When the design requirements need higher flexibility, or the printed products cannot directly
molded, packaging industry commonly use prototype processing label instead of printing job .
The labels usually adopt printed polypropylene film, thickness is commonly tenths of millimeters .
The advantage of prototype processing label is combined the downstream process with injection
molding steps directly .The defect is due to the heat insulation effect of label, will slightly
extended molding cycle.
First ,during the stripping process of previous product , make use of the complex mechanical arm
end technology insert the label into the injection mold.Then fix the label into the appropriate
location of the model firmly through electrostatic adsorption or vacuum negative pressure.
The requirements of the prototype processing label is almost the same with thin-wall
injection molding .
Prototype processing decoration request very low to the injection molding machine. Model
design, automation technology and decorative membrane insert production is mainly facing
challenge. According to the requirement of the prototype processing decoration craft , the
injection molding machine can adopt cascade control system, adjust the equipments
through the time ,screw stroke, injection pressure or prototype processing pressure. Under
normal conditions,prototype processing decorations can adopt low pressure processing
technology, such as foam injection or injection compression molding.
