102mm Pineapple stemming plugs now available !

The first production plugs have just arrived.  Some are going out to initial orders, but there are still some left.  Contact Us for details. 

First trial of our 102mm mould

We've just had the first photos of our new product arrive, with injection moulding taking place in Sydney, Australia.  Good for Australian manufacturing and good for the global underground mining industry.  Production numbers available shortly. 

See us at the Underground Operators Conference in 2020

We'll be exhibiting our new range of production and development stemming plugs at the AusIMM Underground Operators Conference in Perth, March 2020.  Details of the conference is here and the growing list of exhibitors here.  We look forward to seeing you there. 

February 2019 - 46mm development stemming

Our R&D program continues.  We are now 3D printing a development stemming plug for 46mm development blast holes.  These will be perfect for shot holes and easers in development rounds to ensure the full length of the round, and ideal for stripping.  Expressions of interest for field testing welcome. 

January 2019

The mouldflow analysis on the 102mm plug is now complete and mould manufacture is underway. 

December 2018

We have now engaged a mould maker and manufacturer for production of the Pineapple stemming plugs.   

August 2018

After a considerable amount of in house design effort in the design for manufacture stage, we are now progressing to injection moulding with the 102mm Pineapple stemming plug.  We are pleased to say we have some Australian based partners that will assist with flow modelling, mould making, and to carry out the injection moulding. 

Thanks to those mines that have already expressed an interest in what we are doing.  Please continue to contact us if you have not yet, it allows us to assess the level of interest for each size. 

The final products are looking to be injection moulded from 30% glass filled nylon, which is extremely strong and tough, and should be ideal for the task.  However, we will have the freedom to go with other materials should it be required, such as for a lower cost solution where the stemming task is not quite so onerous. 

February 2018

We now have some vacancies for field trials for those mines that have an interest in stemming upholes. Please contact us if you would like to assist in commercialising this revolutionary product.  

We have 76mm, 89mm and 102mm plugs in limited numbers ready for field trials. 

What's New 

We are currently prototyping a range of uphole stemming plugs for underground hardrock mining. 

The design is the result of significant research and development, including design for manufacture so that they can be made cost effectively. 

Prototypes are being field trialed so we can implement any necessary design changes prior to full scale manufacturing. 

In the interim, we are preparing a limited number of plugs available for purchase prior to full production.  Please contact us if this is of interest to your mine site.
