Types of Injection Molds: Master Unit Die, Full Chase Tools, and More

In the world of manufacturing, injection molding is a popular technique for creating high-quality plastic parts. The process involves injecting molten plastic into a mold, which then cools and solidifies to form the desired shape. There are various types of injection molds available, each with its own advantages and disadvantages. Here, the Abtec team will explain the different types of injection molds, including Master Unit Die, Full Chase Tools, and more.

Full Chase Tools

Full Chase Tools are a type of injection mold that is designed for high-volume production. They consist of a mold base and a set of interchangeable inserts, allowing Abtec, Inc. to produce multiple parts with the same tooling. This makes them a cost-effective option for large-scale manufacturing as it reduces tooling costs and minimizes downtime during production.

Master Unit Die

The Master Unit Die (MUD) is another popular type of injection mold that is designed for small to medium-sized production runs. It consists of a unit die that houses multiple cavities, allowing manufacturers to produce multiple parts simultaneously. This type of mold is particularly useful for producing complex parts, as it can accommodate a variety of geometries and sizes.

Advantages of Master Unit Die

  1. Efficient production: MUDs allow for the simultaneous production of multiple parts, reducing cycle time and increasing overall efficiency.
  2. Versatility: Master Unit Dies can accommodate a wide range of part geometries and sizes, making them suitable for a variety of applications.
  3. Reduced tooling costs: MUDs are a cost-effective solution for small to medium production runs, as they require less tooling investment compared to other types of injection molds.

Plastic Injection Mold Design

A crucial aspect of the injection molding process is the design of the mold itself. The plastic injection mold design plays a significant role in determining the quality and functionality of the final molded part. Factors to consider during the design process include the type of plastic material, the desired part geometry, and the requirements of the production process.

Hot Runner Systems

One important consideration in plastic injection mold design is the use of hot runner systems. These systems consist of heated channels that guide the molten plastic from the injection unit to the cavities within the mold. Hot runner systems offer several advantages, including reduced cycle time, improved part quality, and reduced waste.

Modular Unit Die

Another option for injection mold design is the Modular Unit Die (MUD), which is similar to the Master Unit Die but offers greater flexibility in terms of mold configuration. Modular Unit Dies consist of interchangeable components and quick change, to reduce set-up and run times. Making this system an ideal choice for versatility in the production process.
