Springs & spring making
A large variety
of springs and
metal parts
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 2,000m2 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.
Hang Cheong Metal Factory
specialises in all kind of precise
spring (compression spring, extension
spring, torsion spring), wire formation
products (from wire diameter 0.04mm
up to 12mm), pin, axles, iron shafts
(drill pointing, thread rolling, heading),
metal fittings and parts. Products are
mainly supplied to foreign businesses
with factories in China, but also to
Hong Kong, Europe, USA, Japan and
other countries.

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
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
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.

Springs from Sweden
Scandinavian spring supplier, Spinova AB specialises in compression springs, torsion
springs and wire forms. 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.
Customised extension springs can be manu-
factured in spring wire, stainless steel wire or
other special alloys, in wire dimensions ranging
from 0.10mm to 13mm and in various hook
designs.
Spinova can also supply torsion springs, single
or double coils with various shaft designs.
Established in 1975, Spinova is part of the
European industrial conglomerate Indutrade
AB, present on most European markets.
