2025-04-14

Extrusion mold

The material of the extrusion mold should be rust - resistant; and the molding size of the rubber strip and the height of each airbag should comply with the drawings/samples.
The standard requirement for extrusion molds is that there should be no repairs to ensure smooth processing of the front cover,The screw cap shall not be larger than the insert.
Extrusion die diameter: φ90-0.3mm, Customized according to customer requirements. The extrusion die uses slow wire.

Shaped mold

The cooling mold assembly is complete, with rounded chamfers, complete cooling holes, and stainless steel water nozzles.
The cooling die is coded (consistent with the extrusion die), the sealing ring is leak proof, and the fixing bolts are made of stainless steel.

Testing mold

Qualified rubber strips should be fully filled and free of gaps or wrinkles when passing through the inspection mold, ensuring smooth threading and chamfering.
Detect the die with the strip, and chamfer the strip to encode (consistent) glossiness.

Mold testing requirements:

Use SJ75 extruder for testing to ensure compression ratio.

Shipping packaging:

The extrusion mold is fixed with a paper tube, and all molds are tightly packaged to prevent rain and moisture, ensuring that the goods are intact during violent transportation by express delivery.
