Closure molds: What is the basic process of bottle mold technology?

The difference between plastic and metal is that while the former is cheap, the latter is very expensive. Even though there are various metallic products of different shapes & sizes, they cannot replace plastics. Metals are very expensive and it is not feasible if one begins to use metallic products for all day-to-day activities. For instance, it is not easy to replace plastic PET bottles with metallic ones, since the latter cannot be repurchased on myriad occasions. Bottle mold technology has ensured that high quality PET bottles and other plastic products can be manufactured at a very cheap cost. Cheapness of cost ensures that the consumers can buy them at low prices. That is why these products have found widespread use in our daily lives.

We are encircled by closure molds items. We use them at home and at offices and even in shops and hospitals. Take for instance, the computer you are using now. Its keyboard contains keys which are churned using this technology. Or consider the containers which you carry every day to your office for your lunch. The exact shape of such containers has been rendered possible because of these techniques. In the absence of these techniques, it is impossible to lead the kind of comfortable life we are leading now.

So, how does this technology work? Without going into too many jargons, one can say that the process pretty much comprises of three steps. The first step is to melt the plastics. Plastics are solid in general but at elevated temperatures, they can be liquefied. The second step is to insert the liquefied or molten plastic into a mold. Now, here one must say that the mold is like a vessel of a specific shape. The aim to make the plastic acquire the shape of the mold! So, a bottle mold is used when the objective is to manufacture PET bottles.

The third step involves the reshaping of the molten plastic followed by cooling. Once the molten material is inserted into the closure molds, it will automatically take the shape of its container. Thereafter, the temperature is reduced drastically and the entire thing is cooled or frozen. After the freezing process is over, the final product can be safely taken out. This is the basic synopsis of how the technique works. Of course, there are other technicalities involved but they are beyond the comprehension of a layman. This primarily is a first-hand account of how the manufacturers produce mold products.

This process of bottle mold can be carried out with expedience and economy. That is to say, the producers make sure that less time is spent for the process and even the cost incurred is significantly lower. With the evolution of technology, it has now become possible to bring down the cost and the time invested in the manufacturing of plastics. 

Closure molds have also helped in development of custom-made items. So, if a particular firm requires products in a unique way, it can always make the mold in that shape. The process also ensures uniformity of all items.
