01
Medical Devices:
Found in precision fluid pumps, surgical tools, and portable drug delivery systems where absolute reliability and compact size are required.
02
Automotive:
Used in power window actuators, side-mirror folding motors, HVAC damper controls, and electric vehicle battery cooling pumps.
03
Aerospace & Defense:
Integrated into unmanned aerial vehicles (UAVs/drones), missile guidance fins, and satellite components.
04
Robotics & Automation:
Used in micro-servo motors for articulated joints and optical sensors.
05
Micro Drawing: Also known as stretching, is a process that shapes a metal sheet into a three-dimensional shape.
Micro Blanking: The cutting process to shear the metal sheet in one press stroke.
Micro Necking: Used to reduce the diameter of a section in a tubular feature of a micro part.
Micro Punching: The process of creating small holes or indentations.
Micro Slotting: Used to create precise micro slots.
Micro Bending: Amanufacturing process that produces a V-shape, U-shape, Z-shape, etc.
Micro Notching: Used to create precise notches on micro parts.
Micro Deep drawing: Aprocess that forms a deep, three-dimensional shape from a metal sheet.
Micro Lancing: Used to create precise tabs or flanges on a miniature component.
Micro Chamfering: Used to create beveled edges.
Micro Slitting: Used to create precise slits.
Micro Coining: Used to create precise, three-dimensional shapes with different height levels on micro parts surface.
Micro Swaging: Used to generate a V-shaped feature in a tubular section, generally after micro drawing or micro deep drawing process.
