Rubber Compression Molding
Rubber molding creates rubber parts by pressing a heated block of rubber into a metal cavity.

Aluminum is a popular choice for many metal products and components:
Rubber Compression Molding Parts
One of the most popular aluminum alloys used in sheet metal fabrication. It is readily bent, punched and sheared.
Known for its high corrosion resistance, especially in ocean water. Common applications include marine and aircraft equipment, fuel lines, street lights, household appliances, flooring panels, and railings.
Used in applications requiring high strength to weight ratio, and has good fatigue resistance. It is not weldable and has average machinability.
Corrosion resistance is poor. Widely used in aircraft structures, especially wing and fuselage structures under tension.
Has generally good mechanical properties, and is heat treatable. Highly weldable although strength near welds can be diminished by up to 30% if not subsequently heat treated.
Mostly used in extruded shapes for architecture, including window frames, door frames, roofs, piping, tubing and furniture.
Strong, with good fatigue strength and average machinability, but is not weldable and has limited resistance to corrosion.
Cost is relatively high compared to other Aluminum alloys. Often used in aircraft including wings and fuselages, rock climbing equipment and bicycle components.
