Small Plastic Injection

small plastic injection：

thermosetting plastic
1. Definition: A polymer with crossed chain structure, whose final molecular structure is formed by chemical reaction under the action of heat and pressure.
 

2. Single-use plastic

thermoplastic
1. Thermoplastics are composed of long-chain molecules that are not intertwined with each other. Its characteristic is that when the temperature exceeds its softening temperature, it can be copied theoretically without limit by injection molding. In fact, after several processings, the characteristics of the plastic change and the plastic ages. .
 

2. Plastics commonly used in injection molding such as: PE (polyethylene), PP (polypropylene), PS (polystyrene), ABS, nylon PA.

Polymer plastic small plastic injection:
The injection molding process is to transform the solid plastic particles into a molten fluid under a certain temperature and pressure to complete the filling and molding under a certain pressure and speed. Concepts closely related to the injection molding process include: viscosity, M, pressure-volume-temperature (PVT), shear thinning effects, thermal conductivity, shrinkage of the plastic, and maximum shrinkage characteristics of the plastic. Rheology is the study of deformation (for solids) and flow (for fluids) behavior of plastics under stress. Viscosity is a measure of a fluid's resistance to flow. The higher the viscosity, the greater the resistance to flow and the more difficult it is to flow. For general thermoplastics, the viscosity is a function of plastic composition, temperature, pressure and shear rate. In terms of temperature effect, the viscosity of thermoplastics generally decreases with the increase of temperature.
