Shrinkage of plastic part is the reduction in size of a plastic component during cooling after molding.
Shrinkage occurs due to the cooling process after the plastic part is molded.
Factors affecting shrinkage include material type, mold design, processing conditions, and part geometry.
Shrinkage is typically expressed as a percentage of the original dimensions.
Compensating for shrinkage is important in designing molds an...

Shut off angle in molding refers to the angle at which the mold halves meet and close to form a complete part.
Shut off angle is crucial for ensuring proper part ejection and preventing flash formation.
It is typically between 0.5 to 3 degrees, depending on the material and part design.
A larger shut off angle may be required for parts with deep cavities or complex geometries.
Improper shut off angle can lead to part defec
In pp plastic material, coating is preferred over painting for better adhesion and durability.
Coating is commonly used on PP plastic material for better adhesion and durability
Painting is less preferred on PP plastic due to poor adhesion and durability
Examples of coatings for PP plastic include polypropylene-specific primers and adhesion promoters
Undercut angle in plastic is the angle between the side wall of a mold and the vertical direction.
Undercut angle is important in plastic injection molding to ensure proper release of the part from the mold.
It is typically measured in degrees and affects the draft angle required for the mold.
A larger undercut angle allows for easier part ejection but may require more complex mold design.
Examples of parts with undercut a...
Warpage and sink marks are common defects in plastic parts caused by uneven cooling. Prevention methods include proper gate design, cooling system optimization, and material selection.
Warpage is the deformation of a plastic part due to uneven cooling, leading to dimensional inaccuracies.
Sink marks are depressions on the surface of a plastic part caused by uneven cooling and shrinkage.
Prevention methods include proper g...
