Plastic extrusion process is the most common product deformation, caused by what factors? What measures should be taken?
1. The sizing sleeve itself is deformed, and the sizing sleeve needs to be replaced or corrected;
2. The product falls out of roundness when it is not finalized, and the finalize water or vacuum degree needs to be increased;
3. If the traction pressure is too tight and compressed, the clearance of the traction belt should be adjusted appropriately;
4. The position of the supporting wheel in the styling box is too high, causing the lower end of the product to be flat. The tug wheel should be adjusted to make it concentric;
5. If the impact of cooling water is too great, it will be cooled without being well shaped by vacuum. The water flow should be appropriately reduced.
