What Are The Benefits Of Plastic Injection Molding?


Before using a PVC molding machine, it is important to know advantages of using it in your industry. Explore the benefits of such a machine. 

The most reputed PVC Moulding Machine Manufacturers in Kolkata specialize in the manufacturing of the injection molded plastic products ranging from the medical service components and the domestic products to the other products and farm machinery parts. The entire procedure includes melting the polymer plastic granules and then feeding these under extreme pressure into the precision-engineered mold tool cavity. Here the melted plastic cools down and gets hardened to the cavity shape. 

There are several benefits of using this PVC Molding Machine. Here are a few: - 

  • Reduced costs: - Plastic injection molding allows for production in mass on a cost-effective scale. Almost the entire process is controlled by machineries and computerized equipment. The machineries used for this purpose can be managed by one operator only. This cuts down the labour cost or keep it to the least amount. This in turn, lowers the overall investment on the process which finally reduced the cost of the manufacturing parts of the machine.
  • Speed of production: - Plastic injection molding process is a very fast production process. This is another factor that cuts down the cost of the machine. The production cycle times can take up to just a few seconds according to the product that is being melded.
  • Production quality: - At the best manufacturing place, the elements are produced to the most elevated levels of precision. Here, minimum finishing is required. The molds and the machines that are used for plastic injection molding are custom-made. This means that these machines are designed for meeting the exact requirements of every customer while automation. This ensures the reduction of errors at the time of manufacturing and allows close tolerances when the molds are made.
  • Efficient production method: - The plastic injection molding method is highly efficient because negligible amount of the raw materials is wasted or scraped. The plastic or the raw materials that are left after the previous cycle, are recollected, recycled and again melted for use in the next cycle. This allows in optimizing the raw materials. Moreover, this also allows to have a control over the stock.
  • Simplified process: - The plastic injection molding technique has proved to reduce the number of elements needed for manufacturing a product, therefore, reducing the assembling time.

Get To Know About An Automatic Shrink Wrap Machine.

The Automatic Shrink Wrap Machine was invented years ago but with days and advancement of technologies the features and the quality has also updated. Since the invention of this machine there has the requirement to apply heat to get ‘shrink’ as the name signifies. The manufacturers or the workers in the industry need to heat the material quickly and in bulks on the assembly lines. The contemporary and advanced shrink wrap machines vary in terms of size and complexities to handheld the sealers and the heat guns to industrial automation, which can apply that material and heat it in the conveyor-fed oven.

Small Sized Automatic Shrink Wrap Machines

The smaller sized mechanized shrink wrap machines are generally single-purpose devices, which are only part of the process of shrink wrapping.
Sealers: -The sealers are used for clamping pieces of the shrink wrap together and then seal these by heat application. These can also indulge bladed edges for cleanly cutting shrink wrap. These devices come in a broad variety of models ranging from the smaller handheld models to the larger freestanding or tabletop machineries.
Heat Guns: -The heat guns are the handheld devices that are similar to a hairdryer in some respects. These are used for manual shrinking and seal shrink wrapping.
One-Step Systems: -These are somewhat larger in size and are designed for sealing and shrinking the wrap under a single hood and are available in a broad array of dimensions to fit several different boxes.
Shrink Wrap Tunnels: -Available in different sizes, these tunnels are the small conveyor belt fed ovens, which apply heat for tightening the shrink wrap. These small sized shrink wrap machines are suitable for the smaller establishments and manufacturers, which do not make use of shrink wrap for all their merchandise.

Industrial Shrink Wrap Machines

The larger industries and the manufacturers need the large shrink wrap machines. These are usually all-in one mechanized machines, which are capable of tightening and wrapping shrink wrap over almost dozens of packages per minute. Most of the times, the industrial shrink wrap machines are included on assembly line. Exactly what type of shrink wrap machines are preferred and used by the major industries highly depends on the distinct needs and applications of the industries. Most of the PVC moulding machine manufacturers also manufacture the shrink wrapping machines that are packed with the latest features.

Use Shrink Wrap Machine For Automatic Packaging Applications

A shrink wrap machine is broadly used in the industrial applications for the automated packaging processes. Due to the requirement for rapid and more efficient packaging techniques, the shrink wrap machine has updated by including the shrink tunnel and web sealers. 

What are the Operating Principles of the Web Sealer Tunnel/Sleeve Wrapping Machines? 

