Compression Molding Press25/3/2022
Compression Molding Press A compression molding press is the most widely used production method for rubber molding. It is ideal for low to medium volumes and can be used for a largest variety of part sizes and materials, including high cost materials, and applications that demand extreme hardness. It is a very useful molding process for forming bulky parts, gaskets, seals and O-rings. It is also a very efficient, low waste method that offers the simplest process, lowest investment, and greatest flexibility. Compression molding generally results in lower amounts of scrap. It does not consume excess rubber in the runner of an injection mold, or in the pot of a transfer mold.Get more news about compression moulding machine,you can vist our website! French supplies a wide variety of custom and standard compression molding press designs generally from 20 tons to 2,000 tons for a wide variety of molding applications and materials ranging from thermoset to thermoplastics, including laminates, composites and more. Contact French engineers for additional questions or download literature our hydraulic presses for more information.The most commonly viewed drawbacks to compression molding are longer cycle times and costly labor costs. However, both of these can be addressed to equal or surpass the injection molding process. Cycle times for compression molded parts using preheated preforms can be less than for injection molded parts. Automated preform, loading/unloading, and post handling equipment can be integrated with a compression press to nearly equal the labor cost of injection. High Durometer Materials – Medium hardness materials (60A-90A) work the best in compression molding. Compression molding is easily capable of molding material of even higher durometers. Higher cavity pressure can be difficult to obtain with other molding processes without degradation of material properties. Filled Materials -The compression molding process is well suited for molding materials that are combined with stiffening fillers. Fiber orientations are not altered of destroyed as commonly observed in injection molding. Virtually all thermoset materials, from bulky material compounds to very high durometer materials Mostly every molding industry from industrial to aerospace
