All About Compression Molding

Please Share

Since the birth of compression molding many years ago, part design and analysis has been somewhat of a "black art" where experience, manufacturing processes and many trade secrets have been developed and perfected over the years to eventually make the creation of molded parts an extremely popular, efficient, and effective way of manufacturing a number of plastic products.  You can also get the best service of compression molding presses from various online sources.

Interestingly, before advanced plastics even existed to be molded, the basic concept of molding was used in the baking industry to create cookies and cakes. However, since 1907 when Leo Baekeland created the first plastic mold by using a primitive compression machine, formaldehyde resin, and steam, compression molding has continued to develop and expand upon itself to become the vital manufacturing process it is today.

The benefits of the technique are undeniable, and they far outweigh its few downfalls. For many reasons, the manufacturing techniques continues to be used today in industries everywhere, for parts, components, and entire products that are large and small.

Advantages

  • Fast set up time
  • Low initial setup costs
  • Capable of large size parts beyond what's possible with most extrusion techniques
  • Allows the molding of large an small intricate parts
  • Capable of good surface finish
  • Wastes little material

Can take advantage of thermoplastics with unidirectional tapes, woven fabrics, fiber mat, and more. This method of molding results in fewer knit lines and less fiber-length degradation than other processes, like injection molding.
