At TOS – Technical Outsource Solutions, we support companies in developing and producing high-quality deep-drawn parts. Deep drawing is the technology for creating thin-walled, seamless products with complex shapes and high dimensional accuracy.
We advise on material selection, tolerances, and post-processing, and support customers from design to series production. Thanks to our international network of specialized partners, we offer competitive prices, short delivery times, and flexible production runs. With TOS, you choose a single partner who manages the entire deep drawing process – from engineering to post-processing and finishing.
Deep drawing is a forming technique in which a flat metal sheet is drawn in a die to create a three-dimensional shape. The process is often used for thin-walled, hollow products such as cups, casings, technical housings, and components for automotive, electronics, and mechanical engineering.
The major advantage of deep drawing is that products are seamless and strong, without welds or weak points. This results in high dimensional stability, even with thin walls. Thanks to modern molds, complex geometries can also be produced with tight tolerances.
At TOS , we guide customers in optimizing their designs for the deep drawing process (Design for Manufacturing). After forming, parts can be further refined with CNC machining processes such as drilling, milling, or tapping. For protection and appearance, we offer various surface treatments such as anodizing , powder coating , e-coating , or galvanizing .
We deliver complete solutions: from simple prototypes to large-scale series production. With TOS, you choose a reliable partner that combines quality , speed, and efficiency.
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.
Deep drawing is often used with steel and stainless steel due to their strength and durability. Stainless steel is also corrosion-resistant and widely used in the food, chemical, and medical industries. Aluminum is a popular alternative when low weight and good formability are important. Copper and brass can also be used for decorative or technical products.
At TOS, we recommend the most suitable material for each project, tailored to product properties, machinability, and desired surface finish.

We start with a comprehensive intake interview , discussing the application, volumes, budget, and delivery times. This gives us a complete picture of your needs and the functional requirements of the product to be deep-drawn.
Our engineers analyze the design and provide Design for Manufacturing (DFM) advice. This includes considerations such as wall thickness, draw ratios, and draft angles. We also advise on the most suitable alloy (steel, aluminum, or stainless steel) to ensure the product is technically and economically optimized .
Based on your design and volumes, you’ll receive a transparent quote. This quote clearly details mold costs and unit prices. You’ll also receive an estimated delivery time and a clear schedule , so you know exactly what to expect in advance.
A high-quality die is the key to successful deep drawing. Our specialists develop and produce the drawing die, taking into account tolerances, material behavior, and production stability. This forms the basis for consistent series production. Often before the deep drawing dies are started, we print 3D models and offer them for inspection.
Before we start series production, a First Article Inspection (FAI) is performed. This involves producing the first deep-drawn parts, which are carefully assessed for dimensions, surface quality, and material performance. Any improvements are addressed immediately.
If desired, we perform additional CNC post-processing , such as milling, drilling, or tapping. We can also apply surface treatments such as anodizing , chrome plating , powder coating, e-coating , or galvanizing to our products for protection or an aesthetic finish.
All products are thoroughly inspected according to international quality standards . We provide measurement reports, material certificates, and additional documentation upon request. This ensures transparency and traceability.
Finally, we can assemble components into semi-finished products or modules, package them according to customer specifications, and prepare them for export. We also handle logistics , inventory management, and delivery, so you have a single point of contact for the entire process.
