Sand testing laboratory resource centre.

Casting defects not only affect quality, they impact your profit margin and competitiveness too. Unfortunately, recognising casting defects is one of the most challenging burdens confronting metalcasters.

The good news is there is an answer for every defect. Imagine having the right sand testing equipment instrumentation in your laboratory to give you the analysis you need to better control your materials and processes to reduce defects.

42160 digital pneumatic squeezer: More representative of modern moulding machines when compared to the traditional 3-ram method the 42160 utilises high-pressure squeezing to provide both more consistent and accurate results and displays the results on a digital display. This easy to operate device eliminates operator error and is used to prepare and determine compactability of a standard test specimen.

PAB-P pneumatic ejector: Eliminates human operator influence by using the PAB-P for an automatic and soft ejection of the sand specimen from the specimen tube. With the PAB-P there is no additional post-compaction of the test specimen which can occur with a more manual extraction method.

PGD-E gas pressure measuring device: Better understanding of core gas volume levels will allow a foundry to better control gas defects which occur during the solidification phase. The PGD-E determines gas pressure and core gas volume by heating core sands which can be displayed on a computer as a pressure-volume diagram for visual, easy to read data analysis.

42112 wet tensile strength tester: Control expansion defects by utilising data provided by the 42112. This device determines tensile strength of the condensation zone by utilising a heating element to recreate the environment at the mould metal interface.
