Case Study

Sector: Plastics Moulding

Type of part: 5m Auger Screw

Production Type: One off conveyor machine part

Customer Requirement:

A local plastic moulding business had production shutdown after their conveyor system went down. The part required would take weeks to arrive from the manufacturer and that meant a closed production line.

Engineering Solution:

After an initial discussion CBS analysed the broken part, an auger screw. We identified and sized up the required material and ordered in stock. We then set up the tooling to replicate the 5m screw.

Production Solution:

Within days, the conveyor system was back up and running and the customer could get back to production. Taking a 3 week loss of production and reducing it to one.

Current State: Conveyor System up and running with 2 weeks production time saved

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.
