## 2. Other manufacturing technologies

For projects that require very specific mechanical properties or high-demand surface finishes.

| Technology | Description | Capacity | Tolerances | Best For | Key Benefit | More information |
| --- | --- | --- | --- | --- | --- | --- |
| Vacuum Casting (Silicone Molds) | The bridge technology between 3D printing and final injection moulding | Series of 10 to 50 units, for parts with maximum dimensions between 30 and 100 cm | Approximately ±0.5% (minimum deviation ±0.5 mm) from the nominal dimension, depending on the material shrinkage. | High aesthetic functional prototypes, casings with specific textures, transparent parts and over-molded (bimaterial). | Allows you to produce plastic parts in small batches replicating final injection-moulded properties (ABS, PC, rubbers) with minimal tooling investment. | fas fa-link |
| CNC Machining | We use machining centers to work on blocks of metallic material, technical plastics and other materials | From unique prototypes (1 unit) to medium series of 500 units | Up to ±0.01 mm (depending on the geometry and the material). | Final parts of high mechanical resistance, threads and critical adjustments. | Maximum structural resistance when using blocks of certified material, excellent surface finishes (Ra 0.8 to 3.2). | fas fa-link |
| Rapid Tooling | Rapid tooling utilizing aluminium or soft steel moulds to inject real production material. | From 100 to 10,000 units. | ±0.05 mm to ±0.1 mm, allowing fine adjustments before mass production. | Validation of materials and pre-series before the manufacture of the final injection mold. | Drastically reduces time-to-market and investment risk by detecting design errors in the final process at a lower cost than a steel mold for high productivity. | fas fa-link |
| Vacuum Forming | Ideal for large-surface enclosures, trays, and panels with constant wall thickness using extruded thermoplastic sheets. | From manual prototypes (1-10) to automatic industrial series (10,000+). | Moderate (±0.5 mm to ±1.0 mm), since the thickness of the wall varies according to the stretching of the sheet. | Packaging (blisters), vehicle interior panels, refrigerator casings and logistics trays. | Very economical tools compared to injection molding and the ability to manufacture large format pieces with a very light weight. | fas fa-link |
| Metal Pressing | Forming process that uses presses and dies to cut, perforate or bend metal sheets by means of pressure. | Large volumes, typically from 5,000 units up to millions. | ±0.05 mm to ±0.2 mm depending on the thickness of the sheet and the complexity of the bending. | For thin sheet metal parts with high repeatability (connectors, supports, clips and light structural components). | Extremely low unit cost in large volumes and high production speed with minimal waste of material. | fas fa-link |
| MIM (Metal Injection Molding) | Combining the geometric freedom of plastic injection moulding with the full strength of metal for small, intricate parts. | High production, generally higher than 5,000 units per year to amortize the equipment. | ±0.3% to ±0.5% of the nominal dimension (requires post-processing for more critical tolerances). | Parts with complex geometry and reduced size (watches, surgical tools, engine components). | Eliminates the need for complex machining in parts with intricate internal details, offering metal densities close to 98%. | fas fa-link |

💡 **Recommendation**: For volume pricing, we recommend requesting a **detailed quote**. Our team will analyse the best technology combination for your production run and apply the corresponding quantity discounts.

Precision of the parts

**CNC machining** allows for tolerances of one-hundredths of a millimeter (**down to ±0.01 mm**), ideal for bearing or thread fittings. **HP Multi Jet Fusion (MJF)** technology, on the other hand, offers industrial precision of approximately **±0.2 mm (per 100 mm)**, making it the more balanced option for complex functional parts.

Yes. At **Ineo**, **we integrate heat-sealed threaded inserts into MJF, SLS, and PU (vacuum cast) parts** to ensure durable mechanical connections. For small metric or high-performance threads, we recommend subsequent CNC machining of the printed part, especially if it is metallic.

**Orientation is a determining factor in the final quality of any 3D printed part**, affecting it differently depending on the technology:

**SLA**: Orientation defines where the necessary supports will be placed. Incorrect placement can leave marks on critical surfaces or affect transparency.

**SLS and MJF**: As powder bed technologies, they don't require supports, allowing for greater freedom. However, orientation affects dimensional accuracy along the Z-axis and the roughness of curved surfaces.

**FDM**: This is the most sensitive technology. Orientation determines the mechanical strength of the part (layer junctions are potential points of failure) and the definition of fine details.

