Thin wall injection pressure

WebJun 1, 2024 · It also influences the ability to pack out the part. If the gates are too small, the injection pressure during fill will be very high, and the ability to pack out the part will be negatively impacted. In our example of the automotive A-pillar, the material must flow 55 in. through a 0.080-in.-thick wall, which yields an aspect ratio of 688:1. WebAug 1, 2024 · Since thin wall injection molding involves higher injection speeds and pressures, gates should be larger than the part’s walls to help minimize gate wear and material shear. This will also help prevent or eliminate freeze-off from occurring before packing is achieved.

WebOct 10, 2024 · Because pressure is required for the injection molding process, thin wall areas in a mold can cause material flow rate issues no matter what material is chosen. ... If you need more than 200 tons of pressure for a machine with a range of 100–200 tons, then you’ll need to use a bigger machine, and bigger machines have higher operating costs. ... Thin wall injection molding is a specialized form of conventional injection molding that focuses on mass-producing plastic parts that are thin and light so that material cost savings can be made and cycle times can be as short as possible. Shorter cycle times means higher productivity and lower costs per part. The definition of thin wall is really about the size of the part compared to its wall thickness.
