The head arm assembly is moved by an HDD actuator. Its duty is to fully regulate the hard drive head assembly in addition to starting and securing continuous movement. For hard drives to carry out their fundamental functions, the security and management of this movement are of utmost importance.
Despite not being airtight, hard drives are still sealed. They are constructed to avoid pollution. The read/write heads are around 6 microns from the platters, therefore a very microscopic particle could result in a head crash. This shows that a contaminant doesn’t need to be big to cause problems.
The Lorentz force, which is the force produced when a current-carrying wire is put in a magnetic field, is the basis for how voice coil actuators operate. The magnetic field is produced by permanent magnets in the case of a voice coil actuator, and the conductor is a coil of wire.
PPS resin, also known as polyphenylene sulphide, is a crystalline heat-resistant polymer with a straightforward chemical structure consisting of benzene and sulphur.
The global Hard disk actuator coil sealing PPS resin market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
In the electrical / electronic sector, PPS is also used to manufacture a range of articles including bobbins and connectors, hard disk drives, electronic housings, sockets, switches and relays. The key trend influencing PPS growth in electrical / electronic applications is substitution of other lower temperature polymers.
A plastic overmold of the coil part is created, together with the inner plastic sleeve. To do this, a coil wrapped around an E-block and coil bobbin is placed in a mould.
Ports are then filled with a suitable plastic, such as polyphenylene sulphide (“PPS”) filled with 40% glass, to make an integral plastic inner sleeve and plastic overmold. As a result, the moulding ports are used to link the plastic inner sleeve and plastic overmold.
