Test sample processing

Relying on professional R & D team, professional mold flow analysis and process research team, as well as advanced molding processing equipment, we can prepare a complete set of polymer samples on the basis of ensuring the stability and uniformity of samples.There are 35 sets of injection molding machines and 50 sets of moulds in our center, so that we can prepare combustion plates, large shrinkage, semi-gloss and semi-dermatoglyphic plates, spiral lines, blasting boxes, high light plates, fan blades, high-precision mechanical moulds, ASTM mechanical splines, GB mechanical splines, ISO mechanical splines and so on.

Mold flow analysis

We have a full set of mold flow analysis data testing and analysis capabilities, so that we can obtain stress-strain curve, tensile modulus, Poisson's ratio, PVT, CLTE, specific heat, thermal conductivity, viscosity and other material characteristics parameters. Related analysis files can be imported into the mold flow analysis software to accuratelly simulate plastic injection molding process,  provide optimization suggestions and improveprograms, which improving product quality and production efficiency.

Viscosity: The viscosity data refers to the material viscosity at different temperatures and shear rates, which affects the filling analysis results of the material and has an impact on the prediction of filling pressure and locking force

PVT: Specific volume data refers to the change in specific volume of a material under different pressures and temperatures, which affects the results of pressure holding analysis and has an impact on the prediction of shrinkage marks and shrinkage rates

Heat Capacity: Specific heat is related to cooling analysis and affects wavefront temperature changes, forming cycles, etc

Mechanical Properties: Mechanical properties include elastic modulus, Poisson's ratio, CLTE, etc., which affect the accuracy of warping analysis

Crystallinity: The inherent characteristic of crystalline materials, and the cooling rate can affect crystallinity. It is used to correct PVT and affect the accuracy of warping

Viscoelasticity: Parameters required for flow viscoelasticity and solid viscoelasticity, tiger skin patterns, snake like patterns, optical analysis, and stress release analysis in thermal processes

Thermal conductivity: The thermal conductivity is related to cooling analysis and affects wavefront temperature changes, forming cycles, etc
