Plastic Part Design and Manufacturability

Plastic Injection Molding

There are four key factors that go into making a high-quality plastic injection molded part: part design, tool building, material selection and manufacturing.

In this article, we will start at the beginning of the process, with the part design.

The process of plastic injection molding is designed to produce precision parts at a low cost.  The part design must be developed to maximize the efficiency inherent in high-volume molding.  With the right design, parts can be made consistently and with quality.  Without a good design, costly processing mistakes can be made.

50 Shades of Grey Plastic Parts

Plastic Injection Molding

How do you achieve just the right shade of grey in your plastic part?  It’s all in the masterbatch.  A masterbatch is a concentrated mixture of pigments and/or additives encapsulated during a heat process into a carrier resin*. The resulting product is used to color raw polymer materials and provide other desired characteristics to the final part such as UV light resistance, flame retardants, slip agents and anti-stat agents.

We all know the importance color plays in our lives.  And for manufacturers, getting the color right is an integral part of product quality.   Unlike metal or other base materials, plastics lend themselves to a wide array of colors and additives.  They are used in everything from bottle caps to medical devices.  Each plastic application requires specific properties from the chosen polymer.

When to Use a Precision Custom Plastic Injection Molder

Plastic Injection Molding

Like anything in life, there are degrees of perfection. This is true in plastic injection molding.  Some molders specialize in lower volume parts that don’t require a high level of detail or precision.  This type of manufacturing may be suitable as some projects don’t require a perfect part based on the application.

Take disposable cutlery for instance.  Because of its “use and toss” status in this world, plastic knives and forks don’t need to maintain a high level of perfection.  They can have a bit of flash around the perimeter, and no one gives it a second thought.

The Pros and Cons of Cold Versus Hot Runner Molds

Plastic Injection Molds and Presses

Every plastic part starts in a mold.   Molds are classified into two main types, cold runner and hot runner.  Each has its advantages and disadvantages.   Your plastic injection molder will be able to give you the costs and benefits of using these different systems.  However, by understanding the key differences of these technologies, you can have a more educated discussion on the type of mold that would best fit your project.

Earth Day is here to stay

Sustainability in Manufacturing

Each year, we stop to remember the humble beginnings of Earth Day and how the movement has grown over the past forty-four years since its inception.  Back in the early days, the Vietnam War nearly consumed the American conscious.  Not much room remained for environmental causes.

Can Manufacturing Companies Recycle Effectively?

American Manufacturing and Products

Excuses, excuses, excuses.

“We can’t ask our employees to sort their trash.”

“We don’t recycle because it all ends up in the landfill anyway.”

“It could end up costing us time and money.”

There is a long list of excuses often espoused by organizations to justify their hesitancy to become involved in recycling programs.  Most often these excuses are based on old myths, technologies and processes.  Today, recycling and waste collection companies have refined their procedures to offer hassle free, mutually beneficial recycling relationships with businesses throughout the country.

One stream or two?

Gone are the days of containers for every form of trash.  Many waste companies now offer either dual-stream or single stream recycling.  Dual stream recycling separates paper from all other forms of recyclable material.  This method helps increase compliance and collection speeds.  Single stream recycling was introduced in the late 1990’s partly in response low recycling rates within communities and organizations.  This method allows all recyclable material to go into one container.  The material is sent to a sorting facility. Using lasers, conveyor belts and other equipment; various plastics, metals and paper are sorted and baled. 

Make electricity not trash.

In Europe, countries have been creating energy from trash for a very long time.  In this country, the practice is fairly recent, and we are capitalizing on the innovations and successes of our European allies.  Many trash-to-steam plants have been built across the country.  These plants take just about any material, burn it at extremely high temperatures, heat water which converts to steam.  The steam is piped into generators to create electricity.
