The primary driving force behind the development of die shims for plastic profile sheet extrusion molds has been the rise and growth of the plastic profile window and door industry. To this day, plastic windows and doors remain the dominant products manufactured using these die shim-equipped extrusion molds

The feed system of a slot-die coater is fully enclosed—keeping the slurry isolated from the external environment until it is applied onto the foil substrate. The slurry reservoir features a double-layer insulated structure, minimizing the impact of ambient temperature fluctuations on the slurry. This ensures

The thickness gauge instantly measures the flat film thickness and sends the detected signal to the control unit. The control unit processes this signal through computation. When the measured thickness exceeds the preset standard, the system identifies the corresponding screw number. The control unit then instructs

Recent theoretical and practical research—aimed at characterizing the flow behavior of extrusion slot-die coating heads—has leveraged material data and flow modeling to significantly improve our understanding of the processes occurring within these dies. The extrusion slot-die coating head transforms the

Slot-die extrusion coating is an advanced pre-metered coating technology capable of producing highly precise coatings. Today, the lithium-ion power battery industry has widely adopted slot-die extrusion coating for manufacturing battery electrodes. In this process, a slurry with a precisely controlled flow rate enters

The working principle of the coating die used in automatic screen printing plate-making coaters is fundamentally the same, though its specific functions may vary depending on the machine model and manufacturer. On a vertical frame, screen coaters are equipped with devices capable of securely clamping screen frames
