What Thickness Precision Can Sheet Extrusion Achieve?

T-Die Engineering and Application-Specific Tolerance

What level of precision can be expected from your sheet extrusion lines?

Our sheet extrusion lines are engineered to deliver exceptional stability and high-precision output. The equipment is designed to consistently maintain a sheet thickness tolerance of within ±5μm (±0.005 mm). This level of precision is achieved through the integration of high-quality, precision-engineered components, such as our proprietary T-dies, which are manufactured in-house to strict quality standards. The inherent stability of our systems ensures that production parameters, once established, are held constant, which minimizes the need for operator readjustments and promotes uniform product quality across the entire production cycle.


Our sheet extrusion lines are engineered for exceptional stability and precision. During production, our machines are designed to maintain a consistent sheet thickness with a deviation of less than ±5μm (±0.005 mm).

This high level of tolerance is achieved through the integration of precision-engineered components, including our in-house manufactured T-dies and advanced process control systems. The stability of our equipment ensures that once production parameters are set, they remain consistent, minimizing the need for frequent readjustments and ensuring uniform product quality throughout the production run.

Sheet Gauge Precision and Production Conditions

Ching Hsing gives a sheet-thickness precision figure of ±5 μm, equivalent to ±0.005 mm. In-house T-die manufacturing and control of the extrusion process are central to the stated precision approach.

The required tolerance should be confirmed for the selected machine, polymer, width and thickness rather than applied to every configuration as an unconditional guarantee. Include those production conditions in the sheet specification when discussing gauge control and acceptance requirements.
