PROJECT TITLE:

7 Layer Die for blown film

PROJECT DESCRIPTION:

Magna machined and assembled what we understand is currently the largest 7 layer blown film die in the world for one of the major OEM’s in the plastics industries. The job was a build to print project that required larger machining faculties than our customer had in house. We could manage this project ahead of the schedule needed by our customer because of the large numbers of machines we have in house to perform the work and our years of experience machining die parts.

The client chose us based on our experience in machining these large parts.

Difficulties Overcome: The handling of this size highly polished parts is extremely difficult to avoid damage.

Positive Client Feedback: We received a letter of gratitude after the project was completed.

Special Feature of this Product: There are mutable layers of large diameter parts with very close tolerances that must stack up, and are then checked for concentricity after assembled that make it impossible for the average machine shop to do.

Finished Product:

CNC Machinist
Polishers and Assemblers
