Supply Chain

Vertically Integrated — Plus a 30-Year Partner Network

We operate our own factories for core magnet production and magnetization. For anything outside our immediate capabilities, our decades-long relationships with dozens of specialist partners mean we can manufacture to your every need — under one point of contact.

Our Promise

One Contact, Full Scope

You won't need to juggle multiple vendors. Mainrich coordinates everything — quoting, tooling, QA, and logistics — regardless of which facility produces the part.

How the Network Works

In-House Production

NdFeB sintering, pressing, machining, coating, and multi-pole magnetization happen in our own ISO-certified facilities.

Partner Specialties

When a project calls for SmCo, ferrite, bonded magnets, or unusual assembly, we route to long-standing partners who specialize in that capability.

Unified QA

Every order — whether from our factory or a partner — goes through the same incoming inspection and documentation standards before shipment.

Single Invoice, Single Point

Coordinated quoting and consolidated shipments simplify your procurement — no matter how many facilities are involved behind the scenes.

Beyond Magnets — Extended Capabilities

Through our partner network we support adjacent components that often ship alongside magnet assemblies.

Motor Laminations

Stator and rotor stacks from partner stamping facilities.

Injection Molding

Overmolded rotors, housings, and bonded magnet shapes.

Precision Machining

Shafts, brackets, and custom fixtures.

Assemblies & Kitting

Sub-assemblies delivered ready-to-install.
