PROTOTYPES

Aerni also develops and constructs prototypes and small series of apparatuses and plants. Prototype construction is carried out in close cooperation with the client.

Beratung
Step 1
Consulting

The consultation begins with an interview, during which the client’s specific requirements are identified. In the process, Aerni can draw on the many years of know-how gained from numerous plants and vessels already constructed.

Step 2
Indicative price offer

Once the technical specification has been defined, an indicative price offer is prepared for the prototype based on this and discussed with the client.

ENTWICKLUNG
Step 3
Development

Aerni’s engineering department designs the prototype based on the technical specifications and creates a 3D CAD model as an approval drawing for the client.

Binding offer
Step 4
Binding offer

Based on the 3D model, a binding offer and a project schedule are subsequently prepared and discussed with the client.

Production drawings
Step 5
Production drawings

Once the price has been agreed and the 3D model and project schedule have been approved by the client, the construction details are worked out and the production drawings and production papers for manufacturing are prepared.

PRODUKTION
Step 6
PRODUCTION

A prototype is constructed on the basis of the production drawings and any accessories are assembled.

ABNAHME
Step 7
Acceptance

The necessary tests are carried out and, if desired, the acceptance takes place together with the client in the specially designated acceptance room. Upon request, a manufactured prototype can also be produced in series at any time.
