Main technologies
We focus on high-precision CNC machining, work with any type of material and offer different production technologies such as: CNC machining, silicone moulds, injection moulding, 3D printing and sheet metal processing
Maximum precision for complex geometries in plastic and metal up to a minimum milling radius of R 0.15 mm – R 0.10 mm
Vacuum casting with silicone moulds is ideal for small quantities, different colours, finishes and material properties.
We manufacture injection moulded parts for small series production, entirely according to individual component requirements.
Fast and precise production using additive manufacturing offers a great deal of freedom in the design and utilisation of pre-series components.
We offer sheet metal processing from laser cutting and subsequent bending and post-processing
With our wide range of colour material finish options, components or mockups are given the appearance of a series product.
Key Advantage
• High Precision: Tolerance up to ±0.005mm
• Small Batch Friendly: 1 piece minimum order
• Fast Delivery: Short lead time for prototypes
• Full Inspection: CMM, KEYENCE, Mitutoyo equipment
• Strict Confidentiality: NDA signed for every project
• One-stop Service: Processing + surface treatment + assembly
