Q

COC Laser Welding Failure

A

COC laser welding is a precise coupling of material matching and process parameters; batch light transmittance consistency is the basis of stable production; online inspection prevents batch failure.

Material Analysis COC; laser welding; light transmittance; welding strength; pores; matching

Q

COC Cold Resistance Impact Failure

A

COC low-temperature brittleness is a boundary condition that must be evaluated in material selection; cold chain applications require special verification; room-temperature data cannot be extrapolated to low-temperature conditions.; After confirming effectiveness, fix the parameters and practices...

Q

COC Insufficient Verification for Glass Replacement

A

COC replacing glass is a dual verification project of regulation and performance; the 18~24 month re-certification cycle must be included in the project plan; data package completeness determines the success or failure of replacement.

Material Analysis COC; glass replacement; pharmaceutical packaging material; verification; regulation; migration

Q

COC Excessive Back Pressure Degradation

A

COC back pressure 150 bar is the red line drawn by the supplier; mixing demand cannot be solved by exceeding back pressure; the damage of shear heat to high-viscosity materials is often underestimated.

Material Analysis COC; back pressure; shear heat; degradation; 150bar; mixing

Q

COC Brittle Fracture

A

COC brittleness is an inherent material characteristic, design and material selection are the main countermeasures; impact-modified grades can improve to above 100J/m; mechanical conditions must be re-evaluated when replacing PC.

Material Analysis COC; brittleness; impact; notch; modification; fracture

Q

ASA Weather Resistance Test Verification

A

ASA weather resistance looks at Delta E<3 four indicators, claims are inferior to verification; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
