Ching Hsing Machinery provides advanced extrusion solutions engineered for the production of high-value specialty films. Our production lines are specifically designed to process demanding polymers such as polycarbonate (PC), polymethyl methacrylate (PMMA), and thermoplastic polyurethane (TPU). By integrating decades of engineering expertise with in-house manufacturing of critical components, we deliver systems that provide unparalleled precision, stability, and operational efficiency for manufacturers in highly competitive global markets.
PC/PMMA Optical Film Extrusion Lines
Our PC/PMMA Optical Film Extrusion Line is a premier solution for the high-end display, electronics, and automotive sectors. Engineered for producing light guide plates, diffuser films, and IMD films, this system meets the rigorous purity and quality standards required for optical applications. Key technical features include:
- Flawless Surface Quality: Specialized clean-room grade extruders and ultra-mirror finish calendering rolls ensure a flawless surface free from micro-defects.
- Optical Clarity: The line combines the superior transparency of PMMA with the impact resistance of PC, delivering films with high light transmission and excellent structural stability.
- Process Stability: Advanced non-pulsation melt pumps and high-precision filtration systems guarantee an ultra-stable melt flow, ensuring consistent optical properties and thickness uniformity.
TPU Film Extrusion Lines
Designed to address the unique rheological properties of thermoplastic polyurethane, our TPU Film Extrusion Line serves the high-end textile, medical, and automotive industries. This system excels in producing films for applications such as waterproof breathable membranes, medical-grade barriers, and paint protection films (PPF).
- Material-Specific Design: The line utilizes specialized screw designs and precision T-die systems to produce films with superior elasticity, tear resistance, and breathability while minimizing thermal degradation.
- Exceptional Uniformity: We deliver machinery that achieves excellent thickness control and flawless surface finishes, critical for high-performance applications.
- Reliable Operation: The system is equipped with smart automation and specialized cooling rollers to prevent film sticking—a common challenge in TPU processing—ensuring stable, low-maintenance production.
Engineered for Precision and Reliability
At Ching Hsing, we maintain complete control over the quality of our machinery by manufacturing core technologies, including screw designs and T-dies, entirely in-house. This commitment to quality ensures our extrusion lines exhibit extremely high stability during production, with sheet thickness deviation consistently below ±5μm. Our strong customization capabilities allow us to design and build equipment that is 100% compliant with your specific material requirements and factory layout, providing a significant competitive advantage.

TPU Equipment in the Specialty Film Range
The Specialty Film Lines category currently contains the TPU Film Extrusion Line. It processes thermoplastic polyurethane for flexible products including diving suits, waterbeds, windbreakers, snow jackets, shoes and knee pads. The TPU product description emphasizes flexibility, tensile strength and resistance to friction.
The TPU equipment table lists film widths of 900–1,800 mm, thicknesses of 0.015–1.5 mm and output of 100–250 kg/hr. A 20 m/min line speed is listed for this family. Its dimensional range differs from the thicker PET and PP/HIPS packaging-sheet equipment.
Start with the intended flexible product, then compare the film width, gauge and output with the proposed configuration. Ching Hsing manufactures machinery to customer requirements, so application and material selection should accompany a request for the TPU line.
