Varianti: We aim to

implement orders as

quickly as possible with

minimum deviation from

the set parameters

Varianti Ltd is established in 1990. The company develops as a producer of custom-made

technical spring components and operates in its own production purposed building of 2300 m

2

.

It has the technical expertise of 60 membered skilled staff to meet the highest demands of its

customers in terms of quality, production time and complexity of the details.

For more than 26 years, the company has been developing its activity in Stara Zagora,

Bulgaria and has continued to take challenges by:

• producing wire details following client requirements;

• implementing batch sizes production varying from millions down to one single piece;

• managing to turn into orders over 80% of the inquires;

• ensuring excellent quality, short delivery terms and reasonable prices;

• steadily striving to develop and acquire new types of products.

Most of Varianti's rich machinery park consists of advanced CNC automats, all of re-

nowned companies such as ITAYA, WAFIOS, AIM Inc., G+M DORN, NABERTHERM.

Investments never stop. The company uses the newest available computer spring testers

by the Italian company MICROSTUDIO to ensure that the springs meet the force require-

ments the customer might have.

Varianti produces various spring shapes from round wire in diameters up to 10 mm. It mainly

keeps in stock and works with standard carbon spring, stainless and calibrated steel and

copper wires. It also has rich experience with galvanized wires and special alloys. More than

90% of the orders are covered with material in stock.

Varianti Ltd. is quality certified since 2006 and currently, a recertification according to BS EN

ISO 9001:2015 is ongoing.

Varianti produces

Compression Springs, Extension Springs, Torsion Springs, Wire Forms,

Air Copper Coils,Chokes.

The majority of orders comes from

Electrical Engineering Industry, Locksmith Systems,

Automotive Industry, Machinery Construction, Electric and Engine-driven Trucks, Food Pro-

cessing Industry, Pneumatics and Hydraulics, Agricultural Machinery, Defense Industry.

Varianti's production is exported to

Austria, Belgium Germany, France, Switzerland,

Poland, Hungary, Netherlands, Sweden, Spain, Macedonia, Serbia, Romania, Greece,

Russia, Israel.

Silmet Ltd produces chip

conveyors and hinged steel

belts

The chip conveyors can be matched with CNC machine tools and conventional ma-

chine tools which give a lot of chips - short, long and chip bundle.

There are 4 main types dependence of pitch - TSL31, TSL38, TSL50 and TSL63

respectively with pitches of 31,75 mm, 38,1 mm, 50,8 mm and 63 mm. The main differ-

ences between them are the space needed for placing and their strength.

TSL31 - with chain pitch P 31,75 mm

This type is the smallest in our production line. The thickness of hinged steel belts is

1,8 mm and the shafts are 5 mm. This type needs little space for placing and can be

matched with various machine tools, machining centers and drills, which produce small

amounts of short chips.

TSL38 - with chain pitch P 38,1 mm

The thickness of the hinged steel belts is 1,8 mm and the shafts are 6 mm. This type,

like TSL31, needs little space for placing but it has better strength then TSL31 and can

be matched with various machine tools, machining centers and drills that produce a

small amount of short or long chips.

TSL50 - with chain pitch P 50,8 mm

The thickness of the hinged steel belts is 1,8 mm and the hafts are 8 mm. This type,

like TSL63, has better strength, but it needs smaller space for placing than TSL63. This

type can be matched with CNC machine tools, conventional machine tools which give a

lot of chips - short, long and chip bundle and small press, and laser cutting machines.

TSL63 - with chain pitch P 63 mm

The thickness of the hinged steel belts is 1,5 mm and the shafts are 8 mm. This model

can be matched with CNC machine tools and conventional machine tools which give a

lot of chips - short, long and chip bundle. In case metal steel belt 63A with high tension is

used, this model can be matched with extrusion press, forging press, punching press or

laser cutting and turnkey process.

All the models can be produced with holes for better draining of the cooling liquid. The

main application of hinged steel belt is to equip the chip conveyors for bringing out the

chips from the machine tool. Transportation of small parts is possible with a hinged steel

belt. It can also be used in many other manufacturing processes, for example high

temperature processes or in the food-processing industry.
