The development trend of blow moulding
Dalian hollow moldingManufacturer for everybody introduction to the development trend of blow moulding.Seen from the trend of the development of the market both at home and abroad, as a result of plastic bottles, plastic buckets, auto parts and industrial blowing a lot of blow molding products such as large-scale production needs, all kinds of big small and medium sized high speed, stable, energy saving, perfect supporting auxiliary machinery of professional, fully automatic production line will be in the next few years the development of the mainstream.
1. The multilayer hollow molding unit, the production line
(1) multilayer three-dimensional hollow molding machine.The current domestic hollow molding machine manufacturers have multilayer three-dimensional hollow molding design and manufacturing capacity of the unit, but because of the current domestic haven't have a huge market demand, so the technology research and development is relatively slow.The development of domestic sedan industry and upgrade will boost the research and development of the unit.
北京赛车(2) multilayer chemical plastic hollow molding machine.Qinchuan development design and manufacture of SCJ - 230 x 2 double large blow molding unit is mainly used for production of 200 l series double plastic, have a larger share in the domestic.In order to meet the requirement of large blow molding products manufacturers at home and abroad, the domestic hollow molding machine production enterprises to strengthen the double, three layers and layers of large hollow molding unit research and development work, high production and high energy saving, save uniform wall thickness, plastic raw materials, long-term stable operation will be one of the main research focus of such equipment.
(3) the car multilayer plastic fuel tank production equipment.Qinchuan development research and development of SCJ - 500 * 6 layers of plastic fuel tank large blow molding unit, in alternative has made larger into related imported equipment products.If the unit adopts the domestic flexible QuHuan radial control system to control the radial plastic parison wall thickness, will make the equipment technical level has reached a higher level.
(4) multilayer daily chemical product packaging plastic bucket, plastic hollow molding machine production line design and manufacturing technology for many companies, such as Hong Kong qi group, guangdong kaiping with large plastic machinery factory, suzhou.Is expected in the next few years, the plastic bucket, plastic multi-layer hollow molding machine production line will speed up the pace of development, will pay special attention to form a complete set of mould, automatic to flash, automatic labeling, automatic detection and automatic packaging research, for blow molding products manufacturer to further reduce production line operators to provide equipment and technical support.
北京赛车2. The large and super large hollow molding unit, the production line
(1) other large blow molding machines.China is a country with a variety of climate conditions, the requirements of the use of a variety of different water storage tank, storage tank are larger market demand, therefore more adapt to research and development products market demand large blow molding machines is one of development direction.In recent years, some large blow molding products research and development of the joint equipment manufacturer, manufacturer of storage tank, water storage tank production equipment, its products volume has reached 2000 l.Such as weifang huayu plastic machinery co., LTD. Design and manufacture of large water storage tank is comparatively mature production equipment.
北京赛车(2) hollow blow molding tray with large units, production lines.Logistics, food, chemical fertilizer, petrochemical industry, daily chemical industry, railway transportation and storage, pharmaceutical and feed, beer, beverage and other industries, the rapid development of stemming tray manufacturing especially blow molding tray with the rapid development of manufacturing industry.
Although the industry in recent years, plastic tray obtained great development, but as a result of injection molding tray plastic raw materials and the forming mechanism of the inherent limitations, in the use of environmental temperature difference is bigger, and high strength under the condition of frequent use, short service life, easy damaged impellers.And high strength blow molding tray has the advantages such as high impact strength, durable, is listed as the first choice for plastic tray, its market demand growth at about 20%, and the intensity of the domestic high blow molding tray basic within 1 million yuan, the annual production capacity of far cannot satisfy the demand of the market.
(3) the IBC plastic packaging barrels of large-scale hollow molding machine.Domestic production enterprises have many empty machine can manufacture 1000 libc plastic production equipment, but more is given priority to with universal equipment.Current domestic plastic parison wall thickness 1000 l blow molding machines less radial control device, the product at the four corners of uneven wall thickness control, raw material consumption, influencing the full play of the molding equipment performance, worth has drawn great attention of domestic large-scale hollow molding machine manufacturing enterprises.
Most of the current domestic large hollow machine is given priority to with gm model, is used in the production of the 1000 libc plastic buckets and used for blow molding tray production, equipment capacity cannot give full play to.Therefore, stepping up efforts to develop the professional production of large and super large hollow blow molding tray forming unit, high speed production line is one of the main direction of some industry enterprises.
3. The electric type hollow molding machine
In recent years, the electric type hollow molding unit in blow molding products of clean production, energy conservation and has great advantage, its research and development progress quickly.For some need highly clean production workshop, blow molding products electric type hollow molding is one of the unit.The current large and medium-sized electric type hollow molding unit is relatively rare.As for some large and medium-sized plastic improvement of clean production, the development of large and medium-sized electric type hollow molding machine could speed up.The current general electric type hollow molding machine is mainly used in some high-end blow molding products industry and need a highly clean production industry, as equipment manufacture cost further reduce will may be popularized to other blow molding products industry.
4. Other special hollow blow molding machine
Special function of blow molding hollow molding unit development require blow molding products manufacturers work closely with equipment manufacturer.Some of the special automobile, motorcycle industry is expected to blow molding products, such as a variety of plastic materials in the order of extrusion blow molding pipe) hollow molding unit will gain breakthrough in the coming years, and get the blow molding products manufacturer approval.
