Repair principle of barrel screw

The two important parts of the screw and the barrel, one is a slender threaded rod, and the other is a relatively small and long hole in diameter. Their machining and heat treatment processes are more complicated, and the accuracy is more difficult to ensure.

Wear Repair Technology of Barrel Screw

The wear of the barrel screw is mainly manifested in the wear during use, especially when the use of long-term or long-term production of high-filled or glass fiber reinforced materials, resulting in an increase in the inner diameter of the barrel. Because the inner surface hardness of the barrel is higher than the screw, the damage of the barrel is slower than the screw.

Which kind of screw is better for film blowing machine

Screw? 1. Different raw materials need to choose different structure of the barrel screw. 2. The production of different products need to choose different barrel screw. The same raw materials, but the quality of the raw materials has changed, and the requirements for the barrel screw will also be different. Here are the references: (I) yield The so-called yield refers to the yield or extrusion of a given head under the premise of ensuring the quality of plasticization. As mentioned earlier, production is generally expressed in kg/hour or kg/turn. A good screw should have a high plasticizing capacity. (production capacity) It should be noted that low-temperature extrusion is the objective.

Use conditions and methods of barrel screw

The method of resistance heating is widely used for simple heating, and thermocouple is used to realize segmented temperature control and side inspection. Resistance heating is to use resistance to generate heat to heat the barrel, and then transfer the heat to the plastic in the barrel. Resistance heating mainly strip heater, cast aluminum heater, ceramic heater and so on. These heaters have the advantages of small size, convenient manufacture and maintenance.
