Beryllium Bronze Mold Core Insert with HRC58 Hardness +/-0.004mm Accuracy and Customized Dimensions

Non Standard C17200 Beryllium Bronze Mold Core Insert Components For Home Appliance Plastic Parts

The Mold Core Inserts can be used for reaction and injection molding as well as for hot embossing. They can easily withstand temperatures up to 150°C and pressures of up to 10 MPa. Even after thousands of molding cycles, the microstructures do not show obvious wear or degradation.

Nevertheless, the replication of LIGA microstructures provides some specific challenges that are related especially to the high aspect ratio of the structures. First, the complete filling of the Mold Core Insert with the polymer is a critical process. To fill even the smallest structure details in the depth of the mold, which could be in dimension of submicrometers, the polymer must have a high filling ability, which means a low viscosity.

Also during the cooling phase, lunkers and cavities can be formed, which cannot be compensated for later on. Even more difficult is the demolding procedure. On mold release, any tilt of the Mold Core Insert must be avoided, i.e., the mold release should be carried out extremely parallel so that the microstructure will not be deformed or damaged. Finally, measures must be taken to avoid or counteract volume changes due to the shrinkage of the plastic on hardening with process control.
