Coesum takes care of product development from design to mass production

Customer objective: To develop the outer casing of an olive harvester. Initially the customer was in possession of only the internal motor, battery and other accessory parts to be inserted into two half-shells.

Coesum solution: The customer shared with us the product specifications and thanks to the continuous dialogue, the overall analysis of the project, the knowledge of materials and production processes, we were able to create a new innovative product in the form and optimized in function and in costs. COESUM followed the study of the two half-shells from design to engineering, rapid prototyping and mass production from plastic injection.

Results: In just a few weeks, the customer was able to have the first rapid prototyping shells to carry out function and assembly tests on the product. Once the engineering phases on the product were completed, we immediately moved on to the design of the molds to start mass production.

The client for this project has completely relied on the experience and development capacity of new Coesum products. Initially we shared the operating specifications of the product, the internal components that had to be housed inside the two half-shells; the engine, the battery, the beater output tube and other accessory parts. With this information we started with the study of a form that could contain all the components and at the same time guarantee an ergonomic and functional capacity for the product.

Once the shape and thickness have been defined, we have first of all made prototypes to carry out product assembly tests as well as test their functionality and ergonomics. In this case we used selective nylon sintering (SLS) a rapid prototyping technology that guarantees good mechanical strength and allows functional tests.

The next step was to engineer the 3D CAD drawings in order to make the project ready for industrial production. We have also finalized the molding materials and the assembly methods of the product as well as the technical and functional aspects of the individual parts (housing and assembly of the batteries, inserts, poppets, etc.). This phase also allows defining project details in order to reduce mold costs and optimize the production process.

After the customer confirmed the 3D files we started the design of the steel molds for production with PA6. At the end of the construction of the molds a first mold test was carried out to validate also the final production and to start the series production.

A new challenge overcome with great satisfaction for a new product!
