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.

An Architecture of Rigidity, Engineered for Accuracy

Four oversized, hardened, and chrome-plated guide posts with high-performance, self-lubricating bushings ensure superior guidance. This system guarantees even pressure distribution, safeguarding tooling and ensuring consistent part quality for precision molding and die cutting with zero platen tilt.

Thick, solid steel press beds and moving platens, designed with FEA for minimal deflection. Precision-milled and ground to achieve a perfectly flat working surface, these structures ensure dimensionally accurate parts in every cycle, eliminating inconsistencies from flex or distortion.

Command your manufacturing process with a modern Siemens PLC and user-friendly HMI touchscreen. Intuitive controls allow fine-tuning and saving of critical parameters—force, speed, stroke, and dwell time—to optimize cycles 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.
