Cushioning / Waterproof Sealing

Define the seal path, closed-cell foam, compression ratio and assembly conditions together.

START WITH THE FAILURE MODE

Where can water, dust or vibration pass through the housing?

Define the seal path, closed-cell foam, compression ratio and assembly conditions together.

01 / PROBLEM DIAGNOSIS

What you see is only the symptom.

Open each route to see how the problem becomes a manufacturable, verifiable part.

01
WHAT THE CUSTOMER SEES

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

Compression, recovery, fit and customer product-level water / dust test.

Send this problem to engineering
02
WHAT THE CUSTOMER SEES

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

Dimensions, density / thickness, compression set and placement trial.

Send this problem to engineering
02 / BUILD THE SOLUTION

Material, process and proof must work together.

01

Candidate materials

EVA / PE closed-cell foam

PORON polyurethane foam

SEKISUI-type foam families

Silicone foam / rubber

02

Converting route

Through-cut waterproof gaskets and pads

Adhesive lamination and easy-peel liner

Joined or continuous seal paths

Nested layouts for material use

03

What to verify

Gap and compression ratio

Recovery and repeated loading

Seal path, joints and screw pressure

Water, dust and temperature exposure
