Blow Moulding Industry in India

Although the concept of blow moulding is attributed to the Egyptians during the era of 1700 to 1600 B.C., its process was reportedly first used by the Syrians sometime in the first century B.C. It was the technique of a glass bulb on the end of a blow pipe being shaped into desired hollow forms. 

However, American S T Armstrong is credited to have patented blow moulding technique of a plastic material other than glass in 1851. It was in 1938 that the ultimate industrial application was evolved by the pioneering experiment and work of two inventors, Enoch Ferngren and William Kopitke. Meanwhile, in the mid 1930s, the British company, ICI (Imperial Chemical Industries) formulated low-density polyethylene (LDPE) for the first time that was later commercialised in 1939 and perfected in 1945 for squeeze bottles.

These developments ushered a revolution in the utility of bottles (glass and synthetic-based) as packaging material and today, these have become the common medium for filtered/distilled water, aerated beverages, milk, edible and non-edible oils, cosmetics, medicines (both in solid and liquid formats) and numerous other consumer items. This packing is based on mechanized (automatic) blow moulding machine using PET preform technology. Its impact in terms of growth could be assessed from the fact that the USA witnessed the number of plastic containers for the soft drinks shooting up within a span of 22 years (1977-1999) from a mere zero to ten billion pieces!!

In India several entrepreneurs have made a mark by designing and developing unique models of blow mould systems. These range from PET stretch blow moulding, extrusion blow moulding, reheated stretch blow moulding (RSBM) and injection stretch blow moulding (ISBM) machines among others. These machines boast of different bottling capacities as per the end user’s needs.

Rigid quality control, high standards, competitive prices and delivery alongside prompt after-sales service have lent the Indian manufacturers of automatic moulding machines an edge over their counterparts and competitors from across the world. To cite an example, the machines designed and manufactured by Noida-based Ashish Tools have been found most suitable as an integral part in a wide range of bottling systems including leading brands like the two-stage SBO, Krones Contiform, ASB Nesei, Aoki and several other models, both at home and abroad. With the worldwide acceptance of PET moulding technology as an ideal mode of bottling, the moulding industry in India is poised to reach newer heights in the coming days.

Everything About Plastic Injection Molding

Most products used on an everyday basis never get a thought from a layperson about their making. As a rule, nearly every article is made using plastics, glass, metals and rubbers. However different the material of production may be, the process remains the same – injection molding. Among all such materials of construction, the most common one is plastic.

The evolution of plastic injection molding industry  

At present, close to thirty million tons plastic are manufactured on a day-to-day basis. The significance of plastic as a material for construction is due to its high availability; almost 60,000 variants of this material are manufactured at present.

However, the prosperity of injection molding technique began with the innovation of resins such as Styrene, K Resin and Nylon 6/6. Another factor that propelled the growth of this molding technique was the manufacturing of ultraviolet inhibitors and different additive colors. 

In 1980s, the plastic material was given prominence with the development of horizontal injection molding machinery. With the beginning of high-end vertical mold machines and hybrids molding systems, it became possible to manufacture plastic products with unimaginable contours and tight dimensional tolerances. In the past, the process of molding was daunting and accounted for several injuries. However, the development of technology (such as robotic controls and hydraulics) has helped the process become safer with each passing day.

How plastic molding industry got better?

Notwithstanding the wonders of plastic injection molding, the procedure drew flak from several green revolutionists due to the material it used. However, large shares of revenue and energy are spent to make plastic environmentally more acceptable.

With the fruitful attempts to make plastic recycling possible, the entire process of injection molding has become efficient. The developments of high-strength thermosetting polymers have helped enhance the durability by leaps and bounds. Several pet bottle moulds are made from thermosetting polymers to increase their strength and capacity to withstand high temperature.

Apart from injection molding, one of the most common techniques used for manufacturing hollowed plastic products is blow moulding. Presently, innovative plastics are introduced to make possible impeccable precision and close-tolerances in the final product.

Plastic Bottle Manufacturing Through Blow Molding Techniques

Nowadays, the consumers’ convenience is placed at the highest priority by players belonging to several industries, especially the plastic bottling sector. The plastic bottle manufacturers are leaving no stone unturned to give consumers bottles that are aesthetically pleasing and easy to handle.

In earlier days, the plastic bottle producers had a tough time in shaping the bottles, especially those having complex contours. Even after hard work and dedication, the results were not satisfactory. Such growing frustration urged several plastic bottle producers to take help of technology. After research, a technology finally came up that assisted plastic bottle manufacturers in reducing their everyday manufacturing distresses; the technology came to be known as blow molding.

What is blow molding all about?

The most trusted process for creating plastic containers and hollowed components is blow molding. In blow molding, the plastic is shaped by several processes such as stretching the material, injection or extrusion.  The process gets started by heating and consequently melting the PVC, polythene, or any other plastics before beginning the molding process. The melted plastic has to be transferred to hollowed tubes. Compressed air is used in the hallowed tubes for giving the molten plastic the desired shape.

The blow molding process at a glance

Beginning the blow molding process is no rocket science. The process begins by feeding the plastic granules to the storage compartment. The storage container has motorized threads meant to rotate as well as compartmentalize granules. The compartments (having granules) are subject to extreme heat. Once the granules are melted, they are transferred to the mold. The mold is subjected to intense air pressure, helping the molten plastic to acquire the desired shape.

For experiencing hassle-free blow molding process, purchase a pet blow molding machinery from Ashish Tools. The rich experience of more than two decades has helped the company become an acclaimed destination to get high-class pet bottle moulds. Each of the pet moulds is admired for its dimensional accuracy. Company’s dedication to quality has helped it rank among the trustworthy pet blow moulding machine manufacturers India.
