The customer required a functioning torsion spring for use in a new joy stick. The customer requested that Advanex design and develop a spring that would repeatedly work through the full range of movement required.
To strengthen the customer’s relationship with Advanex, we arranged for the customer’s engineers and ours to communicate directly due to the complex nature of the project. After their discussion, the engineer at the Koriyama prototype factory designed a spring that was, in theory, up to the task and sent the drawings to the customer.
Using a numerical control multi forming machine in the prototype factory, they then produced a sample with more coils to reduce the fluctuation of stress and avoid spring setting and adjusted the leg angles to give the customer’s required torque levels and aid durability.
In all, five prototypes of the spring were produced. All communication was done via telephone calls and e-mail exchanges with the customer, who appreciated the rapid response from Advanex. During this development the customer then order a compression spring, which further demonstrated their faith in Advanex’s capabilities.
