Technology for material preservation
In plastic recycling, the goal is not just to melt plastic, but to preserve its molecular structure. Standard extrusion destroys polymer chains through excessive heat and friction. Plasmac reverses this paradigm.
Our proprietary Short Screw Technology (SST) and direct-drive systems are engineered to minimize thermal history, ensuring that your recycled pellets maintain properties comparable to virgin material.
Short Screw Technology (S.S.T.)
Low shear, low degradation
Shear stress is the enemy of quality. By utilizing a shorter screw length with a specialized geometry, we melt the polymer rapidly and gently. This significantly reduces the residence time – the amount of time the plastic spends inside the barrel. Less time under heat means less degradation of the polymer chains, preserving the material’s tensile strength and elasticity
Melt Flow Index retention
High shear alters the viscosity of the plastic. Material processed on standard extruders often comes out with a much higher MFI (more liquid) than the input material. Plasmac SST ensures minimal MFI shift. The pellet you produce has the same viscosity characteristics as the scrap you put in, allowing for immediate reuse in critical applications like blown film.
Direct drive efficiency
We believe in transmitting power directly to the process, not losing it in transmission.
AC motors and gearboxes
Plasmac machines eschew belt drives in favor of high-efficiency AC motors coupled directly to oversized gearboxes. This design offers two advantages:
- Energy savings: no power loss through belt slippage or friction
- Maintenance-free: no belts to tension or replace, and significantly reduced vibration
High torque at low RPM
Our screw design is optimized to output high volumes at lower RPMs compared to competitors. Running slower means less wear on the screw and barrel, lower noise levels, and further reduction in the shear stress applied to the material.
Handling volatiles and moisture
Dual diameter technology
For applications requiring volatile removal, we utilize a specialized screw geometry with a decompression zone. This allows gases to escape effectively. When combined with our high-vacuum degassing system, moisture and ink solvents are evacuated before the final metering zone, resulting in solid, void-free pellets even when processing printed films
Filtration excellence
We integrate continuous screen changers that allow for screen replacement without stopping the line. Positioned strategically after the plasticizing zone, these filters remove paper, wood, or non-melting contaminants, protecting the die head and ensuring pellet purity.
Industry 4.0 ready
As part of the Syncro Group, automation is in our DNA. Plasmac machines are not isolated islands; they are connected data hubs.
Total line control
Our PLCs monitor every parameter, from melt pressure and motor load to temperature zones and water flow. This data can be integrated into your factory’s ERP or supervision system via OPC-UA protocols.
Remote assistance
Every Plasmac machine is equipped for remote connectivity. Our engineers can log in securely to diagnose issues, update software, or optimize parameters in real-time, drastically reducing the need for on-site service calls.
Put us to the test: visit our Tech Center
Theory is good, but results are better. We invite you to bring your toughest scrap to our Tech Center in Busto Arsizio.
Run your material on our Alpha or Omega lines. We will measure the power consumption, calculate the output rate, and analyze the final pellet quality together.
