following client intention, and collaborating with client engineering team, and design usb flash drive appearance and interial structure, through metal flow simulation tool, and design perfect usb flash drive housing. According to the 3d model of housing, design high effective and durable mass production casting die when the best tool steel is selected. And process the physical production casing die.
Preparation For Die Casting Process
Firstly, We have a good preparation for high effective mass production. It is need of melting Zamak 2 in the integrated furnace, filtering impurites within the molten metal by overflow method. And maintaining steady temperature molten metal in the reservior. The low melting metal require 380-420 degrees to become liquid metal, exhaust less heat energy.
Metal Part Cast Cycle
Secondly, We adopt hot chamber die casting machine to produce mass products at high efficiency. By gooseneck mechanism, the machine’s hydraulic piston push the molten metal into the pre-heated casting die under high pressure. Rely on high fluidity of molten metal, the metal flow fill the cavity of the die fully in a few seconds. The casting die accepts water cooling, and makes the molten metal solidified quickly, then ejected from the die. These cast USB flash drive disk housings are manufactured in the way.
As Cast Part Post Deburring
When Our usb flash drive disk housings is casted into the rough part by our advanced casting machines. As as-cast part, which may be deburred for removing excess gate gaps and hidden burrs. Worker use mechanical and munual options for high effective post-process. include of viberation for removing gate gap, manual filing, abrasive wheel for grinding the burrs, sand belt for grinding the burrs and cnc machining for high precision process.
The Cast Part Surface Finishes
These usb flash drive disk housings deburred may need more appeal and aethetic appearance for longnity and promotion purposes. Die casting manufacturer should deliver them to outsourcing factory for excellent surface finishing. It involves of electroplating, powder coating, printing, etching,laser engraving and anodization.
Testing And Assembly
Inspecting the outsourcing processed parts, and conduct bond power and corrosion resistance testing. Sometimes some parts require having a fit assembly for finished products and functional parts. Undoubtedly we have design and manufacture more shaped casting usb flash drive disk cover due to different demands from business partners and clients, For us, we produce zinc hard disk cover, meanwhile we also inject plastic parts for hard disk.
Die Casting USB Flash Drive Housings Are Various
Casting USB flash drive housings include of three kinds due to its functions and applications, these casting covers are all made from zinc alloy material
Long Tail Cover
This kind of hard disk cover is only decided by the flash drive disk’s appearance and designing style. some consumers like long tail flash drive disk due to his hobby and habit.
Short Tail Cover
Compare to long tail cover , there is a short tail cover, its design is depended by usage scenario and work environment, in fact , both items have a same function of storing data and transmitting data.
Turned Cover
Another kind of cover is turned cover, in general condition, it is designed to have double ports, include of USB 2.0/3.0 port and mobile smart port. So the turned flash drive disk can meet the special function of transmitting data from fixed device to mobile device.

Long Tail Disk Housings
Short tail Disk Housings
Indispensable Post Processes For Zinc Die USB Flash Drive Disk Housings
Metal casting part is rough when it is just casted, in common condition, the surface of it is very rough, with a thin sharp and burr. So it should be deburred firstly, sometimes, common worker can remove the burr with scissor and pliers, if some sharp and burr is not easily removed or repaired, so cnc machining process should be used. but also the surface of the casting part is still rough, So polishing process is necessary. I will have a conclusion, the metal casting part should be processed in the follow procedures.
Machined Finish
These zinc die casting housings are machined by machining process to gain a higher level of precision and smoother surface finish with very smooth and uniform . The rough surface of die castings should be processed by cnc machining and reach the requirements of installment.
Polished Finish
Polishing the die-cast part improves its suface smoothness and gloss . The die casting part polishing process is indispensable in treating the surface of metal casting parts. Such as Glossy, reflective surface, with a smooth texture. And make its surface more smoother.
Plated
Die-cast parts electroplated have various finishes, such as chrome, nickel and zincto plated enhances corrosion resistance, wear resistance, or aesthetics. Die Casting Parts Electroplate is super surface finish level process method for metal die casting part. Coating nickel, copper, gold and chrome on the surface of zinc die casting housing meets some requirements of the usb flash disk.
Painted Or Power-Coated Finish
Painting or powder coating finish means coating a protective or decorative layer of paint or polymer powder on the surface of the die-cast part. As Metal Casting Parts Coating, Sometimes it also need painted and powder-coated finish in order to prolong the life of the castings and decorative appearance.
Textured Or Patterned Finish
Some die-cast parts must carry with specific textured or patterned surface on it directly during the casting process. Text finish is very common surface finish, in term of making texured surface on the cavities of the mold. From sand-like textures to more intricate, decorative patterns or custom logos.
