Plastics Manufacturers Gradually Dominate The Market

- May 24, 2018 -

 In the process of world economic changes in today's world, the structure of the domestic plastics industry is also in a state of continuous upgrading. In the current process of industrial upgrading, many industries with a certain added value will be affected. Difficulties in all kinds of business operations are unprecedented challenges and will be faced with various difficulties. In today's society, we can talk about plastic bottle companies in the storm of transformation.


    The development of plastic bottles is faced with various problems. We can give everyone a careful analysis. For plastic bottles, which are labor-intensive industries, the current labor cost is rising, for plastic bottles. In terms of companies, the labor costs are enormously stressful, and the price of raw materials is rising constantly. It will also be subject to rising costs on the market. The rise in raw materials is very significant, and It will also put another layer of pressure on the business.


    With the European debt crisis and the world's economic weakness, foreign trade orders for plastic bottles are gradually declining. Many foreign trade companies are constantly turning to the domestic market, which brings to the already highly competitive plastic bottle market. There was a lot of pressure, and the price war was getting worse and worse, and the profits of the enterprises became lower and lower.


    Some of the plastic bottle manufacturers, nowadays in various pressure situations, are even more apt to take the path of industrial upgrading, and also need to take the innovation path in the plastic packaging field, which will continue to increase the added value of plastic bottles. And in the plastic bottle production and design sales in all aspects of continuous improvement.


    There are two main manufacturing methods for plastic bottles: extrusion blow molding and injection blow molding. The main injection molding process for plastic bottles is that during the injection molding process, the main molds used to form plastic bottles include both female and male molds. The injection molding machine is used to inject the plastic melt into the cavity of the mold under high pressure. When the mold cavity is opened, it is necessary to remove the positive mold from the inside of the cavity and eject the bottle body. The following describes the characteristics of injection molding of plastic bottles.


    1. The melt of the plastic bottle is injected into the parison mold, and the orientation effect is received around the inside of the cavity. In addition, the ambient temperature of parison blow molding is lower than that of extrusion blow molding, and the orientation effect generated during the blow molding process can be retained a lot. This phenomenon can improve the overall strength of plastic packaging bottles and other related issues. performance.


    2. The size and size of the plastic bottles are accurate and accurate, and it is easy to ensure that the thickness of the plastic bottle walls is uniform and the specifications are the same according to the manufacturing requirements.


    3. The surface of the plastic bottle will not form a joint seam, and it will not need to be trimmed after molding. Under normal circumstances, there will be no corner material, and the scrap produced by extrusion blow molding is generally 5-30%. The gloss of plastic bottles is relatively high, and the use of transparent polymers to produce molded plastic bottle bottles is more transparent.


    4. The sliding bottom module can be designed on the blow mold of the plastic bottle, so the flexible design of the bottom shape of the plastic package is relatively large. It is more suitable for use in the manufacture of molded printed plastic bottles and wide mouth plastic bottles.


    5. In general, plastic bottles with injection-blow molding are mostly small plastic bottles. For products with very complex shapes, the speed of energy consumption will increase significantly. Manufacturers of plastic products gradually dominate the market. status
