Case study of die-cutting a 3 mm thick PP sheet into a complex shape for a caregiving component

Customer's Challenge

Customer would like to manufacture a component for a rehabilitation device.
Is it possible to fabricate it into the shape shown in the drawing using a 3 mm thick PP sheet?

CSTEC's Proposal

This processed product involved extremely complex hole geometries. If punched as-is, the die would tend to expand, making mass production difficult.
While such cases are typically handled with machining for prototyping, this project was intended for mass production. Therefore, we adopted a method to reinforce the die.
By doing so, even complex shapes could be punched without deformation, enabling stable mass production.
For rehabilitation and caregiving devices, materials such as PP and polycarbonate are commonly used to avoid cracking. These materials are often processed by machining, but based on our extensive experience in die-cutting a wide variety of materials, we are capable of die-cutting even relatively thick materials.
In addition to die-cutting, we also offer laser processing as an alternative. We can evaluate which method is most suitable and propose the optimal solution depending on the application.
While laser processing is often associated with small-scale prototyping, the work area of our laser machines is 2 m x 1 m, making it possible to manufacture large components as well.
