Robotic Hands: The Ultimate Solution for 9g Ultra-Light Preform Ejection

Robotic Hands: The Ultimate Solution for 9g Ultra-Light Preform Ejection

---

When preform weight drops below 10g, traditional production methods hit their physical limit. For 9g ultra-light preforms, sticking and clamping become the number one enemy of productivity and yield. Why? Gravity becomes insufficient for reliable ejection, and surface tension causes delicate preforms to cling to the mold.

The Real Cost of Manual/Non-Robotic Production:

· Clamping rates typically range from 3-8% for 9g preforms.

· Each clamping incident causes 5-15 minutes of unplanned downtime and material waste.

· This translates to hundreds of lost production hours and significant annual cost.

Why Robotic Hands are the Definitive Answer:

A specialized sprue picker or robotic take-out system doesn't just remove the preform; it provides a programmed, consistent, and sensor-controlled ejection process. It solves the root cause by applying precise, multi-axis movement to gently but decisively detach the preform.

Key Advantages & ROI:

1. Eliminate Clamping: Reduce clamping rates to near-zero (often below 0.1%).

2. Maximize Uptime: Reclaim hundreds of productive machine hours annually.

3. Protect Quality: Prevent scratches and deformation caused by manual handling or unstable free-fall ejection.

4. Fast ROI: Most systems pay for themselves in less than 12-18 months through saved material, labor, and regained capacity.

For any producer serious about lightweighting and stable, high-yield production of 9g or lighter preforms, investing in robotic automation is not an extra cost—it's essential for maintaining a competitive edge.
