Compression molding was first developed to manufacture composite parts for metal replacement applications, compression molding is typically used to make larger flat or moderately curved parts.
This style of seal is sometimes less expensive to manufacture with certain materials and molding technologies (compression molding, transfer molding, injection molding), especially in low volumes.
This combination has the good surface finish, dimensional stability, and mechanical properties obtained in compression molding and the high-automation capability and low cost of injection molding and transfer molding.
Polymeric dense membranes such as polytetrafluoroethylene and cellulose esters are usually fabricated by compression molding, solvent casting, and spraying of a polymer solution.
The process of compression molding forces the hot vinyl to fill the grooves in the stampers, and take the form of the finished record.
All common molding processes may be used, including injection molding, compression molding, and extrusion.
This process eliminates the steps required for die-cutting and compression molding, as it manufactures the foam and the product simultaneously.
Polyimide powder can be used to produce parts and shapes by sintering technologies (hot compression molding, direct forming, and isostatic pressing).
