One of the most modern methods for producing plastic products today is that of blow molding. Blow molding is a polymer production process widely used to produce plastic parts, such as plastic bottles, plastic tubes and storage containers. Blow molding allows businesses to mass Produce plastic items very quickly and efficiently. In addition, it is also considered one of the safest process for producing high quality plastic products. The following article will provide a detailed overview of blow molding and discuss some of the important benefits of this process:
- Simplifies production processes. With a blow mold, manufacturers can produce the necessary plastic parts or containers in a shorter time than conventional mould making. When using a preform mould, it takes a longer time to manufacture the exact shape of the desired part; therefore it is quite expensive. Blow molds make it possible to manufacture the required hollow object in an economical way since it does not require using a cold or hot preform mould.
- High quality output. With the help of injection moulding, manufacturers can obtain a consistent volume of identical products from a single mold. Blow moulding also helps in increasing the production efficiency by reducing the time needed for the injection process and also increasing the production levels. Moreover, the increased production levels translate into high quality bottles that can withstand extreme conditions.
- Increased flexibility. In injection moulding, the plastic-filling material (polyethylene) can be manipulated at high temperatures which enables the filling of the product with liquid ingredients. The high flexibility of the product also allows the manufacturing of smooth rounded objects, which can be ejected from the bottle easily without any difficulty.
- Higher quality control. Through the help of injection moulds, manufacturers are able to produce fine details and precise shapes on the bottles that can add to their durability. The accuracy of the manufacturing process is also increased because the plastic is evenly melted at the heating process. Thus, the production of smooth round objects is greatly increased with the use of blow moulds. Apart from quality control, manufacturers are also able to meet increasing customer demands by offering different varieties in the designs of their containers. Moreover, the containers can also be designed to specific requirements of the customers.
- Improved stability. In the production of bottles under pressure, it is necessary that the preforms are firmly and properly installed so that they can remain rigid during the whole manufacturing process. In case of preforms, the manufacturing companies can ensure that preform wall thicknesses are maintained to the required levels, thereby contributing to superior quality as well as consistency in the finished product. Furthermore, the preformed bottles with preform walls that are made using the blow moulding techniques have high strength and endurance levels.
- Reduced waste. During the production of bottles, it is possible that some of the ingredients might leak out and spill. When such containers are used for storing liquids, it is necessary to recover them quickly before the product starts showing signs of wear and tear. For this purpose, the bottles with preform walls can be used, which feature a thicker wall thickness. As a result, the waste products formed during storage are reduced and the production time for refills is shortened. In addition, the bottles with preform wall thickness can reduce the total number of waste products used during the manufacturing process and this results in overall cost savings as well.
