Spinneret is an indispensable precision part in the spinning machine of chemical fiber industry. Its function is to extrude fiber bundles with certain thickness and fine texture through micro holes on spinneret. The quality of micro holes on spinneret is the essential condition for the design principle of heavy spinneret to ensure the quality of fiber products and good spinning process. Generally, the number of micropores on a spinneret is about 64, the diameter of micropores is about 0.2-0.5mm, and the shape of spinneret is mostly circular.

At present, The quality of spinneret holes in new spinnerets is checked by manual microscope projection method, which is applicable to spinnerets with few holes in the spinneret plate of chemical fiber. For enterprises with many spinneret holes or large spinning output every day, the design principle of spinneret plate can be checked by dynamic spinneret plate Measurement system, this equipment has high mechanization, labor saving, high detection efficiency and detection speed block.

For conventional circular spinneret with diameter of 130mm, The circular spinneret with the number of holes less than 200 can be used to test the spinneret by the method of microscope projection. The spinneret tester can recommend the glass table of Changzhou Jiehua Precision Machinery Co., Ltd. manual spinneret mirror tester (conventional type). The spinneret is placed on the glass platform, and the design principle of the spinneret is shown on the 17 inch Dell display through the design principle of the spinneret Observe on.
