In today's world economic changes in the plastic bottle industry, which is the structure of the domestic industry is constantly upgrading the state, and in the current process of industrial upgrading, a lot of value-added part of the industry will be To a variety of business problems on the difficult, but also an unprecedented challenge, will face a variety of difficulties, in today's society, plastic products manufacturers gradually occupy the dominant position in the market.

    The development of plastic bottles are faced with a variety of problems, we can give you a careful analysis of the plastic bottles are labor-intensive industries in the current labor costs in the rising, for plastic bottles Of the enterprises in terms of labor costs which have enormous pressure, there is the price of raw materials is constantly rising, but also by the various costs on the market rising for raw material prices is very obvious, and But also to the enterprise to bring another layer of pressure.

    With the debt crisis in Europe as well as the world's economic weakness, plastic bottles of foreign trade orders are gradually declining, many foreign-oriented enterprises are constantly turning to the domestic market, this has been very competitive to bring the plastic bottle market A very large pressure, and the price of the war more and more powerful for the enterprise's profit has become lower and lower.

    Some of the plastic bottle manufacturers, and now all kinds of pressure in the situation, Suzhou blow molding processing is more should take the industrial upgrading of the road, and also need to walk in the field of plastic packaging innovation road, this will continue to improve the plastic bottles Of the added value, and in the production of plastic bottles and the design of all aspects of sales are constantly improving.

There are two main manufacturing methods of plastic packaging bottles, extrusion blow molding and injection blow molding two ways. The main injection molding process of plastic packaging bottles, in the injection molding process, used to mold the main mold of the plastic bottle contains two kinds of male and female mold. Use the injection molding machine to inject the plastic melt into the mold cavity under high pressure. When the mold cavity is opened, be sure to remove the male mold from the female mold and eject the bottle body. The following describes the characteristics of plastic bottle injection blow molding.

    1. Plastic bottles of the melt was injected into the parison mold inside, in the cavity around the inside by the corresponding orientation effect. In addition, the parison blow molding the ambient temperature than the extrusion blow molding temperature is low, in the blow molding process orientation effect can be retained a lot, this phenomenon can improve the overall strength of plastic bottles and other related performance.

    2. Plastic bottles of accurate size and high accuracy, relatively easy to manufacture according to the requirements of the plastic bottles to ensure uniform thickness of the wall, the same specifications.

    3. Plastic packaging bottle surface will not form a joint seam, do not need to be trimmed after molding, under normal circumstances will not produce more than corners, and extrusion blown out of the scrap is generally 5-30%. Plastic bottles have a high degree of gloss, and transparent plastic bottles are used to produce molded plastic bottles that are more transparent.

    4. In the plastic bottle above the blow mold can be designed to slide the bottom of the module, so the flexibility of plastic packaging bottom surface design is relatively large. More suitable for use in the molding of plastic bottles and wide-mouth plastic bottles manufacturing.

    5. In general, the use of injection blow molding plastic bottle most of the volume is relatively small plastic bottles, the shape of the shape of a very complex product, the energy consumption rate will be significantly increased.
