Xin Huaxu how to exclude bad seal abnormal

Xin Huaxu seals in the open mold design and manufacturing precision error is small, the weight of the compound to calculate accurate, so that can effectively reduce the amount of effective products flash, and lack of material phenomenon.

In the molding process Xin Huaxu seal forming temperature is too high or up and down the template temperature is inconsistent, exhaust row is too open or exhaust time too late. Rapidly cooked material, mold structure is irrational, there is no run trough, the weight of heavy materials. All will lead to Xin Huaxu seals flash serious.

Poor mold exhaust conditions can cause air bubbles

In Xin Huaxu seal forming process, the curing process is the last one. In this process, the rubber through a series of complex chemical reactions from the linear structure into a body structure, the loss of the plasticity of the rubber with a cross-linked rubber high elasticity, and then get good physical and mechanical properties, heat Resistance, solvent resistance and corrosion resistance of rubber products to improve the use value and scope of application.

Before vulcanization: linear structure, intermolecular van der Waals interaction; performance: plasticity, high elongation, soluble; vulcanization: molecules are triggered, the occurrence of chemical cross-linking reaction; vulcanization: network structure, intermolecular Has been chemically bonded. Xin Huaxu seals to meet the requirements of the performance of this process will be strict requirements.
