How to correctly operate the three layer coextrusion film blowing machine?

  Preparation before the operation of the three layer coextrusion film blowing machine, check the water, gas and heater is damaged or complete, confirming all die and extrusion machine power supply is connected properly. First in accordance with the specifications of the products the roll core on the roll bar on, cut knife position adjustment to the required size and position, die, herringbone frame, the first traction, rectifying system, electric spark, the second traction, coiling. When the membrane and correction machine swing reduction, and timely closure of top clamp roller speed, timely closure coiling machine operator according to the actual situation make adjustments in a timely manner. All the polymer materials exposure under UV irradiation will degenerate, gains the membrane surface added UV inhibitors and absorbent, form the membrane stability and to prolong the service life of plastic sheeting, and their life depends on the thickness of plastic sheeting and anti UV additive proportion, up to a maximum of five years.

  Film blowing machine manufacturers new film blowing machine, sheet film blowing machine, PE film blowing machine, three layer coextrusion film blowing machine, and so meet the packaging of various products on the market, high-end film quality won the favor of the luxury goods packaging. Today, film blowing machine development of high-end technology, blown film also can be used as pharmaceutical, food preservation and application of a number of technology, go of new blown film machine manufacturing.

  At present, people have developed a variety of methods for multicomponent sheet products, by CO extrusion process is a method which is simple, the method has become one of the most advanced plastic forming method. Production of environmentally friendly film blowing machine (such as water soluble film, starch film, light degradable film, biodegradable film, etc.). Dalian three layer coextrusion film blowing machine manufacturers to follow up on the market, increase profits, often in the hope that can produce some high value-added, have special use film, which the domestic existing film blowing unit proposed a major requirements: can adapt to the current domestic market performance of the proposed film product requirements.

  Some domestic companies have launched a plastic heavy packaging film equipment, mainly including three layer coextrusion blow molding packing film unit and five layer co extrusion heavy packaging film unit. Polymer sheet extrusion is a multiple extruder respectively supply different melt flow, in a complex head exchange aggregate extruder process of multi-layer composite sheets.

  The Middle East, South America, the CIS and countries in Southeast Asia plastic machinery market, in recent years also gradually open, due to institutional reasons, situation of each country's economic development is different, need plastic machinery are not the same, on the top of the high-grade plastic can say is a piece of virgin land has yet to be people to develop, want domestic plastic machinery manufacturing enterprises, seize the opportunity, enterprising, to develop the enormous potential of the domestic and foreign plastic machinery market, make their own businesses have greater development. Three layers of thin film production technology has been mature, are used in the cone and flat stacking machine head, the level of the tractor, automatic coiling machine, corona processor, internal cooling system and rectifying device, etc..
