Machine for manufacturing PTFE liners

Special-purpose machine for lining steel pipes with PTFE liners: the pipe is placed with the jib crane and clamped in the holder, then the machine draws in the liner. Operator platform, cable carriers and controls are part of the design – from the 3D model to the manufacturing drawings.

02 · CFD & FEM Analysis

Simulate instead of trial and error

Simulations replace costly manufacturing iterations: the operational strength of a design is verified before anything is made.

More about FEM & CFD simulation →
02 · CFD & FEM Analysis · Flow field

Flow made visible

The animation runs back and forth and shows how cooling air spreads through the housing – vortices, dead zones and bottlenecks become visible before a prototype is built.

More about CFD simulation →
Simulation of flow and heat dissipation in a device housing
02 · CFD & FEM Analysis

Heat & flow

Combined simulation of heat and air flows shows which temperatures occur in operation – each line is the path of the cooling air through the housing.

More about CFD simulation →
02 · CFD & FEM Analysis

Natural frequencies

Frequency ranges are shifted by adapting the geometry so that components neither vibrate nor fatigue in service.

02 · CFD & FEM Analysis · Structural analysis

Loads made visible

Scroll through the simulation: the structure is loaded step by step, the colour scale shows stress from low to high.

More about FEM simulation →
02 · CFD & FEM Analysis · Structural analysis

Load application

Forces and moments are applied as they act in operation – derived from the design, not estimated.

02 · CFD & FEM Analysis · Structural analysis

Stress analyses

Highly loaded structures are checked for stress and dimensioned precisely – material where it is needed, saved where it is not.

Deformation & safety

The exaggerated deformation makes component behaviour easy to understand; the safety factor decides on release for manufacturing.

Your design status – in real time

No e-mail attachments, no outdated drawings: whatever is released on our side is in your project folder minutes later.

  1. 1Design at Heger CADWe work in Inventor, and every change is versioned in Vault – nothing is lost, every revision remains traceable.
  2. 2Release & automatic synchronisationAs soon as a revision is released, it is transferred encrypted to your personal project folder – without anyone having to write an e-mail.
  3. 3Current status on your sideDrawings, 3D models and parts lists as PDF, DWG or STEP – any time, on PC, tablet or phone. Your purchasing, manufacturing and assembly always work from the same revision.

On request in the other direction too: your specifications, review notes and red-pen comments reach our designers by the same route.

    The test rig

    Function comes first: a test rig built from standard parts shows whether the principle works – before a single manufacturing drawing is made.

    The first design

    The principle becomes a design: drive, spring pack and fixture take shape in 3D CAD – the section view makes every function easy to follow.

  3. Finished development with guard and operator panel
