Shredder V2.1 Regular Steel
Includes;
- 74 laser cut parts in regular steel S235 . According to Precious Plastic 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).
- 2 units UCFL204 bearings according to Precious Plastic specifications (bearings fit on the shaft and on the laser cut parts).
- Regular steel nuts and bolts.
- Precious Plastic specifies stainless steel. We offer alternative ways in regular steel, at a lower cost than stainless steel.
- To assemble the shredder, you will have to complete several steps. This kit requires manual assembly and basic mechanical operations—it is not a plug-and-play system. Please check the assembly instructions.
Options
The kit offers multiple configuration options
We have a option, where you can order our “Evolution Shaft”. Based on the original Precious Plastic design, we have modified it by removing the excess and adding a keyway (key included).
We have an option with the 4 Conic Drill. This operation is essential for the assembly of the machine. Where the head of the countersunk screws are inserted. You can decide whether you make them yourself or we send them to you already made.
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. Precious Plastic recommends a 380 V, 2.2 kW, three-phase motor.
- Gearbox
- Coupling between gearbox and shaft
- Sieve
- Electrical and control components

Data Sheet
In this section, you will find all the technical documentation of our “Shredder V2.1 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.
All our bolts are manufactured in grade 8.8 or 10.9 (EN ISO 898-1), with zinc-plated, galvanized, or black oxide finishes, offering high strength and durability.

Optionally, we offer to perform countersinking: where the heads of the countersunk screws are inserted from the inside of the machine. This way, the screw heads will not come into contact with the blades.
Shaft for Shredder V2.1, manufactured from F-122 regular steel.
Based on the original Precious Plastic design, with significant improvements:
We removed the excess shaft length to enhance safety.
A keyway has been added to facilitate connection with the gearbox (recommended only for users with advanced mechanical skills)
Tips
In this section, we provide a series of recommendations and tips, which we hope will be useful to you.
Coupling
To connect the shredder shaft to the gearbox, we recommend using a flexible coupling
Improved Safety
In case of jamming, the shaft will slide on the bushing, avoiding unwanted and dangerous over-tensioning. The bushing includes a keyway (only for users with advanced mechanical knowledge).
Prolong the life of your shredder
It absorbs minor misalignments between the shaft and the gearbox, thereby reducing vibrations and fatigue stresses
Improve efficiency
The motor will run more evenly, minimizing power surges
Watch this video to learn how to insert the blades onto the shaft—no sanding required.
