Project Background
A packaging equipment manufacturer required a custom no-crush wheel for use in a high-speed corrugated board production line.
The main challenge was to ensure smooth material conveying while preventing any surface damage or deformation during continuous operation.
Technical Requirements
The solution needed to meet several key requirements:
- High dimensional accuracy for stable assembly
- Reliable anti-crush performance
- Balanced elasticity and load-bearing capability
- Long service life under continuous running conditions
Product Specifications
The customized wheel was manufactured with the following parameters:
- Outer Diameter: 170 mm
- Inner Bore: 90 mm
- Width / Thickness: 50 mm
- Hardness: 65A
- Outer Ring Thickness: 6.20 mm
- Internal Rib Thickness: 3.50 mm
Structural Design
The wheel features a dual-structure polyurethane design, consisting of:
- A soft outer PU ring that ensures gentle, non-marking contact with the corrugated board
- A reinforced internal rib structure that provides mechanical strength and dimensional stability
This structure enables the wheel to maintain both flexibility and durability, which is essential in no-crush applications.
Manufacturing & Quality Control
All critical dimensions were carefully controlled during production to ensure consistent performance and compatibility with the customer’s equipment system.
The hardness of 65A was selected to achieve an optimal balance between cushioning performance and load support.
Result
The customized no-crush wheel delivered stable and reliable performance in operation, ensuring smooth conveying without damaging the board surface.
The solution successfully met the customer’s requirements for both precision and durability in a continuous production environment.
