Outsourcing vs. In-House Machinery – What Pays Off for Manufacturing Companies?
Introduction
Many manufacturing entrepreneurs ask themselves: “Laser cutting – outsource it or buy a machine?” In an era of increasing competitiveness and rapid technological progress, the decision to outsource component production versus invest in in-house machinery is a strategic dilemma. In this article, we analyse both approaches – contracting out sheet metal processing to specialist companies versus investing in your own machinery – in terms of costs, quality, work organisation and current market trends. The aim is to find an answer to what pays off more for manufacturing companies in the metal industry in various business scenarios.
Investment Costs vs. External Service Costs
High Financial Entry Threshold
Purchasing modern CNC machines (e.g. laser cutters, press brakes) involves enormous expenditure. A good-quality metal laser cutter costs in the order of several hundred thousand zlotys – often PLN 500,000 or more for a single machine. Added to this are the costs of accessories, installation and technical infrastructure (dust extraction systems, cooling, software). Maintaining such equipment generates ongoing expenditure on servicing and updates. Outsourcing avoids these capital expenditures – we use the supplier’s machines, paying only for the service performed. This means we do not freeze capital in fixed assets and can allocate resources to other business needs.
Depreciation and Utilisation
Even if a company invests in its own CNC laser, it must ensure adequate workload to achieve a return on investment. If machines cannot be fully utilised, long periods of idle time occur. Outsourcing solves this problem, as the service provider can serve multiple clients on one machine, maximising its productive capacity. As a result, unit costs for the client are lower than if the machine were operating intermittently for a single company only.
Operational Costs and Rate Comparison
Laser cutting requires electricity, technical gases (e.g. nitrogen, oxygen) and consumes consumable components (nozzles, lenses, covers). Average operating costs of cutting on a modern fibre laser are estimated at approximately PLN 30–70 per hour of operation. When owning a machine, periodic servicing, spare parts and repair costs must also be factored in. Industry forums indicate that market rates for laser cutting services in Poland range from approximately PLN 300 to 600 per machine hour, depending on the complexity of the order. If an in-house machine were idle for most of the time (e.g. utilisation below 50%), the effective unit cost per hour could easily exceed these outsourcing rates. In the service model, we pay only for the actual cutting time of our components, without worrying about equipment standing unused.
Labour Costs, Access to Know-How and Other Barriers
Setting up sheet metal processing in-house involves not only purchasing machines but also providing qualified personnel. Operating a CNC laser or machining centre requires at minimum one experienced production worker, a CNC operator-programmer and a process engineer. Hiring such specialists generates high labour costs. Outsourcing eliminates a large part of these problems, as the service provider ensures staff with the appropriate competencies. In practice, we commission work to a company that employs its own operators, technologists and quality inspectors – we do not directly bear the cost of their work beyond the agreed service price.
By choosing to work with an experienced external partner, we effectively purchase access to expert knowledge and modern technologies. Specialist metal processing companies carry out a wide variety of projects on a daily basis, giving them broad experience with which they can offer technical advice. When contracting work to them, we can count on process optimisation – for example in terms of material selection, cutting parameters or operation sequence – which will translate into a better end result.
Quality of Execution and Control Over the Product
Companies specialising in metal processing services invest in the latest machines, as this is the core of their business. By outsourcing, we gain access to such a modern machinery fleet without the need to purchase it ourselves. If a newer technology appears in a few years’ time, the subcontractor will likely update its machinery while we – with our own machine – would be left with potentially outdated equipment. Outsourcing thus transfers the risk of technological obsolescence to the service provider.
A good external company places great emphasis on quality control of its products. It has appropriate measuring systems, component checking procedures and certificates (e.g. ISO). On the other hand, owning a machine theoretically gives full control over the process – we select the parameters, supervise every stage and can make modifications as we go. This flexibility is useful in product development work or prototyping.
Flexibility and Scalability of Production
One of the greatest advantages of outsourcing is flexibility in responding to fluctuating orders. When demand for our products grows, we can easily increase the number of outsourced components – simply by ordering additional batches from the external company. When orders decline, we simply commission less – we do not need to worry about our own machines standing idle and generating costs. This scalability is particularly valuable for companies that operate on a project or seasonal basis, with uneven production workloads.
When a manufacturing company is growing dynamically, demand for components naturally increases. We are then faced with a choice: expand the in-house machinery fleet (purchase another laser, press, hire new staff) or extend cooperation with subcontractors. In-house expansion means again incurring high investment costs and increasing fixed costs. Outsourcing, on the other hand, enables scaling without major capital expenditure – we can increase the volume of orders with existing or new partners without capital investment.
When Does In-House Machinery Pay Off?
Despite the many advantages of outsourcing, there are scenarios in which investing in in-house machinery may be justified or even necessary. Above all, this applies to companies with very large and constant production volumes. If a plant needs to process enormous amounts of material every day in a repeatable way (e.g. producing identical components in long series), the unit cost of outsourcing could be higher than in-house costs after the investment is repaid. Own machinery may also be indispensable when reaction time is critical – if orders appear suddenly and must be fulfilled literally from one day to the next, having a key machine in-house shortens the supply chain. A practical hybrid approach is to maintain a minimum number of essential machines in-house (e.g. for prototypes or the most critical operations) and cover remaining demand through a network of trusted subcontractors.
Current Industry Trends
The contemporary industrial sector is increasingly using outsourcing of specialist processes. The combination of automation (CNC) and outsourcing contributes to enormous productivity and reduction in production costs. Even large corporations that could afford extensive in-house facilities choose the cooperation model with a network of subcontractors. The reason is cost optimisation: modern CNC metal processing machines are so efficient that maintaining them exclusively for one product line would result in unused production capacity. Another trend is the drive towards a lean and agile enterprise model – companies focus on their core specialisation and seek to entrust other processes to partners. Digitalisation (Industry 4.0) means that remote collaboration with subcontractors is easier. CAD/CAM designs are transmitted electronically, order status can be tracked online, and system integration (e.g. ERP) between the client and contractor accelerates information flow. This reduces barriers to collaboration and makes outsourcing an even more attractive business model.
Summary
What pays off more – outsourcing or in-house machinery? The answer depends on the individual situation of the company, but for medium and large industrial companies with a variable order portfolio, outsourcing is often more advantageous. Outsourcing CNC metal processing tends to be most cost-effective when it allows us to avoid multi-million investments in equipment, while benefiting from the experience and production capacity of a specialised partner. External services allow fixed costs to be reduced, production flexibility to be increased and focus to be maintained on core business competencies.
For most manufacturing companies, the key is to find the golden mean. A commonly practised approach is to maintain a minimum necessary number of machines in-house (e.g. for prototypes or the most critical operations) while covering the rest of demand through a network of trusted partners. This hybrid model combines the advantages of both worlds – control where it is crucial, and savings and flexibility where economics of scale apply. When considering outsourcing of sheet metal processing, choose an experienced partner with a modern machinery fleet and established quality processes. Cooperation with an expert company will ensure not only the timely completion of components at a good price, but also professional support and the assurance that production is in good hands.
