1) Shorten the molding cycle Because there is no limit to the cooling time of the sprue system, the parts can be ejected in time after being formed and solidified. Many thin-walled small parts produce

The injection molded part breaks when it is ejected, or is easy to break or crack during handling, how to solve it? The following gives the cause analysis and suggested remedies from several aspects 1

The various tools used in our daily production and life, ranging from fuselage shells, as small as embryo head screws, buttons and the shells of various household appliances, are inseparable from the

Why do some polymer materials need to be dried before injection molding? The chemical structure of a particular polymer determines whether it will absorb moisture due to their polar chemical structure

The general properties of crystalline polymers are: distinct and sharp melting point, higher specific gravity, higher tensile strength and tensile modulus, lower ductility and impact strength, creep r

The rate of crystallization is dependent on temperature, of which there are two significant points: ( The glass transition temperature. Below Tg, there is virtually no molecular motion on a local scal

Crystal growth is achieved by the further addition of folded polymer chain segments and only occurs for temperatures between the melting temperature Tm and the glass transition temperature Tg Higher t

Crystal formation begins at nucleation points and extends outwards into the bulk of the polymer. Nucleation starts with small, nanometer-sized areas where as a result of heat motion some chains or the

The degree of crystallinity in a crystalline material is affected not only by the chemical structure of the polymer, but by the process conditions that are used to manufacture the workpiece Crystallin
