Hose production line in the mold role

Zhangjiagang Sansu Machine Co.,Ltd | Updated: Jan 25, 2018

Compression ratio in the mold PVC hose is the material in the mold flow convergence after seam strength of the key, is also an important factor affecting the impact strength of the PVC hose. 

The flow state of the material in the mold has a great influence on the performance of the products. Good mold, the material flow in it should be smooth laminar flow, no eddy current phenomenon. The internal stress of the PVC macromolecule chain in the flow is small, and the strength of the product is great. Poor mold production is not only unstable, but also the mechanical properties of products are also poor, often used to adjust the formula, resulting in higher costs.
