Hung Tuan Piston Cylinder liner ( Outer Bar) Three Part piston

Vietnam Piston Cylinder (Outer Bar) – 3 Part for Hung Tuan Agarbatti Making Machine

The Vietnam Piston Cylinder (Outer Bar) – 3 Part is a specialized component designed for high-performance Hung Tuan Agarbatti Making Machines, which are widely used for producing incense sticks with high speed and precision. This three-part piston cylinder assembly is engineered in accordance with Vietnamese machine specifications, renowned for their durability, efficiency, and superior output quality.

🔧 1. Purpose and Functionality

The outer bar piston cylinder assembly functions as the core extrusion system in the agarbatti making process. It compresses the agarbatti paste (masala) and extrudes it through the die, forming sticks with consistent density and shape, either with or without bamboo.

This three-part design ensures:

• Efficient pressure distribution

• Easy maintenance and cleaning

• Precision in extrusion

• Compatibility with high-speed operations

🧩 2. Three-Part Construction Breakdown

a) Outer Cylinder (Main Body/Barrel)

• Material: High-grade Hardened Steel or Stainless Steel (SS304).

• Design: Cylindrical housing with a smooth bore for minimal friction.

• Function:

  • Acts as the chamber where the piston moves back and forth.

  • Maintains the pressure required to extrude the paste.

  • Supports high-pressure, high-temperature working conditions.

b) Inner Piston (Ram/Plunger)

• Material: Tempered Steel or chrome-plated alloy steel for enhanced strength.

• Finish: Polished surface to reduce wear and allow smooth motion.

• Function:

  • Moves inside the outer cylinder to compress and push the agarbatti paste.

  • Designed with high precision to maintain tight tolerance and prevent paste leakage.

  • Works in coordination with the crank or pneumatic system depending on the machine type.

c) Rear Cap/Retainer (Guide Cap or End Block)

• Material: Steel or cast alloy, often zinc-coated for corrosion resistance.

• Function:

  • Seals the rear side of the cylinder.

  • Often includes guide bushings or bearing seats for piston alignment.

  • May house the connection for push rod or cam mechanism in manual/semi-auto models.

  • Easily detachable for maintenance or piston replacement.

⚙️ 3. Key Features

• Vietnam-Origin Design: Optimized for the Hung Tuan series, offering better extrusion quality compared to local alternatives.

• Three-Part Ease: Each part is independently replaceable, reducing maintenance cost and downtime.

• Precision Fit: Tight machining tolerances prevent loss of paste pressure and ensure uniform stick output.

• Corrosion-Resistant: Designed for long-term use even in humid, sticky, and dusty environments.

• Compatibility: Fits seamlessly in all standard Hung Tuan or Vietnamese-style machines used across India and Southeast Asia.

🛠️ 4. Installation & Maintenance Tips

• Lubrication: Regularly lubricate the piston to prevent frictional wear.

• Cleaning: Clean the internal cylinder and piston daily to avoid paste buildup.

• Inspection: Check for cracks or scoring marks on the piston and cylinder wall.

• Replacement: Individual parts can be replaced without disassembling the entire machine.
