What is assembling and what possibilities does TOS offer?

Assembly is the process of joining individual parts together to form a complete product or semi-finished product. This can range from simple assemblies with a few components to complex modules involving multiple materials and production techniques.

Because TOS has a wide range of in-house processing capabilities through our international network, we can seamlessly combine these processes. Consider, for example, parts produced via extrusion , high-pressure die casting , sand casting, gravity die casting , or lost-wax casting . We also integrate processes such as CNC machining , metal cutting , stamping , forging , deep drawing , and metal welding into a single assembly line.

After production, components can be surface-treated with powder coating , anodizing, or galvanizing . We then handle the complete assembly into a finished product, including packaging and delivery.

With this integrated approach, you benefit from shorter lead times, lower logistics costs, and guaranteed quality. TOS is your assembly partner: a single point of contact for the entire process, from component production to finished product.

We will then prepare a clear quote. Prices are quoted based on your terms and conditions.

Prototype and approval

Once you have approved our proposal, we will start making a prototype.

Quality control and delivery

After approval of the prototype, the assignment will begin.

Advantages and Disadvantages of Assembling

How we work on an assembly project

At TOS, we offer complete solutions for assembling components, modules, and finished products. We combine technical expertise with efficient production methods, allowing us to assemble small and large series with consistent quality. From initial design to final delivery, we handle the entire process, including production, finishing, and logistics.

We start every project with a comprehensive intake. During this meeting, we discuss the type of assembly, desired volumes, budget, and lead time. This gives us a clear understanding of your needs and allows us to choose the most efficient approach for assembling your product.
Our engineers analyze the design and provide Design for Manufacturing (DFM) advice. We determine the most suitable assembly method, such as screwing, welding, bonding, or mechanical joining. We also consider the production techniques needed to optimally prepare the components for assembly, ensuring efficiency and quality.
After the initial consultation, you’ll receive a transparent quote with a clear cost breakdown. We’ll specify both assembly costs and any component production costs. We’ll also provide a realistic schedule with an expected lead time, giving you complete insight into price, delivery time, and the process flow.
Reliable components are essential for a successful assembly project. TOS produces components using a variety of techniques, including extrusion , casting, CNC machining , laser cutting , stamping , welding , or forging . Our extensive production capabilities allow us to supply virtually any type of component, precisely tailored to customer specifications and requirements.
Before serial production begins, we perform a First Article Inspection (FAI). This involves assembling the first products to ensure all components fit together properly and the assembly method functions correctly. This allows for timely adjustments, ensuring a flawless final product.
After the trial assembly, we incorporate the feedback and finalize the specifications in a design freeze. This ensures that no further changes are made during serial assembly, making the production process predictable and efficient, with minimal risk and a guaranteed quality outcome.
Once all specifications are confirmed, we begin serial production. During serial assembly, we work according to the drawings, process standards, and quality standards. Thanks to our experience and strict process control, we can produce both small series and large-scale assemblies with consistent repeatability and high production speeds.

In addition to assembly, we also perform additional processes to fully finish the product. These include welding, drilling, bonding, and specific surface treatments such as powder coating , hot-dip galvanizing , or chrome plating . This ensures that every product is not only technically sound but also durable and aesthetically pleasing.

Every assembly is subjected to extensive quality controls . We perform both visual and dimensional inspections and verify functional properties. Upon request, we can provide reports, measurement certificates, and material declarations, ensuring complete transparency and traceability throughout the entire assembly process.

Finally, we ensure that the assembled products are packaged safely and according to customer specifications, are ready for export, and are delivered on time. We also support you with logistics solutions , inventory management, and just-in-time delivery. Our aftercare focuses on continuous improvement, so that future assembly projects run even more efficiently.
