Accounts filed at Companies House show turnover edged up from £30.9m to £31.15m in 2012 as a £1m increase in overseas sales to £18.7m offset a drop in demand from the UK.
The Falkirk business, owned by Swiss conglomerate Franke Artemis Holding, had made a total pre-tax loss of £1.8m in 2011 because of more than £1m of exceptional charges relating to asset writedowns, redundancy costs and building repairs after storm damage.
There were no exceptional charges in the 2012 accounts although a £135,000 charge for redundancy costs was highlighted in a year when average staff numbers at the business dipped by 10 to 260.
The directors also noted the £1.2m rise in administrative expenses, to £6m, was related to the installation of a new electronic data processing system across the whole group.
Directors' emoluments dipped from £217,000 to £205,000 with the highest paid receiving £171,000.
