Outsource vs in-house manufacturing: how to decide

The honest comparison

In-house looks cheaper because invoices disappear - but the machine hourly cost (depreciation, maintenance, energy, floor space) plus operator time and failure risk still accrue. Compare supplier quotes against your true all-in internal cost, not against material price.

When in-house wins

Steady utilization above ~40%, IP sensitivity, iteration speed needs, or capability as your actual product. A machine you keep busy pays for itself; a machine bought for one project rarely does.

When outsourcing wins

Spiky demand, capabilities you touch monthly not daily (5-axis, plating, molding), and anything where a specialist's scrap rate beats your learning curve. Outsourcing converts fixed cost into variable cost - valuable when demand is uncertain.
