Frequently asked questions

What is the injection molding process?

Molten plastic mixture is forced under high pressure into a custom-made mold so that the material takes the shape of the mold cavity. Once the part has been removed from the mold it is typically finished, but may require secondary operations.

What are the benefits of injection molding?

Injection molding has been around for nearly 150 years. This manufacturing process is ideal for manufacturing large quantities of identical objects due to the following key advantages:

  • High precision and accuracy
  • High efficiency
  • High flexibility
  • Consistency
  • Lower labor costs and minimal post-production work
  • Affordability
  • Sustainability

What is plastic injection molding used for?

Injection molding is used for the production of plastic parts in medium to high volume production levels. These parts come in an array different colors, shapes and sizes.

What products are injection molded?

Since injection molding represents the most common method of manufacturing plastic parts, the list of products can range from bottle caps to car parts. More complex parts are made out of a combination of two or more materials through a special process called overmolding.

What material is used in injection molding?

Special varieties of plastic are typically used for injection molding which include many types such as: polycarbonate, acrylonitrile butadiene styrene (ABS), nylon, etc. Learn more about various plastics used in injection molding at our materials page.

How are injection molds made?

A custom mold is designed using computer aided design (CAD) software or similar, is machined with different disciplines out of solid metal and generally has two halves that will come together during the mold assembly process.

An injection mold is essentially a hollow metal block. Cavities within the mold are filled through gates and runners, and once filled with plastic, will produce the desired part.

How long do injection molds last?

The life of a mold is directly related to the type of mold, the type of material injected into it, and the number of parts produced.

A mold life expectancy can last between hundreds and millions of parts if properly constructed and maintained. The application (i.e.: prototyping, production) usually dictates the mold’s endurance.

What is custom injection molding?

Custom injection molding is a service providing custom molds and/or custom parts from a mold for the customer at small, medium, and large volumes.

Who invented injection molding?

American inventors, brothers Isaiah and John Wesley Hyatt patented the very first injection molding machine in 1872. Despite its seemingly simple original design, this machine made the manufacturing process infinitely easier. It also served as the prototype for the sophisticated injection molding machines that we use nowadays, since the principle is much the same to this day.
