Understanding Multi-Cavity Injection Molding

 

1.1 What Is Multi-Cavity Injection Molding?

Multi-cavity injection molding, also known as multiple impression molding, is a process in which a mold is designed with several cavities to produce multiple parts simultaneously with a single shot of molten plastic.

• Each cavity is engineered to produce an identical component, maximizing output per cycle.

• This method significantly increases production efficiency, making it ideal for mass production.

• In contrast to single-cavity tooling—where each shot yields one part—multi-cavity molds can contain anywhere from 2 to 128 cavities, depending on part size and customer requirements.

1.2 The Role of Injection Molding New Technology

Advances in injection molding new technology have enabled the production of highly complex multi-cavity molds with precise control over material flow and pressure distribution.

• Innovative CAD/CAM software and high precision CNC machining are integral to designing these molds.

• Enhanced simulation tools allow engineers to optimize gate, sprue, and runner configurations for even filling.

• With this technology, manufacturers achieve superior quality, reduced cycle times, and lower per-part costs.
