Finding the right plastic shredder manufacturer is not simply about comparing machine prices.
A shredder is often the first major size-reduction stage in a plastic recycling plant. Its rotor design, cutting system, feeding method and output size can directly affect the performance of downstream crushing, washing and pelletizing equipment.
Today, the global market includes both specialist shredder manufacturers and companies capable of supplying complete plastic recycling systems.
Based on industry experience, product range, plastic recycling applications, engineering capabilities and global market presence, here are six plastic shredder manufacturers worth knowing in 2026.
Note: This list is intended as a buyer reference rather than an absolute technical ranking. The best shredder depends on your material, capacity, required output size, downstream process and investment budget.

Company: Zhangjiagang AMSTAR Machinery Co., Ltd.
Country: China
Website: https://www.plasticrecyclingmachine.net/
Company Overview
AMSTAR approaches plastic shredding from a slightly different direction.
While several manufacturers above specialize primarily in shredding or size reduction, AMSTAR focuses on complete plastic recycling machinery and recycling lines.
Its shredder range includes single-shaft and double-shaft plastic shredders designed for different materials and production requirements.
Typical applications include:
- HDPE and PP rigid plastics
- Plastic lumps and purgings
- PE/PP film

What Type of Plastic Shredder Do You Need?
Before comparing plastic shredder manufacturers, first determine what kind of material you need to process.
| Plastic Material | Typical Shredder Solution |
| Plastic Film & Bags | Single Shaft Shredder |
| HDPE / PP Rigid Plastic | Single or Double Shaft |
| Plastic Lumps & Purgings | Heavy-Duty Single Shaft |
| Large Plastic Pipes | Pipe Shredder / Horizontal Shredder |
| Bottles & Containers | Single or Double Shaft |
| Bulky Industrial Plastics | Double Shaft Shredder |
The correct shredder also depends on throughput, feeding size, required output size and downstream equipment.
Single Shaft vs. Double Shaft Plastic Shredder
One of the most common questions when buying a plastic recycling shredder is whether to choose a single-shaft or double-shaft design.
| Single Shaft Shredder | Double Shaft Shredder |
| More controlled output size | Strong primary shredding |
| Usually equipped with screen | Normally no sizing screen |
| Hydraulic pusher feeding | High-torque twin rotors |
| Good for film, lumps and rigid plastic | Good for bulky and irregular waste |
| Often used before granulation | Often used for primary size reduction |
Neither design is automatically better.
The right choice depends on what enters the shredder and what needs to come out.
How to Choose a Plastic Shredder Manufacturer
Price should not be the only factor.
When requesting quotations, compare these six points:
1. Material experience
Has the manufacturer actually processed your type of plastic?
2. Real capacity
Ask for throughput based on your material, not just the theoretical maximum.
3. Rotor and blade design
Different materials require different cutting geometries.
4. Wear parts
Check blade material, expected wear life and replacement cost.
5. Downstream compatibility
The shredder output should match the granulator, washing line or pelletizing process.
6. After-sales support
Check spare parts availability, technical support, commissioning and documentation.
Which Plastic Shredder Manufacturer Is Best?
There is no single answer.
For buyers prioritizing premium European shredding technology, manufacturers such as WEIMA, Lindner, Vecoplan and UNTHA are established choices.
For companies focused specifically on plastic size reduction, ZERMA offers an extensive shredder and granulator portfolio.
For recyclers that need the shredder to work as part of a complete plastic recycling line, AMSTAR offers another approach by integrating shredding with crushing, washing, separation, drying and pelletizing.
Ultimately, the best plastic shredder manufacturer is the one that can demonstrate that its machine works with:
Your Material + Your Capacity + Your Required Output + Your Downstream Process
—not simply the manufacturer with the largest shredder or the lowest price.
