Progress based on tradition"There is no past without the future"

S ince the Company's founding in

1890 SCHERDEL has always

demonstrated an innovative approach,

committed to progress. Now, as in the

past, great importance is attached to

the use of new technologies, which are

regarded as an opportunity for growth

and rationalization. As early as 1915

SCHERDEL was using automatic

machines for the manufacture of

springs. The following are just a few

examples of the Company's tradition-

ally progressive attitude: the first use

of the shot-peening process in Europe

in 1936 to improve the service life of

engineering springs; the introduction of

assembly-line production for compres-

sion springs in 1943; the development

of the SCHERDEL "Ultra" process in

1956 as a solution to thermal problems

relating to valve and clutch springs;

and the introduction of stress-opti-

mized production at the end of the

1980s. This visionary approach has

always been an outstanding feature of

the SCHERDEL Management – start-

ing with the Company's founder,

Sigmund Scherdel, followed by his

sons Max and Rudi Scherdel, and now

the present head of the Company,

Walter Bach, under whose manage-

ment the Group's research and devel-

opment activities are continuously

being extended, in accordance with

the corporate motto: "Progress based

on tradition".

SCHERDEL worldwide"Reaching a limit shouldn't mean: This is where you stop, but rather:

This is your chance for growth"

T hink globally – act locally: today,

true to this motto and with 26

locations worldwide, the SCHERDEL

Group can always provide its clients

with a locally based service. With

the single European market in mind,

the course was set at the end of the

1980s for the successful international-

ization of the Company. This policy of

expansion began with the take-over of

existing firms in France and Portugal.

Following German reunification, an

important member joined the Group –

the Marienberg spring-production fac-

tory in Saxony. SCHERDEL then

looked towards Eastern Europe, and

companies were founded in the Czech

Republic, Slovakia and Poland. The

activities in relation to new locations

have focused on the USA, Brazil,

Mexico and the growth market Asia,

the emphasis being on China.

SCHERDEL Group Managing Director,

Walter Bach, has declared that, in

addition to the internationalization

of Company locations, future Group

policy will focus on enhanced quality

and efficiency.

Engineering springs"The slightest movement affects the whole of nature"

I n relation to the manufacture of

engineering springs and the expert-

ise that this requires, the SCHERDEL

Group has led the field for more than

100 years now. Here, engineering

springs are often used to solve prob-

lems which demand the highest techni-

cal standards. The valve spring, for

example, is a small but nevertheless

highly stressed component for piston

engines. Its quality is crucial to the

service life of an engine. Particularly in

relation to the design and manufacture

of valve springs, SCHERDEL possess-

es outstanding know-how and many

years of experience. After all, the

world's first diesel engine was

equipped with SCHERDEL valve

springs. However, engineering springs

are not only used in the manufacture

of motor vehicles (e.g. for gears, ABS,

fuel injection, carburettors, braking

systems), but also in the building and

furniture industries, in measuring and

control technology, in the manufacture

of various types of appliances, and in

electrical engineering and electronics

(e.g. switches). In addition to the valve

springs already mentioned, the range

of products includes compression

springs, tension springs, disk springs,

torsion springs, retractor springs, con-

stant force springs, spiral springs,

sleeve springs and also spring ele-

ments for oil distribution rings.

Engineering springs are the invisible

helpers and problem-solvers in a mod-

ern world which would certainly be less

mobile without them.

Vehicle components"For the whole must be prior to the part"

S CHERDEL'S engineers and

development technicians always

have the whole product in view when

they play their part in enhancing the

standard of comfort and convenience

in modern vehicles. Criteria such as

safety, weight reduction and functional-

ity are also of prime importance in the

manufacture of metal structures for

vehicle seating. Often enough it is in

assembly components that the engi-

neering spring – one of the

SCHERDEL Group's core products –

really comes into its own. No matter

whether it's a question of adjusting and

compensating components with spiral

springs, switch systems, or mecha-

nisms for adjusting and actuating

systems: in the development and

manufacture of these products the

emphasis is on cost optimization, long

service life and reliability. Today, in

close co-operation with the automotive

industry, the ideas for tomorrow's

vehicle components take shape.

