A FIRM welcomed a royal guest to help mark an award-winning effort.
The Duke of Kent visited Melett to present the company with a Queen's Award for Enterprise.
The company, based at Park Mill Way, Clayton West, won the award in the international trade category after trebling export earnings to almost £1m a year since 2002.
The company provides replacement parts for a wide range of turbochargers, including ones made by Turnbridge-based Cummins Turbo Technologies under the Holset brand.
The parts are designed in-house and sub-contracted before being branded and assembled.
More than 80% of production goes overseas, to customers in more than 70 countries.
Managing director Ian Warhurst welcomed the duke, who was accompanied by Dr Ingrid Roscoe, the Lord Lieutenant of West Yorkshire.
The VIPs were given a guided tour of the premises and chatted to members of the firm's 11-strong workforce.
Mr Warhurst, who bought the business in 2002, said: "When I first became involved with Melett, it didn't take me long to realise the great potential of the company.
"All the products are produced to a very high quality and the staff provide a great personal service with excellent technical backup."
Melett was one of 145 companies UK wide to win a Queen's Award in 2006, the highest number for 11 years.
