What Is Injection Molding Side Action and How It Works

Despite the growing popularity of 3D printing, rapid injection molding remains a preferred manufacturing technique for making complex and intricate parts. We specialize in both methods here at HLH Prototypes, but for this blog, we will discuss injection molding side action and why it’s ideal for crafting parts with undercuts and complex geometries. We will explore its procedures and benefits so you can understand how it can increase your part’s functionality and precision.

What is side action in injection molding?

Injection molding side actions are essentially the movable parts sliding in the direction perpendicular to the mold’s main axis. These slides or cams make it easier to create complex features or undercuts that cannot be achieved with a regular two-part mold. Undercuts allow us to remove the molded part without damage caused by their inward-facing projections or angles.

During injection molding, the side actions work in different positions to release or develop intricate characteristics on the part. This results in components that would be impossible or challenging to achieve with traditional molding techniques. In turn, this improves manufacturing by increasing accuracy and design flexibility.

How it works

Side action rapid injection molding is ideal for making parts with advanced and intricate designs. Here’s what’s involved in the process:

• Side-action slides or cams: The main components slide sideways to produce intricate geometries. They require careful perpendicular positioning to the mold’s main parting line, creating fine details and undercuts on the part.
• Angle pins: They work with the slides or cams when the mold opens and closes.
• Mechanical or hydraulic actuators: Some molds require these systems in the moving side action elements. They guarantee consistent and accurate performance for the slides or cams.
• Ejector systems: They separate parts from the molds after forming.
• Side-action locks: These locks hold the injections in place to prevent unwanted movements that can impact part quality.

Benefits

Using side actions in rapid injection molding makes it easier to achieve complex geometries on your parts. They allow you to add more intricate functions and details to your design without compromising quality and dimensional accuracy. The direct molding action can reduce post-processing and additional machining, thereby lowering manufacturing costs and saving time.
