The Benchmark for Industrial Stability and Precision

The 4 post hydraulic press, often called a four column press, is a cornerstone of modern manufacturing for a reason: its design is inherently stable. By guiding the moving platen along four large, rigid columns, this architecture provides exceptional resistance to the off-center loading that can compromise part quality and damage tooling in other press types. It is the definitive platform for applications where precision is paramount.

A Runwind 4 post press is more than just a powerful machine; it is a complete system engineered to maintain precision under the most extreme industrial conditions.

An Architecture of Rigidity, Engineered for Accuracy

Unwavering Platen Parallelism

The system is built around four oversized, hardened, and chrome-plated guide posts. These massive columns are paired with high-performance, self-lubricating bushings that provide a massive surface area for guidance and support. Safeguard your valuable tooling and guarantee consistent part quality. This superior guidance system ensures even pressure distribution across the entire workpiece, which is critical for precision molding, die cutting, and any process with a zero-tolerance for platen tilt.

Massive, Low-Deflection Bed & Platen

The press bed and moving platen are thick, solid steel structures, designed using Finite Element Analysis (FEA) to ensure minimal deflection. After fabrication, they are precision-milled and ground to achieve a perfectly flat and true working surface. Produce dimensionally accurate parts, every cycle. The rock-solid press bed provides a true and stable surface for your most precise work, eliminating the inconsistencies caused by the flex and distortion found in under-engineered presses.

Intelligent, Process-Driven Controls

Every Runwind press is commanded by a modern Siemens PLC with a user-friendly HMI touchscreen. This system provides complete, intuitive control over every aspect of the press cycle. Take complete command of your manufacturing process. Our intuitive controls allow you to fine-tune and save every parameter—force, speed, stroke distance, and dwell time—to optimize your cycle and achieve perfect, repeatable results for every job.

Your Technical Questions on 4 Post Presses

Yes, the terms 4 post press and “four column press” are used interchangeably in the industry to describe the same machine architecture. This design features a bed and slide guided by four large, cylindrical posts (or columns) to ensure maximum stability and parallelism.

Our precision models are engineered to a parallelism tolerance of ≤0.02mm (20 microns) across the platen surface. Our FEA-optimized designs ensure minimal deviation from this tolerance even under full tonnage and moderate off-center loading.

Rigidity is engineered from the ground up. We use heavy, certified steel plate for the crown, bed, and slide. After expert welding, these core structures undergo a multi-day thermal stress-relieving process in a furnace. This critical step removes internal stresses, creating a stable foundation that will not warp or distort over decades of service.

Absolutely. The HMI is designed for a modern, high-mix production environment. You can create, name, and store hundreds of unique recipes. An operator can select a job, and the system will automatically load all parameters—stroke, pressure, dwell time, etc.—drastically reducing setup time and eliminating errors.

Build on a Foundation of Unquestionable Stability

Your tools are precise. Your process is demanding. Your final product must be perfect. You need a press that provides a foundation of engineered stability that you can rely on, cycle after cycle, year after year. Partner with the experts who share your obsession with precision and build the 4 post press that will become the most reliable and profitable asset on your factory floor.

  • Protect your multi-thousand-dollar tooling with superior parallelism.
  • Achieve unparalleled part quality and consistency with a rigid, non-deflecting frame.
  • Maximize your process control and automation capabilities with an advanced PLC system.
