From the trend of market development, the production of many blow molding products such as plastic bottles, plastic drums, auto parts and industrial blow molding products has become more large-scale, and various large, medium and small high-speed, stable, energy-saving and auxiliary equipments have been specialized. The perfect and fully automatic extrusion blow molding production line will be the mainstream of the extrusion blow molding industry in the next few years.
Large, super large extrusion blow molding production line
1. Large blow molding tray extrusion blow molding production line
The rapid development of logistics, food, fertilizer, petrochemical, household chemicals, railway transportation and warehousing, pharmaceutical and feed, beer, beverage and other industries will certainly drive the rapid development of the pallet manufacturing industry, especially the blow molding tray manufacturing industry. In recent years, although the injection molding tray industry has achieved considerable development, due to the limitations of the plastic raw materials of injection molding trays and the principle of injection molding equipment, the service life is short and easy to break under the conditions of large ambient temperature difference and high strength and frequent use. . The high-strength blow molding tray has the advantages of high impact strength and durability, and is listed as the first choice for plastic pallets. Its annual market demand is about 20%, while the annual production capacity of domestic high-strength blow molding trays is basically 100. Within 10,000 blocks, it is far from meeting the needs of the market. At present, most large-scale extrusion blow molding machines in China are mainly used in general-purpose models, which are used for the production of 1000L IBC tanks and for the production of blow molding trays, and the equipment capacity cannot be fully utilized. To this end, it is one of the main directions of some enterprises in the industry to intensify efforts to develop high-speed production lines for large-scale and super-large extrusion blow molding machines specializing in the production of blow molding trays.
2. Large-scale IBC Tank extrusion blow molding production line.
There are already a number of extrusion blow molding machine manufacturers in China that can manufacture 1000L IBC Tank production equipment, but most of them are general equipment. At present, China’s 1000L extrusion blow molding machine adopts fewer radial wall thickness control devices for parisons, resulting in uneven control of wall thickness at the four corners of the product, increased consumption of raw materials, affecting the performance of blow molding equipment, and is worthy of causing large extrusion. Blow molding machine manufacturers pay great attention to it.
3. Other large extrusion blow molding production line.
China is a country with a variety of climatic and environmental conditions. The water storage tanks with different requirements have a large market demand. Therefore, the development of a super-large extrusion blow molding production line that is more suitable for the product market is also one of the development directions. In recent years, some large-scale blow molding products manufacturers have jointly developed equipment for the production of special water storage tanks, and their product volume has reached 10,000L.
Multi-layer extrusion blow molding production line
1. Automobile multi-layer plastic fuel tank extrusion blow molding production line.
Multi-layer plastic fuel tank large extrusion blow molding production line has made great achievements in replacing relevant imported equipment. If the production line uses the domestic flexible radial control system to radially control the wall thickness of the plastic parison, the technical level of the equipment will reach a higher level.
2. Multi-layer three-dimensional extrusion blow molding production line.
At present, China’s extrusion blow molding machine manufacturers already have the design and manufacturing capabilities of multi-layer three-dimensional hollow molding units, but since the domestic market has not yet formed a huge market demand, the development of this technology is relatively slow. The development and upgrading of the domestic car industry will boost the development of such units.
3. Multi-layer daily chemical product packaging, plastic barrels, plastic bottle extrusion blow molding production line.
It is expected that in the next few years, multi-layer extrusion blow molding production lines for plastic drums and plastic bottles will speed up the pace of research and development, and will pay special attention to mold matching, automatic deflashing, automatic labeling, fully automatic testing and fully automatic packaging. Research provides equipment and technical support for operators of blow molding products to further reduce production lines.
4, 200 liters of chemical barrel double-layer large extrusion blow molding production line.
In order to meet the needs of large-scale blow molding products manufacturers at home and abroad, domestic extrusion blow molding production enterprises will strengthen the research and development of double-layer, three-layer and multi-layer large-scale hollow molding units, high-speed production, high energy saving, uniform wall thickness, and plastic saving. Raw materials, long-term stable operation will be one of the main research and development priorities of such equipment.
Other special extrusion blow molding production line
The development of extrusion blow molding lines for special blow molding functions requires close cooperation between blow molding manufacturers and equipment manufacturers. It is expected that some special blow molding products in the automobile and motorcycle industries, such as extrusion blow molding production lines of various plastic composite extrusion blow molding tubes, will gain technological breakthroughs in the next few years and be recognized by relevant blow molding products manufacturers.
All-electric extrusion blow molding prodcution line
In recent years, the all-electric extrusion blow molding line has great advantages in the clean production and energy saving of blow molding products, and its research and development progress is relatively fast.
For some blow molding production plants that require a high degree of cleanliness, the all-electric extrusion blow molding line will be one of the preferred options. The current large all-electric extrusion blow molding line is relatively rare. With the increase in the requirements for the clean production of some large and medium-sized plastic drums, the development of large and medium-sized all-electric extrusion blow molding lines will likely accelerate. At present, the general all-electric extrusion blow molding production line is mainly used in some high-end blow molding products industries and industries that require high-clean production. As the equipment manufacturing cost is further reduced, it may be promoted to other blow molding products industries.
