High precision and automated production — around the clock

Micro-milling is one of our core competencies, and we therefore possess the necessary technology and experienced specialists. This enables us to manufacture micro components with complex geometries, thin wall thicknesses, and tight tolerances — often with requirements for extensive inspection and documented quality assurance. By integrating micro milling with automated production and robotics, we ensure efficient operations and high repeatability — 24/7.

Our key competencies

Experts in micro milling: Focus and specialization over decades
Tolerances: <5 µm
Complex geometries: Fine details, thin walls, and high precision
Automated production: 24/7 operation for efficiency and consistent quality

Precise fixturing of complex parts

Fixturing micro-milled components demands high standards for the fixturing method to maintain tight reference chains and geometric specifications. At Mekoprint, we have developed specialized fixturing solutions that enable secure and stable clamping of very small and complex parts.

Optimal fixturing ensures:

High repeatability
No deformation
Minimal manual handling

Finish machining in a single setup

With the right techniques, many micro-milled components can be finished in a single setup. This ensures high precision and lower costs—without compromising on quality. At Mekoprint, we are happy to review your part design and advise on potential modifications that can add significant value to your project.

Eliminating a process step improves:

Lead time
Total cost
Tolerances and process variation

Micro milling for less complex parts

Micro milling is not limited to components with exceptionally high demands. By combining high-speed milling with automation, we offer competitive production where micro milling provides advantages in terms of increased efficiency, precision, and quality.

When production is transferred to dedicated equipment for small components, a significant improvement is often observed in both consistency and level of detail.

Materials for micro-milled components

We offer micro-milled components in both metals and technical plastics. We deliver parts in easily machinable metals such as brass and aluminum, as well as more demanding materials like Mu-Metal. Within technical plastics, we have extensive experience with highly complex components made from materials including PEEK and PTFE. To ensure high and consistent quality, we use selected material suppliers. Materials used include:

Metals

Aluminum
Stainless steel
Brass
Nickel-iron alloys

Plastics

Vespel®

- Mechanical properties: Aluminium alloys cover a wide range — from easily formable variants to high-strength alloys with excellent mechanical characteristics. This provides great design freedom and the ability to meet both functional and machining requirements.
- Low weight and economy: The low weight combined with good machinability of some alloys makes aluminium an attractive alternative to steel and stainless steel — especially in applications where weight optimization and machining costs are critical.
- Surface treatment: Many aluminium alloys can be surface treated to improve properties such as corrosion resistance, electrical conductivity, solderability, and aesthetics. These treatment options offer great flexibility for the final application.
- Corrosion resistance: Corrosion resistance depends on the alloy’s chemical composition. Many easily machinable aluminium alloys require surface treatment if high durability is needed in demanding environments.
- Thermal conductor: Aluminium has excellent thermal properties and can be used for efficient heat dissipation. This allows, for example, the integration of cooling fins directly into the component design — an advantage in electronics, motor control, and sensor technology.
- Thermal stability: PEEK withstands very high operating temperatures while retaining its mechanical properties, making it particularly suitable for applications with thermal stress.
- Chemical resistance: The material is resistant to a wide range of aggressive chemicals, making it well-suited for use in demanding chemical and industrial environments.
- Strength and durability: As a lightweight material with high mechanical strength, PEEK is ideal for precision components where the combination of low weight and robustness is critical.
- Dimensional stability: PEEK has both a low coefficient of thermal expansion and minimal moisture absorption compared to other plastics. This makes the material especially suitable for applications exposed to varying temperatures and humidity levels, where high dimensional stability is essential.
- Material variants: PEEK is available in filled and reinforced versions, which improve wear resistance, electrical conductivity, strength, and coefficient of expansion depending on the requirements of the specific application.
- Medical Grade PEEK: PEEK is available in grades approved for medical device applications and is selected based on the specific application needs.
- Chemical resistance: PTFE is extremely resistant to almost all chemicals and is often used in aggressive or corrosive environments where other materials degrade.
- Temperature resistance: The material can be used at high temperatures, making it suitable for thermally stressed applications.
- Low friction: With one of the lowest coefficients of friction among plastics, PTFE is ideal for sliding and sealing elements where minimal wear and smooth movement are desired.
- Electrical insulation: PTFE is an excellent electrical insulator and is used in electronics and other applications.
- Typical applications: PTFE is widely used in the chemical industry, medical devices, electronics, as well as in pumps and valves where the material’s unique properties are advantageous.
- Thermal and mechanical stability: Vespel retains its properties at very high temperatures and under significant mechanical stress, making it suitable for use in critical and high-temperature environments.
- Low friction and high wear resistance: The material has low friction and high wear resistance, making it ideal for moving components requiring long service life and operational reliability.
- Dimensional stability: Even under extreme conditions, Vespel remains dimensionally stable and precise — a crucial characteristic for precision applications with tight tolerances.
- Typical applications: Vespel is commonly used for precision bearings, bushings, insulators, and other components where mechanical robustness and heat resistance are essential.
- Industries: The material is employed in demanding industries such as aerospace, automotive, and advanced electronics, where conventional plastics are insufficient.

Surface Treatment

We assist you in selecting the appropriate surface treatment to give your micro components the desired functional properties—such as improved corrosion resistance, solderability, or wear resistance. Treatments are performed either in-house or by carefully selected partners. Because micro components require special care, we ensure a precise and reliable process in close collaboration with you.

Typical surface treatments

Nickel: Used for corrosion protection or as a base layer for subsequent coatings.
Gold: High electrical conductivity, low contact resistance, and good corrosion resistance.
Anodizing: Increases wear resistance and corrosion protection on aluminum. Can also serve as an electrically insulating or decorative surface.
DLC (Diamond-Like Carbon): Low friction and high wear resistance. Ideal for moving micro components.
Tin: Used for solderable solutions on otherwise non-solderable materials—for example, in milled EMC/EMI components that require machine soldering onto printed circuit boards (PCBs).

Quality assurance and measurement technology

Precision is no accident! We inspect over 2 million parts each month using visual inspection, optical 2D/3D measurement, and mechanical measuring instruments—all of which can be performed in temperature-controlled environments. Our measurement methods are tailored to each specific task to ensure that agreed specifications are met.

We offer:

Optical 2D/3D measurement
Visual inspection
Various mechanical measurement methods
Quality documentation as required

Climate-Controlled Production

Optimal production conditions for precise components

Temperature variations can affect precision, especially during multi-sided machining. Therefore, at Mekoprint, we have designed our micro-milling processes to eliminate this influence. The micro-milling machines operate in a stable, temperature-controlled production environment and are equipped with multiple temperature-stabilizing features.
