Closed die forging
of aluminium and copper.

Custom forgings to drawing. We design and make the dies in our own toolroom and forge on screw and crank presses.

Toolroom and engineering

A part is not born on the press, but at the engineer's desk.

Our engineers bring process and production know how: they know how metal flows in the die, where to add draft, how to minimise flash and what saves time in machining. Material flow is verified in FORGE simulation before any tool is cut.

Our toolroom then builds the die on MAS and Röders machining centres. Customers deal with one partner and changes take days, not weeks.

Toolroom and engineering

Before we forge

Preparation decides cost and quality. That is why we do it ourselves.

01

Drawing and brief

We review drawing, material and batch size and suggest changes that cut forging and machining cost.

02

Design and simulation

Engineers design the forging and the die and verify material flow in FORGE.

03

Tool making

Our toolroom builds the die and trimming tool, followed by sampling.

The path of a forging through the plant.

04

Input material

Certified bar from renowned European mills, incoming inspection and cutting.

05

Closed die forging

Automatic mode with manipulators for series, manual for smaller orders. Hollow forging too.

06

Trimming and blasting

Flash removal and standard shot blasting.

07

Heat treatment

Aluminium forgings on a modern Realistic line.

08

Surface treatment

Pickling, grinding, polishing, passivation. Silver plating, anodising and sandblasting via partners.

09

Machining

We finish the forging on CNC machines in our machining shop.

010

Final inspection

Mitutoyo measurement and Keyence microscope. Only then do we ship.

Equipment

Forging presses.

Screw and crank presses from European makers. Our busiest press runs automatically with manipulators.

Quality from input to dispatch

A good part starts with the material and ends under the microscope.

Tyče vstupního materiálu

Input material

Bars and semi finished products come exclusively from renowned European mills. Every delivery has a certificate and passes incoming inspection.

Final inspection

We measure with Mitutoyo instruments, a profile projector and a Keyence 4K digital microscope: dimensions, radii, roughness and material sections. All gauges are calibrated.
