Four-hole Coaxial ±0.003mm Semiconductor Packaging Dedicated Positioning Base With Zero Magnetic Interference
When precision injection molding encounters challenges with magnetic interference and positioning accuracy, the four-hole injection molding seat, precisely manufactured from WC-Ni non-magnetic carbide, completely resolves the pain points of magnetic attraction and thermal deformation associated with traditional mold parts through its overall non-magnetic structure combined with four-hole coaxial precision machining technology. This enables superior performance in semiconductor packaging and precision medical device injection molding, with zero magnetic interference, high-precision positioning, and an extremely long life.
