Case Study - Number 1


The challenges faced with this particular project where the over moulding of a complicated metal fabrication that was only 0.3mm thick whilst maintaining tight tolerances of + or - 0.02mm, this coupled with having a restricted feed position and warpage having to be kept to a minimum using a crystalline material set a task that tested all aspects of both the tooling & moulding processes.

APQP: Required
Part Spec: Nylon 6
Mould Flow: Required
Tool: Fully hardened tool
3D Model: Not Required
Summary: This part is for our own product range and the reason we decided to feature it is because it has 3 different sets of inserts that we can change on the press so we have no down time. It means basically that 1 part can make an additional 2 variants.

Case Study - Number 2


The challenges faced with this particular component where not only the thread form requirement but also the interchange ability of the pin configuration from 5 - 8 hole.
The tool had to be designed in such a way that we could change the pin configuration with ease but also get sufficient cooling around the thread area to maintain the tight tolerance requirement.
To overcome this we manufactured Trojan alloy core pins to run through the centre of the unscrewing core, this gave us the ease of interchange ability, cooling requirement for the thread and provided the lubrication requirement for the unscrewing core to rotate around the pin.
