Plastics
Monitor temperature across plastic processing, from blown film extrusion and rotational moulding to thermoforming, to ensure consistent quality and prevent defects.
Case Studies & factoids
Solutions that worked
Blown Film Extrusion
- Molten mass pushed through a ring nozzle, pulled vertically, and blown into a film tube
- Air cools the tube both inside and out during the process
- From the moment the melt exits the nozzle, temperature must be measured at multiple points along the tube
- Ensures the characteristics and quality of the finished film
- Process temperature: 195°C to 220°C
Rotational Moulding
- Negative mould filled with powdered or liquid PE or PP, sealed, heated to max 320°C, and rotated biaxially
- Material builds up layer by layer against the mould wall
- Mould cooled in a chamber before the part is removed
- Upon opening, the product is thermally tested — enabling immediate process adjustments if needed
- Process temperature: up to 320°C
Thermoforming
- Thermoplastic polymer sheets are heated on both sides until fully melted, then vacuum-formed into a tempered mould
- Even temperature distribution prevents local burning and crack formation
- Thermal imagers map the temperature regime of equipment; pyrometers monitor defined measurement points during production
- Part is transported only after it has cooled and reached dimensional stability
- Critical for advanced materials such as continuous fibre-reinforced thermoplastics used in automotive engineering
- Process temperature: 110°C to 230°C
