Inside MOARCONN's In-House Molding & Stamping: How We Keep Lead Time to 25 Days

Why outsourcing the process creates delays

When a connector project slips, it is rarely the design that fails. It is the wait: waiting for the mold shop, waiting for the stamping vendor, waiting for the molding supplier, and then reconciling the tolerances between three different factories. Every hand-off adds days and risk. MOARCONN removes those hand-offs by owning the mold, the stamping and the molding under one roof.

A mold shop that controls precision in-house

The card socket housing starts in MOARCONN's own mold facility, equipped with precision grinding, Sodick EDM and CNC engraving machines. Mold accuracy is held to plus or minus 0.002 millimetres, which is what makes the later molding consistent enough for high-speed, high-cycle card sockets.

20 automated stamping presses for consistent terminals

Terminals are the contact heart of the connector. MOARCONN runs 20 fully automated high-precision stamping presses in-house, so terminal geometry, plating and contact force stay consistent from the first part to the millionth.

40 injection molding machines for precision housings

The housing line runs 40 high-precision injection molding machines, a mix of horizontal Fanuc and Nissei presses and vertical machines from 15 to 110 tons. Injection-molded parts are held to 0.01 millimetre accuracy, which is what lets Nano SIM sockets reach 1.1 millimetres in height and still seat the card cleanly.

The result - 25-day development and 7-day sampling

Because the mold, the stamping and the molding live in one factory, a new card connector goes from drawing to samples in 7 days and to qualified production in a 25-day development cycle, with zero MOQ and free samples. That is the difference vertical integration makes.
