Versatile hot melt coating machine that reduces overhead cost

As you know, adhesive tape is commonly used in every office, business house and industry and even in homes.  This tape contains adhesive or glue which is coated on its surface by using a special technique. The glue is applied by pre-melting the tape and then forcing the tape to cool and thereby allowing the tape and the glue to solidify to the required thickness. This process is done by using a unique hot melt coating roller. Now, one of the manufacturers has introduced a hot metal roller which is capable of applying hot metal adhesives even on Polystyrene (EPS).  The versatile application of this machinery is that it can even roll the materials already coated with adhesive and then heat the adhesive to the required level, and thereby it activates the adhesive.

Wider industrial application:

The hot melt coating has wider industrial application, like, for example, automobile, packaging, construction, textiles, graphic arts and so on. For example, the scratch proof lamination tiles in your drawing room have a coating of exclusive adhesive. This adhesive has been applied by use of exclusive hot melt coating rollermachine.

Process of extrusion coating:

Extrusion coating is one of the important processes of hot melt coating roller technology. In this process, molten resin or adhesive is applied on the surface of the material. The adhesive materials can be applied on paper, polyethylene, aluminum foil, paper board, corrugated board, plastic films and so on.

The mechanism of heating and cooling:

Interestingly, in this technology, the resin is heated up to 320-degree centigrade and then it is applied on the surface of the object. Then the object is passed through a unique chrome plated cooling chamber. This machine forces the object to cool and thereby the resin solidifies to the required thickness.

Other applications:

The utility of roll coaters is not limited to applying adhesives on tapes. It can also be effectively used for applying adhesives to paint, varnish, oil several other products. Further, while applying hot melt you can also manage the thickness of the coating. Thereby, it helps you to effectively manage the viscosity of the coating.

Role of rollers:

In any hot melt equipment, the rollers play a key role. This is because the rollers prevent wrinkles being formed while applying the hot melt. It also laminates the plastic and even flattens the coiled steel. Some of the designs of hot melt machines have rollers which can heat the materials up to 400-degree centigrade and also cool the material to nearly freezing point.

Reduce overhead cost:

In the traditional adhesive technology, water and solvents were being used for coating the adhesive on the surface of the material and thereby it was contaminating the water. But, the hot melt PUR is environmentally friendly because it does not use water at all. The hot roller which is a part of the coating machine eliminates the necessity of separate dryer. This machine has simplified the entire procedure of applying coating on the surface and thereby it has helped in reducing the overhead cost.

Enhanced industrial application:

Considering the importance of hot melt coating machine in this industrial world, it is but necessary that you buy the machines from reputed manufacturers like the http://www.meler.eu. Such manufacturers have introduced several versatile machines having greater industrial application. For more details, just visit http://www.meler.eu/products/special-projects/coating-roller/

Tips for Choosing Crushing and Screening Equipment

Precision crushing and screening equipment can be put to diverse uses in mines, demolition jobs as well as the clearing of the landfills. They are also used by a wide variety of businesses ranging from the largest of mining companies to small startups. When hiring your precision crushing and screening equipment, it is always good to do with a company that is reliable, professional and which has equipment which are well-maintained. The company needs to have professional and expert operators on hand just in case you are looking for wet hire services.

Crushing and ScreeningLook for a trusted name that you can count on to assure you of a high-quality machinery as well as labor hire. The best companies are generally those which have serviced the mining industry for a very long duration of time and which have the expertise in-house in order to streamline your projects and efficiently deliver on your plans and projects.

The precision crushing and screening company that you contract should be one that is capable of working with various sizes of the companies in diverse industries. A good company that has the right qualifications will save you not just time but also money when it comes to the crushing and screening jobs. Machinery should be working and well-maintained and the company must have skilled and knowledgeable labor force. There are certain equipment hire businesses that will generally guarantee you a personalized service with relatively low overheads. Here are additional tips that you can look at when it comes to the crushing and screening equipment hire:

Look for Tried and Tested Brands

When it comes to heavy equipment hire, it pays to work with a company that has some of the leading trusted brands such as Hitachi, Crown, Volvo and Bell. These companies have been in the industry for such a long time and over that time, they had the time to refine and fine-tune their machinery in order to deliver the best results for customers.

Level of Expertise

This matters a lot especially when it comes to wet equipment hire. Does the company have trained, certified and experienced staff? How well acquainted are the staff with the machines?

Insurance and Guarantees

Never hire a heavy equipment from a company that is not insured. Check also if the company offers any service guarantees for its crushing and screening equipment. This is just to ensure that you have your back adequately covered when you are hiring your equipment.

Search

Do not settle for just one company. Search online from various Australian mining equipment rental portals in order to see where you are likely to get the best value for your money. There are sites where you can carry out price comparisons and even place order for mining equipment.

What are the Company’s Strong Points

Before hiring equipment from an equipment rental provider, ensure you evaluate some of the company’s strong points in comparison to other players in the industry. Look at its service advantages. For example, what wet and dry hire options does it have? Are its machines fully insured? Has the equipment been tested for safety as well as efficiency? What level of support is the company offering?
