Imagine a world without chips: no smartphones, no laptops, no digital cameras. That is why shaping performs a critical function in semiconductor manufacturing. The rolled rings manufacturer uses precision and difficult forgings to create additives that are essential for digital devices to work effectively.

Semiconductors are materials that conduct electricity better than insulators like ceramics, but not as well as conductors like metals. They can be compounds like gallium arsenide or pure elements like germanium or silicon. The function of semiconductor is to control and manage the flow of electric current in electronic equipment and devices. From smartphones to home appliances, cars, transportation, and medical devices, semiconductors power almost all the technology that we rely on today
