01Symptom02Cause03Material & process04Verification
Choose the symptom closest to your project below. We then connect it to a cause, a manufacturable route and a verification method.
01 / PROBLEM DIAGNOSIS
What you see is only the symptom.
Open each route to see how the problem becomes a manufacturable, verifiable part.
01WHAT THE CUSTOMER SEESLeakage around corners, joints or screw positions
+
Leakage around corners, joints or screw positions
LIKELY CAUSE
The seal path is discontinuous or compression is uneven.
WANXIN ENGINEERING ROUTE
Map the full seal path and convert closed-cell foam or elastomer with controlled joints.
HOW TO VERIFY
Send this problem to engineeringCompression, recovery, fit and customer product-level water / dust test.
02WHAT THE CUSTOMER SEESFoam creeps, stretches or is difficult to place
+
Foam creeps, stretches or is difficult to place
LIKELY CAUSE
Material firmness, adhesive and liner presentation do not match assembly.
WANXIN ENGINEERING ROUTE
Review foam grade, compression ratio, adhesive surface and liner split.
HOW TO VERIFY
Send this problem to engineeringDimensions, density / thickness, compression set and placement trial.
02 / BUILD THE SOLUTION
Material, process and proof must work together.
Converting route
Through-cut waterproof gaskets and pads
Adhesive lamination and easy-peel liner
Joined or continuous seal paths
Nested layouts for material use
What to verify
Gap and compression ratio
Recovery and repeated loading
Seal path, joints and screw pressure
Water, dust and temperature exposure
