Cold-pressing process for PIM‑integrated inductors

PIM monolithic micro‑inductors are already at the forefront of the industry, meeting the demands of the 5G era. We offer a comprehensive, end-to-end solution for PIM monolithic inductors—unconstrained by material, technology, or equipment limitations.

Cold pressing is the first major process station in PIM’s ultra‑miniature integrated molding of inductors.

1. Powder delivery

Evenly dispense a fixed amount of powder into the mold cavity.

2. Molding

Press the uniform powder into a shaped compact,

A structure with a certain degree of strength

3. Demolding and Material Removal

Detach the PIM monolithic inductor from the mold without damage.

It comes out and is fed into the receiving tray.

A method to ensure damage-free fabrication of PIM micro‑molded inductors: Align the middle die, the first punch, and the second punch at the same level. The powder feeder speed should not be too high.

The equipment is independently developed and can be customized to accommodate different materials and product performance requirements. It features cam-driven operation, ensuring dimensional stability with a tolerance of ±0.02 mm.

Life Cycle Assessment (LCA) is a standardized, systematic, and quantitative methodology for evaluating the resource and environmental efficiency of a product throughout its entire life cycle. By tracing the production and consumption stages upstream and downstream, LCA helps manufacturers identify the specific phases where environmental impacts arise and facilitates the mitigation of their transfer across different life-cycle stages and among various types of environmental effects. Many industries, both domestically and internationally, have undertaken product LCA assessments to support benchmarking and continuous improvement within firms, foster external communication, and provide evidence‑based input for policy formulation.
