Plastic injection moulding is a key manufacturing process in the production of various plastic products, ranging from small and intricate components to large and complex parts. In this process, molten plastic material is injected into a mold cavity, where it cools and solidifies to form the desired shape. "GoodBo Mould" is a leading company in the plastic injection moulding industry, specializing in providing high-quality molds for various industries. In this article, we will discuss the application and processing technology of plastic injection mould, with the different components of a mold and the important factors to consider during the process.
Key Applications:
Plastic injection moulding is used in various industries, including automotive, consumer electronics, medical devices, and household appliances. Its versatility and cost-effectiveness make it a preferred choice for the production of plastic parts in large quantities.
Automotive industry
It is widely used in the automotive industry for producing parts such as bumpers, dashboards, and interior trim. These plastic parts are durable, lightweight, and have excellent strength-to-weight ratio, making them ideal for use in vehicles.
Consumer electronics
The electronics industry relies heavily on plastic injection moulding for the production of components like phone cases, computer parts, and TV housings. This process allows for the precise and intricate design of these components, ensuring a perfect fit for electronic devices.
Medical devices
With the increasing demand for medical devices, plastic injection moulding has become a crucial process for the production of syringes, medical trays, and other equipment. This process meets the strict quality and safety requirements needed for medical devices.

Different components of the mold
Components of a Mold
A plastic injection mold is composed of several key components, each playing a crucial role in the success of the process. These components include the mold cavity, mold base, mold gate, mold sprue, mold runner, and mold cooling system.
Mold Cavity
The mold cavity is the part of the mold that forms the shape and surface of the final plastic product. It is designed to ensure that the molten plastic material fills every corner of the cavity and maintains the desired shape during the cooling process. The number and size of mold cavities can vary depending on the type and size of the product being produced.
Mold Base
The mold base is the bottom part of the mold that holds all the other components in place. It is typically made of steel or aluminum and provides the necessary support for the entire mould structure. The quality of the mold base plays a critical role in the overall quality and durability of the mold.
Mold Gate and Sprue
A mold gate is the entrance through which the molten plastic material is injected into the mold cavity. The size and location of the gate are carefully determined to ensure proper filling of the cavity without causing any defects in the final product. The mold sprue, on the other hand, is the channel that directs the molten plastic material from the nozzle of the injection molding machine to the mold cavity. A well-designed gate and sprue are crucial in the successful production of high-quality plastic products.
Mold Runner
The mold runner is the channel that connects the sprue to the mold cavity or multiple cavities in a multi-cavity mold. It allows for the flow of molten plastic material and facilitates the cooling process. The size and design of the runner are important in maintaining uniform mold filling and minimizing mold shrinkage.
Mold Cooling System
The mold cooling system is an essential component of a plastic injection mold. It consists of channels or passages through which cooling water or oil is circulated to maintain the mold at the desired temperature. Proper cooling is critical in ensuring that the plastic material solidifies evenly and maintains the desired shape.
Overmolding
Overmolding is a technique where one material is molded onto another previously molded part. This is achieved by using multiple mold cavities in a single mold. Overmolding allows for the production of more complex components with different materials and colors. It also helps to reduce assembly time and costs.
Important Factors to Consider
During the plastic injection moulding process, several factors must be considered to ensure the production of high-quality products. These factors include:
Mold Shrinkage
Mold shrinkage is the change in the dimensions of the plastic product after it cools and solidifies. It occurs due to the cooling and solidification of the molten plastic material, which causes it to shrink in volume. It is essential to consider mold shrinkage during the design process to ensure that the final product meets the required dimensional specifications.
Tolerance Accuracy
Tolerance accuracy refers to the range within which a product's dimensions must fall to meet the desired specifications. It is crucial to maintain tight tolerance accuracy in the production of plastic products to ensure proper fit and function. This is achieved by careful design of the mold and the use of high-precision machining techniques.
Injection Molding Pressure
The injection molding pressure is the force applied by the injection molding machine to inject the molten plastic material into the mold cavity. The pressure must be carefully controlled to prevent damage to the mold and ensure proper filling of the cavity without causing any defects in the final product.
Mold Maintenance and Repair Requirements
A plastic injection mold must be regularly maintained and repaired to ensure its longevity and consistent production of high-quality products. Routine maintenance includes cleaning, lubrication, and inspection of all components. Any damages or wear and tear must be repaired promptly to avoid production delays and costly replacements.
