Our company has been in operation for 11 years and will definitely be your best choice with guaranteed quality and fast delivery
Product Introduction – FUJI PP0341 / PM74506 H12S Head Honeycomb
The FUJI PP0341 / PM74506 is a honeycomb base plate (also known as a honeycomb support or honeycomb bracket) used inside the H12S working head of FUJI NXT series SMT machines. This component provides a lightweight yet rigid structural base for internal head components, helping to maintain mechanical stability and precision during high-speed operations.
Key Features:
Honeycomb Structure: The internal honeycomb pattern offers an excellent balance of strength and low weight, reducing the overall mass of the working head without sacrificing rigidity.
Precision-Machined: Manufactured to exact FUJI specifications for a perfect fit within the H12S head module.
High Durability: Made of corrosion-resistant and high-strength aluminum alloy or composite material, ensuring long operational life even under heavy-duty use.
Thermal Stability: Designed to minimize thermal expansion and maintain alignment accuracy in high-speed, high-temperature environments.
Application:
Specifically used inside the FUJI H12S placement head, a high-speed head model in the FUJI NXT II / NXT III series.
Serves as a mechanical support platform for key internal parts such as valves, nozzles, actuators, and electrical routing.
Part Numbers:
PP0341
PM74506
(Both refer to the same or functionally equivalent part depending on supplier or revision.)
Maintenance Notes:
Rarely requires replacement under normal conditions.
Should be inspected for deformation, cracks, or wear during major overhauls.
Always use genuine FUJI parts to maintain machine precision and safety.

FAQ Guide – FUJI PP0341 / PM74506 H12S Head Honeycomb
1. What is the FUJI PP0341 / PM74506 H12S Head Honeycomb?
It is a precision honeycomb base plate installed inside the H12S placement head of FUJI NXT SMT machines. It serves as a lightweight, rigid support platform for mounting internal components like nozzles, valves, actuators, and sensors.
2. What is the function of the honeycomb structure?
Provides high structural rigidity with minimal weight
Maintains mechanical stability during high-speed operations
Supports the mounting of various internal components in exact positions
Reduces vibration and mechanical distortion, which helps maintain placement accuracy
3. Which FUJI machines use this honeycomb?
The honeycomb plate is used specifically in the H12S head, which is compatible with:
FUJI NXT II
FUJI NXT III
Machines equipped with H12S high-speed working heads
4. What materials is the honeycomb made of?
It is typically made from high-strength aluminum alloy or composite material with a hexagonal honeycomb internal structure to maximize stiffness while minimizing weight.
5. How can I tell if the honeycomb needs replacement?
You should inspect or consider replacing it if:
There is visible deformation, cracking, or corrosion
Internal components no longer align properly
Machine experiences vibration or placement instability
6. Can the honeycomb plate be reused after component upgrades?
Yes, if it is in good condition and structurally intact. However, it must meet all alignment and tolerance standards for the new components being installed.
7. Is the honeycomb plate a wear part?
No, it is not a consumable or wear item under normal conditions. But it may require replacement during major overhauls or after mechanical damage.
8. What components are mounted onto the honeycomb plate?
Typical components include:
Nozzle holders (e.g., AA0MZ00)
Solenoid valves (e.g., AA1CZ00)
Air tubing and pneumatic fittings
