What is Injection Molding

Have you ever wondered what toys, toothbrushes, and plastic packaging have in common? They’re all made using a specialized manufacturing process known as injection molding. During injection molding, molten plastic (usually a thermoplastic) is injected into custom molds made from metal, such as steel or aluminum. These molds form the plastic into the manufacturer’s desired shape, with the mold cavities creating hollow chambers in the plastic where necessary. The plastic component is then cooled and released from the mold.

Injection molding plays a crucial role in modern life; without it, it would be impossible to affordably mass-produce plastic products. The efficiency and precision of injection molding allows manufacturers to reproduce the same part thousands – or even millions – of times without error. Many essential items, including medical supplies and food packaging, are produced using custom injection molding.

Mold Making Process

  1. Material selection.
    The expert product designers at Delmo can help you analyze different injection molding materials, ultimately finding the best fit for your product. To verify that we’ve chosen the right material, we then create rapid prototypes and conduct thorough product tests.
  2. Quantity planning.
    Next, our team will discuss the number of products needed by the client. Determining product quantity is essential to choosing the correct type of mold; e.g., a prototype mold or a high-volume production mold.
  3. Mold flow analysis.
    Before making a mold, we perform what’s known as “mold flow analysis” using advanced mold flow analysis software, which generates a full report. This report provides information on crucial factors like cooling channel efficiency and the accuracy of the final product. Based on this report, we can troubleshoot any potential issues ahead of time, eliminating the risk of manufacturing errors.
  4. Mold creation.
    Our specialists use the latest CAM software and NC and CNC machine systems to efficiently design and produce durable, accurate, detailed metal molds. Once the molds have been created, we help our clients test, set up, and use their new molds.

Injection Molding FAQs

What plastics can be used with injection molding?

Virtually any type of thermodynamic plastic can be used with injection molding, and several plastics may be combined together to create the best material for your project. The ten most popular plastics used for injection molding are as follows:

  • acrylic (PMMA)
  • acrylonitrile butadiene styrene (ABS)
  • nylon (polyamide, PA)
  • polycarbonate (PC)
  • polyethylene (PE)
  • polyoxymethylene (POM)
  • polypropylene (PP)
  • polystyrene (PS)
  • thermoplastic elastomer (TPE)
  • thermoplastic polyurethane (TPU)
What certifications should you look for in an injection molding company?
The certifications required by injection molding companies vary by industry. However, a useful general credential to look for is ISO 9001 certification, which verifies that a manufacturing company consistently produces reliable, high-quality products.
What happens during injection molding?

First, plastic pellets are melted down into a liquid. Then, the liquid plastic is fed into a metal mold, where it cools and solidifies into the desired shape.

Why should I use injection molding?
Injection molding has multiple benefits that make it ideally suited to mass-producing plastic products. Injection molding is highly accurate, allowing large numbers of products (potentially into the millions) to be created with optimal detail and minimal waste. This creates an “economy of scale” that greatly lowers the price of each product, ensuring affordability for both manufacturers and consumers. Injection molded products can also be brought to market quickly because they typically don’t require finishing or refinement; as long as you use high-quality molds, your products will emerge from the mold with a smooth, attractive finish.
How quickly can parts be produced with injection molding?
Many different variables influence how quickly parts can be manufactured with injection molding, such as the complexity and intended use of the final product. However, in many cases, it’s possible to design a custom injection mold in one to two months. Once your mold is up and running, you can begin manufacturing parts immediately.
How do I know if injection molding is the right manufacturing process for my product?
Multiple criteria determine whether or not injection molding is the best choice for a product. Your product’s dimensions, intended application, and your budget, for example, are important factors when considering injection molding. Our experts can help advise you on whether or not injection molding is right for your project.
