Capabilities

Comprehensive Metal Spinning Expertise

With more than 70 years of know-how and continuous investment in technology, TMS – Technical Metal Spinning delivers one of the most versatile and advanced production capabilities in the industry. From prototypes to large-scale production, our machine park enables precise, cost-efficient, and repeatable manufacturing.

Unlike stamping, which is only cost-effective in very high volumes, metal spinning offers unmatched flexibility for medium to large diameters, complex shapes, and special alloys. Especially above Ø500 mm, spinning becomes the most economical and often the only viable solution.

Quality & Certification

All our processes comply with ISO 9001 Quality Management standards, ensuring consistent quality and full traceability for our customers.

Our Equipment and Facilities

We operate across the full range of spinning technologies:

• Manual Spinning Lathes – Ideal for R&D and prototypes, with a capacity up to Ø40 cm.
• Hydraulic Template-Controlled Lathes – Traditional hydraulic spinning lathes equipped with form templates, used for producing medium-size parts with consistent geometry. Suitable for aluminium and thin-gauge mild steel.
• Automatic & CNC Spinning Lathes – Siemens Sinumerik 802D SL Pro and 808D controlled systems, handling diameters up to Ø1200 mm, with 6 mm Aluminium (T0), 5 mm Mild Steel, or 3 mm Stainless Steel (AISI 310S).
• ST-1000 BORA (CNC Spinning Lathe) – Equipped with Siemens 802DSL controller, designed for up to Ø1000 mm diameters and capable of forming 6 mm Aluminium (T0), 2 mm Mild Steel, and 1.5 mm Stainless Steel.
• Special Projects & Retrofits – Custom conversions and in-house modernizations such as ST1200 (3-axis CNC configuration), ST-1000 BORA modernization, and APED-351 upgrade, integrating Siemens Sinumerik controls, servo systems, and customized tooling solutions.

Hot Spinning Capabilities

Certain alloys require elevated temperatures to achieve the necessary ductility and avoid micro-cracks. At TMS, we specialize in hot spinning, particularly for stainless steels like AISI 310S.

• Preheating Range: 400–700 °C (optimized to 440–460 °C for AISI 310S)
• Special Tooling: Heat-resistant forming wheels (Al-Bronze, large CR radii) to minimize stress
• Pass Strategy: Multi-wave forming for gradual deformation, reduced thinning, and controlled spring-back
• Lubrication & Cooling: Graphite-based lubricants and controlled cooling extend tool life and protect surfaces

Advantages of Hot Spinning:

• Enables forming of high-strength alloys not possible cold
• Reduces risk of cracks and fractures
• Maintains dimensional accuracy under heat
• Extends capacity to large diameters (up to Ø1200 mm) and thicker walls
• Improves ductility and material flow

Applications: Aerospace heat shields, ventilation & exhaust systems, industrial burners, combustion chambers, agricultural and food industry equipment.

Material Range

In addition to aluminium and stainless steel, we also process copper, brass, and heat-resistant alloys upon request.

Advantages of Metal Spinning with TMS

• Rapid prototyping with short lead times
• Optimized design solutions to reduce production costs
• Lower tooling investment compared to stamping
• Ability to form hard-to-process alloys (AISI 310S, Inconel, etc.)
• Tight tolerances up to ±0.05 mm
• Flexibility in batch sizes – from single parts to series production
• In-house secondary operations: trimming, cutting, welding, calibration, polishing
• Stronger, more ductile parts with lower risk of cracking

Core Operations

Depending on project needs, we apply a wide range of forming and finishing processes:

• Preforms (cylinders, cones, shells)
• Hot Spinning (temperature-assisted forming)
• Conventional Spinning (multi-pass forming)
• Necking-in – reducing the diameter of tubular or cylindrical parts
• Trimming – precise cutting of excess material
• Calibration – dimensional fine-tuning
• Parting-off – separating finished part from the blank
• Edge Treatments – trimming, curling, beading, hemming, profiling
• Finishing – polishing, calibration, robotic MIG/MAG welding, laser cutting

Industry Applications

Our components are widely used in ventilation, energy, food processing, lighting, and transportation industries.

Basic Operations Of Metal Spinning

In forming a part by Metal spinning, a combination of processes may be utilized to complete a part. These processes include: Preforms, Conventional Spinning, Shear and Flow forming, Edge treatment (Trimming, Curling, Profiling, Planishing, Expanding, Necking-in, Parting-off) as well as secondary operations.

Preforms

A preform is a partially formed part that is used to increase the efficiency of the next forming process. Preforms may be in the shape of a cylinder, shells, cones and more. These preforms can be achieved through spinning or other forming operations such as drawing.

Conventional Metal Spinning

The Metal Spinning process usually involves a series of passes to complete the formed part. During each pass the metal is stretched thus thinning out the material. This thin-out characteristic is typical of the conventional metal spinning process. If necessary, thin out can be minimized.

Shear and Flow Forming

Shear and Flow forming is a variation of Conventional Metal Spinning. Shear forming refers to the formation of a part in just one pass. This process allows for an accurate prediction of finished material thickness. Shear forming is typically associated with conical and cylindrical shapes.

Edge Treatment

The edges of a part can be finished in many ways. Parts can be trimmed for a straight edge, hemmed for a folded edge or beaded for a rolled or curled edge. These edge treatments can be performed in a spinning lathe or on a separate machine that specializes in edge treatment.
