Consider whether the part meets the injection molding capability. Determine if the identified resin is suitable for the particular design of the part. Perform a 5-gallon Pet Preform mold process analysis.
Most of the work is done during the injection mold design phase.
These considerations play an important role in determining the design of the injection mold. Since the research was completed during the design and concept phases, the most successful projects were launched without any fuss. Everyone from engineers to resin suppliers, molding suppliers, etc. will play an important role in solving these problems.
Designers, engineers and other relevant team members will prove to be the key to the successful development and design of plastic injection molded parts. The main areas of focus in the design phase should be the correct design of the plastic part, the correct selection of the part design material, and the processing conditions required for plastic injection molding.
You can control costs by designing a part that moves up and down or straight pull motion. The straight pull mold allows the two halves of the mold to be separated from each other without the plastic obstructing the path of the metal in the direction of stretching. This path blockage may be caused by undercuts on the part. Corresponding mold movements such as core pulling or caming are necessary. The action in the mold will have a huge impact on the overall cost of the mold.
Fight against defects
A uniform wall thickness prevents defects. This is the basic requirement for effective injection molding of Pet Bottle Mould. Consider the fact that plastic shrinks during cooling. Such shrinkage can cause defects such as warpage, dent mark stress, voids, and the like. The plastic resin is cured in a mold close to the outside of the part. This is the part closest to the surface of the mold. Sections of a relatively large part of the circumference are often pulled inward, creating voids, dents or stresses. The narrow portion cools faster than the thick portion. This can result in an increase in stress between the thick section and the thin section, eventually distorting the part.