  • The Shrink Wrapping Machine is used extensively for forming the plastic polymer film all around the item being packaged. The polyolefin wrap that is put all around the item act as the protective material. It is a simple packaging technique and is broadly used in several industrial packaging systems like food, soft drinks, pharmaceuticals, agro chemicals, etc. 
  • Conventionally, the shrink wrap machine was found to have L bar feeders where the operators could fit the plastic polymers. The manual technique is then replaced with the Automatic Shrink Wrap Machine that includes web sealer and shrink tunnel. 
  • The shrink tunnel is now fitted in most of the shrink wrap machines and is an integral part of the packaging process. The tunnel manages and reins the dimensional stability of shrink wrap thus enabling it to accomplish the perfect shape around the product that is packaged. 
  • The shrink tunnel is escalated on the conveyor system with plastic wrap that is loosely hanging on shrink tunnel. The gap between the rollers and the top of the shrink tunnel is warmed to allow the shrink wrap to coil around the item loosely and then seal it. Most of the shrink wraps incorporate diverse cooling and heating mechanisms in order to ensure that the packaging method is effective. 
Processing Capability and Capacity of the Shrink Tunnel Machines:-
  • Early, the shrink wrap machines had the L bar feeders and manual feeds. The procedure was quite slow and could package a few items in a minute. 
  • Due to the requirement for augmented speed, the automated conveyor systems, the shrink tunnel, the heat and air flow controllers and the web sealers have been fitted in most of the shrink wrap machine models. The automatic control and feed enable faster packaging. These machines are capable of packaging approximately 100 products in a minute. 
  • All systems are completely automated and are cautiously controlled using the PLCs and computers. The systems cool and heat the shrink wrap while conveyor system moves the items. The product is ultimately packaged and sealed using web sealer. 
  • The dimensions of the sealed package, cooling and heating time, weight, and the sealing length can be adjusted in order to suit specific application. Most of the machines have the maximum limit on parameters as per the size of the machine. 
Why Web Sealer is Incorporated on the Shrink Tunnel Machines? 
  • Including a web sealer completely automates the packaging technique thus, ensuring that wrap paper and the product are fed into the machine. The shrink wrap along with the web sealer perform functions like shrinking and wrapping the item. 
  • These machines are broadly used in the automated packaging methods where rapid packaging is needed.

Things To Know About An Injection Molding Machine

The array of the most reputed manufacturer and supplier of Turnkey Project Solutions in Kolkata incorporate an injection molding machine too besides the other featured-packed machineries.

Now, What Is An Injection Molding Machine?

An injection molding machine is also known as an injection press. It is used for manufacturing the plastic items by the process of injection molding. The machine has two major parts, a clamping unit and an injection unit.

How The Machine Is Operated?

The molds of the injection molding machine can be fixed firmly in either a vertical position or a horizontal position. Most of the industrial machines are found to have a horizontal orientation. The vertical machines are used mainly in few niche applications like allowing the machine for taking advantage of the gravity and for insert molding. 

Some of the vertical machines do not need the mold to get tied up. There are several techniques of fastening the apparatuses to the platens, manual clamps being the most commonly used ones. However, the magnetic clamps and the hydraulic clamps are also used sometimes for the same purpose. These machineries are used where the fast tool alterations are needed. 

The manufacturer of the Injection Molding Machine selects that whether the mold will work the best if a cold runner system is used or if a hot runner system is used for carrying the plastic directly from the injection unit straight to the cavities. A cold runner is a  straightforward channel that is carved into the machine’s mold. 

The plastic, which fills this type of runner cools down as the portion cools and then it is ejected along with the portion as a spruce. The hot runner system is a bit more knotty, often making the use of cartridge heaters for keeping the plastic in the hot runner as the part cools down. After the ejection of this part, the plastic that is remained in the hot runner is then injected into the subsequent part. 

Features Of A HDPE And PVC Injection Blow Molding Machine: -
  • Double heads, triple heads, four heads, or five heads
  • Zebra Line head having two layers, three layers, or four layers
  • Single or double stations without or with a de-flashing machine in diverse models
  • The bobbling extruders
  • Being able to view the strip machineries
  • Bottom propelling system
  • Angular waft attachment
  • Multi-point controlling system
  • Extruders with larger screw
  • Fitted with the hot wire cutters

Some Usages Of Soda Water Are Here To Be Explored

The soda water also referred to as the seltzer water, sparkling water, fizzy water or the bubbly water is actually the water into which the carbon dioxide gas is dissolved under pressure. Soda water or club soda contains additives like sodium bicarbonate, and sodium chloride but the normal seltzer is composed of only water and carbon dioxide without having any kind of additives. Carbonation is actually the technique that makes the water effervescent. Most of the soda water is sold in the local shops in the ready to drink bottles such as carbonated beverages like the soft drinks. Soda water made in the plants using the advanced Soda Water Plant Machine is of the best quality but nowadays soda water can be made in home also with the latest models of soda makers.

