Plastic injection molding is a highly effective manufacturing method used to produce elements by injecting molten plastic into a specially designed mold. It’s one of the most trusted processes for creating plastic parts in enormous quantities, providing accuracy, consistency, and cost-efficiency.
The procedure starts with the creation of a mold, often made from metal, shaped based on the exact design of the part. Next, plastic material is melted down into a liquid form and injected into the mold cavity under high pressure. Once filled, the mold is cooled to let the plastic solidify into its final shape. The finished product is then ejected from the mold, ready for finishing or assembly.
Today, plastic injection molding is broadly utilized across industries for producing anything from consumer goods and automotive components, medical devices, and electronic pieces, making it a cornerstone of contemporary manufacturing.
Here at Richfields, we offer a full spectrum of services to meet your exact production needs. With advanced machinery and experienced engineers, we can handle everything from simple parts to highly intricate, custom components.

When your product calls for a blend of various items or textures in a single part, overmolding is used. This specialized technique involves molding one material over another and is primarily for materials with sleek grips, multi-layered components, or combined elements. It’s commonly used for tools, electronics, medical devices, and consumer products where enhanced grip, insulation, or aesthetic layering is required.

Air assist is a plastic injection molding process designed to optimize part quality, surface texture, and material usage. As part of advanced plastic injection molding services in China, this method works by injecting highly pressurized nitrogen gas into the mold during the injection process, minimizing stress and resistance. It is highly recommended for producing larger, thinner, or more complex plastic components with smoother finishes and longer-lasting molds.