Stamping and bending technology"I bend but I do not break"

O f course SCHERDEL's stampings

and shaped components are

flexible problem-solvers, but when it

comes to the crunch they can take any

amount of punishment. There are

innumerable products in this field: wire

rings for fastening or for use as cir-

clips, contact elements and blanks,

terminal housings for electric motors,

retaining elements for windshield

wipers, contact components for ve-

hicle-seat heating systems, hinge

elements or shielding plates and

retaining belts, to mention but a few

items from the extensive production

program. In the manufacture of stamp-

ings and shaped components, preci-

sion is particularly necessary when

working with material thicknesses

down to 0.06 millimeters. These com-

ponents have a wide range of applica-

tions and an equally impressive range

of customers from widely varying

fields: the automobile and automotive-

parts industries, manufacturers of

household, electrical, sports and

leisure articles, or the furniture indus-

try.

Connection technology"The greater a thing's unity, the more perfect its goodness and effectiveness"

I f it's a question of guaranteeing reli-

able connections in the field of auto-

motive engineering, then hose clamps

made by SCHERDEL are the answer.

Whenever tube and socket connec-

tions must be perfectly sealed to en-

sure the reliable functioning of techni-

cal components, then dependable,

maintenance-free hose clamps provide

the ideal solution. Since they are self-

adjusting, they adapt to varying en-

vironmental conditions and ensure

complete functional adherence despite

the constantly changing service condi-

tions in a motor vehicle. In order to be

able to offer all its customers the

greatest possible expertise in the fields

of development and production,

SCHERDEL, as a leading producer of

coil springs, founded a joint venture

under the name of TOGO SCHERDEL

with the Japanese Togo Seisakusyo

Group, which is the market leader in

the field of hose clamps. Thanks to the

combined know-how available in this

partnership, they can produce standard

and space-saving hose clamps, as well

as pretensioned and double hose

clamps with outstanding design-related

advantages and enhanced efficiency.

These products are particularly suitable

for use in coolant circulation systems,

servo systems, fuel systems, charge-

air and air-intake systems or for direct

injection processes under variable

overpressure or vacuum conditions.

Assembly technology"It is through the laying of foundations that greatness of any

kind achieves lasting fame"

Whenever product development

work involves laying the founda-

tions of new systems and components,

then SCHERDEL's Assembly

Technology Division can provide the

necessary expertise right from the

start. No need for the customer to get

involved in development and assembly

work or logistics. Instead, he can order

individual parts or complete compo-

nents ready to be installed, in small

lots or large numbers, as required. The

careful co-ordination of a wide variety

of materials and possible coatings,

combined with cost-effective assembly

concepts, ensures an optimum service.

Whether it's a question of manual work

or fully automatic series production in

three shifts, continuous quality checks

guarantee that even the most stringent

customer requirements are satisfied.

The range of products made by the

Assembly Technology Division inclu-

des spring packs for automatic trans-

mission, spring supports for vehicle

tailgates, return springs for variable

valve-train systems in engines or, for

example, pre-assembled tambour door

systems with integrated torsion springs

for the furniture industry.

Machines and Systems "For it is the spirit alone that brings technology to life"

M achines and systems would

be of little value if they didn't

originate from some ingenious idea,

the realization of which opens up new

possibilities, reduces costs, rational-

izes work processes or even improves

conditions at the workplace – by

reducing noise, for example. Working

at top speed and with total precision,

the CNC milling machines produced by

the SCHERDEL Group can perform

any task in the field of wood, plastics,

aluminium and metal working. Using

movable portal machines or mobile

supporting tables, workpieces and

semi-finished products can be given

careful 5-axis treatment from start to

finish, with only one initial clamping

procedure. The range of products

also includes coordinate and single-

axis tables, tool magazines and tool-

handling systems, pallet-exchange

systems and machine housings.

