Design Rubber Grommets Suggestion
When designing custom molded rubber grommets, ensure cushioning, sealing, and protection for wires or tubing through sharp openings. Optimize groove size, diameters, and flange thickness for a secure, vibration-resistant fit. Choose materials resistant to heat, abrasion, moisture, and chemicals. Account for panel thickness, mounting method (snap-in or push-in), and tolerances to ensure a lasting, reliable seal.
