Seal Rounded Corners by Starting with These Three Measurements

Seal Rounded Corners with Bulb Trim Seals Do you need to seal rounded corners against wind, water, dust, or dirt? Bulb trim seals are industrial rubber products that provide sealing and insulation for machine doors, vehicle hatches, and equipment enclosures. They’re designed to seal rounded corners and have separate bulb and retainer sections. Each of these sections can use a different material and have a different durometer or hardness.

With bulb trim, the bulb section compresses to form a seal when the door, hatch, or enclosure is closed. The trim or retainer section attaches to a flange or substrate. To choose bulb trim for your application, you need to specify the bulb size, bend radius, and flange thickness. By choosing the right bulb size, you can avoid over-compression. The right bend radius and flange thickness help to avoid kinking and leakage. (more…)

Sound Absorbers for Noise Control

Sound AbsorbersSound absorbers are custom acoustic insulation that absorbs sounds instead of blocking or damping them. They’re made of foams and facings and used at the source of the sound and at its receiver. To choose the right noise control solution, engineers need to understand how sound absorbers work, which types are available, what questions to ask during material selection, and how sound absorbers are made. (more…)
