The relationship between the thickness of the plastic barrel wall and its deformation

- Nov 25, 2019-

The deformation problem of the plastic barrel is a place that attracts many users, and there is a certain relationship between the deformation of the plastic barrel and the thickness of the barrel wall; in the actual use of the plastic barrel, the thickness of the barrel wall varies greatly. As a result, the deformation of the plastic barrel has caused the plastic machinery manufacturing enterprises to attach great importance to it. The improvement work in this area has been started, and most of the plastic barrel manufacturers have also actively improved the mold equipment.

Plastic barrels produced by manual equipment, no wall thickness control points or less, can easily cause unevenness of the plastic barrel as a whole, so it is relatively loose when formulating the standard of plastic barrels. The two points of the plastic barrel are thick. Should be controlled within the 2:1 range. In this case, the plastic bucket with uneven wall thickness of the bucket is often qualified when it is subjected to anatomical analysis.

The current automatic blow molding machine blank thickness control device controls the wall thickness of the parison, and the control point is up to 128 points, generally 20 to 30 points. The effective wall thickness control makes the thickness of the barrel wall uniform as required, and the anti-fall is greatly enhanced.
