    What You Need To Know About Tooling and Mold Making

    When it comes to manufacturing, you want to ensure that you have the highest-quality products to achieve the best result. Here's what you need to know about tooling and mold making.

    What is Injection Molding?

    Before you understand tooling, you need to know the basics about injection molding. This process involves injecting molten plastic into a previously designed mold, where it cools and hardens into a specific shape. The injection mold is composed of two parts: the core, which is the internal shape of the molding, and the cavity, which is the external shape. Once the piece is removed from the mold, it can be packaged as the final product or sent on for further finishing.

    What is Tooling?

    Tooling is a complex process that refers to designing the mold and its components. It's important that this procedure is carried out with extreme precision and care, as your final product will only be as good as your original mold. There are six main steps in the tooling process:

    1. Manufacturability: In the first stage, engineers work together to determine mold materials, resin characteristics and any other product specifications.
    2. Design: Next, preliminary models are constructed to determine the size of steel needed and what the mold will look like.
    3. Final Design Specifications: The individual in charge of tooling receives the design specifications and makes any final modifications.
    4. Primary and Secondary Tool Construction: The tool drawings are completed, and various meetings are held to discuss construction standards and inspect the completed mold.
    5. Initial Sample Creation: Once the manufacturing department has decided on the best molding process, initial sampling is carried out.
    6. Final Tool Corrections: In the last step of the tooling process, necessary adjustments are made and the parts are submitted to the customer. Once the customer approves, the production process can begin.

    Should You Use Steel or Aluminum?

    Although most molds are made from steel, there are also some benefits of using aluminum. Aluminum cools rapidly and is easier to operate on, which increases production rates and therefore makes it an attractive option for tooling and mold making. In addition, it's typically much more affordable than steel. However, because aluminum is softer than steel, it's more susceptible to wear over time and can also be more difficult to weld and maintain. This is why aluminum is typically used for prototypes or simpler parts.

    On the other hand, steel molds are more durable and have a higher production rate, making them a great choice for complex parts. Hardened steel is the least susceptible to wear as compared to pre-hardened steel, but it's important to keep in mind that harder steel can be more brittle and therefore can crack if impacted.

    As you can see, tooling and mold making is an intricate process that requires the help of a reliable and experienced professional.
