Spare Parts

Along with machines, Kromtel is providing quality spare parts for all kinds of machines with reasonable prices.

Spring Testing Machines

With Kromtel’s spring testing machines you can test compression, tensile strength, twisting, breaking and other test, all of which can support your customers and increase your sales performance.

Heat Treatment Furnaces

Furnace can be use for prestressnig process for various sizes of springs. These furnaces can be used for springs with wire diameter between 0.10 mm and 30 mm, with power from 4 kW up to 300 kW and with temperature up to 500 °C.

Spring Grinding Machines

Designed to work on both ends of the spring at the same time, machine is equipped with two rotating grinding wheels. Mechanical, PLC and CNC can be controled in many ways. Spring with big wire diameter and big outside spring diameter can be used on this machine as well.

Garter Spring Former and Jointer

Machine has special design for garter springs and jointers with wire range from 0.15 mm up to 0.80 mm.

Machine is supplied with 2 AC motors. For coiling springs with precise length dimension, there is lenght control sensor.

For garter springs production, additional unit can be installed.

CNC Wire And Pipe Bending Machines

With wire diameter range between 2 mm and 13 mm and with 3D wire rotating head, this machine is designed to bend wires in various sizes and raiduses.

Specially it is recommended for production of wire shapes with biggers sizes and diameters.

Machine is equipped with wire feeding, rotating and bending axis.

CNC Compression Spring Coiler

Exclusive compression spring machines for making coil spring, having a powerful drive and durability-oriented design. And so anyone can operate it easily with simple program.

It starts with 2 axis (wire feed and cam group) and goes up to 11 axis.

Kromtel’s compression spring machines can produce springs using all type of hard drawn wires (high carbon steel wires, stainless steel wire, oil tempered spring wires) with the diameter range of 0.10 mm – 23.00 mm.

According to needs of the customer, number of axis and optional specifications can be added by the technical staff of Kromtel.

Optional specifications:

  • Right-left coiling
  • Length-control unit
  • Torsion spring coiling unit
  • Rotative cutting system

CNC Spring Forming Machines

CAM Type Spring Forming Machines

Wire forming and cutting functions are performed by means of 8 pieces cams and with the power of single motor.
It has minimum 3 axis which are cam axis, wire feed and quill rotating axis. Economical solutions are provided with additional wire rotating axis, spinners (x2) and second hook stations, for the high volume works.
Working range of the cam type spring forming machinesis 0.30 mm – 8.00 mm.

CAMLESS Type Spring Forming Machines

Special camless design equipped with free arm technolgy that enables our series of spring machines to easily produce all kinds of difficult springs that is 30% or more efficient than traditional cam type spring former.

Feature Highlights:

  • Windows based operating system.
  • Advance attachments such as rotary wire, spinner, and the x-y free arm can be optionally equipped to the machine.
  • Intuitive graphics user interface is based on Windows and its crash free
  • Characteristic is due to the employment of a bullet proof software engineering methodology. This makes learning and configuring highly complex springs a simple task.
  • Commonly use in the industries of: automobile, wire forms, entertainment and fitness.
Torsion Spring Machines

It works with the principal of wire forming on a central pin or mandrel.

Beacuse it forms the wire on a mandrel, it is more accurate in comparison with other machines for the outer diameter and position of the spring.

Axises are can be grouped as cam groups, pitch and forming groups.

Working range of these machines is 0.15 mm – 4.00 mm

With the additional stripping device on the back of the machine, it is also possible to produce air coil springs.

Stainless Steel Seamless Pipe

Production range of stainless steel seamless pipes is as follows: 

Outside diameter (Φ6mm-Φ610mm), wall thickness (0.6mm – 30mm).

Main materials: 304, 304L, 316, 316L, 321, 310S, 317L, 347H, S31803, 2205, 904L, etc. These pipes are widely used in petroleum, chemical, paper, medicine, shipping, heat exchangers and other industries. 


Stainless Steel Welded Pipe

Production range of stainless steel seamless pipes is as follows: 

Single slit: Outside diamameters (Φ8mm – Φ630mm), wall thickness (0.5mm – 25mm)

Girth: Outside diameter (Φ630mm – Φ3000mm), wall thickness (3mm – 45mm).

Main materials: 304, 304L, 316, 316L, 32,1 310S, 317L, 347H, S31803, 2205, 904L, etc.

These pipes are widely used in petroleum, chemical, paper, medicine, shipping, heat exchangers and other industries.

With the experience, responsibility, and work ethics we have gained in the industry since 1989, it will always be our unchanging passion to provide service to our esteemed customers at an increasing level of quality and satisfaction.
