Vertical Injection Molding Machine: Compact and Versatile for Insert Molding and Multi-Material Applications

What is a Vertical Injection Molding Machine?

A vertical injection molding machine features a vertical clamping unit, making it ideal for insert molding (metal/plastic hybrids) and overmolding. Its space-saving design suits industries like automotive, electronics, and consumer goods.

Types & Configurations

1. Standard Vertical Presses
   • For insert molding of electrical contacts or threaded inserts.
2. Two-Shot Vertical Machines
   • Combines two materials (e.g., soft-touch grips on tools).
3. Micro Vertical Molders
   • For tiny parts like hearing aid components.

Key Benefits

 Gravity-Assisted Loading – Simplifies insert placement.
 Space Efficiency – 30–50% smaller footprint than horizontal machines.
 Multi-Material Capability – Overmold TPE onto rigid substrates.

Applications

• Automotive – Gearshift knobs with embedded electronics.
• Consumer Electronics – USB connectors with metal pins.
• Medical – Silicone-overmolded surgical tools.

Operation Workflow

1. Insert Placement – Manual or robotic loading of metal/ceramic parts.
2. Molding – Plastic injected around inserts.
3. Ejection – Finished hybrid parts discharged via conveyor.

Innovations

• Robotic Integration – Automated insert loading for high-volume production.
• Quick-Change Molds – Reduce setup time to <15 minutes.
