Molding Plastic Tank Industry and the Future

Number of visits: Date:2017-08-01
  In recent years, China's rotomolding industry in the continuous development, but there are still problems, due to the continuous popularization of plastic storage tank, plastic storage tank for the existence of the problem should focus on the issue, and then clear the relevant issues for rotational molding Industrial future development trend. Here we have a specific problem and the development direction to do a detailed explanation.
  What is rotomolding (plastic)?
  Rotational molding, also known as plastic, rotary molding, rotary molding, rotary molding, etc., English for RotationalMoulding. Plastic molding process has a variety of methods, in addition to our common injection molding, blow molding, extrusion molding and other processes, the plastic (plastic) is also a plastic or plastic composite products, an important processing methods, especially in the hollow forming Aspect, rotomolding has a more prominent advantage.
  1, the domestic rotomolding plastic tank industry problems
  (1) rotomolding production equipment, the number of small, smaller production scale, upstream and downstream product intensive low.
  (2) lack of research and development capabilities, the lack of their core technology, including technology, equipment and mold manufacturing technology, engineering design and product application development technology.
  (3) category is not fine enough, low added value, poor market competitiveness.
  (4) the lack of reliable, high-quality domestic raw materials, most still rely on imports.
  Rotational molding process is the first plastic raw materials in the form of powder into the mold, and then continue to rotate the mold (three-dimensional movement) and heating the mold, then the plastic mold in the mold under the action of gravity and heat, gradually evenly melt coating On the entire surface of the cavity, after the cooling of the plastic products or steel-plastic composite products that is rotomolding products.
  2, domestic rotomolding plastic tank industry trends and direction
  (1) rotomolding production enterprises continue to expand the scale.
  (2) through the rotomolding product structure adjustment, rotomolding varieties increasing, rotomolding products continue to provide high technological content, rotomolding products will be high performance and high value-added direction.
  (3) to increase the relevant technology, equipment and mold research, to form their own core technology.
  (4) to strengthen the development of domestic rotomolding materials, and the establishment of raw materials research and development centers, completely change the current plastic raw materials mainly rely on imports.
  At present, the foreign rotomolding industry developed rapidly, and domestic due to various factors, rotomolding processing industry development speed is lower than other plastic molding processing industry. Recently, with the increasing understanding of the advantages of rotomoulding, rotomolding industry in the country was to accelerate the development trend.
  3 Rotational plastic storage tank process
  (1) Molten plastic storage tank using rotary molding process.
  (2) The PE plastic storage tank produced by the company is rotomolding material - linear low density polyethylene (LLDPE) or linear medium density polyethylene (LMDPE). PE plastic storage tank can be filled with inorganic acid at room temperature, alkali, salt, most of the material and many organic matter.
  (3) plastic plastic tank plastic used in the minimum softening point of 108 ℃, the maximum fragmentation point of -70 ℃, it is generally used to hold the temperature -40 ℃ to 60 ℃ liquid. If the proportion of liquid filled with heavy or temperature higher than 60 ℃, should be used steel lined with anti-corrosion storage tank to prevent softening deformation of the tank. If the PE plastic tank is used for chemical reaction or dilution, the corresponding test should be done in advance to determine the reaction or dilute the maximum temperature.
  In recent years, with the environmental projects to carry out the hot, the demand for various types of storage tanks increased, and rotomolding plastic tank market mixed with the industry criticized. "We produce rotomolding plastic PE tanks in the same type of product has an irreplaceable advantage!" In the size of the enterprises have to stand, the increasingly fierce competition and the current brutal of his emboldened from where?
  Due to people's awareness and market regulation of the restrictions, so that people for the rotomolding plastic tank price evaluation capacity and so are still very weak, resulting in many customers to buy high or because the price of its discouraged, so be sure to do before buying Ready to work. Although it is a new thing, rotomolding plastic storage tank with its superior performance and reasonable prices will occupy the future market, becoming the new dancers of plastic molding tank industry.
