Here’s a step-by-step overview of how aluminum pens are manufactured.

(1) Mold Design & Manufacturing

Process: Custom molds are created for the plastic components of the pen (e.g., caps, internal mechanisms). These molds are typically made from durable steel or aluminum using CNC machining or 3D printing.
Purpose: The molds ensure precise shapes for plastic parts during injection molding, where molten plastic is injected into the mold cavities.

(3) Automated Assembly Line

Process: Components (plastic parts, springs, ink cartridges) are assembled into the aluminum tube using robotic arms and conveyor systems. Machines press-fit parts, secure mechanisms, and ensure alignment.
Purpose: Automation ensures speed, consistency, and reduces human error.
