As an efficient partner for your success, HEWI offers broad-based expertise along the whole route to your product, from the initial development through to series production.

Your vision: From the design to the series product
• Starting with a model or a drawing
• Transfer into our 3D system – Siemens NX / CATIA
• Design of the product as an economic injection moulding
• Rapid prototyping
• Material selection and testing, strength calculations
• Working through requirements specifications – preparation of performance specifications
• Design FMEA

Your requirements: Comprehensive project planning
• Definition of all specific characteristics, requirements and quality objectives
• Preparation of a production plan: Logistics from raw material through to delivery
• Advance quality planning, process FMEA, test & inspection planning
• Definition of all resources, supplies and auxiliaries required
• Purchasing, installation, enabling, training, process validation • Comprehensive project management: Customer requirements, scheduled dates/deadlines, costs

Injection moulds
• Fill analysis with Mold Flow: analysis of weld lines and stresses
• Selection of the ideal mould concept
• Thermal analysis of the product: distortion and dimensional stability
• Mould design in 2D and 3D
• Definition of the required process monitoring: sensors and scanning systems such as HB-Therm Flow or Kistler pressure sensors • Mould production in Germany or with worldwide partners • In-house mouldmaking
From the preliminary sample through to series production
• Product support from the first-off tool parts until handover to series production: tests, samples, changes, assembly trials, automation
• Verification of process capability
• Comprehensive testing options due to in-house laboratory and measurement & test room
• Revision of the process FMEA: Feedback to the design phase
• Clearing and start of series production: Presentation of the initial samples with test reports
