In the office
- The manufacturing process of an insole begins by designing the pattern that fits in the sole of the last in a traditional manner.
- Afterwards, the shank that fits de last is chosen.
- Finally, the last is digitised to create the mould for its subsequent moulding.
These are the three pillars of a good insole, in which tradition is mixed with technology.
Once the insole pattern is obtained, it is digitised and the pieces that will form our insole are created. This is called Computer – Aided Design (CAD).
On the other hand, with the 3D scanned file, the mould is designed to the desired shape and they are created with a Computer Numerical Control (CNC) system. By manufacturing the moulds ourselves and using new materials, we achieve higher accuracy, faster production and lower costs, which allows us to maintain very competitive prices, even in small orders.
By using 2D and 3D computer – aided design techniques, we achieve a high degree of control in manufacturing, being able to make any design modification easily and precisely.
A computerised file of the model is then created with the materials, processes, photographs, measurements, etc. so that it is always manufactured identically.
At the production plant:
- The first process is to cut the CAD – designed parts, using computer – aided blade cutting machines called CAM (Computer – Aided Manufacturing)
- These parts are joined using different methods and, as a result, the insole is created.
- Which has to be moulded to give it the shape of the last.
- Bevelled at different angles to fit the shoe.
- It is then packaged, labelled and ready to be served to the costume.
This is a general explanation although there are several other processes, which depending on each insole, are carried out or not.
