There are several factors that will determine your injection molding cost, including:

  • Part size
  • Complexity
  • Material
  • Quantities


Material selection is another consideration in determining the cost of injection molded plastic parts. In general, the plastic used to create the product is determined by what the product will be used for. Different plastic materials have different properties and an experienced manufacturer can help determine the best plastic for the job. Commonly used plastic materials include:

  • Polyethylene
  • Polypropylene 
  • ABS
  • Polystyrene
  • Nylon
  • Polycarbonate


If you have a target injection molding cost, tell your mold builder. They can design the mold accordingly and plan for the right number of cavities to achieve that price. The more cavities (or parts made per cycle), the less expensive the parts will be, also allowing for higher output.

How much does it cost to make a plastic mold? Wondering about custom injection molding costs? look no further. See below for some plastic injection molding cost examples.

A small, single cavity plastic injection mold usually costs between $1,000 and $5,000. Very large or complex molds may cost as much as $80,000 or more. On average, a typical mold costs $12,000.
