How to prevent the alloy screw from slipping? Let's take a look

When the alloy screw is difficult to press the material at the feed port, or cannot form sufficient adhesion along the length of the barrel to convey the material, the screw slips. In the screw preforming stage, when the screw rotates in the barrel to convey the material in the direction of the screw and retreat for the next injection to accumulate the material, the screw will also slip. If the screw starts to slide during the preforming stage, the axial movement of the screw will stop as the screw continues to rotate. Usually, screw slippage will lead to material degradation before injection molding, and some product quality problems such as short injection and prolonged processing cycle will occur.

Analysis of Partial Causes of Breaking of Barrel Screw

Part of the cause analysis of the breakage of the barrel screw: the fracture temperature of the barrel screw is also related, but it is very rare. Almost all the barrel screw itself has poor material toughness, and it is still a used or refurbished screw! The raw materials are rough, such as the raw materials added with GF [glass fiber] that kind of raw materials cost screws and machines!

The benefits of properly adjusting the back pressure of the barrel screw

The benefits of properly adjusting the back pressure of the barrel screw The barrel screw can compress the molten material in the barrel, increase the density, and improve the stability of the product injection volume, weight and size. The gas in the barrel screw melt can be "squeezed", reducing the air flowers and internal bubbles on the surface of the product, and improving the uniformity of gloss.

What are the structural characteristics of 110 cone

110 cone double is a 110 cone double that can concentrate on a series of basic chemical unit processes such as solid conveying, pressurization, melting, exhaust, dehumidification, melting conveying, pumping, etc. It is a machine running on a rod. Compared with single screw extruder, 110 cone double can melt and mix more fully, so it is more widely used. So, let's learn what structural characteristics the next 110 cone double has!
