A: Traditional rubber strip joint processes (adhesive/cutting) have obvious defects: gaps cause water/dust leakage, low joint strength, and easy aging/falling off. Injection corner jointing uses secondary vulcanization fusion technology: put the cut rubber strip ends into a precision mold, inject the same raw rubber at high temperature/pressure, and fuse the joint with the main body through vulcanization. The joint strength reaches ≥90% of the main body, realizing seamless IP67-level sealing, and the aging resistance is completely consistent with the rubber strip—perfect for corner connection of automotive/special-shaped industrial sealing strips.
A: Ultra-low temperature rubber strips (cold storage, liquid nitrogen equipment, alpine automotive sealing) need to avoid hardening/cracking at low temperatures, and the recommended materials are:
Structurally, it is recommended to use a soft design (40-50 Shore A), appropriately reduce the cross-section thickness to avoid excessive low-temperature compression and ensure sealing performance.
A: Rubber strip sealing performance is tested according to IEC 60529 IP grade standard, simulating actual installation conditions for dustproof and waterproof tests:
A: NEV rubber sealing strips have three core special requirements based on battery and motor characteristics:
The main materials are still EPDM/HNBR, but the formula is optimized for high temperature/anti-static performance, and the structure is designed with double sealing for key parts (battery pack).
A: Rubber strips are prone to aging/cracking due to environmental factors, and simple daily maintenance can effectively extend their service life (3 key methods):
For outdoor rubber strips, it is recommended to add a protective cover in extreme weather (high temperature/snow) to reduce environmental erosion.
