Wuhan Handern Seiko wish you a happy New Year
The spring of the year of the ox is so beautiful, the lights are full of peace, the fireworks are all over the night sky, the auspicious firecrackers are resounding through the sky, the laughter is filled with happiness, the new year is coming, all members of Wuhan modern Seiko Machinery Co., Ltd wish you a happy New Year!The company is the enterprise technology center of Wuhan City, and also a national high-tech enterprise in the field of plastic engineering machinery technology and equipment. It has dozens of advanced manufacturing supporting precision processing equipment and industry-leading testing equipment. It is a technology driven enterprise integrating production, learning and research. Especially in plastic extrusion equipment. PP hollow board production line www.handern.com
The plastic extruder is usually called the main machine, and its supporting follow-up equipment plastic extruder is called the auxiliary machine. After more than 100 years of development, plastic extruder has been derived from the original single screw twin-screw, multi screw, even no screw and other models. The plastic extruder (host) can be matched with various plastic forming auxiliary machines, such as pipe, film, holding material, monofilament, flat filament, packing belt, extrusion net, plate (sheet) material, profile, granulation, cable coating, etc., to form various plastic extrusion production lines and produce various plastic products. Therefore, plastic extrusion molding machine is one of the widely used machines in plastic processing industry no matter now or in the future.
The main machine of plastic extruder is extruder, which is composed of extrusion system, transmission system and heating and cooling system. PP hollow board production line www.handern.com
The extrusion system consists of screw, barrel, hopper, head and die. The plastic is plasticized into a uniform melt through the extrusion system, and under the pressure established in this process, it is continuously extruded by the screw.
Screw: is the most important part of the extruder, which is directly related to the application scope and productivity of the extruder. It is made of high-strength and corrosion-resistant alloy steel.
(2) barrel: it is a metal cylinder, which is generally made of alloy steel or composite steel pipe lined with alloy steel with high heat resistance, high compressive strength, strong wear resistance and corrosion resistance. The barrel and screw cooperate to crush, soften, melt, plasticize, exhaust and compact the plastics, and continuously and evenly transport the rubber to the molding system. Generally, the length of the barrel is 15 ~ 30 times of its diameter, so that the plastic can be fully heated and plasticized.
(3) hopper: a cut-off device is installed at the bottom of the hopper to adjust and cut off the material flow, and a sight hole and calibration metering device are installed at the side of the hopper.
(4) head and die: the head is composed of alloy steel inner sleeve and carbon steel outer sleeve. The head is equipped with a forming die. The function of the head is to transform the plastic melt in rotary motion into parallel linear motion, evenly and smoothly lead it into the die sleeve, and give the plastic with the necessary forming pressure. The plastic is plasticized and compacted in the barrel, and flows into the forming die of the head through the neck of the head along a certain flow channel through the porous filter plate. The core and sleeve of the die are properly matched to form an annular gap with decreasing cross section, so that the plastic melt forms a continuous and dense tubular coating around the core. In order to ensure that the plastic flow channel in the die is reasonable and eliminate the dead angle of accumulated plastic, a shunt sleeve is often installed. In order to eliminate the pressure fluctuation during plastic extrusion, a pressure equalizing ring is also set. PP hollow board production line www.handern.com
In the end, he is brave, high spirited, short-time and long-lasting. Yesterday is gone, and the new year is coming. It's a happy beginning and a brand new hope! New year, a happy smile, a good mood. Happy New Year!
