CHEMECHINA EXTRUSION TOOLING
Host is extruded plastic extruder machine, which consists of extrusion system, transmission, and heating and cooling system.
Twin-screw extruder
Twin-screw extruder
1 extrusion system extrusion system includes screw, barrel, hopper, nose, and mold, plastic extrusion system and plasticized by a homogeneous melt, and in the process established under the pressure of being a continuous screw extrusion head.
(1) Screw: Is the most important part of the extruder, it is directly related to the scope and productivity of the extruder, from high-strength corrosion-resistant alloy steel.
(2) Barrel: Is a metal cylinder, usually with heat-resistant, high compressive strength, extremely resistant, corrosion-resistant alloy steel or alloy steel lined composite steel pipe. Barrel and screw together to achieve plastic crushing, softening, melting, plasticizing, exhaust and compaction, continuous and uniform delivery system to the molding compound. Its barrel length is generally 15 to 30 times the diameter, to obtain sufficient heat so that the plastic and sufficient plasticizing principle.
(1) head and die: Die from alloy steel and carbon steel inner sleeve jacket structure, built with the head mold. The role of head of the plastic melt rotary motion into linear motion parallel and evenly smooth import mold sets in, and give the necessary plastic molding pressure. Plastic barrel plasticizing compaction, neck and head through the porous filter plate mold flow into the nose along a certain runner through the core die sets proper fit, forming an annular gap decreasing cross-section, so that the plastic melt forming a continuous coating layer around the tubular dense core wire. To ensure the plastic flow path within a reasonable head, eliminating the accumulation of plastic corners, often placed there shunt sleeve, pressure fluctuations for the elimination of plastic extrusion, also set equalizing ring. Machine head is also equipped with mold correction and adjustment device, easy to adjust and correct the mold core and concentricity die sets.
Extruder in accordance with the direction and angle of the screw head stream centerline, will head into the head angle (the angle 120o) and right-angle handpiece. Head shell is bolted to the body, head mold inside the cores sit in front of the nose and fixed line ports, core seat is equipped with a nut core, core and core seat with a central opening for passing the core wire; Fitted in front of the nose portion of the strap rings for pressure equalization; Molding part extruded from the die and die sets composed of the socket, the position of the die case can be adjusted via a support bolt to adjust the relative position of the die core sleeve, and easy to adjust uniformity of the extruded cladding thickness. Head outside and the temperature measuring device is equipped with a heating device.
Transmission drive system 2 is the role of the drive screw, feed screws in the extrusion process and the speed of the torque needed, usually by the electric motor, gear and bearing components.
2 heating and cooling apparatus for heating and cooling is a necessary condition for plastic extrusion process can be carried out.
Cooling means in order to ensure that the plastic temperature range required for the process settings. Specifically, in order to eliminate excess heat generated by the friction of the screw rotating shear, in order to avoid overheating the plastic decomposition, scorch or stereotypes difficulties. Cylinder water-cooled and air-cooled cooling is divided into two kinds, most small and medium extruder using air more appropriate large is to use more cooling water or in combination of two forms; Screw water-cooled cooling centers mainly aim is to increase the delivery rate of the solid material stable volume of the plastic,
CHEMECHINA China CHEMICAL MACHINERY INTERNATIONAL Co., Ltd. is an exclusively foreign-owned enterprise founded at Bonded Area of Dalian China in 2001, in which was joint invested by one American and three Austrians.
Since then by the consistent efforts of our elite leading team that comes from America, Austria and Germany, 100% of our wide variety rubber & plastic processing production lines and tooling have been exported to some European counties such as Germany, Austria, Russia, Danmark and Poland...., and obtained great compliments. Therefore, it substantially implements our mission: Assure the European top quality and keep the Chinese cheap price.
Now CHEMECHINA has become a strong international group company with three factories and three companies. Here is brief introduction of them as follows:
The president of Shanghai KANG LEE MACHINERY FACTORY, Mr. Lee Kang has 29 years feeding, weighting, mixing and pneumatic conveying equipments manufacturing experience. The main products are rubber and plastic auto feed production line, dry mortar production line, foamed cement production line and ceramic plate pneumatic feeding system. The considerable market share has gained both at home and abroad.
The president of Shanghai XIECHENG RUBBER & PLASTIC MACHINERY FACTORY Mr. Zhang Jicheng has 20 years sales and after-sale-service agent experience for the Krauss-Maffei Group Germany. Since the year 2002 the factory has rapidly grown up as a top manufacturer of high-end extrusion machine in China. The exporting value has reached 6 million U. S. Dollar per year.
The DALIAN EXTRUSION Technology Co., Ltd. Was founded in 2001 in Dalian China. It is owned and managed by the three leadership members who are from Austria Greiner GmbH.
All of our products, about 300 sets extrusion tooling per year, have wholly exported to the Europe countries such as Germany, Austria, Russia and Poland...., annually exported value are reached to 4 million U. S. Dollar. The ETDbrand, especially the patent of 6 m/min. High speed PVC extrusion tooling for window and doors are most prestigious in Europe.
The durable standards of tooling we made are as same as European Norm that should be used to produce one million meters profiles. Actually at some PVC profile manufacturing plants in Germany and Russia our tooling have magically produced 3 million, even 5 million meters PVC profile, but it is still using now. This is the fact of our reliable quality!
The branch company CHEMECHINA TRADING GmbH in Austria is in charge of European marketing development. Mr. Lothsa Hans and his elite sales team have wide sales nets in Europe. They made very great contribution every year more then a decade.
The branch company CHEMECHINA ENGINEERING GmbH in Germany is in charge of field installation and tuning works as well as after-sales-service. The engineer Mr. Luca Finn and his team have exquisite skill, rigorous and precise working attitude. More then a decade they ensure all of production lines and tooling we exported to the Europe in a normal operating condition and gained consistent high praise from our clients of the Europe countries.
With the equipments, staff and capacity growing up, not only the European market but also the Global Marketing strategy has put into the top agenda. We organized a fine marketing team to expand towards North & South American, Asia, Africa and Australia markets. We warmly invite worldwide companies or individual to join us as a salse and after-sales-service agent in your country. Let the world understand CHEMECHINA and share our top quality but cheap price products, meanwhile, we firmly believe the CHEMECHINA will gain a global reputation in the near future.
