High Speed Slitting Line

iTOKO high speed Slitting Line is used to create multiple widths or “mults” from a wider master coil. The mults are made from predetermined widths. The slitter consists of three main parts: an uncoiler, slitter, and recoiler. The material is fed from the uncoiler, through the nip between the two circular cutting wheels (one on top and another underneath), and then re-wound in slit mults on the recoiler. The slitting process has been referred to as part art and part science. It is important that the equipment supplier and end user work in concert so the proper components, arbor size, tooling package, horsepower and tensions are suitable for the material to be slit.

We are a leading manufacture in the industry with high speed slitting, automatic coil feeds and hands free coiling. Used for cutting narrow coil strips from main coils, our machinery comes in many widths and thickness and processes at speeds up to 280m/min.

The process begins with loading a steel coil or master coil onto the uncoiler. The uncoiler can be a dual cone type for heavy gauges or a single end expanding mandrel type for heavy or light gauges. The coil can be loaded into the cones via a pusher type ramp or via a turnstyle and coil car that threads the mandrel of the single end into the inner diameter of the master coil. The hold down presses onto the outside diameter of the master coil and the bands are cut on the master coil. The coil is rotated off the cones or mandrel and peeled to allow the head of the coil to enter edge guides prior to the flattener and leveler (if flatness is critical in downstream operations). Next, The slitter, which consists of two parallel arbors mounted with rotary cutting knives.

High Speed Cut to Length Line
iTOKO Cut to Length "CTL" lines  are used for processing coiled metals into precise length pieces for resale or further processing. Cut-to-length lines typically incorporate a number of machines to provide value added services while processing coil to piece.

Light gauge cut-to-length lines are typically for processing material thickness up to 1.5MM while heavy gauge cut-to-length lines can be used for processing materials thickness up to 25MM or more thicker.

Metal cut to length lines typically have relatively tight tolerances on overall piece cut lengths. As with most metal processing, the industry standards that govern these tolerance according to AISI (American Iron and Steel Institute), API (American Petroleum Institue), JIS (Japanese Industrial Standards), GB (China National Standards) etc.

Element machinery has supplied cut-to-length lines handlin up to g thickness from 0.12MM up to thickness 25MM, and strip widths from narrow strip 100MM up to 2500MM

Tube or Pipe Mill
ERW (Electrical Resistance Welding) pipes are manufactured by cold forming of steel coil into a round cylindrical shape are used in various engineering purposes.Tube mills produce pipe and tube by taking a continuous strip of material and continuously rollforming until the edges of the strip meet together at a weld station. At this point the welding process melts and fuses the edges of the tube together and the material exits the weld station as welded tube. Basic components include an uncoiler, straightener, shear, forming section, fin pass section, welder, ID and/or OD scarfing, sizing section, cut off and stacker or runout table.

Each pass in the various sections are made up of a upper and lower shaft that contains roller die tooling which forms the steel strip gradually into a round shape or square if it is a form square / weld square type of mill. This gradual shaping process is commonly referred to as the flower arrangement. iTOKO can provide you a turn-key solution for all your New, remanufactured and used tube mill needs.

A tube mill it's normally consist of the following components: 1)Forming section (Entry guides, Breakdown passes, Fin passes);2)Welding section; 3)Sizing section; 4)Cut-off section.
