Our AI captures your project specifications for both the thermoplastic resin and the insert component, ensuring performance requirements like pull-out strength, conductivity, and tolerances are understood from the start.
Plastic and insert material specification
The AI analyzes your CAD model to optimize plastic flow around the insert, preventing voids or damage. It also provides feedback on insert design features like knurling and undercuts to maximize anchoring strength.
Automated DFM for insert encapsulation and anchoring
Our AI designs robust tooling with precise features (pins, magnets, or custom shutoffs) to securely hold the insert during high-pressure injection. It also determines the optimal loading strategy, from manual placement to high-speed robotic automation.
Intelligent mold design and insert loading strategy (manual vs. robotic)
Track the molding operation in real-time, with AI-powered updates on insert placement accuracy, injection pressure, and melt temperature to prevent insert shifting or damage.
Live monitoring of insert position and process parameters
Stay informed with automated follow-ups and detailed reports on material lot traceability, process validation, and dimensional inspection, including verification of insert position and integrity.
Comprehensive FAI with insert positional and functional validation
The AI proactively identifies insert molding risks like insert shifting, flash onto the insert, or incomplete encapsulation, and implements compensating process strategies before defects occur.
Predictive insert shift control and melt flow optimization
AI coordinates CMM inspection and automated visual inspection to ensure every part meets dimensional specs and that the insert is correctly positioned, clean, and fully functional.
Automated dimensional validation and insert integrity checks
From part ejection and inspection to custom packaging and delivery, the AI optimizes the entire post-molding workflow for speed and cost-efficiency.

Why Choose Our
AI Platform
24/7 Production Capability
Our AI never sleeps, managing your injection molding projects across multiple presses and materials for continuous production.
Eliminate Secondary Assembly
Integrate metal components directly into your plastic parts, eliminating costly and time-consuming post-molding steps like heat staking, ultrasonic welding, or manual assembly.
Unmatched Part Reliability
By physically encapsulating inserts in plastic, we create an exceptionally strong mechanical bond that resists loosening from vibration, shock, or repeated use.
Enhanced Component Design
Our process allows for the creation of complex, consolidated parts that combine the strength and conductivity of metal with the lightweight and design freedom of plastic.
Precision & Repeatability
AI-controlled insert placement and process management ensure every insert is perfectly positioned and encapsulated, delivering superior consistency across high-volume production runs.

Frequently Asked Questions
How does AI improve the insert molding process?
Our AI is crucial for ensuring precise and repeatable insert placement via robotics. It optimizes melt flow to prevent insert damage or shifting during injection and uses computer vision to verify correct placement and inspect the final encapsulated part.
What is the difference between insert molding and overmolding?
Insert molding involves molding plastic around a non-plastic item (usually metal). Overmolding is the process of molding plastic over another plastic part.
How do you prevent the insert from moving during molding?
Our AI-assisted mold design incorporates precision features like pins, sleeves, or magnets that securely hold the insert in place. We also control the injection speed and pressure to create a gentle, even flow of plastic around the insert.
How does insert molding save money?
The primary cost saving comes from eliminating secondary assembly. Instead of paying for labor and equipment to press, glue, or weld inserts after molding, the process is consolidated into a single, automated step.
What design features improve an insert's strength?
To ensure the insert is permanently locked in the plastic, features like knurling (a rough, diamond-shaped pattern), grooves, undercuts, and holes can be designed into the insert to give the plastic more surface area and geometry to grip onto.
