Outsourcing metal products means a company outsources (part of) its production to external specialists. Companies do this to save costs, increase capacity, or gain access to technologies not available in-house. In metalworking—think machining, welding, casting, forging, and extrusion—outsourcing often offers significant benefits because specialized factories produce more efficiently and cost-effectively.
Many companies choose Poland for high-quality CNC machining, construction work, and welded assemblies, thanks to the fast delivery times and short logistics lines. China, on the other hand, is chosen for techniques such as sand casting, high-pressure casting, lost-wax casting, forging, extrusion, and mass production. Moreover, the mold and die costs are much lower, making large series attractive.
TOS manages outsourcing according to a standard procedure, providing technical advice, design optimization, and smooth communication between client and supplier. We also manage the entire supply chain, from factory to final destination, so clients have a single point of contact and are never faced with surprises.
Successful outsourcing starts with a clear technical foundation: 3D models, working drawings, tolerances, and material information. TOS assesses this data and determines whether the design can be produced more intelligently, cheaply, or efficiently. This is called product optimization and prevents high costs or unnecessary rework.
Next, we select the right factory for the product type. For frames, welded structures, cutting, bending, and CNC machining, we almost always choose Poland. For castings, injection molding, forging, extrusions, and projects requiring mold costs, China is the most logical choice. This is followed by a cost estimate, quote, and a clear schedule.
During production, we perform quality controls according to our established procedures. In Poland, this is often done directly on-site; in China, we monitor this through photographic reports, interim measurements, or external inspections (such as SGS).
Next comes logistics:
The entire supply chain – production, packaging, documentation, transport and customs clearance – is managed by TOS so that customers are completely unburdened.
During this conversation we will briefly explain what we can do for you and answer your questions.
Based on your product and requirements, we request prices and delivery times from various suppliers.
We will then prepare a clear quote. Prices are quoted based on your terms and conditions.
Once you have approved our proposal, we will start making a prototype.
After approval of the prototype, the assignment will begin.
Quality assurance is a crucial part of outsourcing. That is why TOS follows a structured workflow with clear process steps: technical preparation, prototyping, sample inspection, production control, and final inspection. This structure ensures that components meet requirements for dimensions, material, finish, and assembly-ready delivery.
When outsourcing to Poland, communication and coordination are generally very smooth due to geographical proximity and short lines of contact. Adjustments to structural work or CNC components can be quickly discussed and scheduled, making the process efficient without unnecessary delays. Large constructions and welded assemblies are often impractical to ship by container, making Poland the logical and reliable choice for such projects.
China, on the other hand, offers enormous technical diversity and is ideal for products requiring molds, extrusions, or casting. Costs are lower, capacity is higher, and quality has significantly improved over the past ten years. Through our controlled supply chain, risks are minimized and lead times remain predictable, despite the greater distance.
By combining outsourcing with a well-organized supply chain and a clear workflow, companies can maximize the benefits of international production—without having to manage complex factory contacts themselves.
