This machine is engineered to deliver consistent performance across diverse materials and die profiles, while prioritizing operator safety and operational efficiency.Whether you’re working with leather, textiles, rubber, foam, plastics, or composite materials, the TW-928(3+1) provides a versatile and robust platform capable of handling complex die cutting tasks with ease. Its advanced automation features, combined with precise electronic controls and ergonomic safety mechanisms, make it a preferred choice for industries seeking to optimize quality, productivity, and workplace safety.

Core Features and Technological Innovations

Automatic Stroke End Setting for Variable Die Heights

One of the TW-928(3+1)’s standout features is its automatic stroke end setting system. In traditional die cutting presses, operators must manually adjust the minimum cutting spot—i.e., the exact height where the press applies pressure—to accommodate varying die heights and thicknesses of materials. This manual adjustment is time-consuming, prone to human error, and can lead to inconsistent cutting quality or premature wear of cutting dies.The TW-928(3+1) completely transforms this process by integrating an automatic stroke end adjustment mechanism. This system dynamically senses the height of the die or material stack and sets the stroke endpoint accordingly, eliminating the need for manual adjustments. This ensures that every cut is executed at the optimal depth, preventing undercuts or overcuts and maximizing die longevity.With this automatic adjustment, the press also protects delicate dies and materials from excessive pressure, minimizing waste and rework.

Electronic Pressure Control Using Circuit Board and Potentiometer

Precision cutting requires precise control of pressing force and timing. The TW-928(3+1) achieves this through an electronic pressure control system governed by a sophisticated circuit board. The circuit board monitors and regulates the hydraulic pressure applied to the cutting operation, ensuring it reaches the maximum required force for efficient cutting without exceeding safe limits.Complementing this is a potentiometer-based pressing time controller. The potentiometer allows operators to fine-tune the duration for which the swing arm applies pressure during each cutting cycle. By adjusting the pressing time, operators can tailor the cutting force application to match different materials and die complexities.The combined use of electronic pressure control and timing adjustment optimizes cutting quality, reduces stress on machine components, and minimizes energy consumption by preventing unnecessary pressure application.

Dual-Hand Switch Safety System for Operator Protection

Operator safety is a critical concern in industrial presses, where inadvertent contact with moving parts can result in serious injury. The TW-928(3+1) addresses this with a dual-hand switch control system designed to safeguard the operator during pressing cycles.This system requires the operator to simultaneously press two separate control switches—one with each hand—to initiate the cutting stroke. This safety feature ensures that both of the operator’s hands are away from the cutting zone, significantly reducing the risk of accidental hand injuries.The switches are ergonomically positioned and require a deliberate, coordinated action to activate, meeting international industrial safety standards and promoting a safe working environment.

Robust Hydraulic Swing Arm Mechanism

The TW-928(3+1) is equipped with a hydraulic swing arm mechanism that allows the upper cutting platen to pivot laterally. This swinging motion facilitates easier placement and removal of dies and materials by the operator, enhancing workflow ergonomics and reducing cycle times.Powered by a reliable hydraulic system, the swing arm delivers consistent and powerful cutting force while maintaining smooth, controlled movement. This hydraulic design reduces mechanical shocks and vibration, contributing to higher machine longevity and more accurate cuts.

Durable Construction with Compact Footprint

Engineered for industrial environments, the TW-928(3+1) features a heavy-duty steel frame built to withstand constant use and heavy loads without deformation. The precision manufacturing of the frame and internal components ensures stable alignment and repeatable performance over the machine’s operational life.Despite its robust build, the machine maintains a compact footprint that optimizes factory floor space. This makes it suitable for production lines with limited space or for facilities aiming to maximize output from available real estate.

Operational Benefits and Performance

Simplified Setup and Fast Changeover

Thanks to its automatic stroke end setting and electronic pressure controls, the TW-928(3+1) dramatically reduces setup times between jobs. Operators no longer need to adjust cutting height or pressure manually when switching dies or material thicknesses.This capability is particularly advantageous in industries with frequent job changes or batch production models. The faster setup leads to increased machine uptime, higher throughput, and better responsiveness to shifting production schedules.

Consistent and High-Quality Cutting Results

The integrated electronic controls and automatic adjustments ensure that the TW-928(3+1) delivers uniform cutting depth and quality throughout production runs. This consistency reduces scrap rates and enhances product reliability, helping manufacturers meet strict quality control standards.By precisely controlling cutting pressure and stroke, the machine prevents damage to delicate materials and dies, maintaining the integrity of complex shapes and fine details.

Significant Material and Cost Savings

The precision of the TW-928(3+1) directly translates into resource efficiency. By eliminating overpressure and optimizing cut depth, it reduces material waste and extends the life of cutting boards and dies.These efficiencies lower operational costs, improve yield, and contribute to sustainable manufacturing practices by minimizing raw material consumption and waste disposal.
