VMA Introduces V-604B Ultrasonic Double-Hole Punching Machine for Clean Garment Openings
VMA SEWING MACHINE CO., LTD introduces the V-604B Ultrasonic Double-Hole Punching Machine, a practical garment processing solution designed for clean, stable and efficient hole punching applications.
In modern garment production, hole punching is widely used in sweatshirts, outdoor jackets, front plackets and functional garment parts. Traditional punching methods may cause rough hole edges, weak reinforcement, fabric deformation or inconsistent appearance. The V-604B is developed to help garment factories complete high-quality ultrasonic punching with cleaner openings and better finished results.
Designed for Ultrasonic Double-Hole Punching
The V-604B Ultrasonic Double-Hole Punching Machine is designed for garment openings that require clean edge quality and reinforced hole finishing.
It is especially suitable for:
- Sweatshirts
- Outdoor jackets
- Front plackets
- Functional garment openings
- Buttonhole-related opening preparation
- Reinforced double-hole punching processes
By using ultrasonic punching technology, the machine helps create smooth hole edges with reduced burning, no obvious blackening and cleaner finished appearance.

Key Product Advantages
1. Dual-Mode Operation
The V-604B supports seamless switching between single-hole and double-hole modes, allowing factories to process different garment opening requirements with one machine.
2. Integrated Punching and Reinforcing Process
The machine supports cutting and reinforcing in one operation, helping improve production efficiency and reducing repeated manual handling.
3. Clean Finished Hole Edge
Ultrasonic punching helps create smooth garment opening edges, reducing burrs, burning and blackening issues often found in conventional punching methods.
Process and Result
The V-604B follows a clear production workflow:
Step 1: Punching
The garment part is positioned under the punching area, and the machine completes the hole punching process.
Step 2: Clean Opening
The ultrasonic process helps produce a cleaner opening with a smoother edge.
Step 3: Reinforced Opening
The hole area is reinforced to improve durability and reduce edge deformation.
Step 4: Finished Result
The finished garment opening appears clean, stable and suitable for further assembly or final garment finishing.
Technical Parameters

Why Garment Hole Punching Needs Better Processing
Hole punching may look like a small process, but it has a direct impact on the quality and appearance of finished garments. For front plackets, drawstring openings, jacket openings and functional garment parts, poor hole quality can affect both appearance and durability.
Common problems in traditional punching include:
- Rough hole edges
- Burn marks or blackened edges
- Uneven opening size
- Weak hole reinforcement
- Fabric deformation
- Extra manual correction after punching
The V-604B Ultrasonic Double-Hole Punching Machine helps solve these issues by combining ultrasonic cutting and reinforcement, making the process cleaner and more consistent.
Suitable Applications
The V-604B is suitable for garment factories producing:
- Sweatshirts
- Hoodies
- Outdoor jackets
- Sportswear
- Casualwear
- Front placket garments
- Functional clothing with openings
- Garments requiring single-hole or double-hole punching
This machine is especially useful for factories that need stable hole quality, cleaner edge finishing and better appearance consistency in batch production.
Benefits for Garment Factories
Cleaner Garment Openings
The ultrasonic punching process helps create smooth and clean openings, improving the final garment appearance.
Higher Process Efficiency
Punching and reinforcement can be completed in one operation, reducing manual handling and improving production rhythm.
Flexible Production
The machine supports single-hole and double-hole processing, making it suitable for different garment structures and production requirements.
Better Finished Quality
Clean hole edges and reinforced openings help improve garment durability and reduce the need for rework.
Practical for Multiple Garment Categories
From sweatshirts and jackets to plackets and functional garment parts, the V-604B supports a wide range of garment opening applications.
How to Choose an Ultrasonic Hole Punching Machine
When choosing an ultrasonic hole punching machine, garment factories should consider the following points:
Garment Type
Factories should confirm whether the machine is suitable for sweatshirts, jackets, plackets or other garment parts requiring holes.
Hole Type
If the production process includes both single-hole and double-hole openings, a dual-mode machine is more flexible.
Edge Quality
For visible garment parts, clean hole edges are essential. Ultrasonic punching helps reduce rough edges and blackening.
Reinforcement Requirement
Some garment openings need reinforcement to improve durability. Integrated punching and reinforcing can improve process stability.
Production Efficiency
For repeated garment openings, automated or semi-automated punching equipment helps reduce manual processing time and improve consistency.
