High And Low Pressure Die Head

Blown film machine die head consists of two inseparable parts: die body (die core, die cylinder, die ring) and heater (heating ring). The first step is to select the material, that is to choose the corresponding material.
 
The second step is forging, forging the material into the rough embryo of each part of the mould, the molecular structure of the forged embryo is more dense.
 
The third step is to carry out lathe processing, according to the design drawings of the mould head to turn out the mould head, in the lathe processing, as far as possible, with high precision lathe, and the technology of the old
In the lathe processing, we should use the high precision lathe as much as possible, and the skilled lathe master.
 
The fourth is polishing, put the car good mould of the runner part of the polishing, the better the finish, blowing out of the film is also the better, the more there is no silk road.
 
The fifth is chrome plating, the polished mould runner part plated with chrome, so that the runner part has a layer of very hard chrome, increasing the wear resistance and corrosion resistance of the die head and then polished, can make the die head more durable.
 
Corrosion and then polish, can make the mould is not easy to damage and not easy to produce stagnant charcoal. Finally, install the mould parts and put on the heating ring.
 
Then the mould is finished. The structure of the die head is based on the characteristics of LDPE, HDPE and LLDPE polyethylene, and has been selected after many comparative tests.
 
It has the advantages of large internal pressure, stable and uniform extrusion, good film strength performance, no seam and good matching with the extruder of this unit. Simultaneously change three kinds of polyethylene
 
At the same time change three kinds of polyethylene and the proportion of mixture, recycled material for blown film production can not change the die head.
