Increase temperature of mould

Charging speed increase                     product is easy to sink

Process cycle period extend                  impact strength decrease lightly

Surface bright of product get better            dimensional stability of product improved

Shrinkage rate of product increase             temperature of thermal deformation improved

Increase Injection pressure

Charging speed increase

Process cycle period become shorter            product is easy to distort

Weight of product increase                    molding scrap is easy to appear

Void inside decrease                         spray trace is obvious

Strength of product improved                  burned phenomenon is easy to occur

 

Increase temperature of charging barrel

Charging speed increase

Process cycle period extend               burned phenomenon is easy to occur

Surface bright of product get better         Void inside is easy to form

Indentation of product is easy appear       Shrinkage rate of product increase 

 

Increase injection speed

Process cycle period become shorter       Surface bright of product get better
