Post-Molding Automation for Injection Molding
1. Introduction
Post-molding automation plays a critical role in improving efficiency, consistency, and cost-effectiveness in injection molding production. Once a plastic part is molded, various automated systems take over to handle part removal, trimming, inspection, sorting, and packaging. This page introduces the core post-molding automation solutions we provide for general-purpose injection molding applications.
2. Key Post-Molding Automation Solutions
2.1 Part Removal – Robot Arms
Automated robotic arms remove molded parts from the mold. These robots can be:
- Top-entry (vertical) robots – Common and reliable, suitable for most standard machines.
- Side-entry robots – Faster and better for high-speed or low-ceiling environments.
2.2 Conveying Systems
After removal, parts are placed onto conveyors for transfer to the next station (trimming, inspection, etc.).
2.3 Runner Trimming (Degating)
Automatic gate cutting systems remove excess material from parts, especially useful in multi-cavity mold setups.
2.4 Visual Inspection
Vision systems or sensors are used for basic defect detection, verifying part integrity before packaging.
2.5 Counting & Sorting
Counting systems group parts by quantity for batching or packaging, with optional sorting based on weight or dimensions.
2.6 Automatic Packaging
Automatic bagging, sealing, or boxing equipment helps reduce manual labor and improve packaging speed and consistency.
