Injection molding method uses solid materials and aluminum alloy, while direct injection method uses plastic or polystyrene materials. These two types of process produces barrels and screws that will be used in industries that are concerned with material and product durability, but also want a fast production process. Direct injection molding is ideal for assembly of metal shafts, components and other assemblies, where fast results are of utmost importance.
The barrel or threads of a plastic extrusion tool can wear over time, causing the head of the screw to loosen and become damaged. The threads of a screw can also become stripped, making it difficult to use the tool. This can happen when the screws are overused or improperly tightened. As you use your plastic extrusion tools, this can eventually occur. If this happens to your equipment, you must replace the barrels with a different size or face.
We have a number of solutions for this situation. You can either change or replace the barrels before they become too worn, or you can prepare the base material and the barrels before starting your work. By preparing the base material and the barrels before starting, you avoid any possibility of stripping, or changing the screws too early. In addition, preparing the base material and the barrels before starting will ensure that the screws do not strip as they are used. The two options allow you to maintain your equipment while making small modifications to it to improve its performance.
When purchasing plastic parts for your tools, we recommend that you purchase from a manufacturer that specializes in injection molding.
