About Barandun Engineering

Barandun Engineering AG, based in Thusis with a contact address in Chur, offers product development, design and additive manufacturing of plastic parts. The owner, a mechanical engineer (FH) and designer with an MAS from Lucerne, designs individual parts, assemblies with up to five mutually matching parts, and complete devices including metallic components as well as prototype production. The workflow starts with interface analysis, followed by CAD modelling with delivery as a STEP file. Parts up to 300x300x200 mm are manufactured using industrial 3D printing; draft angles and parting lines are taken into account for subsequent injection mould tooling. In addition, vacuum-cast silicone moulded parts are produced, along with consulting, design and manufacturing in the field of special machinery and plant engineering. The owner runs the company as a secondary occupation; customers come from mechanical engineering, medical technology, device development and the consumer goods industry.

Materials and Processes

FDM

Industrial 3D printing (additive)

Manufacturing of parts up to 300x300x200 mm in various materials, including filament printing with PET.

PET

PET (filament)

Plastic used in the filament printer with a strength-optimised infill pattern for large, stable volumes.

Silikon

Silicone (vacuum casting)

Material for vacuum-cast moulded parts, e.g. components for luminaires.

Injection moulding preparation

Implementation of draft angles and parting lines to prepare tooling for series production.

Konst

Design (plastics and metals)

Design of parts, assemblies and complete devices including metallic components.