SCHERDEL's special wire-working

machines rank among the top

products in their segment of the

market. For projects involving the

modernisation of existing heavy

machines, committed engineers and

technicians work out individual solu-

tions. Here, state-of-the-art production

techniques and calculation methods

guarantee that today's machines will

be able to meet tomorrow's challenge.

Automation and control technology"The way is the goal"

H ow can we ensure that the way

to our goal is as fast, as accurate

and as smooth as possible, so that in

the case of repetitive handling opera-

tions no variations or deviations occur?

Finding an answer to this question

resulted in a world patent: the

ZARIAN®-Z2 drive principle, a

SCHERDEL Group invention consist-

ing of a toothed belt which rolls on a

toothed rack mounted parallel to a

guide mechanism. This invention pro-

vides the basis for linear modules and

multi-axis systems, skilfully combined

with ingenious control techniques and

peripheral devices such as grippers.

This not only optimizes workstation

procedures but also relieves staff of

the task of carrying or lifting heavy

loads. The system uses portal loaders

which can handle heavy components

and perform difficult lifting operations

with the greatest of ease. Thanks to

modern, automatic assembly equip-

ment, production time can be reduced

considerably – another cost-saving

advantage. The field of automation

and control technology also includes

the development of all-in-one solutions

comprising the construction of individ-

ual special-purpose machines with

corresponding software development

for SPC and CNC control systems

including the construction of control

cabinets.

Tools and equipment"If you want to do a good job, only the best tools will do"

I n tool-making SCHERDEL aims to

meet the highest standards. Here,

inspiration and creativity, combined

with careful planning and the expertise

to know what is technically feasible,

provide the basis for the design and

manufacture of highly complex tools.

For this work, the SCHERDEL Group

can call on the experience of a highly

committed staff and state-of-the-art

technologies: modern CAD equipment

with online data transfer to the cus-

tomer is used for the production of

3-D models. In the developers' network

this 3-D data generates the technology

programs for controlling the machining

process. The DNC data-networked

machinery includes efficient facilities

for wire-EDM and NC three-axis and

five-axis machining, as well as HSC

milling machines for high-speed cut-

ting, or pressing and stamping

machines able to exert a pressure of

up to 600 tonnes. SCHERDEL's

expertise is also evident in the manu-

facture of punching, bending and

stamping tools, jigs and fixtures, refer-

ence gauges, follow-on composite

tools and transfer tools, isostatic

pressing tools and peripheral equip-

ment for automatic handling machines.

Here, SCHERDEL has set standards

of quality and precision which are hard

to beat.

Surface finishing"Values can only be preserved by change"

B y applying special coatings to

alter the surface finish of techni-

cal components, corrosion can be

prevented and their service life can be

considerably enhanced. However, the

characteristics of the material of which

the parts are made can also be modi-

fied in such a way as to produce func-

tional advantages: for example fric-

tional resistance can be reduced, or

protection can be provided against

acids, alkalis and contact corrosion. In

the field of surface finishing, the

SCHERDEL Group not only has the

necessary know-how but state-of-the-

art technology as well: the equipment

includes a computer-controlled zinc-

phosphating unit which also sets stan-

dards in relation to environmental pro-

tection, a TULZ installation for coating

parts with complicated geometry,

standard Delta Tone and Delta Seal

installations, modern spraying equip-

ment, as well as powder-coating and

electro-dip-coat (KTL) installations.

In the central laboratory there is a

scanning electron microscope for

documenting layer formation. The

scientists' work also includes quality

assurance involving the preparation

and examination of metallographic

sections and the use of equipment for

salt-spray, Kesternich and damp-heat

testing procedures.
