Process 

We started of by analysing the demands of a crampon for the recreational market. The existing 3D formed stainless steel crampons are indestructible, have extreme grip but come at the price of cost and in some snow conditions snowballing. The new crampons it was agreed that weight, cost and anti snowballing was on high priority. It was established early on that the crampons should be produced using a process suited to high volumes and thus in a thermoplastic. The chosen material is a glass filled polyamide, it handles cold well and is good against abrasion. Due to abrasion and strength switching from metal to polymers  there was a lot of resources put into reforming the geometry of the crampons. We used a tight cycle of 3D modelling and physical testing from 3D printed prototypes to arrive at an optimal solution. The result is a crampon that makes the product as a whole more affordable, lighter with reduced snowballing but at the slight cost of grip and durability.
