Service & Maintenance
Among others the plugs of peripherally bored calender rolls, irrespective of their plug system, can be replaced. And also calender rolls with different kind of seals can be treated (opened, cleaned and closed again).
The tightness will be checked by pressure test at ambient or working temperature.
Finishing
To obtain the best possible quality, once ground to the desired diameter, the roll can be polished or matted.
By polishing of the roll’s surface, the roughness will be reduced to the requested value. This can be done either by simple polishing or superfinish polishing.
By matting of the roll’s surface, the roughness will be raised to the requested value. The kind of blasting material determines the shape of roughness.
Both ways of processing are independent of the roll’s material. All common types of steel and cast iron can be polished or matted. The same goes for rolls which have been chrome-plated or nickel-plated.
The combination of both types of processing is also possible.
Turning
Available turning machines enable to provide all services on workpieces with dimensions Ø 1100 mm (above slide) / Ø 1600 mm (without slide) x 12000 mm total length and a weight of up to 25 tons.
Nickel Plating
In case of heavy wear, the original diameter of the roll can be restored through the nickel-plating process.
Since the nickel layer is almost as hard as the chrome layer, a roll with nickel beneath the covering chrome layer does not have any limitations during the production process.
Chrome Plating
Vertical chrome plating tubs offer sufficient capacity to treat any size of roll.
Any demanded thickness of a layer will be precipitated with the best possible structure. In particular applications of the chrome-plating technique electrolytical mattings can be produced.
Upon request, the hydrogen produced during the chrome plating, which has been stored in the chromium layer due to the process, is outgassed by heating the roll. This process is known as dehydration.
Grinding
With the available grinding machines very big and heavy rolls can be ground with maximum precision. Rolls up to 3500 mm in diameter and a maximum face length of 10000 mm can be worked with great accuracy.
The CNC technique gives the ability to produce any requested profile of the face. The deviation of the profile’s target can be limited to 1 µm. The result of grinding including run-out and concentricity is made out and printed electronically.
Possibility to do grinding of rolls with exactly the temperature the customer uses during the production process.

Profile powdering
Profile powdering is applied in extrusion lines for rubber or silicone strips, hoses or profiles.
Calendered sheet powdering
Calendered sheet powdering allows the adhesion to be avoided during the winding process of the sheet.
Suitable for a useful width of 500 – 3000 mm.
Rubber parts powdering
Rubber parts powdering is done by means of a grooved conveyor belt, which allows continuous adjustment of the powdering grade as well as of the speed of the line.
Cable powdering
Cable powdering is based on a mechanical and electrostatic system, so that the powder adheres only to the cable.
A wide variety of available powder materials can be used, some of them without the need of explosion-proof measures.
Interlock Armouring Lines
Interlock Strip Armouring machines are used for the production of armored cables and flexible conduits. They are suitable for building cables (MC & AC), ESP cable (Electrical Submersible Pump), data, fiber optic, safety & fire alarm cables.
They represent a low-cost solution for the physical protection of energy, instrumentation, coaxial, data and optical fiber cables.
Cable constructed with strip armouring of aluminum, steel or copper is also known as BX, Interlock or MC cable and offers a combination of high tensile strength, crush and impact resistance making it the preferred choice for demanding installations.
Rigid or Planetary Stranders
Rigid Stranders are cage type machines without backtwist. They are suitable to produce multiple wire combination strands of copper or aluminum for low, medium and high voltage applications, cabling insulated conductors for control cables, screened power cables and steel wire armouring.
Typical lines include the capability to strand 37 or 61 elements in a single pass with tandemizing options to further enhance the line’s capabilities.
Planetary Stranders are cage type machines with backtwist. They minimize the twisting of bare wire/insulated conductors around their own axis by utilizing an eccentric ring principle to maintain the axis of the bobbins parallel as the cage rotates.
These machines are designed in two versions, light duty, for cabling insulated conductors with low bobbin weight, and heavy duty, for stranding bare wire with high bobbin weight.
Single or Double Twist Stranders
Single Twist Stranders are suitable for stranding, cabling and armouring bare or insulated conductors (with or without taping).
Double Twist Strander is an “outside/in” configuration with bow, capstan, take-up, traverse and loading platform.
Depending on the strand construction and number of wires, either a single or double twist strander will be used, in order to optimize the tension and straightness of each conductor.
Roll Form Strander Systems
The Roll Form Strander program covers machines designed to accommodate reels up to 2240 mm. The scope of the products that can be manufactured includes:
Copper and aluminium stranded conductors between 10 mm2 and 300 mm2
The process is capable of manufacturing bunched conductors to compact strand with Fill Factors between 76% and 97%
Aluminium Conductors Steel Reinforced (ACSR) using a single steel wire core
All Aluminium and Aluminium alloy Conductors (AAC & AAAC)
Cabling of insulated conductors
The aim of this system is to shape individual wire of single diameter and present the material to the strander in the optimum format depending on the desired strand construction.
High-speed Twinners
High speed Twinners are ideal for the manufacturing of shielded and unshielded pairs up to 5 mm diameter with a bow speed of up to 2500 rpm and line speeds of up to 600 m/min. A digital drive package ensures precise lay control of the finished pair. This line is suitable to assemble with solid HDPE, FRPE, Foam HDPE and FEP insulations.
The major components of the line include the following:
Dual driven payoff or Backtwist Pay-off for LAN pairs
High Speed Twinner
Machine parameters are digitally monitored and controlled via a Programmable Logic Controller (PLC) and a menu driven touch screen so that at each stage the operator is guided to obtain the desired machine operation.

In both series, the mixer comprises a top-up heating mixer and a cooling mixer at the bottom.
Horizontal Mixers
MTI offers horizontal mixers, such as the Horizontal Cooling Mixer Type K, for the cooling of mixtures. For greater flexibility and variety of products, Horizontal Universal Mixers Type H are suitable, as they are ideal for mixing, dispersing, granulating or coating, heating / cooling and drying of products for virtually all applications and industrial sectors.
Vertical Mixers
MTI offers two types of vertical mixers, the High Speed Mixer Type M, with peripheral speeds of 10 m/s up to 40 m/s, and the Universal Mixer Typ UT UniTec®, with peripheral speeds up to 8 m/s. Both are friction mixers for powder materials with the option of adding liquids and offer a wide variety of processes ranging from heating and tempering by reaction, melting, and coating to agglomeration and dispersion, even under pressure or vacuum.
Mobile Container Mixers
The latest innovation of MTI is the Container Mixer C tecPRO, a robot with mobility in six axes and individual containers of up to 600 l capacity. It allows to make different subsequent mixtures in less time, since it is not necessary to wait for a previous cleaning. In addition, each container can have different tools, as these are not attached to the robot. The flexibility of the robot allows working with containers of different sizes, so you can adapt the production of each mix to the needs and thus achieve maximum productivity.
