From the development trend of domestic and foreign markets, due to the large-scale production of many blow-molded products such as plastic bottles, plastic barrels, auto parts and industrial blow-molded parts, various large, medium and small high-speed, stable, energy-saving, auxiliary machines A complete set of specialized and fully automatic production lines will be the mainstream development of the hollow board blow molding industry in the next few years.

1. Large and ultra-large hollow plate forming unit and production line

The rapid development of logistics, food, fertilizer, petrochemical, daily chemical, railway transportation and warehousing, pharmaceuticals and feed, beer, beverages and other industries will definitely drive the rapid development of pallet manufacturing, especially blow molding pallet manufacturing . In recent years, although the injection pallet industry has made considerable progress, due to the inherent limitations of the plastic raw materials and the molding mechanism of the injection pallet, under the conditions of large temperature difference in the use environment and high-strength frequent use, the service life is short and easy to drop. The block is broken. High-strength blow-molded pallets have the advantages of high impact strength and durability, and are listed as the first choice for plastic pallets. The annual growth rate of market demand is about 20%, while the annual production capacity of domestic high-strength blow-molded pallets is basically 100 Less than 10,000 yuan, far from meeting the needs of the market. At present, most large-scale hollow board machines in China are mainly general-purpose models, which are used for the production of 1000LIBC plastic barrels and blow-molded pallets, and the equipment capacity cannot be fully utilized. To this end, intensifying efforts to develop large and super-large hollow plate forming units and high-speed production lines specializing in the production of blow-molded pallets is one of the main directions of some enterprises in the industry.

There are already many hollow plate forming machine manufacturers in China that can manufacture 1000LIBC plastic barrels, but most of them are general-purpose equipment. The current domestic 1000L hollow plate forming machine adopts fewer plastic parison wall thickness radial control devices, resulting in uneven wall thickness control at the four corners of the product, increased raw material consumption, and affecting the performance of the forming equipment. It is worthy of causing domestic large-scale hollow plates. Molding machine manufacturers attach great importance to it.

Other large hollow plate forming machines. China is a country with a variety of climatic and environmental conditions. There is a large market demand for water storage tanks and water storage tanks with different usage requirements. Therefore, the development of ultra-large hollow plate forming machines that are more suitable for product market needs is also the direction of development. One. In recent years, some large-scale blow molding product manufacturers have combined equipment manufacturers to research and develop special water storage tanks and water storage tank production equipment. The product volume has reached 2000L. For example, the large-scale water storage tank production equipment designed and manufactured by Weifang Huayu Plastic Machinery Co., Ltd. has been relatively mature.

2. Multilayer hollow board forming unit, production line

Automobile multilayer plastic fuel tank production equipment. The SCJ-500×6 multi-layer plastic fuel tank large-scale hollow plate forming unit developed by Qinchuan Development has made significant achievements in replacing related imported equipment. If the unit adopts a domestically-made flexible curved ring radial control system to radially control the wall thickness of the plastic parison, the technical level of the equipment will reach a higher level.

Multi-layer three-dimensional hollow board forming unit. At present, domestic hollow plate forming machine manufacturers already have the design and manufacturing capabilities of multi-layer three-dimensional hollow plate forming units, but because there is no huge market demand for this in China, the research and development of this technology is relatively slow. The development and upgrading of the domestic car industry will boost the research and development of such units.

The design and manufacturing technology of multi-layer daily chemical product packaging plastic barrels and plastic bottle hollow board forming machines have been mastered by many companies, such as Hong Kong Akei Group Guangdong Kaiping Plastic Machinery Factory, Suzhou Tongda. It is expected that in the next few years, the production line of plastic barrels and plastic bottles multilayer hollow board forming machines will accelerate the pace of research and development. Special attention will be paid to mold matching, automatic flash removal, automatic labeling, automatic detection and automatic packaging. Research to provide equipment and technical support for blow molding manufacturers to further reduce the number of operators on the production line.

Multi-layer chemical plastic barrel hollow board forming unit. The SCJ-230×2 double-layer large-scale hollow plate forming unit designed and manufactured by Qinchuan Development is mainly used to produce 200L series double-layer plastic barrels, which occupies a large share in China. In order to meet the needs of large blow-molded product manufacturers at home and abroad, domestic hollow board forming machine manufacturers will strengthen the research and development of double-layer, three-layer and multi-layer large-scale hollow board forming units, high-speed production, high energy saving, uniform wall thickness, and economical Plastic raw materials, long-term stable operation will be one of the main research and development focuses of this type of equipment.

3. Other special blow molding hollow board forming units

The research and development of the hollow plate forming unit with special blow molding function requires close cooperation between blow molding product manufacturers and equipment manufacturers. It is expected that some special blow-molded products in the automobile and motorcycle industries, such as the hollow plate forming unit for the sequential extrusion of multiple plastic materials, will achieve technological breakthroughs in the next few years and be recognized by related blow-molded product manufacturers.

4. Electric hollow plate forming unit

In recent years, the electric hollow plate forming unit has great advantages in the clean production and energy saving of blow molded products, and its research and development progress has been rapid. For some blow molding production workshops that require a high degree of cleanliness, the electric hollow plate forming unit will be one of the preferred choices. At present, large and medium-sized electric hollow plate forming units are relatively rare. With the increasing requirements for clean production of some large and medium-sized plastic barrels, the development of large and medium-sized electric hollow plate forming machines will likely be accelerated. At present, the general electric hollow plate molding machine is mainly used in some high-end blow molding product industries and industries that require highly clean production. With the further reduction of equipment manufacturing costs, it may be promoted to other blow molding product industries.
