Chamberlin, the specialist castings and engineering group, continues to expect revenues for the year to be substantially ahead of last time but said underlying profits were now expected to be in-line last time.
The group said revenues for the first six months of the current financial year were in line with management expectations, reflecting overall good levels of demand across the foundry and engineering businesses.
But it said margins within the group's foundry businesses had been adversely affected by production issues.
It said that at the new machining facility technical difficulties had created cost inefficiencies and extended cycle times.
The company said it was addressing these issues and was working very closely with the machine and tooling suppliers to rectify the situation
