A Look at How Compression Molding Is Used To Make Car Parts

July 18, 2014
Most likely, you have never really considered where car parts come from. You simply head to an auto body shop and before you know it, you have what you are looking for. Many car parts are made using a hydraulic press, just like those available at Press Master. Founded over 40 years ago, Press Master has developed a reputation as a premier hydraulic press manufacturer thanks to their wide variety of high quality hydraulic presses to choose from. Let’s look at the various car parts that are made from a compression molding, as well as the many advantages that compression molding offers.
What is Compression Molding?
​Compression molding is simply the act of utilizing heat and compression (force) to shape a raw material, such as metal alloy, plastic compounds, and rubber, using a formed mold. The process of using compression molding to make car parts starts with the material being fitted into the mold. Using a hydraulic press, the product is heated until it has become more pliable and soft. This process is not as easy as it sounds. It requires a carefully developed plan regarding the amount of force, material, and heat to be used, as well as close monitoring to make certain the part attains the appropriate shape and geometry. When the mold is opened the parts are ready for the finishing process. This includes painting, bonding, flashing (removal of excessive materials), and installation of inserts for fasteners.
Which Car Parts are Made From Compression Molding?
​Compression molding hydraulic presses are used to manufacture a wide variety of interior, application, and trim cover parts. For example, airbags, sun visors, head liners, air bags, gear stick knobs, sear covers, seat mesh insulation, carpet, and more. Metal alloys are often used for car hoods and fenders.
Main Advantages of Compression Molding
​One of the biggest benefits of using compression molding involves how cost effective it is. Moldings are low cost and labor is typically not as expensive as other options. In addition, there is minimal shrinkage during the molding process, especially when using rubber, as well as very little material wasted. Wasted materials that have overflowed the mold can be recycled by reheating them and adding them back, which reduces resource costs. This gives manufacturers the opportunity to use a more expensive compound to produce a higher quality product.
​Using compression molding also allows for a wider variety of part sizes and design changes can be easily made. Finally, molding ensures that you can produce consistent top-of-the-line car parts at fast production rates.
