Wire Electrical Discharge Machining

BlissPak is equipped with a GF AgieCharmilles CUT 20P Wire EDM, a high-performance CNC wire electrical discharge machining system designed for ultra-precision mold and component manufacturing.

In thermoforming and blister mold production, the CUT 20P plays a critical role in machining high-accuracy mold components that require tight tolerances and complex geometries, especially where conventional CNC milling reaches its limits.

Key applications in thermoforming mold manufacturing include:

• Precision cutting of forming mold inserts and core components
• Machining of trim mold cutting profiles and sharp contours
• High-accuracy processing of stacking mold features and alignment slots
• Production of complex internal geometries with excellent edge quality
• Ensuring dimensional accuracy and consistency for repeatable mold assembly

Thanks to its stable machining performance and excellent surface finish, the CUT 20P enables us to achieve high positional accuracy, sharp detail definition, and reliable part-to-part consistency, which are essential for thermoforming molds used in mass production.

This advanced Wire EDM capability significantly improves mold accuracy, reduces manual fitting, and contributes to longer mold life and stable forming performance in applications such as medical packaging, consumer goods, electronics, and industrial thermoforming.
