Rotomoulding is a moulding process for creating many kinds of hollow items, usually out of plastic. It is often done at high-temperature, in a low-pressure plastic using heat and biaxial rotation to produce hollow in the required shape and specification.
Rotational moulding initiated a new age of thinking in the plastic industry, inspiring designs that would have been impossible with conventional manufacturing methods. Apart from the design advantage, the materials used in the production process are eco-friendly and 100% recyclable.
There are many advantages associated with rotational moulding. First and foremost, the moulds are relatively cheap and simple primarily because of the low pressure process and can also be used for complicated requirement as well.
There are several types of rotomoulding machine available in the market. Below is a brief description.
Rock and roll machine
It is a specialized single arm machine. It functions by rotating the mould by 360 degrees in one direction and tipping it around 45 degrees above or below horizontal in the other direction. Such types of machines save the heating costs because of their smaller heating chambers.
Vertical rotational machine
Vertical rotational molding machines have a compact heating and cooling chamber which makes them energy efficient. Even though these machines have a similar capability, like those of horizontal carousel multi-arm machines, they take up a lesser space.
Swing arm machine
This one moves the mould back and forth between the heating and cooling chambers and is a single arm machine. This is a cost effective option mostly used by schools or in prototyping.
Carousel machine
These are the most common rotomoulding machines used within the industry. It is known to have up to 6 arms and comes in a wide range of sizes for multiple heating and thickness requirements.
Critics argue that rotomoulding machine's long cycle time (which is usually only one or two cycles an hour) is a high disadvantage, whereas other moulding machines like injection moulding machines can mould an object in a matter of seconds.
The one who advocates the use of rotomoulding machine say that process does have distinct advantages specially in instances which require manufacturing large hollow parts such as oil tanks etc.
As the industrial sector is growing by leaps and bounds the demand for rotomoulding machines is growing at a rapid pace. The rotomoulding machine suppliers are delighted with the current boom and are anticipating higher profits by the year end.

Rotogravure, more commonly known as roto or gravure among printing industry professionals is a process of printing which involves engraving or transferring an image onto an image carrier with the help of an rotational printing press. Rotary gravure presses are known to be the the fastest and widest presses in operational in modern times, capable of printing almost everything, right from narrow labels to wide rolls of vinyl flooring.
The Process of Rotogravure
This modern type of intaglio printing utilizes copper coated cylinders as the image carriers, on which the desired image is embossed as a collection of small cells. The cylinders are then made to rotate in an ink fountain to let the cells absorbs all the ink that it can. The excess ink is generally eliminated or being scraped from the non-image areas by employing a blade made of steel, rubber or plastic which is called the doctor blade. Webs of paper are made to pass between the cylinder and a rubber-coated impression roller and the ink is transferred by a combination of capillary action and the pressure of the substrate into the engraved cells of the cylinder, helped by the rubber surface of the impression roller.
In Rotogravure Printing Machinery, there are usually three methods of photoengraving that are used to engrave gravure cylinders, where the cell open size or the depth of cells can be uniform or variable.
They are:
1.Conventional with uniform cell size and variable cell depth
2."Two positive" or "Lateral hard dot" with variable cell size and variable cell depth
3.Direct transfer with variable cell size and uniform cell depth.
A wide variety of operations are involved in Rotogravure printing processes such as saddle stitching facilities for magazine and brochure work which may be in-lined with Rotogravure printing process. This process requires efficient Rotogravure Printing machinery as it is widely used for commercial printing of magazines, postcards, and corrugated (cardboard) product packaging.
Enlisted below are a few key features which are generally associated for effluent functioning of the entire Rotogravure printing process :
1.Highly efficient machines featuring options of front & reverse printing facility.
2.The machine should be designed & constructed to meet high standards of flexible printing
3.The drying system of the Rotogravure Printing Machinery should be designed to match highspeed printing by providing hot air dryers with heaters & blowers.
4.The machine should be provided with compact web path, high performance & low waste.
5.The machine should be provided with double job facility at a time with optional & additional arrangement.

Embroidery to a cloth is like a jewellery to a women - Anonymous
Embroidery designs are back and so is the demand for embroidery machines.The ever increasing demand of embroidered fabrics is fast out pacing the availability of embroidery machines much to the delight of embroidery machine suppliers.
Experts insist that this could be the best ever time for embroidery machine suppliers to break even or post record profits as the demand is surging like never before. Even analysts say that a quick look around any store or shop will reveal the growing popularity of embroidery specially in fashion clothes, bags and nearly all accessories. It's becoming one of the most preferable methods of styling a fabric at extremely competitive prices.
One of the reasons embroidery is making a comeback is because of the easy availability of highly advanced and sophisticated embroidery machines which help customize almost any kind of fabric with the best of finishing touches. Industry insiders reveal, this has also been made possible due to the implementation of advanced computerized control on present day embroidery machines.
Embroidery machines are available for both domestic and commercial usage. For this reason, potential buyers need to carry out an extensive research about the prices, features and other options before taking a final call . Embroidery machine prices tend to vary a lot as they are highly dependent on the brand, size and the type of functionality desired.
Embroidery machines can mainly be classified into three types viz. Mechanical, Electronic and Computerized.
Quite understandably, a mechanical machine is operated manually, while an electronic machine make use of electricity. Computerized embroidered machines make use of computer software generated pre-programmed designs that load directly into the machine. Needless to day, mechanical models consume more time and are slowly getting replaced by computerized models which generate highly sophisticated designs in a short period of time over a large collection of fabrics.
These machines comes in various sizes and have ability to execute complex functionalities. Most of the suppliers target bigger companies for highly advanced machines as it reduces their production time, labour cost and gradually make them profitable by delivering a better ROI.
As the textile machinery market is growing by leaps and bounds, it is expected that embroidery machine suppliers will be able to make a killing and make 2011 as one of their most profitable year ever.
