The Advantages of Compression, Injection, and

2014-10-20 · Compression Molding. The advantages of compression molding are three-fold: Low cost Due to its simplicity, compression molding is very cost-effective when compared to other techniques.. Little waste Little material is lost during the molding process. For example, it does not use gates, sprues or runners, tooling features required by other production methods that

The Difference Between Extrusion and Injection

2020-2-12 · Plastic manufacturers primarily use two methods for plastic molding. In the first, plastic injection molding, manufacturers inject molten plastic resin into a mold and let it settle and cool into a specific shape. In the second, plastic extrusion, manufacturers push melted plastic through a die to create the desired shape. Each method has unique advantages []
