Case Study
Sector: Medical Equipment Manufacture
Type of part: Small Compression Spring
Production Type: Part Production & Clean Room Assembly
Customer Requirement:
The current assembly was not operating as required on a safety blood device. A small compression spring seemed to be the issue. They contacted CBS to see if we could help.
Engineering Solution:
Our engineering team analysed the spring and the assembly, to better understand the operational requirements the spring needed to meet. Using a cross section and modelling, we were able re-design the spring and reduce the tensile strength of the wire giving perfect results.
Production Solution:
Due to the very small compression spring part, delivering in bulk often causes tangling and this was slowing production down for the customer. CBS offered an assembly solution that improved production by assembling the unit in a clean room environment, straight off the coiling machine. The completed assembled parts are then delivered to the production facility. This also meant that we could omit heat treatment from the process, increasing production.
Current State: Delivering assembled units to customer exactly when required.
