Product Managers Guide to Plastic Injection Molding

As a product manager, one of the most important decisions you’ll make is choosing the right manufacturing process for your product. One option that you may consider is plastic injection molding, which is a popular choice for producing high-volume, identical parts. However, the process of working with a plastic injection molding company can be complex and time-consuming. In this blog post, we’ll take a look at the necessary steps involved in getting parts fabricated by a plastic injection molding company, such as Laszeray Technology.

Step 1: Product Design

The first step is to create a detailed product design. This is a critical step because it lays the foundation for the entire manufacturing process. Your product design should include detailed drawings, specifications, and a bill of materials. These documents will be used by the plastic injection molding company to create a mold and produce the parts. The more detailed and accurate your design is, the fewer problems you will have during the manufacturing process.

Step 2: Selecting the Right Injection Molding Company

The next step is to select the right plastic injection molding company. This is an important decision because the quality of the parts produced will depend on the company’s capabilities and experience. When evaluating potential companies, it’s important to consider factors such as their equipment, capabilities, lead times, and pricing. Additionally, you should ask for references and samples of their work to ensure they have experience producing parts similar to yours.

Step 3: Create the Mold

Once you have selected a plastic injection molding company, the next step is to create the mold. The mold is the tool that is used to produce the parts. It is typically made of steel or aluminum and is designed to the specifications of your product design. The mold creation process can take several weeks to several months, depending on the complexity of the design.

Step 4: Production

After the mold is created, it’s time to produce the parts. This is the process of injecting molten plastic into the mold and allowing it to cool and solidify. This process is typically automated and can produce hundreds or even thousands of parts in a single run. However, it’s important to note that the first parts produced may not be perfect and may require adjustments to the mold. This is known as the “mold trial” phase, and it’s an important step in the process to ensure that the final parts meet your specifications.

Once the mold is optimized, the plastic injection molding company will begin producing the parts in volume. This is the time when you need to consider your inventory management, to ensure that you have enough parts to meet your demand. This is also the time when you need to consider your logistics and distribution, as the parts need to be shipped to your warehouse or directly to your customers.

Step 5: Quality Assurance

After the parts have been produced, it’s important to conduct a final quality check. This includes inspecting the parts for defects and ensuring that they meet your specifications. If there are any problems, you should work with the plastic injection molding company to resolve them.

Step 6: Assembly

Finally, it’s time to start using your parts in your final assembly process. This is where you’ll be putting all the parts together to make your final product. This is also the time when you need to consider your packaging and labeling requirements.

In summary, getting parts fabricated by a plastic injection molding company involves several steps, including creating a detailed product design, selecting the right plastic injection molding company, creating the mold, producing the parts, optimizing the mold, conducting a final quality check, and using the parts in your final assembly process. Each step is critical to the success of the project and requires careful planning and execution. By following these steps, you can ensure that your parts are produced on time, to the highest quality, and at a competitive price.
