Since 1954 Venango Machine Company has been at the forefront of developing new technology critical for subsequent advancements in the rubber, laminate, composite, and plywood industries. One of the manufacturing practices omnipresent throughout these industries is reliant on heated compression molding presses to manufacture a wide assortment of essential products. Compression molding is used extensively to create products like rubber o-rings, gaskets, carbon fiber components, plywood, engineered wood, and even laminate plank flooring. This blog will provide a more in-depth understanding of compression molding, how electric platens are involved, and the benefits associated with choosing Venango Machine to fabricate these products for your company.

What are Heated Compression Molding Presses?

In simple terms, a compression press, or compression molding machine, is a hydraulically powered press that can be used to mold a wide array of materials into specific shapes or designs depending on the end application. Heated compression molding presses simply introduce heat to the molding process when necessary, most commonly with the aid of electric platens. Materials like rubber, carbon fiber, composites, laminates, and plywood all depend on the heat introduced through electric platens to help prepare, shape, and cure the material into the desired shape. In many cases, the material must also be cooled while compressed to attain the desired structural integrity necessary for the end component. Venango Machine electric platens are desired to not only reach the high temperatures required by heated compression molding presses but also cool quickly for specific applications.

Electric Platens & Heated Compression Molding Presses

The ideal platens for heated compression molding presses are electrically heated. These platens provide compression molders with a heating method with expedited heat-up and recovery times and the ability to achieve higher temperatures during operation. Considering compression molding is used for a variety of applications, temperature flexibility is essential to meet specific requirements. Venango Machine Company has developed several standard variations of the electric platen and each can be used in heated compression molding presses to achieve desired results.

  • Type SE – Strip Electric Platen: The strip electric platen uses a strip-type heating element to achieve desired temperature levels and is ideal for lower temperature or non-vacuum heated compression molding presses.
  • Type CE – Cartridge Electric Platen: These platens rely on round cartridge heaters to achieve the desired temperatures for heated compression molding presses especially high-temperature applications. Venango Machine has also developed a split electric platen to help customers remove and replace expired heating elements after burnout.
  • Type HT – Heat Tube Platen: The design of these platens incorporates a multi-layer lattice type structure of cartridge heaters and heat tubes. These can be a cost-effective retrofit option for heated compression molding presses and can be quickly integrated into existing equipment.
  • Type EWC – Electrically Heated & Water Cooled Platen: These specific platens are desired for applications that require both vacuum and non-vacuum procedures. Venango Machine offers specialty designs for heated compression molding presses that require severe heating or cooling temperatures.
  • Multi-Zone Electric Platen: Multi-zone electric platens are Ideal for applications that require precise temperature control across the platen face like carbon fiber manufacturing. The precisely controlled temperature levels ensure a quality product and faster recovery times that save our customers both time and money.
