Midland Pressure Diecasting offers a non-destructive testing (NDT) inspection service utilising real-time x-ray technology. This specialised equipment allows MPD to analyse in detail the internal integrity of castings without disturbing or having to cut into castings and providing input to optimise our process settings without any production downtime.
This technology can be utilised for the following:
Process and quality control,
Research and development including product and tool design.
Benefits of this technology include:
It is a non-destructive testing process – parts are not changed in any way and can be used afterward,
Multiple x-ray capture from a variety of angles,
Analysis of internal assemblies including whilst assemblies are in motion,
Comparison analysis – Defective part vs. Good, Before vs. After etc.
This service can be offered to customers who insist on the most thorough quality inspection in-line with our ISO 9001 quality management system.
Investigation into component internal integrity and implemented improvements
Midland Pressure Diecasting were asked to look into castings which were causing issues after the parts were being machined. The castings themselves from a visual and dimensional point before further machining looked okay, after machining however the issues were becoming apparent. Due to how the customer inherited die casting tool was designed with a conventional in-gate runner system, after component cooling sub-surface shrinkage porosity was forming in the critical thicker sections which were being machined (darker sections on the x-ray images). Upon MPD x-ray inspection this was clear to see immediately after sampling the tool.
With MPD’s expert design advice to modify the tool with the simple implementation of increased radiuses added to the sides of the in-gate feed system to promote a wider more balanced material flow around the die casting cavity and into the overflow on the opposite side of the casting the issue was resolved for the customer with minimal cost implications for the required tooling modification which MPD did in-house.
