Plastic Injection Engineer


Plastic Injection Engineer (IME) enables the validation and optimization of plastic parts and mold tooling designs by simulating the filling, packing, warpage & mold cooling early in the product development process.

Plastic Injection Engineer brings easy-to-use injection molding simulation directly to the designers of plastic parts and injection molds. It simulates how melted plastic flows during the injection molding process to predict manufacturing-related defects on plastic parts. You can quickly evaluate manufacturability while you design, to eliminate costly part redesign, improve part quality, and accelerate time to market. Plastic part designers and product developers can analyze and modify designs at the same time as optimizing for form, fit, and function. Mold tool designers can evaluate and optimize the feed system and cooling circuit designs.

Minimal simulation knowledge is needed and workflows are made easy through a guided simulation assistant. Single-cavity, multi-cavity, and family mold layouts, including sprues, runners, and gates can be analyzed to obtain estimated cycle time, clamp tonnage, and shot size, enabling you to optimize the feed system design and avoid costly mold rework. Both hot-, and cold-runner systems can be analyzed and so can valve gates. Users can analyze simple or complex mold cooling line layouts including mold cooling inserts, optimize cooling system design to minimize cycle times and decrease manufacturing costs and optimize part and mold design, material selection, and processing parameters.

Plastic Injection Engineer also supports simulation of advanced molding processes including, Insert Overmolding, Two-shot Injection, Multi-shot Injection, Powder Metal Injection Molding.

Plastic Injection Engineer benefits from Simulation Data Science capabilities enabling all simulation activities, models, and results to be linked, traced, updated, re-used, and analyzed with ease by all impacted users.
