What is Large Part Injection Molding?

Large part injection molding is a type of injection molding process used to produce sizable plastic components. Like all injection molding techniques, it works by injecting molten plastic material into a mold cavity under intense heat and pressure. As the plastic solidifies, it hardens into the shape of the mold.

Large part injection molding differs from conventional injection molding in the size of parts it can produce. Using larger machines and molds, this technique can create massive components measuring several feet across with relative ease.

Large Part Injection Molding Process

While extremes of size and force are used, the underlying process remains similar to conventional injection molding. Here is the sequence:

1. Clamping

To start, the two halves of the mold are closed and pressed together with great force by the machine’s platens. Guide rods ensure proper alignment as the mold closes.

2. Injection

Next, the injection unit melts plastic resin and injects it into the mold through the sprue. The liquid plastic flows through runners that direct it into every crevice of the cavity.

3. Cooling

Channels cut into the tooling circulate temperature-regulated water, cooling the plastic. As it solidifies, the parts shrink slightly away from the mold walls.

4. Ejection

Lastly, the platen opens, the parts are ejected using pins, and the mold closes to repeat the cycle.

How We Optimize Your Large Plastic Parts Project?

Injection Molding Gas Assist: Use pressurized gas to make stronger, better-looking parts.

Foam Injection Molding: Structural foam molding is a way to make plastic parts using low pressure. Melted plastic is mixed with nitrogen or a special chemical to make foam. Then, the plastic is pushed into the mold. The gas or foam fills the mold. As the part cools, the gas makes it stronger and prevents dents.

In-Mold Label: An in-mold label can also be called an in-mold color or in-mold decoration. The PET is used as the carrier. The ink pattern is printed, and the adhesive is solidified. Then, it is heated and baked for pressing and trimming. The PET is put into the mold and filled with plastic. The adhesive melts at high temperatures and sticks the PET sheet with the ink pattern layer to the plastic.

Our Large Part Injection Molding Service Process

At Baiwe Molding, we follow a well-defined process to ensure the success of every large part injection molding project. Our comprehensive service process is designed to meet high-quality standards and deliver on time. Here’s how we work with you from start to finish:

1. Consultation and Project Analysis

We begin by discussing your project requirements, including material selection, part specifications, and any special needs. Our team performs an initial analysis to determine the feasibility and best approach for your project.

2. 3D Mold Design and Prototyping

Based on the project requirements, our engineers design a custom 3D mold that meets exact specifications. We also create prototypes when necessary, allowing you to review and test a sample of the final product before moving forward.

3. DFM (Design for Manufacturing) Analysis

Before production, we conduct a DFM analysis to assess any potential risks and improve mold design. This step helps us optimize production efficiency and reduce material waste, ultimately saving you time and cost.

4. Injection Molding Production

Once the mold is finalized, we proceed with the injection molding process. With our high-capacity machines, we can handle large-scale production efficiently, maintaining precision and consistency across all parts.

5. Quality Inspection and Testing

To start, the two halves of the mold are closed and pressed together with great force by the machine’s platens. Guide rods ensure proper alignment as the mold closes.

6. Assembly and Finishing (if needed)

For projects that require additional assembly or finishing, our team performs these tasks according to your specifications, ensuring that each product is ready for use upon delivery.

7. Packaging and Delivery

We handle the safe packaging and logistics to ensure your parts are delivered on time and in perfect condition, whether for domestic or international shipment.
