Molding & In-line assembly Automation for medical plastic components

 

High Speed Automation The design principles of high speed automation are as follows: Long time tests of critical components Double sensor system Modem for remote maintenance Key Concerns for Production System Installation in Clean Room How to avoid particle generation and how to make production systems easy to clean are the key concerns for production system installation in clean room. Specifics For Production In Clean Room Area (I) With respect to the required clean room level an automation needs specific equipment, especially to avoid the generation of particles and/or to keep particles away from the product before it is packed. For example: Electrical direct drive e.g. Linearmotor - no timing belt Robot drive below product level Enclosure of the robot axes Enclosure of the End of Arm Tooling Enclosure of conveyors etc. Specific design of the clean room depending on clean room Specifics For Production In Clean room Area (II) Consider to use: Abrasion resistant timing belts & gear wheels (if required) Abrasion resistant cable Abrasion resistant pneumatic hoses Pneumatic valves with collector for exhaust air Vacuum pumps with collector for exhaust air Abrasion resistant guiding rails Scope of Technologies from HEKUMA GmbH HEKUMA GmbH can provide automization for following products as well as the products required by the customer: Petri-Dishes Pipette Tips Wells Syringes Infusion Ports Contact Lenses Tablet Dispensers Inhalors Spray Heads Razors Liquid Soap and Detergent Dispensers Major Advantages Of HEKUMA GmbH Automation Systems Capable for clean rooms up to class 1000; Special robot design “Cleanroom”; High precision; High uptime; High Product Quality; 100% Quality Control
