Manuplex are underground specialists, from custom-engineered components to consumables, maintenance and repair. We engineer every component to suit the site it’s going to, with a safety-first approach. Our team of engineers understand the complexities of an underground mine from surface to seam.

Our engineering and fabrication services prioritise quality and installation efficiency, because we know the importance of keeping your equipment running with as little downtime as possible.

All fabrication is completed and quality assured in our Rockhampton workshop, fitted with manufacturing equipment to support our capabilities, including 5T overhead cranes, fabrication tooling and our team of expert boilermakers pre-qualified to AS1554.1.

Underground Engineering and Fabrication

Custom ventilation component fabrication and engineering

Manuplex specialise in custom ventilation components, with a dustless-first focus.

Our industry-leading database of VCD designs means we can tailor each component to your site’s needs, with manufacturing right in our Rockhampton factory.

Our team can customise existing designs to meet tight timeframes, site-specific conditions or safety issues. Recently, we have:

  • supplied two overcasts within a 3-week window, inclusive of sourcing material and site delivery
  • customised 50psi seal up hatches for a site’s final seals, consulting with the client to incorporate last-minute design changes to the high-pressure hatch
  • modified a coffin seal system to mitigate site issues, using an expert designer/engineer
  • retrofitted a standard grout pod with our dustless technology, creating the Dustless Grout Pod