At **Ineo**, **our technical team optimizes the orientation of each part during file preparation** to maximize accuracy and aesthetic finish. If your part has a critical face or a functional fit, we recommend indicating this when requesting your **detailed quote**.

Technical Surface Finishes

At Ineo, **we offer a wide range of surface finishes** designed to enhance both the aesthetics and optimize the mechanical and functional properties of your parts:

**1. Surface and Texture Finishes**

- **Sandblasting**: Ideal for homogenizing surfaces, removing manufacturing marks, and achieving a uniform matte texture, especially on technical parts.
- **Hydrographics**: An advanced solution for applying complex patterns such as carbon fiber, marble, or wood, radically transforming the visual appearance of the part.
- **Professional Painting**: We offer different levels of gloss and texture depending on the project's needs: gloss, satin, matte, or textured.

**2. Colour and Protection Treatments**

- **Dyeing**: A color impregnation process (usually black for technologies like MJF) that guarantees a uniform finish without altering the part's dimensions.
- **Staining**: A color impregnation process (usually black for technologies like MJF) that guarantees a uniform finish without altering the part's dimensions.
- **Metallization and Chrome Plating**: We apply coatings that provide a high-quality metallic finish, enhancing surface resistance and the premium aesthetics of the component.

**3. Customization and Technical Marking**

- **Laser Marking**: High-precision engraving of text, logos, and images directly onto the part. It is the preferred option for industrial traceability and permanent customization.
- **Pad Printing**: An ideal printing system for applying detailed graphics or logos to curved or irregular surfaces with high definition.

At Ineo, painting is not just an aesthetic process, but an additional layer of protection. **We apply technical paint adapted to each material to ensure a uniform color and durability**.

**Our painting options**:

- **Matte**: Eliminates reflections and conceals minor surface imperfections.
- **Satin**: The perfect balance between shine and understated elegance, widely used on electronic housings.
- **Gloss**: Ideal for high-visibility aesthetic parts or prototypes that simulate consumer products.
- **Textured**: Provides a tactile, rough finish that improves grip and offers a premium industrial appearance.

To ensure that the paint does not crack or peel (especially on materials like PA12 or resins), we perform a surface pretreatment using **sandblasting or technical sanding**. This increases the surface energy of the part and prepares it for the **application of a specific technical primer**, which acts as an adhesion bridge. This process allows the final lacquer to be permanently fixed, achieving a durable and high-quality finish.

Delivery times and profitability

Yes. **From our main technical facility located in the** **Barcelona industrial area (Spain)**, we operate as a highly agile manufacturing and nearshoring hub serving clients across Europe and globally.

Being strategically situated in **one of Europe’s primary industrial corridors** allows us to guarantee reliable, **fast transit times for international shipments**. For instance, standard express courier deliveries to Central European destinations (such as Germany, France, or the UK) typically take just 24 to 48 hours once production is complete.

Furthermore, all our project management, design reviews (DFM), and technical consultations are conducted seamlessly in English and German. Distance is never a barrier; we bridge it with strict quality controls, transparent tracking, digital engineering workflow solutions, and international shipping protocols that ensure your custom components arrive safely at your facility, anywhere in the world.

The **lead time** varies depending on the technical complexity and the required finish, differing mainly due to the **technology used**:

- **3D Printing (Additive Manufacturing)**: This is our fastest solution. We can deliver runs of hundreds of parts or custom tooling within **3 to 5 business days**, thanks to the elimination of molds and prior preparation processes.
- **Other Technologies (Injection Molding, Vacuum Casting, etc.):** For these processes that require the creation of specific molds or tooling, lead times are usually **1 to 4 weeks**, depending on the geometry and post-processing requirements (such as cleanroom curing or special surface finishes).

Warning: Orders outside Spain require extended lead times. Additional delivery time varies by destination country and local logistics/customs factors. For precise international delivery estimates, contact our customer service team.

**Note**: In all cases, **we optimize our workflows to offer customized solutions** with minimal lead times.

Generally, for parts of medium complexity, **digital manufacturing is more cost-effective up to 3,000–5,000 units**. At this point, the cost of the traditional injection mold begins to be recouped. INEO's advantage lies in eliminating the initial capital expenditure (CAPEX) and delivery in days, not months. Part size and material volumen are key factors.

Certifications

Yes, **our company is ISO 9001 certified**. This international standard guarantees that all our manufacturing processes, from design reception to final delivery, meet the strictest quality controls and continuous improvement standards.
