Get a Grip on Screw Slippage : Plastics Technology
Dec 01, 2008 · Get a Grip on Screw Slippage Screw slippage occurs when the screw in the barrel of the injection machine has difficulty picking up material from the feed throat or is unable to develop enough tack to convey the material down the length of the barrel.
Injection Molding Screw Design The observed differences between plastics processing in Extrusion and Injection Molding Quality Control Plastics processing requirements in injection molding are similar to the requirements in the extrusion industry. Many of the terms are different for example, rate in extrusion is defined as pph/rpm, and in injection oz/sec.
How to Design Efficient and Reliable Feeders for Bulk Solids
The key to proper screw feeder design is to provide an increase in capacity in the feed direction . This is particularly important when the screw is used under a hopper with an elongated outlet. One common way to accomplish this is by using a design as shown in Fig. 1.
Nordson has been around since the beginning of plasticizing screw technology, with several of our early extruder screw models earning patents. Since then we''ve been continually innovating to create the highestquality bimetallic screws for use in extrusion and injection molding.

The screw tip valve is one of the key components in the molding process. The everwidening range of both materials and processes faced by injection molders, along with the need for increased quality and productivity, makes screw tip valve function even more of a critical concern. The feed screw rotation moves and melts material
Barrier Screws. Unlike the injection molding industry, the extrusion industry does not use GP screws, or even refer to them as general purpose. Instead, they are commonly referred to as "square pitch" screws, as the pitch of the single flight is equal to the diameter.
