What Is Injection Molding?

Injection molding is among the more common parts manufacturing processes and can be used with a wide range of materials including metals, polymers, elastomers and glasses.

The process starts with a design mold that is completely encased in a machine on a line. The material that will make up the part is then heated and put into a pressurized barrel where it can be made pliable or even liquefied. This heated material is then forced - or injected - into the mold's cavity where it takes the shape of the product.

The materials are then left to cool and harden within the cavity as they take on the shape and characteristics of the mold. Parts can range from miniature items that require a high stress tolerance to large panels of cars, aircraft and other vehicles.

An interesting part of the current trend in injection molding products is that many new materials are being developed for the process. Lots of these innovations are coming about because of advances in 3D printing. New materials focus on thermoplastics that don't melt and lose their structural integrity when prepared to be injected into a mold.

The process also includes the use of controlled facilities to help regulate temperature, material use and prevent contamination risks. It's easy to enable monitoring on a line that uses injection molding, so products can be quickly managed and checked against temperature and pressure concerns.

Injection molding can be used with a wide range of materials from glass to metals, but the heat and pliability present make it a preferred choice for manufacturing work involving plastics and polymers. Plastics help ensure an error-proof production and are often able to take the intense heat of the process while retaining their strength.

These advancements and more are part of the injection molding advantages that make it perfect for creating high volumes of parts and inventory. So, what are the injection molding process advantages? Let's take a look.

What Are the Advantages of Injection Molding?


The controlled nature of injection molding makes it a process that has many different advantages. Top on the list is the ability for the line to reduce costs and defects through consistent checks and ever-advancing gear. The expertise of K S Tooling, Inc. will allow you to take advantage of that great cost savings and reliability for clean, strong products.

Some of the top money-, time- and worry-saving features of injection molding include:

  • Versatility¬†. Almost anything under the sun can be created with injection molding. From parts of your car to thousands of the plastic products you'll use this year, injection molding can create objects to fit almost any need.
  • Speedy production¬†. Injection molding allows for parts creation in fewer steps and with a tighter control on materials and waste products. Because of the clamping and injection pressures in this process, which are higher than those in transfer molding, you'll have a higher curing temperature and development. This allows you to produce a very large number of products quickly, with production cycle times as low as 15 seconds.
  • Strong parts¬†. Polymer-based injection molding allows you to include fillers in the injection molds. These can reduce the density of the polymer you're using and improve the strength of the product upon ejection. This has caused plastic injection molding to become popular for high-stress and high-heat parts.
  • Reduced labor costs¬†. Injection molding tools are typically automatic and self-gating, allowing you to start the production line and largely remain hands off. The parts themselves are usually whole and finished when the mold cools, reducing the finalization process after ejection.
  • Reduced waste¬†. Many of the materials used in injection molding, especially the polymers, can be recycled. This allows you to replenish your raw material stores with ease. You'll also have a generally reduced amount of waste products because of how controlled you can be with materials injected into a mold.
  • Multiple materials¬†. Co-injection molding procedures allow lines to insert multiple raw materials into a single mold - typically two or more types of plastics. This allows you to speed up the manufacturing process and can improve the automation capabilities of your lines.
  • Multiple styles¬†. Sometimes the same part needs to be different colors based on your own product lines, customer branding or federal regulations. Injection molding advantages include the ability to quickly shift colors and even materials used for the parts you're making.
  • Fully auto¬†. Lines are now moving into full automation with injection molding at the heart. This allows you to use multiple flows and start a whole line with minimal interference and checks.

Injection molding products are unique for each manufacturing instance so you'll see a mix of these benefits. You may see even more advantages of injection molding processes for your specific instance, especially if previous manufacturing processes have delivered inconsistent products.

Injection Molding Products

Injection Molding Products

Many of the products you use every day and even have around your desk likely have parts designed and developed through injection molding.


Many appliances use clear trays, dials, joints and housings that are developed through injection molding. Parts can weigh less than a single ounce or into the double-digit pounds. Plastic injection molds support these repeat-use products with a focus on cost-effective production and dependability.

Some plastics you're likely familiar with include the jars, containers and their lids used to keep food fresh after preparation. They also protect food in the work refrigerator, meeting the standards needed for safe consumption free from fears of chemicals leeching into the contents. These options are clearly visible on your headache medicine, the shampoo in the shower, food you buy and many home cleaning products that contain potentially harmful ingredients.

Advanced features are available as an advantage of injection molding because of the ability to use multiple raw materials and process complex shapes. These options include tamper-resistant and tamper-evident caps and lids, child-resistant lids and lids designed to be easily opened and used by senior citizens and those with impaired motor capabilities.

Home and Office

When you return home tonight and check to see if the lawn needs watering, take a look at your sprinklers and the hose and pipe couplings and fittings. Many of these parts were also likely created through injection molding. These products benefit from the injection molding advantages of mass-production for inexpensive, resilient components. If you're in the office late instead, consider the cap and body of the marker near the meeting room's whiteboard. These also use injection molding for dependability and uniform production. You've probably used hundreds of markers in your time, and the process helps ensure you've never noticed one that didn't feel right in your hand.

Vehicle Use

There are also specific areas that have higher demands where injection molding products meet the rigors of the job. The automotive and aeronautics industries are among the most demanding industries where injection molding products are used. From the decorative plastic that's sitting in your dashboard to the interior panels that must perform predictably during an accident, injection molding surrounds you every time you get behind the wheel.

Automotive parts can include your keyless entry systems, radio controls, armrest, sensors, lenses and engine parts designed to protect against heat and chemical spillage. These provide comfort, protection and can even reduce noise thanks to instrument clusters and housing designed to stifle rattling. Mix in options for sonic welding, hot stamping and more, and your automotive parts will be securely and consistently developed in a way that adheres to top standards in the industry.

Resin Flexibility

Part of the performance in the auto industry and other areas is due to the ability to use a wide range of engineering resins that are proving to be strong performers. Some of the major resin able to be used in injection molding include:

  • Acrylic
  • Acrylonitrile Butadiene Styrene (ABS)
  • Glass-filled resins
  • High Density Polyethylene (HDPE)
  • Nylon
  • PET
  • Polybutylene Terephthalate
  • PPO
  • Talc polymers
