The benefits of compression molding plastic parts:

• Suitable for advanced composites. Because there are no sprues, runners or gates like in injection molding,  compression molding shops are able to work with advanced composites that contain fillers and fiber reinforcements, and manufacture plastic parts that are often more durable, wear resistant and corrosion resistant than metal. 
• UHMW plastic parts cannot be injection molded; they must be compression molded or machined.
• Compression molded parts can be manufactured from a wide range of engineered plastics including UHMW, as well as other polymers such as rubber and silicone, and composites that are heavily loaded with fillers and fiber reinforcements.
• Parts compression molded from UHMW-PE are extremely wear resistant, impact resistant and corrosion resistant and can withstand extreme cold and high temperatures. Read more about UHMW benefits. 
• Compression molded parts are more durable, dimensionally stable, have a lower co-efficiency of friction, as well as enhanced dielectric properties.
• Little Waste - Compression molded plastic parts are manufactured to near net shape so very little material is wasted. The compression molding process is ideal for working with expensive compounds. Any leftover resin can be easily recycled.
• Compression molding allows for more intricacies in geometry. Compression molding shops are able to manufacture parts with holes or other features, often eliminating the need for secondary operations.
• Many traditionally metal parts are easy to convert into compression molded plastic parts because it is possible to match the part's geometry. As an example, snowmobile skis once made out of steel are now primarily manufactured by compression molding UHMW plastic.
• Compression molding can be used to manufacture large, bulky plastic parts that cannot be manufactured using other processes, and can manufacture parts from polymers that are not suitable for other processing techniques.
• Compression molding is an excellent choice for plastic parts that have a variable wall thickness.
• Compression molding is seamless and produces fewer knit lines on final products than other techniques.
• Lower Cost – The compression molding process is very cost-effective for manufacturing plastic products with a longer product lifespan compared to other plastic parts manufacturing techniques.  The process of compression molding plastic parts from resin is fairly simple compared to other processes such as injection molding, and production of molding tools is less expensive.
• Suitable for High Volume Production – Cycle times are longer than with injection molding, but products that have a long product lifespan can be compression molded more cost effectively. Compression molded parts are highly repeatable for mass production.
• Compression molding is, by far, the best way to process large, intricate plastic parts.
• Compression molded parts are extremely strong and durable and have excellent dimensional stability and machining accuracy.
