Custom Plastic Injection Molding Basics

Plastic injection molding has become a standard manufacturing process in virtually every industry. Used in scenarios demanding high-volume, mass production of various industrial components and parts, plastic injection molding from Abtec Inc. provides a customizable solution for virtually any industry or application need.

After years of experience in the industry, our team has heard virtually every question a customer could ask. Ranging from the basics, including the process of plastic injection molding and its benefits, to the specifics, such as mold production and secondary services, our team is prepared to answer any question that comes across their desk.

To help you make an informed decision on your plastic injection molding project, we’ve outlined some of the most common questions – and their answers – below.

What is plastic injection molding?

Plastic injection molding is a manufacturing process that produces parts through the heat-based injection of molten plastic materials into a mold. The molten plastic then hardens, thus creating a component or part with the exact shape and specifications of the hollow mold.

This process is used to produce high volumes of parts without sacrificing manufacturing accuracy or speed – and its benefits are catching on. In fact, the global injection molding market was valued at $283.54 billion in 2016, and demand is still on the rise.

Why use injection molding for my product?

Plastic injection molding offers unmatched versatility; plastic parts can be used across virtually any industry. The most common plastic injection molding applications are typically found in the packaging, consumables, electronics, automotive & transportation, construction, and medical device industries.

How do I know if injection molding is the right process for my product?

This depends on your product – specifically, its design, purpose and anticipated production cycle. Your budgetary considerations will also be a factor. With that in mind, components with more complex geometries and a highly repetitive manufacturing process are excellent candidates for injection molding.

How do you mold plastic?

In short, plastic injection molding works by melting the plastic, which is then subsequently exposed to high pressure and injected directly into a mold. Once the material has cooled, it will become solid and ready for release.

How does a plastic injection mold work?

First, the mold is inserted into an injection molding machine. The machine’s clamping tools ensure that it remains closed during the molding. Next, plastic is injected into the machine in form of pellets or granules and is heated until it liquefies. While under pressure, the plastic is fed into the mold, still being held within the molding machine. Once the liquid inside the mold cools, the solid-plastic product or component is ready for use.

What kind of plastics can I use?

The most common material for plastic injection molding is thermoplastic, a polymer which becomes moldable when exposed to a specific temperature and solidifies when cooled. Check out our materials page for a full listing.

How long does it take to build a mold?

Abtec’s custom tooling can produce even the most intricate molds within a limited timeframe while maintaining cost efficiency. The production timeline really depends on your specific needs, ranging from short-term aluminum tooling to the manufacturing of millions of components.

Does Abtec offer short or long production runs?

Abtec offers both high and low volume production runs for custom products at any scale. Our industry experience and state of the art, in-house technology enables us to go beyond typical custom molding and make an entire production process both efficient and scalable.
