PU Guide Block – End Stop for Bag Clamping Mechanism
(Polyurethane Block for Industrial Bagging Equipment)
The PU technical block (Shore 70A) is a specialized engineering plastic component manufactured by Anh Trí Tuệ based on the requirements of bagging plants. It is used in the bag clamping mechanism of industrial bagging machines, where it stabilizes the clamping arms, guides movement, and protects metal surfaces from wear during continuous operation.
- Function & Role in the Bag Clamping Mechanism
The PU block is installed at key contact points of the clamp arms and guide rails, providing the following functions:
- Guides the movement of the clamp arms, ensuring accurate open–close motion.
- Acts as an end stop, absorbing impact when the clamp reaches the end of its stroke.
- Reduces friction and prevents scratching of metal surfaces during repeated clamping cycles.
- Stabilizes clamping force, ensuring the bag mouth is held firmly during filling.
- Reduces operating noise, improving smoothness of the mechanism.
- Protects the machine frame from wear or deformation caused by metal-to-metal impact.
The block features a distinctive stopper lip and two mounting holes, ensuring stable installation in high-speed clamping assemblies.
- Real Applications in Bagging Equipment
This PU component is widely used in:
- Automatic and semi-automatic bagging machines
- Bag filling and weighing systems for agricultural products
- Fertilizer, chemical, and powder bagging lines
- Cement, minerals, and bulk material packaging machines
- Bag clamping units and bag holder mechanisms
- High-speed production lines requiring precise clamping
International manufacturers such as Newlong, Haver & Boecker, Paglierani, and Wuxi also apply similar PU guide/stop blocks in their clamping assemblies.
- Why PU Shore 70A Is Ideal for Bag Clamping Systems
Polyurethane Shore A 70 ±5 provides the ideal balance of elasticity and durability:
- Excellent wear resistance, suitable for repetitive motion.
- Moderate elasticity, effectively absorbs impact without cracking.
- Does not damage bag material, especially PP/PE woven bags.
- Performs well under dynamic loads and vibration.
- Smooth surface and easy to clean, resistant to dust and product residue.
- Protects metal components and prolongs equipment service life.
