Spiral Baffle Boards (PA6 Nylon with 30% Glass Fiber)

These spiral baffle boards are used inside injection mold cooling channels and flow-control assemblies where you need repeatable turbulence suppression and stable separation of flow paths. The spiral geometry promotes a controlled secondary flow component, which helps reduce uneven velocity distribution and supports consistent thermal performance across the cavity.

Common scenarios include automotive connector and lighting housing molds, where maintaining uniform cooling around multi-part geometries reduces warpage risk. They are also suited for electronics housings with tight dimensional targets, because the PA6 + 30% glass fiber construction improves stiffness so the baffle maintains its functional shape during assembly and handling.

• Separate plates option layouts: integrate the board with compatible plate configurations to simplify maintenance and rework.
• Process equipment with controlled baffles: use the spiral path for better flow control in assemblies that benefit from predictable separation behavior.

This product uses PA6 nylon with 30% glass fiber (a reinforced thermoplastic). The glass fiber fraction increases stiffness and dimensional stability compared with unfilled nylon, while improving wear resistance in sliding or vibration-prone assemblies.

Because it is a thermoplastic baffle board, it is typically manufactured by injection molding or precision molding of the PA6/GF compound, followed by cooling to lock in the final shape. Unlike tool steels, there is no quench-and-temper or HRC hardness specification as the final mechanical performance depends on the molded thermoplastic structure and glass reinforcement level.

• Wear vs. toughness trade-off: higher glass content improves stiffness and abrasion resistance, but can reduce impact toughness versus lower-filled PA6.
• Comparison: compared to plain PA6, PA6/30%GF better resists deformation under handling and improves long-term stability of the spiral flow path geometry.

Select the board by matching the spiral baffle geometry to your mold or assembly channel routing while observing the provided variable ranges. The product’s Dimension D is available at 8, 10, 12, 16, 20, or 25 mm, which corresponds to the key diameter size used to define the baffle’s spiral flow characteristic.

• Dimension L (overall length): choose from 25 to 400 mm to fit the available straight/spiral envelope in your interior cooling layout.
• A (length of straight section): select from 34, 42, or 92 mm to align with the straight run required for your channel entry/exit geometry.

To integrate with your cavity/core requirements, ensure the board does not interfere with fasteners, partition features, or plate boundaries. Note that the Fixed Partition Plate is No, so use the board with compatible separate plates options and verify clearances for assembly tolerance stack-up. If your design relies on snug seating, account for typical thermoplastic molding dimensional variability when setting mating clearances.
