Administrators for Queensland manufacturer PPI Corporation have restarted production at the company's Brisbane facility, with 40 employees returning to work on site.
PPB Advisory were appointed voluntary administrators at the end of January and at the time of the company's initial collapse all production was halted.
Some workers have since returned to operate six production lines that will make pipe products for the domestic and mining markets.
Administrators said demand was still strong for PPI products and recommencing production would help deliver an immediate cash flow for the business.
PPB said it would look at recommencing other parts of the business as the sale process continued, but any step to increase production would need to generate a positive cash flow.
Administrators said 36 parties had registered an interest in buying PPI.
Around 300 staff were stood down when the company collapsed earlier this year.
