01
Count opportunity cost
Designing in-house uses engineering and production time for research, modelling, bills of material, procurement, fabrication, testing and debugging. It also requires build and test space that could otherwise support the company's core product.
02
Expose the hidden work
A realistic comparison includes purchase-order administration, receiving, component storage, design revisions, installation changes and the learning curve behind a one-off machine. Ongoing ownership adds drawings, manuals, maintenance procedures, training and an accurate spare-parts list.
03
Use the same decision criteria
Buying can provide established designs and application experience; making can suit teams with conveyor engineering as a genuine core capability or an unusual requirement that cannot be sourced. Compare both options against identical requirements for performance, safety, documentation, maintainability and lifecycle cost.
- Who owns the design after staff changes?
- How will repeat units remain consistent?
- What is the recovery plan for an obsolete component?
Field checklist
Evaluate embedded conveyors as lifecycle components
For an OEM, buying a proven embedded conveyor can reduce the engineering, sourcing, testing and documentation work carried by every machine revision. The comparison should include repeat-unit consistency, spare-parts ownership and the time needed to validate guarding, controls and belt behaviour—not only the first bill of materials.
- Separate one-time design work from cost per repeat machine
- Include drawings, manuals and change control
- Account for testing space and commissioning time
- Plan replacement parts across the machine's service life
