Montupet believes a row between one of its major customers, Ford, and an American tyre manufacturer, will not have a long-term impact on its Northern Ireland operations.
However, the French car components group plans to enforce a two-week short-time working period in its Derry plant because of the row.
The dispute between the Ford motor car company and Firestone, the tyre manufacturer, is over the performance of tyres used mainly on the Explorer sport-utility vehicle.
Montupet's Calcast plant in Derry makes the engine heads for the Explorer model, which are shipped to Ford's plant in Cologne.
Assembly of the vehicles has been halted at two plants in the US and the German plant will not produce machine cylinder heads in the Northern Ireland plant during July or August.
According to Mr Daniel Cofflard, Montupet's managing director in Northern Ireland, production at the Derry plant is expected to return to normal after the summer.
The Derry plant exclusively produces cylinder heads for the Explorer vehicle and does not currently manufacturer any other product.
However, Montupet is hopeful that in time the plant will expand its product range.
The group's Dunmurry plant, on the site of the former De Lorean factory, produces five different cylinder heads for a number of car manufacturers including Peugeot and Renault.
Montupet acquired Calcast, formerly known as Transtec, out of receivership last October. Montupet's decision to rescue the Derry plant effectively saved the jobs of more than 200 workers in the North.
Ford announced last week that it planned a further recall of Explorer vehicles following a series of fatal accidents involving the vehicle. The American car giant was Firestone's largest customer and the two companies had done business together since they were both first established, 95 years ago.
To date there have been 174 deaths and 80 injuries in the United States which have been linked to problems with the Firestone tyres fitted to the Ford Explorer, one of the world's most popular 4x4 vehicles.
