WebFlow Length The flow ratio is the flow length in the mould divided by the wall thickness of the moulding. A number of factors can affect the flow ratio such as melt flow rate, the processing conditions and the features of the mould. Thick sections enable higher flow ratios to be achieved while very thin sections have the opposite effect. gardiner mt hotels near yellowstoneWebSep 18, 2024 · Aspect Ratio: Aspect ratio is a numeric value for the ratio of flow length to wall thickness. The aspect ratio is directly proportional to the clamping force. Low aspect ratio means low packing pressure, eventually, it means low clamp tonnage.
