Springs & spring making

High speed coiler SPX Precision Components, FENN Division offers a range of Torin Z type CNC high-speed spring coilers using a combination of high torque servomotors and

A large variety of springs and metal parts

state-of-the-art motion control technology for the high-speed production of springs. Additionally, the system mechanics are specifically engineered to reflect the lowest inertia possible. This high torque to inertia ratio provides the greatest degree of coiler responsiveness and is critical in the production of springs at high rates. Another feature contributing to high-speed production is the servo rotary cut system on most models with left and right hand cutter shafts as standard. Fully computer controlled using powerful, specially developed software with an easy to use

Hang Cheong Metal Factory began business in Hong Kong in the 1970s. In 1996 the production line was moved to Hong Sheng Industrial Town and now occupies a 2,000m 2 facility. Hang Cheong Metal Factory is ISO 9001:2000 certified. All products meet international quality standards, for example Japan (JIS), USA (ASTM) and Germany (DIN) and also pass the RoHS test report. The company operates the following plant and machinery: computerised spring former, length inspection machine, forming machine, wire cut machine, heat-treatment machine, temper furnace and sleeker.

operator interface reduces set up times and provides on-the-fly adjustment of spring parameters. Changeover time is greatly reduced due to a new tooling concept where one set of feed rolls and wire guides cover the full wire range. Most models are available with up to six-axis covering torsion and lateral coiling point increasing the product range and flexibility of the machine.

Within compression springs the focus is on difficult springs, such as hot pre-set compression springs as needed by the hydraulics sector. All compression springs are customised and are available in sizes from 0.10mm to 13mm. The wire material is usually oil-tempered, music wire, or stainless, but can also be in special alloys and round, square or flat. The compression springs are available ground or un-ground, as required.
