Mold for forming plastic mold part, has structure portion comprising microstructures, which are arranged in such manner that three-dimensional mark structure is formed with safety feature of mold part

摘要

#CMT# #/CMT# The mold has a structure portion removably formed at a surface area, where the structure portion comprises multiple microstructures (212) formed by steel engraving or laser ablation, and the microstructures comprise depth of about 10 to 500 micrometer. The microstructures are arranged in such a manner that a three-dimensional mark structure (220) is formed with a safety feature (230) of a plastic mold part (200). The microstructures include complex line patterns such as random patterns. #CMT# : #/CMT# An independent claim is also included for a method for manufacturing a mold. #CMT#USE : #/CMT# Mold for forming a plastic mold part (claimed). #CMT#ADVANTAGE : #/CMT# The plastic mold parts can be produced in a simple and inexpensive manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a plastic mold part. 200 : Plastic mold part 212 : Microstructures 220 : Three-dimensional mark structure 230 : Safety feature.
