• Core: The core is the counterpart of the cavity and creates the internal features of the plastic part. It defines the inner shape and design elements of the molded product.

• Runner System: The runner system is a network of channels that guide the molten plastic from the injection molding machine into the cavity. It consists of a sprue (the main channel from the injection machine) and various runners that distribute the plastic to multiple cavities in multi-cavity molds.

• Gate: The gate is the point where the molten plastic enters the cavity. It controls the flow and is designed to solidify quickly after injection to prevent excessive material waste.

• Ejector Pins: Ejector pins are used to push the finished part out of the mold once it has cooled and solidified. They are an essential part of the ejection system.

• Cooling System: The cooling system includes cooling channels or water passages within the mold that help regulate the temperature during the cooling phase. Proper cooling is essential for achieving high-quality parts and short cycle times.

• Venting System: The venting system allows air or gases to escape from the mold during the injection process. Proper venting prevents air traps and defects in the final product.

• Mold Base: The mold base provides a sturdy foundation for all the components and ensures proper alignment and stability during the molding process.

• Guide Pins and Bushings: Guide pins and bushings help maintain the alignment of the mold halves and ensure accurate part ejection and re-closure of the mold.

• Heating System (optional): In some cases, molds may include a heating system to control the temperature of the mold surfaces, especially for molds used with thermosetting plastics.

Injection mold grade classification

Types of Injection Molds Based on Feeding System

Hot Runner Mold: In a hot runner mold, the runner system remains at an elevated temperature even when the mold is open. This reduces material waste, as there is no need to remove and regrind cold runners between cycles. Hot runner molds are suitable for high-volume production and reduce production costs.

Cold Runner Mold: In a cold runner mold, the runner system cools and solidifies between cycles, resulting in more material waste and increased production costs. However, cold runner molds are often more cost-effective for smaller production runs or when using materials with higher material costs.

Types of Injection Molds Based on the Number of Cavities

Single Cavity Mold: A single cavity mold creates one part per injection cycle. It is suitable for low-volume production or when the part design is complex, requiring more time and precision for each cycle.

Multiple Cavity Mold: This type of mold has two or more cavities, allowing for the simultaneous production of multiple parts in each injection cycle. Multiple cavity molds are ideal for high-volume production, maximizing efficiency and reducing cycle times.

Family Mold: A family mold contains multiple cavities, producing different parts or variations of a part in a single injection cycle. It is commonly used when different parts share similar features or when producing components for an assembly.

Types of Injection Molds Based on Mold Plate

Two-Plate Mold: A two-plate mold consists of two main halves (plates) that separate to eject the part. It is the simplest and most common type of mold used for single-cavity and multi-cavity molds.

Three-Plate Mold: A three-plate mold has an additional plate, called a stripper plate, between the cavity and core plates. The stripper plate moves to separate the part from the runner system, which is beneficial for complex part geometries or parts with undercuts.

Stack Mold: A stack mold utilizes multiple parting planes and can produce twice the number of parts in the same injection cycle. It is ideal for high-volume production and when space is limited.

Types of Injection Molds Based on Part Complexity

• Simple Mold: Simple molds are designed for parts with straightforward geometries and minimal undercuts or intricate features. They are generally less complex and cost-effective for producing basic shapes and designs.

• Complex Mold: Complex molds are required for parts with intricate designs, multiple undercuts, and intricate features. These molds are more challenging to manufacture and often involve advanced engineering and precise machining to achieve the desired part shape.

• Multi-Shot Mold: A multi-shot mold is used to create parts with multiple materials or colors in a single injection cycle. It involves multiple injections of different materials or colors into the same mold to produce a finished part with various integrated components.

• Gas-Assisted Mold: In gas-assisted molding, nitrogen or gas is injected into the mold to displace the molten plastic, creating hollow sections within the part. This technique is used to produce parts with thick sections or to achieve a specific design, reducing material usage and improving part strength.

• In-Mold Decoration (IMD) Mold: An IMD mold incorporates decorative elements, such as graphics or labels, directly into the molded part during the injection molding process. This eliminates the need for additional post-production steps and enhances the aesthetics of the final product.

• Thin-Wall Mold: Thin-wall molds are designed to produce parts with extremely thin walls, typically less than 1mm. They require precise cooling and material flow control to prevent defects and maintain part integrity.

These different types of injection molds provide manufacturers with flexibility and options to meet various production needs, optimize efficiency, and produce high-quality plastic parts.
