Here’s a step-by-step overview of how aluminum pens are manufactured.
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.
Process: Long aluminum tubes are cut into smaller, pen-sized sections using automated cutting machines.
Purpose: This step customizes the aluminum body for functionality and aesthetics.
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.
Process: Workers visually inspect pens for defects (scratches, misalignment) and test functionality (smooth retraction, ink flow). Defective units are removed.
Purpose: Human oversight guarantees final product reliability and meets quality standards.
Process: Approved pens are packaged into boxes.They will be labeled later,and prepared for shipping.
Purpose: Ensures safe delivery to retailers or customers.
