How to select and purchase plate rolling machine

Company owners should continuously renew their fabrication apparatus as well as control its productivity to be able to stand the competitive market requirements. This will help them to avoid such situations as order reduction, staff cost increase and low profits. So prior to obtaining a plate roll machine, business owners should make careful considerations on its cost and capacity as well. Unless it appears not so effective as the old machine, there will be no point in investing. The purchase more often may not worth the cost paid for it and may not correspond to proper productivity standards and requirements.

Being a leading plate roll equipment producer, Artizono has summed up its last thirty-year practice in these 5 guidance tips on plate roll machine purchase. Now let us look into them.

Material impact on plate rolling.

Metal stuff is a major factor in designing sheet-roll equipment. For instance plates possessing high yielding force produce higher pressure while being rolled by the machine. This has to be taken into consideration, otherwise the plate gets distorted near corners bringing to imperfection. Nowadays steel force is stronger than ever, so demands on roll equipment pressure endurance are stricter. There are some specified standards according to which steels can be classified. Each steel type has its roll pressure. Material fragility, yielding force and plate usage are defined as major coefficients to be considered by rolling equipment manufacturers.

Cooperation with sheet rolling machine manufacturers ready to discuss details.

All companies have their particular needs. They have to decide on what products they are to roll conic or parabolic, then come into markets. CNC sheet rolling bend equipment with rough top and bottom rollers is the most suitable to roll these kinds of plates. This kind of sheet roll equipment is advantageous as it efficiently eliminates metal sheet face wearing, meanwhile removing edges of cone tips while polish processing. Artizono has come to the conclusion that the theoretic balancing that is provided by CNC system may not be always efficient, but the exact conic roll can be gained through torque balancing. Accurate balancing ensures perfect tapering of the plate within five seconds. Besides, suppliers should make such details as diameters, materials, errors, shapes apparent to purchasers. For instance, in production process often arise roundness errors of no more than 1 percent diameter. If sheet roll equipment power is not sufficiently proper, some kind of cylinder phenomena happen bringing on production incompetence. Buyers` demands should be taken into consideration by sheet roller equipment manufacturers.

Choice making in accordance with proper conditions.

Companies should define which material and thickness is suitable to lead them to better profits. Plate roll equipment manufacturers must consider the mentioned specifications to devise and produce appropriate rolling bend equipment. This is time saving as well as effort reducing. Practice has shown that leading sheet roll machines in general function most effectively when half-loaded of their complete capacity. For instance, a sheet roller with capacity of processing materials of 10 mm thickness makes its best performance when rolling 5 mm thick sheet.

A common trouble connected with sheet roller equipment functioning can be plate sizes as well as the bottom and top roller pressure. In case a plate rolling equipment with rolling capacity of 10 mm thickness rolls 6 mm thick sheets, a particular cylindrical deformity may happen leading to serious problems. However, even a bigger problem may occur when material thickness comes to the rolling equipment limits. Usage of gaskets will allow the equipment being controlled. In case a roller machine designed for thick plates is used to roll slim plates, the central area of plate appears stronger compared to its surrounding ones. This trouble can be solved by using gaskets to correct deformity.

Proper consideration on sheet thickness and diameters.

The less the diameter, the bigger is the roll pressure requirement. While processing thick sheet of little diameter, note the top roller location and roller machine framework, as they are the major coefficients influencing opening sizes. Nearly every sheet roller is devised with top roller utmost rolling diameter of as much as 1.5 times. In this particular condition the utmost inside diameter of roll process with 50 mm top rolling may be of 75 mm.  Completely new technologies allow almost half of the sheet be exposed to pressure while being bent and diameter effectiveness increases up to 30 percent. Note that the most perfect accuracy roll level that a plate roller equipment is able to provide is half of its designed standards.

Coordinating of horizontal and upright supporting strengths.

This can be greatly beneficial in terms of labor scale and efforts, and the work may be implemented by a person instead of more. In the process of cylinder product roll, if the diameter 200 times exceeds the sheet density, sheet gets bent owing to its own heft. The perfect diameter is impossible to gain with no support. Buying a plate roller with supportive materials, solves this problem. Sometimes there may be a manufacturer who makes use of a forklift or crane for cost reductions, though it often brings on the machine scopes limitation.


Most customers are inclined to disregard a set of major coefficients bringing on improper machine purchase, which in its turn causes troubles in further production process. So, the major tips mentioned above will surely be useful for sheet roller equipment purchasers.
