A number of Chinese Taiwan Metal Injection Molded notebook and
IT component suppliers have begun taking advantage of the
opportunities provided for MIM producers in the electric vehicle
industry, according to a report by Taiwan-based newspaper
A key opportunity for MIM producers in the
electric vehicle market is the manufacture of Insulated-Gate
Bipolar Transistor (IGBT) cold plates by
Metal Injection Molding (MIM).
These devices are typically used in high-end liquid cooling
systems, particularly those with limited thermal dissipation
space, such as Electric Vehicle/Hybrid Electric Vehicle power
These systems generally have a compact structure with little
thermal dissipation space and thus have difficulties dissipating
heat generated. MIM technology can be used to achieve a complex
geometric design that provides both high thermal performance and
low pressure drop, and also enables the production of
thin-walled metal components for better heat dissipation.
MIM faces some competition from forging in this arena, with
Jentech, Taoyuan, Chinese Taiwan, reporting the certification of
its forged IGBT power modules in the first quarter. However, MIM
offers significant advantages over forging for the production of
small, complex electrical parts, the demand for which is
expected to grow with the rise in electric vehicle manufacture.
Tesla has reportedly been working with Taiwan’s electronics
manufacturers for products such as motherboards. According to
Digitimes, Taipei-based Pegatron Technology is rumoured
to have landed central computer motherboard orders from Tesla
for its Tesla Model 3, but Pegatron declined to comment on its
clients or orders.
