GUP-1 (Golden Uni-Pressor) — Compact Power for High-Accuracy PressingThe GUP-1 (Golden Uni-Pressor) is a compact, high-performance pressing solution designed for precision applications where consistent force, repeatability, and small footprint matter. Combining a robust mechanical design with modern control electronics, the GUP-1 targets small- to medium-scale production environments, R&D labs, and specialty manufacturing where accuracy and reliability are prioritized over sheer throughput.
Key features
- Compact footprint: Designed to fit on benchtops or tight production lines without sacrificing structural rigidity.
- High-accuracy force control: Closed-loop feedback enables precise application of pressing force, minimizing variability across cycles.
- Programmable stroke and dwell: Users can set stroke length, speed, and dwell times for repeatable and optimized processes.
- Modular tooling interface: Standardized mounting and quick-change tooling adapters reduce downtime during product changes.
- Robust safety systems: Integrated protective guards, emergency stop, and configurable sensing for operator safety.
- Data logging and connectivity: Optional digital interfaces (Ethernet/USB/RS-232) and onboard memory record cycle data for quality control and traceability.
- Low maintenance: Sealed actuator systems and easy-access service points minimize maintenance intervals and downtime.
Typical applications
- Electronics assembly (press-fitting connectors, pins, or terminals)
- Medical device manufacturing (assembly of small implants, housings, or watch-like mechanisms)
- Precision watchmaking and micro-mechanics
- Laboratory sample preparation and materials testing
- Prototyping and low-volume production runs requiring tight tolerances
Mechanical and control design
Mechanically, the GUP-1 emphasizes rigidity to ensure that applied force translates predictably into work on the part rather than being absorbed by frame flex. A hardened, precision-ground column and base plate reduce deflection. The press ram is guided by linear bearings or a low-friction rail system that maintains alignment during travel.
Control-wise, the GUP-1 typically utilizes a servo- or stepper-driven actuation system coupled with a force sensor (load cell) and position encoder. A closed-loop controller monitors force and position in real time, enabling multiple control modes:
- Force control: The press applies and holds a target force with specified tolerance.
- Position control: The ram moves to a programmed depth at a set speed.
- Hybrid modes: Position with force limits (useful for inserting fragile components) or force profiles over time.
The control interface is usually a touchscreen with recipe management, allowing operators to save and recall process parameters quickly. Advanced models support integration with PLCs and factory automation systems (IoT-ready options).
Performance specifications (example)
Note: Actual specs vary by model/configuration; these are illustrative.
- Maximum force: 1–5 kN
- Position resolution: 0.01 mm (or better with high-resolution encoders)
- Repeatability: ±0.02 mm / ±0.5% force
- Stroke length: 0–50 mm (configurable)
- Cycle rate: up to several cycles per minute (dependent on stroke and dwell)
- Power supply: 110–240 VAC, single phase (or optional 24 VDC for mobile/benchtop variants)
Tooling and fixturing
The GUP-1’s modular tooling interface usually presents a standard bolt pattern and quick-change adapter plate compatible with common tooling systems. Recommended tooling practices:
- Use hardened inserts or bushings where repeated impact or wear occurs.
- Employ alignment pins and guides for parts with tight positional tolerances.
- Design fixtures to support parts fully under force application to avoid bending or distortion.
- Incorporate part presence sensors or mechanical interlocks when needed for safety and process verification.
Integration and automation
For production environments, the GUP-1 can be integrated into automated lines. Typical integrations include:
- Part feeders (vibratory, bowl, or robotic pick-and-place) to supply components.
- Vision systems to verify orientation and presence before pressing.
- Conveyors or pallet systems to move parts in/out of the pressing station.
- Central PLC or MES connectivity for process orchestration and data aggregation.
Communications options such as Ethernet/IP, Modbus TCP, or Profinet may be offered for seamless factory integration. For small labs, USB or serial logging may be sufficient.
Safety and compliance
The GUP-1 design addresses operator safety and regulatory compliance:
- Light curtains or interlocked guarding to prevent access during operation.
- Emergency stop and safety-rated control circuitry.
- CE/UL compliance options depending on market.
- Configurable limits and software interlocks to prevent over-travel or excess force.
Risk assessments (e.g., per ISO 12100) should be performed during installation and for specific fixtures to ensure safe operation in each use case.
Advantages and limitations
| Advantages | Limitations |
|---|---|
| High accuracy and repeatability in a small footprint | Lower throughput compared with larger, specialized presses |
| Easy integration into automated systems | Force capacity limited relative to industrial-scale presses |
| Lower initial cost and maintenance than heavy hydraulic systems | May require customization for specialized tooling/part geometries |
| Good for small-batch, high-precision work | Not optimized for heavy forming or stamping operations |
Maintenance and support
Recommended maintenance includes periodic calibration of the load cell and position encoder, lubrication or inspection of linear guides, checking fasteners and fixture alignment, and software/firmware updates. Manufacturers typically offer service plans, spare parts kits, and training packages.
Buying considerations
When choosing a GUP-1 configuration, evaluate:
- Required maximum force and stroke length for your parts.
- Desired control modes (force vs. position vs. hybrid).
- Integration needs (communication protocols, I/O).
- Tooling and fixturing compatibility.
- Safety options required for your facility and compliance needs.
- Data logging and traceability requirements for quality systems.
Conclusion
The GUP-1 (Golden Uni-Pressor) fills a niche for organizations that need precise, repeatable pressing in a compact package. It balances mechanical robustness, modern control capabilities, and modular tooling to serve industries from electronics to medical devices. For teams running small to medium production runs or working in R&D settings, the GUP-1 offers a flexible, cost-effective pressing solution that emphasizes accuracy and process control.
