LFT-D molding process (Long-fiber Reinforce Thermoplastic Direct) is a new Long Fiber reinforced thermoplastic composite technology, which is a process technology for the direct online production of long fiber reinforced thermoplastic composite products.
The equipment adopts high pressure accumulator system and servo oil-electric system to achieve rapid pressure building and rapid pressing functions, which brings more possibilities for LFT-D molding technology.
LFT-D Servo Composite Hydraulic Press
Thermoplastic Composite Molding Process
The LFT-D (Long Fiber Thermoplastic - Direct) press is a high-performance machine designed specifically for the direct processing of long fiber-reinforced thermoplastics. It integrates the compounding of glass or carbon fibers with thermoplastic resins (such as PP or PA) and extrudes the mixture directly into the mold for compression molding.
Compared to traditional injection molding or sheet compression techniques, the LFT-D process offers significant advantages in terms of part strength, impact resistance, lightweighting, and cost efficiency. It is widely used in applications requiring high structural performance, such as automotive bumpers, underbody shields, battery trays, and seat components.
Continuous innovation and research and development, PHP(Pengda Hydraulic Press) is committed to the development of LFT-D molding process.

With the growing demand for high-performance composite materials in automotive lightweighting, rail transit, and aerospace industries, industrial production faces unprecedented challenges. Traditional molding technologies often struggle to balance speed, precision, and energy efficiency when handling long fiber thermoplastics (LFT), resulting in limited production efficiency, material waste, and inconsistent product quality. Against this backdrop, the LFT-D Servo Molding Press has gradually become the ideal choice for companies seeking high-performance, efficient molding solutions. The LFT-D Servo Molding Press combines servo motor technology with a precision hydraulic control system, enabling precise regulation of mold pressure, displacement, and speed. This high-precision energy distribution ensures uniform force during the forming process, guaranteeing the structural strength and surface quality of final components. This capability is indispensable for automotive structural parts, aerospace composite components, and high-demand rail transit seating products.
The uniqueness of the LFT-D Servo Molding Press lies in its precise servo-driven system. Unlike traditional hydraulic presses that rely on conventional valve-controlled systems, the servo system can adjust pressure and displacement in milliseconds, achieving dynamic response and precise control. This significantly reduces issues such as material fiber pull-out, bubbles, and misalignment during high-fiber material molding while also extending mold life and ensuring product consistency. Moreover, the high energy efficiency of servo drives helps manufacturers save electricity and reduce production costs, supporting environmentally friendly manufacturing. In addition, the LFT-D Servo Molding Press allows for multi-stage pressure curves and adjustable speed modes to meet the process requirements of different composite materials. For thick plates, large structural components, or complex curved parts, traditional hydraulic presses often face limitations in forming uniformity. The LFT-D Servo Press, with programmable control, can match mechanical parameters at every stage, ensuring optimal product precision and mechanical performance.
