How to Choose an Injection Screw Barrel for Your Machine
2022.10.08
When choosing an injection screw barrel for injection machine, there are a few important things to keep in mind. First, you should know how much work each screw can do. This is measured by the compression ratio between the flight depth of the feed section and the metering section. It also describes how much material can be moved by a single turn. Most engineers use a linear ratio for compression. A typical compression ratio for an extrusion machine is four to one. However, you should keep in mind that this compression ratio is different than that for an injection molding machine.The screw and barrel selection process is critical to the success of your machine cell and the application of plastics.

Although it may seem like a simple process, choosing the right screw and barrel combination can make a difference in how well your components come out of the injection machine. Many people do not realize just how often they choose the wrong screw and barrel combination for their application.The plastic material used in injection molding machines has many properties that affect the performance of an injection screw barrel. It must be kept at a lower temperature to avoid degradation and is designed to be injected at higher pressures for longer cycles. Initially, plastic barrels were cooled before being used in injection machines. This forced the manufacturers to increase their pressures and extend the cycle for injection.Concor Tool and Machine offers a variety of replacement screws for injection molding machines, extrusion machines, and other equipment.
Its extensive line of products includes a wide variety of premium designs and materials. These products are designed to give your machine a competitive edge and boost processing speeds.With the increased use of injection molding and extrusion, the demand for feed screw barrels is increasing. This tool is a critical part of the plastic processing machinery, and without it, the process would not be complete. To meet the growing demand, leading manufacturers of feed screw barrels are increasing R&D investment in computerized drawings and designs. This innovation helps them increase customer satisfaction and ensure high-quality products during the various molding processes.The screw barrel of an injection machine is an important component that needs to be durable, dependable, and of high quality. There are many options when it comes to choosing the right screw barrel. The choice should be made after considering the materials that will be processed. The screw diameter will determine the material that can be processed and the screw volume is important for optimum performance. Low inj volume can lead to premature wear and tear of the screw flights.One option is a bimetallic screw barrel.
This type of screw is made from a screw base and a second metal, which is a hard and durable metal. Both metals can be case-hardened or through-hardened. These types of screw barrels can also include a tungsten-carbide or nickel coating.If you are considering purchasing a new injection screw barrel for your plastic machine, you should consider the CPM 10V. This alloy has been making significant headway in the industry, thanks to its use in IMM Barrels. The screw and barrel work together to melt, convey, and generate pressure in the extruder. Both components need to be carefully monitored and controlled to ensure a consistent plasticized result.After selecting the CPM 10V injection screw barrel, you should take several steps to prepare it for injection. First, the barrel must undergo a channeling process. To do this, the outer diameter is first laid in a spiraling manner. After that, hard-facing alloys are applied to the channels. Then, a welder is used to weld it together. Once the barrel is finished, it is inserted into a tank filled with vermiculite and left there for two or three days.
