From tube to finished component: products and machining

Uni-Mecc specializes in the production of bushings, spacers, and eyelets made from tube, exclusively manufactured according to customer drawings.

Starting from steel, stainless steel, aluminum, and other materials, we manage the component from the cutting phase through to finishing, delivering parts ready for assembly in automotive applications and other industrial sectors.

Our machine park allows us to cut tubes with an outer diameter from 10 to 110 mm and produce components with lengths from 13 to 350 mm, covering a wide range of dimensional requirements.

EYELETS

Uni-Mecc tube eyelets are cylindrical components designed to create a robust fastening point or, when required, a controlled joint area. Thanks to tube processing, they offer a compact and durable solution, suitable for integration into assemblies requiring mechanical reliability, repeatability, and high-quality finishing. They are often used in combination with internal bushings, pins, or elastic elements to improve smoothness, durability, and performance under stress.

They are particularly suitable when the application requires connections between parts that must absorb vibrations, compensate for small misalignments, or manage cyclic movements. For this reason, they are used in solutions where both dimensional precision and cutting and finishing quality are critical, especially in the most “sensitive” assembly points.

They can be used, for example, in:

  • anti-vibration components and elastic supports
  • suspension systems and shock absorbers
  • connection points between frames and mechanical subassemblies

Based on customer drawings, we can manage:

  • different internal and external diameters within the available cutting range
  • thicknesses and lengths ranging from 13 to 350 mm
  • chamfering, deburring, and dedicated finishing operations

BUSHINGS

Tube bushings are key components for guiding and supporting rotational or linear movements, reducing friction and wear between contacting parts. Manufacturing from tube allows optimized material usage and the production of functional and versatile components, suitable for various assembly configurations and load levels.

Within a mechanical assembly, bushings often play a “silent” but critical role: they ensure centering and stability, protect moving parts, and contribute to consistent performance over time. Depending on the application, they can be designed to improve sliding, ensure precise fitting, or act as an interface between metal and elastic components, enhancing system behavior under vibrations or repetitive cycles.

Typical applications:

  • support and guidance for shafts, pins, and joints
  • interface between metal parts and elastic components
  • centering and spacing elements within mechanical assemblies

Depending on application requirements, we can provide:

  • dedicated dimensional tolerances on diameter and length
  • additional machining operations (turning, grooves, chamfering, threading)
  • material selection based on loads, environmental conditions, and type of coupling

SPACERS

Tube spacers are components designed to define and maintain distances, center-to-center spacing, and alignment between assembled parts. They are particularly useful when distance precision affects the correct functioning of the assembly, flatness, parallelism, or assembly repeatability. Manufactured from tube and supplied ready for assembly, they represent an efficient solution to ensure dimensional consistency and finishes aligned with the intended application.

In assembly lines, especially in serial production, it is essential that spacers are uniform, properly deburred, and precisely cut: this reduces downstream processing time and improves the perceived quality of the final product. Depending on specifications, spacers can also be managed with dedicated batch and packaging solutions, facilitating integration into automated or semi-automated processes.

They are used, for example, in:

  • frames and metal structures
  • complex mechanical subassemblies
  • brackets, supports, and assemblies where a constant distance must be ensured

Based on the project, we can provide:

  • spacers with different lengths within the range 13–350 mm
  • cutting with different finishing quality levels depending on the application
  • components with dedicated batch management and packaging for automated lines

PROCESSED MATERIALS

Certified materials, consistent results

CARBON STEEL

Excellent performance-to-cost ratio

Good mechanical strength and machinability

Ideal for high volumes and structural components

ALUMINUM

Lightweight (reduces overall assembly weight)

Good machinability and surface finish

Good corrosion resistance in many applications (depending on the alloy)

 

STAINLESS STEEL

High resistance to corrosion and humidity

Excellent stability in critical environments (washing, condensation, outdoor use)

Good aesthetic and functional durability

OTHER ALLOYS

Allow the component to be tailored to specific requirements: strength, toughness, wear, temperature, etc.

Possibility to optimize performance or durability in specific conditions

 

Uni-Mecc mainly works with selected tubes to ensure dimensional consistency, good machinability, and finishes aligned with customer specifications. Depending on the project and the function of the component, we mainly use:

  • carbon steel
  • stainless steel
  • aluminum
  • other alloys compatible with the cutting and finishing processes used in-house

Material selection is never “standard”, but defined based on what the component is required to perform over time. We therefore evaluate:

  • operating conditions (loads, environment, presence of humidity/chemical agents, temperatures)
  • type of coupling (with rubber, plastic, metal, etc.)
  • required durability and performance targets (strength, stability, wear, fatigue behavior)

Upon request, we support customers in the selection of the most suitable material, starting from the component’s function within the assembly and balancing performance, required machining, and costs.

TYPES OF MACHINING

From tube to finished component

Our production process starts from tubes supplied in 5–6 meter bars and develops through several stages, configured according to the required final product.

In-house cutting range

  • outer diameter: from 10 to 110 mm
  • component length: from 13 to 350 mm

The main operations include:

  • tube cutting with parameters set according to material, diameter, and required finishing quality
  • deburring and edge finishing, with different solutions for structural or aesthetic components
  • dimensional and visual inspections based on plans agreed with the customer
  • packaging and logistics designed according to assembly line requirements (dedicated packaging, labeling, batch traceability)

In addition to the processes carried out directly in-house, we can complete the component with further operations internally or through a network of long-standing and qualified partners, including:

  • cold forming
  • stamping
  • milling
  • galvanic treatments and top coat
  • threading

This way, the customer receives a finished component, ready to be integrated into their assembly process.
