Method Of Laser Marking One Or More Colors On Plastic Substrates
US Patent:
6284184, Sep 4, 2001
Filed:
Aug 27, 1999
Appl. No.:
9/384866
Inventors:
Jae Hong Choi - Carmel IN
Ronald Dale Hernandez - Shreveport LA
Ronald Dale Hernandez - Shreveport LA
Assignee:
Avaya Technology Corp - Basking Ridge NJ
International Classification:
B29C 4516
US Classification:
264400
Abstract:
A method for laser marking one or more colors on a plastic substrate is disclosed. A polymeric blend or mixture comprising two or more polymeric systems is utilized to produce a molded component. The various polymeric systems are heated to form a polymeric blend or mixture that is in a molten flowable state. The polymeric mixture is then shaped into the desired end product, preferably by injection molding. While molding, the polymeric mixture separates according to the different densities of the polymers; with the lightest density polymers migrating toward the inner surface of the mold and the heavier density polymers centralizing within the interior of the mold. The lightest density polymer forms the outer surface of the molded product, which may essentially constitute an outer layer coating disposed around the other polymeric systems. Upon removal of the cured layered product, the skin layer is then preferably ablated using a laser to expose the polymers of desired color beneath the outer layer. Other layers within the molded product may be ablated.

Assignee:
Avaya Inc. - Basking Ridge NJ
International Classification:
H04M 1/00
US Classification:
379447, 335303, 156 731, 264248
Abstract:
One or more method(s), system(s), and/or device(s) produces an assembly for securing a product to a dissimilar material, such as a magnet to plastic. A magnet assembly may include a plastic cap having one or more wings extending laterally from a side surface of the plastic cap. A plastic holder defines a product cavity and has one or more grooves formed to integrally fit with the one or more wings of the plastic cap. A magnet is positioned within the product cavity. The plastic cap is joined to the plastic holder, such as through staking or welding, to capture the magnet within the product cavity.
