Core Design Features of the 200-ton Three-Cylinder Large-Table Luggage Hot Press

The 200-ton three-cylinder large-table luggage hot press is a professional and efficient production tool for manufacturing luggage shells and suitcase panels. It is a high-performance hydraulic press specifically designed for the hot pressing process of luggage shells, suitcase panels, and large plastic sheets. Utilizing a three-cylinder structure and an extra-large worktable, it ensures uniform pressure within the forming area, making it particularly suitable for integrated hot pressing, stretching, and shaping operations on ABS, PC, PP, and composite materials. Below is a sharing from Jianlong Hydraulic Technology for your reference!

1. Three-Cylinder Synchronous Pressing System (Core Advantage)

1.1 Stable Structure and Balanced Pressure: The central main cylinder, in conjunction with the two auxiliary cylinders on both sides, operates in three-point linkage, achieving extremely uniform pressure distribution within an extra-large worktable area (such as 2000×1500mm or customized), completely solving common quality problems in luggage panel forming such as "warping, incomplete edges and corners, and uneven thickness."

1.2 Independently Adjustable: The pressure of the auxiliary cylinders on both sides can be individually fine-tuned, adapting to asymmetrical molds or special process requirements, offering exceptional flexibility.

2. Large Table and Hot Plate System

2.1 Extra-Large Working Area: The table size can be customized to meet specific needs, allowing for the simultaneous placement of multiple molds or the molding of large panels, significantly improving production efficiency.

2.2 High-Efficiency Hot Plate Heating: The upper and lower hot plates are made of high-temperature resistant alloy steel, with built-in multi-zone temperature-controlled heating tubes (or oil heating channels), coupled with a PID intelligent temperature control system, ensuring a surface temperature difference of ≤±3℃, guaranteeing uniform material heating and consistent molding quality.

2.3 Rapid Heating: Optimized hot runner design ensures rapid heating and energy savings.

3. Precision Temperature and Pressure Control

3.1 Multi-Segment Temperature Control: Multiple temperature profiles, including heating and holding, can be set to meet the process requirements of different materials (e.g., ABS requires 110-130℃, PC requires 140-160℃).

3.2 Multi-stage Pressure Control: The system can achieve a complete process cycle of "rapid mold closing → low-pressure contact → slow pressurization → segmented pressure holding → pressure release," effectively controlling material flow and reducing internal stress.

4. Humanization and Automation

4.1 Mold Transfer Mechanism (Optional): Equipped with a servo motor-driven mold transfer trolley or robotic arm interface, facilitating quick replacement of heavy-duty molds and reducing labor intensity.

4.2 Protection and Safety: Multiple protections including four-sided light curtain or safety door interlocks, dual-button start, and hydraulic system safety valve assembly, meeting CE safety standards.

4.3 PLC + Touch Screen Control: User-friendly human-machine interface, capable of storing hundreds of mold parameters for one-click recall.
