Extrusion
DICO GROUP: Contract Manufacturing of Extruder Components and Subassemblies
Extrusion is a key process in shaping plastic materials, enabling the production of a wide range of items, from technical profiles and packaging films to tubes, sheets, and automotive components.
In a competitive and fast-changing market, extruder and extrusion line manufacturers rely on partners who can deliver precise engineering, consistent quality, dependable lead times, and customized solutions.
DICO GROUP serves as a trusted contract manufacturing partner, producing structural components, mechanical assemblies, and critical subsystems for extruders of any configuration, all built to exact design specifications and tight tolerances.
Plastic Extrusion: Why Precision Components Matter
Extrusion is a continuous process where plastic is carefully melted and pushed through a heated barrel by a rotating screw, then shaped by a die into its final profile.
This technology is prized for its high productivity, reliable operation, and versatility across a wide range of polymers.
Meeting these demands requires mechanical components built to tight tolerances, made from high-performance materials, and finished to ensure thermal stability, wear resistance, and perfect conformity with the manufacturer’s design.
What an Extruder requires
the DICO GROUP approach
At the core of every extrusion line is the screw-barrel assembly, supported by gearboxes, heating and cooling units, flanges, and heads.
To ensure reliable operation, every component must meet exacting standards:
- Precision machining on hardened steels or specialty alloys
- Heat or surface treatments where needed
- Perfect screw-to-barrel alignment
- Flat, perfectly aligned contact surfaces
- Resistance to pressure, temperature, and wear
- Flexibility for special configurations (single-screw, co-rotating twin-screw, modular setups)
Increasingly customized extrusion lines, including IoT sensors, interchangeable modules, and complex geometries, require a production chain that can respond quickly to manufacturers’ designs while maintaining short lead times and high quality.

DICO GROUP: Your Technical
Partner for Plastic Extruder Manufacturing
DICO GROUP delivers contract manufacturing for the mechanical components,
functional assemblies, and subsystems that form the extruders designed by our clients.
Our Expertise Includes:
- Co-Engineering and Technical Support
- High-Precision Machining
- Subsystem Assembly Ready for Integration
- Plastic Component Production via Extrusion
Co-Engineering and Technical Support
We collaborate directly with manufacturers’ engineering teams to optimize designs, tolerances, surface treatments, and machining processes—reducing lead times and minimizing production risks.
High-Precision Machining
With over 40 CNC machining centers and specialized departments for deep and complex operations, we produce:
- Barrels and screws
- Flanges and heads
- Gearboxes and mechanical components
- Preassembled submodules ready for integration
Each component undergoes rigorous dimensional inspections and verification using advanced metrology systems.
Subsystem Assembly Ready for Integration
We provide fully tested, preassembled modules that can be installed directly into manufacturers’ production lines.
Plastic Component Production via Extrusion
Where required, we operate in-house extrusion lines to produce finished or semi-finished plastic components with tight tolerances and precisely controlled surfaces.
This capability allows manufacturers to outsource both mechanical and plastic components while keeping a single point of contact for the entire process.
Why Partner with DICO GROUP for Extruder Manufacturing
Partnering with DICO GROUP gives you:
- A single point of contact for both the mechanical and plastic components of your extruder
- Seamless alignment with the manufacturer’s design
- Reliable, repeatable precision, even for complex or custom batches
- Predictable lead times, backed by fully digitalized processes and an in-house production chain
- Consistently high quality, verified through advanced 3D inspections
Our strength lies in transforming complex designs into functional, reliable components, preserving design integrity and delivering exceptional performance.
