cosmetic terms

Many times we will come across terms and abbreviations in the cosmetic world that don’t quite make sense! Below is a guide to help clarify these commonly used cosmetic packaging terms and abbreviations.

What does it mean?

  • Cavity – Shaped areas in a mold, usually identical side-by-side designs that can produce multiples of the same part in a single cycle.
  • Blow molding – In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and stretch blow molding. The blow molding process begins with melting down the plastic and forming it into a parison or preform. The parison is a tube-like piece of plastic with a hole in one end in which compressed air can pass through. The parison is then clamped into a mold and air is pumped into it. The air pressure then pushes the plastic out to match the mold. Once the plastic has cooled and hardened the mold opens up and the part is ejected.
  • Flow marks – Wavy surface marks on a resin molding due to flow of material into the mold. Can also be caused when additive is in resin such as pearl coloring.
  • Injection molding – A molding process in which resin is heated in a barrel and then injected into a mold by a reciprocating screw. The resin then cools in the mold and is ejected as a solid part.
  • Sink mark – A surface blemish in which the outer wall is depressed in areas of the plastic product. Sink marks are often caused by variations in material thickness.
  • Tooling – The process of creating a mold used in the manufacturing process that gives shape to component parts.
