ZHENHUA Injection Molding Machine for Keyboard Key Producing

Short Description:

3.The Application of Injection Molding Machine in Keyboard

Injection molding machines can produce multiple parts of keyboards, some of the main parts include:

Keycap: is the covering of the keys on the keyboard.

Key shaft: The keys of the keyboard are connected to the circuit board of the keyboard through the key shaft.

Key connectors: The keys in the keyboard usually need to be connected to the keyboard circuit board through connectors.

Structural Stand: The keyboard’s structural stand is usually made of plastic

Common materials that can produce keyboard parts include but are not limited to: ABS (acrylonitrile-butadiene-styrene copolymer),PC (polycarbonate),PBT (polybutylene terephthalate)

Advantages of a standard injection molding machine

Standard injection molding machine’s advantages:

(1)Strong production capacity: by adjusting the injection speed, pressure, temperature and other parameters, you can quickly inject a large number of products, improve production efficiency.

(2)Relatively low cost: Compared to new technology injection molding machines, the cost of standard injection molding machines is usually lower.
