Step-by-Step Demo: Printing an Ovoid Thermal Flask

This is the actual process our English-speaking engineers will walk you through on your private video call.

Step 1: Machine Setup & Parameter Adjustment

Before printing begins, we adjust the machine for the specific ovoid thermal flask. This includes setting the air pressure (0.4-0.6MPa), adjusting the worktable height, printing head height, and stroke length to match the flask’s curvature.

The JST-R400-CSM uses HIWIN precision linear guides for smooth vertical adjustment, driven by a servo motor and reducer. The entire screen frame and print head move as one unit, ensuring perfect parallel alignment with your product.

Step 2: Custom Screen & Stencil Installation

We install a 600×400mm screen frame with your custom logo design. The screen is tensioned uniformly on a CNC-machined frame — because inconsistent tension directly affects registration accuracy.

For this ovoid thermal flask, we’re printing a multi-color logo. Each color requires a separate screen, and we use the LEUZE sensor to align each layer with micron-level precision.

Step 3: Squeegee & Flood Bar Installation — Curved Surface Adjustment

The squeegee must match the flask’s curvature for uniform ink transfer. We install the flood bar and squeegee, then manually adjust the squeegee angle to follow the ovoid contour. This ensures the entire printed area receives even pressure — no thin spots, no smudging.

The pneumatic squeegee drive provides consistent downforce on every cycle, eliminating the variability of manual pressure.

Step 4: Custom Fixture & Product Loading — The Precision Advantage

This is where the JST-R400-CSM truly shines for non-standard shapes. The ovoid thermal flask is mounted onto a custom CNC-machined fixture that holds it firmly and ensures the printing surface is perfectly parallel to the screen.

This fixture was machined in-house on our own CNC equipment — one of 10 high-precision centers with ±0.01mm accuracy. For your products, we can design and machine custom fixtures based on your samples.

For standard cylindrical products with rigid walls, the machine comes with universal fixtures that work out of the box — no custom fixture required.

The operator loads the flask manually, then steps on the foot pedal to start the automatic print cycle.

Step 5: Ink Application & Registration

We pour UV screen printing ink into the screen frame and begin the printing cycle. The machine automatically moves the screen frame left and right via servo motor while the squeegee presses down. Simultaneously, the rotary servo motor rotates the flask in sync with the screen movement — this relative motion transfers the ink through the stencil onto the product surface.

For multi-color printing: After the first color, we manually change the screen for the second color. The LEUZE optical contrast sensor detects the already-printed logo position and automatically registers the next layer — no manual alignment guesswork. This sensor is what makes 2-10 color overprinting practical and precise.

Step 6: Finished Product — Sharp, Registered, Production-Ready

After printing, the operator removes the flask for curing. The result: a sharp, opaque logo with 0.1mm registration accuracy, properly positioned on the curved surface. No distortion, no edge blur.

Curing options:

• UV ink → Requires a UV curing lamp (sold separately) for instant drying
• Solvent ink → Air dries in 2 hours (surface) / 24 hours (fully cured)
• Solvent ink + IR oven → Optional IR curing oven reduces drying to 1-5 seconds

Every JST-R400-CSM undergoes 48-hour continuous production testing before shipping to ensure batch-to-batch consistency.
