How is the plastic pallet manufacturing process? Do you use plastic pallets in your company? If your answer is yes, I'm sure you've already asked yourself: What will the plastic pallets manufacture in India process be like? Over time, the plastic pallets manufacture process has evolved with changes in the behavior of companies and the market, and of course technological developments have had a strong influence on this manufacturing modernization. The objective of the process is to optimize the parts, that is, to improve their thickness and structure, reduce their weight, increase their durability and manufacture increasingly sophisticated designs. There are several techniques to plastic pallets manufacture, to the point that sometimes it is difficult to choose the process that can increase the efficiency of the supply chain within our company. Among the most common manufacturing processes that we can find today, the following stand out: injection, thermoforming, blowing, compression and rotational molding. We will focus on the manufacturing process of plastic pallets produced through the injection system, as this is the technique that we use at Inplastic, as we believe that it is a system that aims to guarantee the quality of all products and fulfills one of the values that more defines us and matters: sustainability and care for the environment, making it possible to recycle solid waste, Stages of the injection molding technique for plastic pallets Making plastic pallets by injection is one of the most used processes to give this material the desired shape and size. It is the perfect technique when you want to carry out a large-scale production, especially when you need the same pallet design to be produced in a high number of times and to remain stable and equal over time. In general, the injection process goes through the following manufacturing stages: 1st Step: The plastic is introduced into the machines through a hopper. 2nd Step: The heating bands and friction force melt the plastic material. 3rd Step: The hot plastic, when in its liquid state, leaves the heating chamber through a nozzle towards a cavity or a mold, where the plastic pallet will take the shape of the mold that is loaded, to later cool down and harde through a cooling system. Types of injection systems
Within the manufacturing process of plastic pallets by injection, there are, in turn, two different types or techniques of production that consist of: a low pressure system and a high pressure system. Do you want to know how each one is characterized and what are its advantages? Low pressure system: In this case, the mold cavity is injected with the plastic material of the pallet and an inert gas. Therefore, it introduces a gas that does not chemically react with the material. Carbon dioxide or nitrogen is commonly used, and when the mixture of nitrogen gas and polypropylene/polyethylene is heated, the blowing agents are activated, resulting in a cellular nucleus surrounded by a rigid plastic material. High pressure injection molding: The high pressure injection system is a process widely used in the manufacture of high density polyethylene or polypropylene (PP) plastic pallets. It is a very precise process that does not require further treatment or a high gloss finish. With this manufacturing technique, the raw material is heated inside a barrel that has a rotating screw at a temperature of approximately 250 degrees centigrade. After the plastic reaches the desired temperature, it is injected into a mold, where it is held under pressure and then allowed to cool and expel. Therefore, the high pressure injection molding process is an ideal option when you need a plastic pallet with very intricate details. Both high pressure and low pressure injection systems play a key role in the manufacture of plastic pallets. Over the last few years, the trend in the plastic injection sector has evolved towards a quieter, less bulky, faster machinery, with a lower environmental impact and a more contained hydraulic and energy consumption.
