Custom CNC-Machined HPL Mounting Plates & Insulating Electrical Panels

At SRT Plastics, we provide precision-engineered HPL mounting plates and phenolic laminate panels designed specifically for the rigorous demands of switchgear, control cabinets, and transformer stations. Our custom HPL (High-Pressure Laminate) solutions offer exceptional dielectric strength and mechanical rigidity, providing a safe, electrically insulating base for critical power distribution components. Every panel is custom-machined to your exact technical drawings using high-speed CNC drilling and routing, supporting full compliance with the EU Machinery and Low Voltage Directives. Whether for rapid prototyping or large-scale series production, our HPL components facilitate safe, compact layouts and streamlined on-site assembly for engineers across Europe and the UK.

Technical Fabrication & Material Performance

To ensure reliability in high-voltage and industrial automation environments, our HPL fabrication process focuses on extreme dimensional stability and moisture resistance. Our facility is equipped to handle complex machining requirements, including precision countersinks, custom labeling, and integrated cable entries. Explore our core technical service pillars below to see how our HPL solutions support your electrical engineering projects.
  • Electrical Insulation and Rigidity

    Electrical Insulation and Rigidity

    HPL panels for switchgear, control cabinets, and transformer stations.

    HPL provides the stiff, electrically insulating base electrical systems need. Panels keep dimensional stability, resist moisture and chemicals, and support secure fasteners. Ideal for switchgear backplates and mounting boards, they allow safe, compact layouts while meeting EU and UK standards today.

  • Custom Machining & Clean Finishing

    Custom Machining & Clean Finishing

    CNC drilling, routing, countersinks, labeling, edging, and chamfers.

    We manufacture HPL panels to drawing with precise CNC machining. Services include hole patterns, slots, cut-outs, threads, countersinks, legends, and edge finishing for safe handling. Tight tolerances keep parts aligned on site, saving assembly time and ensuring consistent and reliable quality always.

  • Rapid Supply and European Delivery

    Rapid Supply and European Delivery

    Stocked HPL, quick fabrication, and shipping across the EU and the UK.

    We keep common HPL grades and thicknesses on hand to minimize lead time. Panels are cut, machined, labeled, and packed for safe transit, then shipped to your site across the Benelux, wider EU, and the UK. We support prototypes and series, provide documentation, and align delivery with your schedule.
