The development of three-dimensional (3D) in extrusion blow molding machine points: understand for 3D catheter of the new resin and its development trend, the extension of application fields; development 3D running mechanism and its control system; adapt to the development of new resin plasticizing mechanism and machine head; active digestion and absorption of advanced foreign technology, standing on the high starting point of development three-dimensional (3D) extrusion blow molding machine.
7 injection molding equipment for hollow plastic
Injection of hollow plastic molding is no blow molding hollow molding, in mold, control system, forming process, after treatment, different from ordinary injection molding and extrusion blow molding, molding products, the main advantage of: high degree of products, shape and surface quality is high, and is especially suitable for some complicated industrial hollow products. Hollow plastic injection molding equipment, in the following aspects of development:
Die slide injection hollow plastic molding, the principle is: first hollow products is divided into two parts, the two parts were injected into the formation of semi-finished products, and then the two part semi-finished products and mold sliding to the position, second clamping, two parts of work in process (WIP) combined with joint injection of plastics melt (second injection). Finally, we get complete hollow products. Compared with blow molding hollow products, this method has high surface precision, high dimension precision, uniform wall thickness and high degree of freedom of design. In producing a complex shaped hollow products, die slide injection hollow plastic molding method and ultrasonic welding advantages compared to is: without semi-finished products are removed from the mold, and can avoid the semi-finished products in the mold cooling caused by decreased accuracy of product shape, avoid welding method to produce local stress problem of weldline strength decreased by.
The principle is: first, the 2.5 shell is produced by the method of injection, and the 2.5 shell is welded together to form a hollow product. Half shell injection molding of hollow plastic is the key to the design of the products, to make half shell products were taken out of the mold cooling and welding, the accuracy of products to meet the requirements. Automobile engine intake pipe, automobile fuel tank, half shell hollow plastic injection molding is available.
Fusible core injection molding hollow plastic molding, the principle is: use of low melting point metal as injection mould core to produce the internal and external surface shape complex and require smoothness and size of the internal requirements of precision hollow plastic products. The key to this technique is: plastic injection, the core may melt down. As the core of the metal melt and used to core melting medium can't be corrosion on plastic; in the temperature of the molten core parts can not be deformed. Can be fusible core injection molding hollow plastic molding in automobile engine full plastic long integrated air inlet pipe in the field has been widely used, new uses are: auto water pump, centrifugal water pump, spacecraft pump pump driving gears.
8 electric bottle blowing machine
Electric bottle blowing machine is a product that needs to be actively developed. There are two kinds of electric bottle blowing machines: the driving mechanism is mainly driven by electric, hydraulic or pneumatic drive, all electric drive (including servo motor drive, frequency conversion motor drive). Energy saving is one of the main topics in the development of the bottle blowing machine.
All electric in extrusion blow molding machine, key is with high efficiency electric drive to replace hydraulic drive, with energy-saving electric drive to replace the traditional electric drive. It is not only energy-saving, but also can reduce the environmental pollution caused by noise and improve the overall performance.
One-step injection stretch blow molding blow molding machine is mainly molding beverage bottles, fruit pulp bottle, transfusion bottles, etc. to improve the products of the self-cleaning developed the electric driving device is very necessary. It is the key to the implementation of turntable mechanism, preform molding clamping mechanism, blowing synchronous clamping mechanism, injection plastifying mechanism etc. achieve full electric drive.
The main advantages of all electric pull blow bottle machine is: accurate positioning, fast speed, no vibration, self-cleaning, high efficiency. To achieve full electric "one-step" stretch blow bottle blowing machine, mainly close mould mechanism of the drive for the electric drive, such as servo motor drive the ball screw driving toggle clamping mechanism. 9 plastic bottle blowing machine
The other forming methods difficult to molding hollow profiled complex products with rotational molding hollow molding has obvious advantages, especially in the chemical industry with great development prospect. All thermoplastic plastic powder can be rotational molding, and extended to the field of thermosetting plastics and crosslinking.
Plastic bottle blowing machine overall technology to the development of automation. In the heating method, the heating system is heated by the hot air circulation method and the open flame heating method, the heating method, the molten salt heating and the infrared heating method and so on.
The development of multilayer hollow molding rotational molding. Multi fuel tank and rotational co extrusion fuel tank to be competitive in terms of cost and performance.
Plastic bottles and products can be successfully transported from one machine to another machine is the main factor of the whole line running speed. The delivery process must be smooth and continuous, and the maximum flexibility is needed to cope with sudden changes in production. Need an automatic blow molding machine model of the automatic control system and the advanced technology of the eye, to ensure that in each production link transmission line has the best performance. The conveyor line system of the automatic bottle blowing machine adopts the most advanced technology and the highest quality material.
