Germany's FW Haug GmbH & Co has been an internationally recognised name in the optical industry for more than a quarter of a century. 'Spectacle frame manufacturers throughout the world are listed among our satisfied customers,' says Daphne Tsui, general manager of Haug (Far East). 'Our strength lies in the specialisation of one industry - spectacle frame making.' The company offers a complete range of machinery and technology for the spectacle frame industry - both metal and plastic, and products are targeted at everyone, from small to high-volume manufacturers around the world. 'Our markets are global, but over the last few years we have shifted more [of our focus] to Asia, and China in particular,' Ms Tsui says. Clients include well-known German and Italian companies Ceia-Schultheiss, Crede, Felss, Locatelli, Rosler and Schussler. There are also subsidiaries in South Korea and Italy. The Hong Kong subsidiary was established in 1997. 'We are a professional and reliable partner for spectacle frame manufacturers. While software and hardware for our computerised numerical control (CNC) machines are designed from the best available components, the machines are very user friendly,' says Ms Tsui. Business has dropped since last year, mainly because of the war in Iraq, terrorism and the strengthening of the euro against the United States and Hong Kong dollars. But although Hong Kong's economy has been in a slump, demand for frame manufacturing equipment continues. 'We believe this industry will continue going up in the following years in Hong Kong. We export mainly to the US market, so it will depend on the world economy and especially on the US consumer situation because our customers are supplying their products mainly to the US market,' says Ms Tsui, adding that the euro would also be a factor. The Schussler S-610A (a modified version of the standard S-610 model) is a fully automatic CNC milling machine used for making plastic lenses. 'The milling spindle is set at a 10-degree angle to minimise the so-called over-cut traces of the cutter when milling heavy-based lenses with flat sections and rectangular shapes.' Another featured model is the Schussler S-504, a fully automatic CNC 3D eye-rim forming machine. 'The newly developed numerical control guarantees the highest possible degree of perfection, repetitive accuracy and reflects modern techniques,' Ms Tsui says. 'The hard disk with the operating system allows for a memory of approximately 30,000 eye shapes.' The Schussler S-634 is a fully automatic CNC machine that contours the milling and drilling of plastic masks and lenses.
