For any extrusion die manufacturer, good die design is a major factor in ensuring extrusion dies will always produce a quality final product. Balanced melt flow across the die ensures uniform exit velocity and output consistency. Expert die design achieves this uniformity in a continuous fashion with minimal pressure drop.
Die design also affects productivity since it impacts on the throughput of the extruder. These parameters directly relate to extruder back pressure and, in turn, product density and screw efficiency. Critical factors include:
All dies are manufactured using a smart, modular design to allow rapid fitting and removal. The special Diamond America swing bolt configuration means that changeover between runs, or disassembly for cleaning or maintenance takes only minutes.
Diamond America engineers test the material to be extruded to ensure correct die design for its specific properties and rheology using computer flow analysis. They also assess and consider the client’s process, production and yield requirements. This thorough approach provides the critical information Diamond America needs to create and build a custom die, whether monolayer or multilayer, that will fulfill all material requirements and ensure a consistently excellent extruded product.
Whether it’s Flow Control Dies, Forming Extrusion Dies or Sheet and Film Dies, all Diamond America extrusion dies are backed by intimate knowledge of extrusion equipment and optimized for overall equipment efficiency.
Diamond America offers custom designed extrusion dies for any application. Besides using only the highest grade materials and best die tooling, the latest developments in metallurgy, heat treatment and coatings are employed to guarantee the best results.
