Certain manufacturing applications require extreme flatness, reliable heat transfer, and consistent pressure performance during pressing to achieve the optimal final results. In many cases, using a standard off-the-shelf platen simply won’t suffice, and these projects require custom platens for 4-post hydraulic presses. At Venango Machine Company, we specialize in designing and manufacturing custom platens for a variety of applications, including laminate manufacturing, rubber molding, and production of carbon fiber and other composites. Our American-made platens are built to meet the toughest thermal and structural performance requirements in composite, rubber, and industrial molding processes.
From high-temperature composite curing to heavy-duty rubber molding, our custom platens for 4-post hydraulic presses are engineered and precision-machined to give manufacturers the accuracy, repeatability, and longevity their applications require.
Built for 4-Post Hydraulic Press Performance
A 4-post hydraulic press, or a 4-column hydraulic press, is widely used in applications that require uniform pressure and access to the workpiece from all sides. Characterized by the four independent vertical columns at each corner of the platen, the 4-post press delivers uniform pressures with precise control over force and the speed at which that force is applied. However, the true performance of the press depends on the quality and design of the platens. At Venango Machine, we deliver custom platen systems designed for both new press builds, like a custom hydraulic press manufactured by Custom Engineering, as well as retrofit projects for older presses. The strict quality control standards at Venango ensure all platens are manufactured to tight tolerances with reliable heat zones and complete process control. We work directly with OEMs, press manufacturers, and end users to deliver platen solutions that support high-volume, high-precision production.
What Sets Our Custom Platens Apart?
Venango Machine offers a comprehensive range of expert manufacturing capabilities for precision-ground, drilled, and internally-machined platen systems. With decades of experience, the team at Venango Machine is extremely capable of producing custom platens for 4-post hydraulic presses. The benefits of choosing Venango Machine include:
Start to Finish / Turnkey Solutions
The most common request for custom platen requires hands-on involvement and collaboration from start to finish. These turnkey solutions involve Venango Machine working closely with your engineers on the initial design through the final inspection process. Venango Machine provides full-service manufacturing of custom platen systems.
Uniform Flatness and Structural Integrity
Each platen is milled, stress-relieved, and surface-ground with exacting precision to tight tolerance specifications, ensuring even pressure distribution, thermal radiance, and uniform contact with materials. Venango Machine is capable of meeting the strictest requirements for parallelism and flatness across large-format platen surfaces, using Blanchard and other surface grinding techniques.
- Surface grinding capacity: Up to 120″ x 40″
- Flatness tolerances down to ±0.001″
- Stress-relieving heat treatment to prevent warping under load
Electric, Steam, and Fluid-Heated Platens
Venango Machine designs and builds custom heated platens capable of operating at temperatures exceeding 1200°F using several different heating methods, depending on the end applications. Each platen heating method would have unique maximum temperatures and cool-down times, and these are carefully selected based on the materials used during pressing. We deliver complete thermal systems designed for consistent and uniform heat transfer, tailored to your process needs.
- Steam-heated platens are typically best suited for rubber compression molding
- Electric cartridge or strip heater platens for precise zone control on high-temperature applications
- Oil or water heating channels for improved thermal cycling that improve throughput
Customizable Platens & MultiZone Control Panels
Our in-house engineering team collaborates with each customer to ensure every platen integrates seamlessly with their press and tooling setup. Every platen we produce is built to the customer’s exact dimensions and specifications, and in some instances, those design requirements demand a platen that can achieve multiple different temperatures along a singular surface. To achieve this, platens are outfitted with a MultiZone Control Panel, which delivers the precision control necessary to produce quality products with fast recovery times. These MultiZone systems are proven to reduce mold surface temperature variation by almost 400%!
Venango Machine Understands These Applications
Venango Machine Company is the world’s largest and oldest exclusive platen manufacturer, and over the last several decades has been a critical contributor to the nation’s industrial prowess and advancement. Whether you only require a simplistic platen to keep an old press operational or have more demanding specifications for custom platens, we have the experience and knowledge to build your custom hydraulic press platen. Platens from Venango Machine are widely used in:
Aerospace & Defense: Our high-temperature platen systems are used in the curing of composite structures and the forming of precision aerospace components that require extreme flatness and repeatability.
