Shredder V3.3
Includes;
- Laser cut parts in regular steel S235 . According to Precious Plastic Shredder V3.3 drawings. PP Capi Spain has created the third revision of the original drawings, and we have improved the manufacturing tolerances facilitating the assembly.
- 1 shaft made of regular steel F-112. According to Precious Plastic drawings (laser cutting parts fit onto this shaft). With keyway included
- 2 units UCFL206 bearings according to Precious Plastic specifications (bearings fit on the shaft and on the laser cut parts).
- Laser-cut parts for the sieve holder and sieve (sieve thickness: 1.5 mm, holes diameter: 8 mm o 4 mm).
- Regular steel nuts and bolts.
All laser cutting parts are made of regular steel.
If you would like a variant with wear-resistant steel blades, please do not hesitate to contact us, and we will provide you with the price and delivery time.
We include parts for the sieve holder. If you wish to use it, you will have to weld it.
The parts are supplied unfiled, so you will need to file and adjust them to the final size.
⭐ Advantages and Improvements
This new version introduces the following improvements compared to Shredder V2.1.
No welding needed, making assembly much easier
More robust 36 mm hexagonal shaft
Upgraded bearings for increased strength. D 30 mm
Shaft included keyway
Upgraded thicker side parts. 10 mm
Approximate weight: 21 kg / 46.3 lbs
⚙️ Options
The kit offers multiple configuration options
We offer a variant with the four M16 threads already made—an essential step for assembling the machine, as these threads are where the bearing bolts are inserted. You can choose to carry out this operation yourself or have us deliver the plates with the threads already completed.
We have an option with the sieve with holes D= 8 mm (e = 1,5 mm, 149x149 mm) or with the sieve with holes D= 4 mm (e = 1,5 mm, 149x149 mm).
We also supply the individual components separately, according to your requerements.
🛠️ Assembly Instructions
With our kit you would NOT get the complete shredder. In order to have the complete shredder, you would need the following items;
- Hopper
- Support base
- Electric Motor
- Gearbox
- Coupling between gearbox and shaft
- Electrical and control components

📐 Data Sheet
In this section, you will find all the technical documentation of our “Shredder V3.3 Regular Steel”.
- In Rev3, we have introduced minor changes in the designs, correcting small errors and improving the original drawings, in order to facilitate a better fit between parts.
- All our parts are made from S235 regular steel (or a similar grade, depending on availability)
- All parts are manufactured using laser cutting technology
- This technology enables the production of parts with high-quality finishes and excellent tolerances.
Shafts based on the original Precious Plastic design, manufactured from F-112 (or F-114) regular steel using CNC (Computer Numerical Control) technology.
This process allows for high-quality surface finishes and excellent manufacturing tolerances.
Bolts and nults
Heavy Metrics: Includes 4 high-tensile M16 structural bolts and 6 housing tensioner through-bolts.
KM7 Locknuts: Premium M35 metric slotted locknuts for a tight, millimeter-perfect securing of the shaft.
Calibrated Tensioners: M10 metric threaded through-rods cut to the exact length for a rigid and reliable interlocking of the steel plates.
Full Hardware Set: Supplied with all the thick flat washers and nylon locknuts required for a permanent structural assembly.
Industrial Grade: Fasteners carefully selected to endure continuous mechanical vibrations and high motor torque.
- Here is a Shredder V3.3 assembled
UCFL-206 Units: Two self-aligning bearing assemblies engineered to absorb the heaviest forces and radial loads.
Flanged Housing: Heavy-duty grey cast iron housing featuring two symmetrical fixing holes for structural M16 bolts.
Set Screw Locking: The widened inner ring of the bearing includes two Allen set screws to securely grip the 30 mm shaft and prevent slippage.
Dust-Tight Sealing: Equipped with reinforced rubber seals that prevent plastic dust or impurities from entering the internal bearing races.
Easy Maintenance: Includes external grease nipples to ensure quick lubrication and extend the overall lifespan under continuous operations.
Sieve Selection (Filtering Sieve):
D = 8 mm Sieve (High Speed): Engineered to optimize your workshop’s workflow. It allows faster material passage, resulting in higher shredding speed per hour. Perfect if you need to process large volumes of plastic quickly.
D = 4 mm Sieve (Maximum Filtering): Designed for high-precision projects. It delivers a much smaller and uniform shredded plastic size, ideal for directly feeding injection machines or filament extruders without jamming.
Interchangeable & Robust: Both sieves are laser-cut from high-strength carbon steel, guaranteeing a perfect millimeter-accurate fit inside the shredder’s bottom drawer.
- 🛠️ Metric Machining: We perform 4 precise M16 metric threaded machinings (2 holes per side housing plate) using specialized workshop equipment.
- 🔩 Bearing Alignment: These threads are specifically designed for inserting the structural M16 bolts that secure and fasten the shredder bearings [INDEX].
- 🔧 Direct Assembly: Your kit arrives ready to interlock, allowing you to move directly to the bolting stages with the peace of mind that all thread pitches are 100% accurate, clean, and perfectly aligned.
