VIEW PRODUCTSIs It Better to Manufacture Screw Flights In-House or Outsource Production?
Nov 13,2026
The first question is whether order volume is stable enough to support internal production. A workshop receiving frequent repeat orders may be able to keep a forming machine in regular use. A company handling occasional replacement flights or one-off custom designs may find that the machine sits idle for long periods. In the latter case, the supplier’s ability to serve multiple customers may provide a cost advantage.
Demand should be measured by product mix, not only total pieces. Different outside diameters, inside diameters, pitches, plate thicknesses and material grades may require different tooling or setup time. A high annual quantity spread across many uncommon sizes may not produce the same utilization benefit as repeat orders in a standard range.
Assess the true cost of internal production
A fair in-house calculation includes the machine, financing or depreciation, tooling, installation, floor space, power, labour, supervision, training, maintenance, spare parts, inspection and scrap. It should also include process-development time and the opportunity cost of capital that could be used for sales, inventory or other production bottlenecks.
Do not assume that a lower theoretical unit cost means a lower business cost. If the machine is underutilized, fixed expenses are spread across fewer flights. If skilled operators are unavailable, production may depend on a small number of people. If the company must develop the process from the beginning, the initial quality and productivity curve should be considered.
Understand the benefits and risks of outsourcing
An external supplier may already have forming equipment, tooling and experienced operators. This can help the buyer access a specialized process without carrying the full fixed cost. Outsourcing may be suitable for low-volume jobs, irregular demand, special sizes, temporary capacity shortages or early-stage production.
The buyer should evaluate the supplier’s ability to meet the drawing, material and inspection requirements. Key risks include long lead times, inconsistent batches, freight damage, supplier capacity constraints, price changes and limited alternative sources. Use a clear technical specification, sample approval and an agreed nonconformance process to manage these risks.
Define the boundary between internal and external operations
A sourcing decision does not need to cover the whole screw conveyor. A company may buy formed flights but retain shaft preparation, fit-up, welding and final inspection. It may also outsource overflow orders while producing standard products internally. The assembly interface must be specified clearly, including shaft or tube dimensions, flight inside diameter, pitch, orientation and required inspection.
For screw feeder or shaft-related assemblies, the Plug Screw Feeder Shaft is an adjacent product reference. It should be evaluated as a separate component and not assumed to match every flight design.
Use a structured make-or-buy review
Compare the total landed supplier cost with the fully loaded internal cost. The outsourced figure should include quotation, transport, customs where relevant, incoming inspection, inventory and supplier-management effort. The internal figure should include avoidable fixed cost and variable cost per part. A break-even volume estimate can indicate when in-house production may become competitive, but it should be tested against several demand scenarios.
Non-financial factors also matter. Consider quality-critical dimensions, delivery response, confidentiality, supplier dependency, process know-how and the ability to make engineering changes. Keep critical drawings and acceptance criteria under controlled revision, whether the part is produced internally or externally.
A staged strategy can reduce investment risk
For many businesses, the most practical approach is to outsource at the beginning, collect actual data on demand and quality, and review the economics after several production cycles. If recurring volume is established, the company can consider a suitable Spiral Blade Forming Machine and bring selected flight sizes in-house. External suppliers can remain useful for peak demand and special jobs.
Conclusion
The right sourcing model depends on stable demand, total cost, technical capability and strategic importance. In-house production is not automatically cheaper, and outsourcing is not automatically lower risk. A structured review based on real drawings, actual order history and comparable cost data will provide a stronger decision than comparing machine price with supplier piece price.
