Hydraulic presses perform compression molding/Forming two materials with one stone

摘要

Many companies in the aerospace, automotive, sporting goods, and wind energy industry segments are using composites and thermoplastics to augment and support metal stampings. These nonmetallic materials also are used in industrial, electronics, oil and gas, and military applications. Historically, composites were more expensive than their steel and aluminum counterparts. Demand for composites resulted from light weight requirements or for use in demanding applications requiring high strength-to-weight ratios, corrosion resistance, and so forth. Composite materials can be glass, thermoplastic, phenolic, or epoxy. Lower composite costs and rising steel prices have driven additional demand for composites, and volatile fuel prices have created an increased need for lighter material for increased efficiency.
