DISA has launched the DISAMATIC C5 vertical green-sand moulding line, designed for high efficiency and low operating cost. The system can produce 400 uncored or 340 cored moulds per hour, delivering up to 20% higher output than comparable machines while reducing maintenance needs and total cost of ownership. The company said the C5 improves casting quality, cutting grinding and rework by about 50%, and offers fast installation with compatibility for existing pattern plates. Overall, the new line enhances productivity and supports faster return on investment for foundries.

The Rio Tinto-owned Tiwai Point aluminum smelter in New Zealand faces strike risk, with 186 workers, about 28% of the workforce, planning stoppages on May 4, 6, 8 and 10. The action follows around 2.5 years of unresolved labor negotiations over pay, benefits and working conditions. The company has proposed mediation on May 20 to reach an agreement. While management said current terms remain competitive and negotiations are ongoing, the planned industrial action could disrupt production schedules and operational stability at the smelter. If talks fail to make progress, the risk of prolonged disruptions may increase, creating uncertainty for near-term aluminum supply and adding pressure to an already tight global market environment.

Nexans has acquired 100% of US-based aluminium and copper wire producer Republic Wire, with an enterprise value of about USD 734 million and an earn-out of up to USD 46 million.

Nexans said the deal aims to expand its presence in the US low- and medium-voltage cable market and strengthen its distribution network. The transaction is expected to close in Q3 2026 and generate about USD 250 million in synergies over three years, supporting long-term growth in North America.
