The Impact Resistant Impact of Compression Molding

Part design and analysis has been something of a "black art" since the inception of compression molding many years ago, where experience, manufacturing processes, and many trade secrets have been developed and perfected overtime to make the creation of molded parts an extremely popular, efficient, and effective way of manufacturing a variety of plastic products.

The basic notion of molding was employed in the baking business to manufacture cookies and cakes before advanced plastics ever existed to be molded. However, since 1907, when Leo Baekeland used a crude compression machine, formaldehyde resin, and steam to manufacture the first plastic mold, compression molding has continued to grow and expand to become a critical manufacturing process.

Advantages of Compression Molding

The technique's advantages are apparent, and they greatly outweigh its few drawbacks. Manufacturing processes are still utilized today in industries all over the world for parts, components, and full products, for a variety of reasons.


Fast set up a time

Low initial setup costs

Capable of large size parts beyond what's possible with most extrusion techniques

Allows the molding of large and small intricate parts

Capable of good surface finish

Wastes little material

Can take advantage of thermoplastics with unidirectional tapes, woven fabrics, fiber mats, and more.

This method of molding results in fewer knit lines and less fiber-length degradation than other processes, like injection molding.
