360° OEM Assembly Solutions — 8 Suppliers Consolidated to 1

A global OEM was managing 8 separate suppliers for the components of a single sub-assembly. 8 purchase orders. 8 delivery schedules. 8 quality checks on receipt. And when something was wrong at assembly, 8 suppliers pointing at each other. Amsol took over the complete sub-assembly — everything under one PO.

Key Outcome

The OEM's procurement team went from managing a fragmented multi-supplier programme to placing a single purchase order for a complete, inspected, assembly-ready sub-unit.

The Situation

The Real Cost of a Multi-Supplier Sub-Assembly Programme

The hidden cost of managing 8 suppliers for one product line is rarely calculated. Every incoming delivery needs a quality check. Every mismatch between component tolerances from different suppliers needs an investigation. Every late delivery from one of 8 suppliers stops the assembly line.

And when the assembly fails — when the machined shaft does not fit the bore of the casting because two suppliers interpreted the same drawing differently — there is no single partner to call. Just 8 suppliers, each explaining why it was not their fault.

The Problem

What the OEM was facing.

✕8 purchase orders for 8 components in one sub-assembly — management overhead

✕8 incoming quality inspections on receipt — each requiring time and resource

✕Split tolerance accountability: no single partner owns the interface between components

✕Delivery risk multiplied ×8 — one late supplier stops the entire assembly

✕When assembly fails — 8 suppliers available, zero accountability

Amsol's Approach

The engineering-led solution.

✓Amsol took on the complete sub-assembly programme across all 8 component types

✓All components sourced or manufactured through Amsol's 13-process network

✓Amsol owns all inter-component tolerance interfaces — fit guaranteed before despatch

✓One PO, one delivery, one quality check — complete assembled unit inspected at Amsol

✓One point of accountability — one call to Amsol covers any quality or delivery issue

What Amsol Did

What the Sub-Assembly Contained — 7 Components, 1 Amsol PO

The sub-assembly required components across five different manufacturing processes. Before Amsol: 8 suppliers, 8 POs, 8 deliveries. After Amsol: 1 supplier, 1 PO, 1 delivery.

Component 01

Cast Iron Housing

Shell mould casting + CNC machining — bearing interfaces to H7

Component 02

Precision Ground Shaft

EN24 steel · CNC turned + cylindrically ground to h6

Component 03

Forged Structural Bracket

Closed die forging + CNC machining — structural load interfaces

Component 04

Injection Moulded Cover

PA66+GF30 · precision tooled · assembly fit validated at Amsol

Component 05–07

Bearing Housing + Fastener Kit + Final Assembly

Shell mould + CMM bore · sourced and kitted · assembled, inspected, labelled to OEM standard

Result

1 PO. 1 Delivery. 0 Assembly Issues.

Complete sub-assembly inspected at Amsol before despatch — ready to install on arrival

The most expensive thing in a multi-supplier sub-assembly programme is not the components. It is the management overhead, the split quality accountability, and the production line stoppage when two suppliers disagree on whose tolerance was wrong. Amsol removes all three.