Check out the combined usages of soda water: -

  1. Carbonated beverages: - The plain soda water is regularly consumed as the alternative to the soft drinks. A soft drink is typically a beverage that contains carbonated or soda water, a flavoring agent, and a sweetener. The flavored soda water is available such as the cola. Plain soda water is frequently consumed by mixing it with fruit juices too. But this is totally different in taste as compared to the taste of the flavored ones like lime flavor, lemon, orange, cherry or the raspberry flavors. Many prefer to add diced or chopped fruits in the soda water to enjoy it in a bit different way.
  2. Alcoholic beverages: - Soda water is the liquid solution that can be mixed with the alcoholic beverages in order to top-off the hard drink and add a degree of ‘fizz’ to it. Adding the soda water to the alcoholic drinks like spirits dilutes the solution. Soda water also works really well in the short drinks prepared with brandy, whiskey, and campari. This type of carbonated water is also used for dilution of the drinks depending on cordials like orange squash. The soda water is a vital ingredient in making cocktails too.
  3. Cooking: - Soda water is rising in demand in cooking to give a lighter and fluffy texture to the dough and batters. It is found that the fizzy bubbles when added to the dough make the dough fluffy, light, and soft. Actually, pockets or pores are created on the dough when the soda water is added to it. These pockets get filled with carbon dioxide gas which provides such a texture to the dough.
  4. Stain remover: - It is popularly known that soda water is an excellent stain remover. Stains on clothes like red wines, tea or coffee get easily removed when washed or rubbed with soda water. But there is no underlying reason why soda water is superior to the plain water for removing stains from garments.
There are a number of industries now that provides the best Turnkey Project Solutions in Kolkata, efficient soda water making machine being one of the solutions.

Working Of Corrugated Carton Manufacturing Plant in Kolkata

Most of the items at supermarkets or the discount stores are safely delivered in different sized boxes known as the corrugated cartons made up of the corrugated cardboards. Corrugated cardboard is actually a stiff and firm yet light weighted material made up of three layers a brown kraft paper. These papers are used for corrugated cartons or boxes for delivering such heavy products since these types of papers have the capability to resist splitting, tearing and bursting.

From the paper mills, huge numbers of rolls of kraft papers are seen to be transported to the Corrugated Carton Manufacturing Plant in Kolkata. At the plant, these papers are layered up to form the cardboards and finally to the cardboards are then folded, cut, printed, and glued up to form the cartons or the boxes. At the beginning of this entire process, the kraft rolls are loaded into the giant sized machine called the corrugator. After the cartons are made, batches of these finished cartons are banded together for supplying or shipping to the toy makers, food processing units, automobile parts distributors and many other establishments.

Raw materials: - The fast growing that is the tall pine trees supply the primary raw materials that are used to make the corrugated cardboards. The big packaging industries convert the wood of the trees to the kraft papers. Rolls of the papers are then supplying in massive number to the carton manufacturing plants.

Design: - Today, in a corrugated carton manufacturing plant, designers are appointed who create innovative containers that need four-colour printing and the complex die-cutting techniques. These designs are made using sophisticated software like CAD programs, etc. The designers generate new designs or renovate the existing ones. Many retail stores prefer to use the light weighted and colourful corrugated cartons.  

The manufacturing process: -
  1.  Collecting the manufactured kraft papers from the industries.
  2. Corrugating the cardboard using those kraft papers.
  3. Forming the blanks into the cartons using the corrugated cardboards. The cartons are too made using the corrugators machine.

Quality control: - Quality control starts with the checking of the quality of kraft papers supplied by the packaging industries. The kraft papers have to be smooth and firm. After the papers are passed through the corrugators and transformed into the cartons, individual blanks of the boxes or cartons are pulled from the stack and then tested. The cob test measures the amont of moisture content in the medium and the liner. The glue strength, compression power, bursting resisting strength and the highly accurate tests for the dimensions of the cartons determine the quality of the whole manufacturing process.

Many companies provide different Turnkey Project Solutions in Kolkata. These companies ensure to take care of the projects starting from the conception to the conceptualization.
