What are common failure modes of Gasket?

Common issues with Gasket and troubleshooting methods:

Issue 1: Substandard Performance** - Possible causes: Raw material batch variation, formulation ratio deviation, inadequate mixing, inappropriate cure conditions - Investigation: Review raw material inspection records, verify formulation weighing data, test Mooney viscosity and cure characteristics of mixed compound, confirm cure temperature/time/pressure within process range - Solution: Strengthen incoming raw material inspection, standardize batching and mixing operations, optimize cure process parameters

Issue 2: Premature Failure / Insufficient Service Life** - Possible causes: Inappropriate material selection (does not meet actual service conditions), design defects (stress concentration, unreasonable structure), service environment exceeding expected range, improper installation - Investigation: Analyze property changes of failed samples (hardness, strength, elongation), review installation records and service environment data, conduct failure mode analysis - Solution: Re-evaluate material selection rationale, optimize product design, strengthen installation training and quality control

Issue 3: Appearance Defects (bubbles, cracks, surface irregularities)** - Possible causes: Excessive moisture content in raw materials, improper mixing temperature control, inadequate venting during cure, mold design or maintenance issues - Investigation: Test raw material moisture content, review mixing process records, observe venting during cure, inspect mold condition - Solution: Strengthen raw material drying, optimize mixing process, improve mold venting design, perform regular mold maintenance

Issue 4: Poor Batch-to-Batch Consistency** - Possible causes: Unstable raw material sources, process parameter fluctuations, operator variability, environmental temperature/humidity changes - Investigation: Statistically analyze key performance data across batches, trace raw material batch sources, review process parameter records - Solution: Stabilize raw material supply chain, establish strict process control standards, strengthen in-process inspection and Statistical Process Control (SPC)
