Cryogenic deburring services

Part imperfections are one of the common reasons for product recalls and their failure. These imperfections may be caused due to several reasons ranging from material quality to the choice of wrong material or machining technique or excess material in some areas. Among various imperfections, burrs are a common concern for most plastic part fabricators across the world. The burrs are created if excess material is left behind during the machining process. These burrs add to the roughness of the surface and also alters its aesthetical appeal.

  3. INTRODUCTION CRYOGENIC DEBURRING IS A PROCESS WHEREIN DEBURRING IS PERFORMED AT EXTREMELY LOW TEMPERATURES OR CRYOGENIC TEMPERATURES. THE PART WITH A BURRED SURFACE IS PLACED IN A CRYOGENIC DEBURRING MACHINE AND IS COOLED TO EXTREMELY LOW TEMPERATURES UP TO -60 DEGREES FAHRENHEIT OR TO THE EXTENT THAT THEY BECOME BRITTLE. THE FROZEN BURRS ARE SUBJECTED TO .080 POLYCARBONATE MEDIA, WHICH REMOVES THEM WITHOUT ALTERING THE INTEGRITY OR AESTHETIC APPEAL OF THE PART.

  4. 1 MANUAL DEBURRING USING TOOLS SUCH AS FILES OR ABRASIVE PADS. COMMON METHODS 2 MECHANICAL DEBURRING • MECHANICAL TOOLS, LIKE BRUSHES, • GRINDING WHEELS, OR TUMBLING MEDIA 3 THERMAL DEBURRING CAUSED BY THE IGNITION OF A FLAMMABLE GAS TO REMOVE BURRS CHEMICAL DEBURRING 4 • SELECTIVELY DISSOLVE OR ETCH BURRS

  5. HOW CRYOGENIC DEBURRING WORKS ? • 1 .Workpiece Preparation: 4. Brittle Fracture of Burrs: The extreme cold makes the burrs brittle, and mechanical agitation within the chamber aids in breaking off these brittle burrs from the workpieces. 5. Post-Process Steps: After deburring, the temperature is gradually increased to avoid thermal shock, and any remaining debris is removed. The components undergo inspection to ensure the effective removal of burrs and meet quality standards. Components with burrs or sharp edges are readied for cryogenic deburring. 2. Cryogenic Chamber Loading: The prepared workpieces are placed inside a cryogenic chamber designed to withstand extremely low temperatures. 3. Introduction of Cryogenic Gases: cryogenic gases are introduced into the chamber, rapidly lowering temp of work piece

  6. 1 CRYOGENIC DEBURRING MAINTAINS THE ORIGINAL GEOMETRY AND SURFACE FINISH OF THE PART, ENSURING NO ALTERATIONS TO ITS SHAPE OR APPEARANCE. BENEFITS 2 • CRYOGENIC DEBURRING DOES NOT ALTER THE EDGES OF THE PART OR REMOVE MATERIAL, MAINTAINING THE INTEGRITY OF THE ORIGINAL DESIGN. 3 • THE PROCESS PRODUCES NO DUST OR RESIDUES AND IS HIGHLY EFFECTIVE IN REMOVING FLAKES OR SHARP PIECES FROM THE PARTS BEING DEBURRED.

  7. SAFETY MEASURES & GUIDELINES • PERSONAL PROTECTIVE EQUIPMENT (PPE): • INSIST ON INSULATED GLOVES, FACE SHIELDS, AND GOGGLES TO PROTECT AGAINST EXTREME COLD AND SPLASHES. • TRAINING AND CERTIFICATION: • CERTIFY OPERATORS IN SAFE EQUIPMENT USE, EMERGENCY PROCEDURES, AND CRYOGENIC GAS HANDLING. • VENTILATION AND ENCLOSURE: • IMPLEMENT EFFECTIVE SYSTEMS TO CONTROL CRYOGENIC GAS RELEASE AND ENSURE A SAFE WORKSPACE. • EMERGENCY RESPONSE PLAN: • CLEARLY OUTLINE PROTOCOLS FOR SPILLS, GAS LEAKS, AND EQUIPMENT MALFUNCTIONS • MATERIAL COMPATIBILITY ASSESSMENT: • ASSESS MATERIALS FOR COMPATIBILITY WITH CRYOGENIC TEMP TO PREVENT HAZARD
