TL;DR – Article Highlights
- Custom-machined platens are industry-specific steel plates engineered and manufactured to provide optimal heating, cooling, and uniformity to an array of specialized applications.
- Look for a vendor, like Venango Machine, that sources appropriate platen materials and can provide the precision grinding and gundrilling services entirely in-house.
- Ideal partner for OEMs, press manufacturers, laminators, and industrial equipment builders needing reliable thermal platens. *Note: Venango Machine can save you time and valuable hours on your high-tolerance machining. Venango will supply the basic machining, leaving the high-tolerance pockets or cavity work to you, the mold maker.
From Material Supply to Gundrilling: What Sets Venango Apart
Custom-machined platens combine precision engineering, skilled machining, expert grinding, and tight-tolerance gundrilling with steel plates to create controlled heating and cooling cycles with optimal surface uniformity. Prized by plywood, lumber, rubber, composite, and other manufacturers, Venango Machine’s custom-machined platens are built to unique specifications and deliver impressive results.
Venango goes a step further than other platen manufacturing companies by sourcing the exact material specified in the project requirements on behalf of the customer. Rather than working with outside parties to source raw steel plate material, the experienced and knowledgeable team at Venango actively manages material procurement. This in-house process reduces customer workloads and guarantees material grades, certifications, and delivery timelines of standard steel plate and other alloys.
Unlike mold bases or high-tolerance pockets used in tool and die work, platens prioritize thermal management, flatness, and dimensional accuracy across large surfaces. These properties are essential for industrial manufacturing lines, laminating systems, composite processes, and OEM machinery and require an experienced gundrilling company to create these channels or holes in hard-to-machine steel plates.
Venango Machine specializes exclusively in platen-level manufacturing—not moldmaking—ensuring customers receive high-quality thermal platens without the added costs or complexity associated with cavity machining.
Material Supply as a Core Platen Manufacturing Service
A major differentiator for Venango Machine amongst the competition is their ability and willingness to source and supply all raw steel plate material required for platen manufacturing. As the size, width, thickness, and material composition can vary depending on the end-use, working with an experienced procurer can help save time and money in the manufacturing process. By managing material procurement in-house with our trusted steel supply center partners, Venango ensures consistent plate quality and eliminates uncertainty around material grade, certification, or delivery timelines that can lead to rising costs or missed deadlines.
Venango Machine offers:
- Procuring a steel plate in the correct grade and thickness
- Managing mill orders and freight logistics
- Verifying material certs and traceability
- Preparing plate stock for grinding, machining, and gundrilling
- Ensuring dimensional consistency across single platens or full matched sets
This full material sourcing model allows our customers to offload raw material management responsibilities entirely while ensuring that the finished platen begins with structurally sound, specification-appropriate steel and will perform reliably.
Venango Machine Focuses on Custom-Machined Platens
While there are certain consistent design requirements for platens within the same industry, say plywood or laminate manufacturing, there are few similarities between that application and something like manufacturing high-end composites like carbon fiber. Temperatures, cooling cycles, heating methods, size, and other design characteristics can vary tremendously. For decades, Venango Machine has intentionally avoided high-tolerance mold pocketing and cavity machining to best refine their equipment and services to custom machine platens for industry-specific demands.
This specialization separates Venango from mold shops and aligns them with industrial buyers who need thermal platens—not complex tooling. Two of the more advanced fabrication processes required to produce custom-machined platen are precision surface grinding or Blanchard grinding, and expert gundrilling or deep hole drilling.
Precision Surface Grinding for Large Platens
Venango Machine provides precision surface grinding for large and heavy platens requiring exceptional flatness, uniform thickness, and stable thermal performance. With both Blanchard and precision surface grinding capabilities, Venango delivers the accuracy needed for heated, cooled, or multi-zone platen assemblies. Their process supports reliable mechanical performance, consistent thermal transfer, and repeatable results across multi-plate systems.
Key precision grinding capabilities include:
- Controlled flatness and parallelism on large platen surfaces
- Fine surface finishes using aluminum oxide grinding wheels
- Large-capacity Blanchard and Supertec surface grinding equipment
- Repeatable accuracy for multi-station or multi-component platen assemblies
Gundrilled Heating & Cooling Lines for Thermal Performance
Venango Machine’s deep-hole drilling services complement its grinding capabilities by producing accurate, straight, and smooth internal channels that support overall platen performance. Using advanced 6-axis deep-hole drilling and gundrilling equipment, Venango creates precise features required for hydraulic press platens, thermal channels, and tooling where both internal accuracy and external surface precision are essential.
Key gundrilling and deep-hole drilling capabilities include:
- Drill depths up to 20 feet with controlled tolerances
- Diameters ranging from 0.25 inches to 2.36 inches in mild steel and alloy materials
- Tight diameter accuracy with clean internal surface finishes
- Integrated drilling, counterboring, and tooling without secondary operations
These capabilities support a wide range of thermal processes in composites, laminating, plastics, rubber, and engineered materials.
