Linde PLASTINUM - CO2 Foam Injection Moulding
Bringing simplicity and flexibility to physical foaming - with robust carbon dioxide solutions from Linde that work on standard injection molding machines. Best of Both Worlds - with End-to-End Offering: Our PLASTINUM® Foam Injection Molding technology combines the benefits of simple chemical foaming with the efficiency gains of physical foaming. We developed this innovative solution in collaboration with Kunststoff-Institut Lüdenscheid (KIMW). Depending on your volume requirements, the carbon dioxide (CO2) gas can be supplied from cylinder bundles or a bulk tank.
If bulk supply is preferred, we can provide a PRESUS® C boosting pump, pressurizing the CO2 to the required impregnation pressure. PRESUS C is an energy-efficient pressure-boosting unit ideal for CO2-based molding processes. Our entire gas supply and pressure-boosting package has been engineered to capitalize on the physical properties of CO2 as a foaming agent for stable, predictable outcomes in foam injection molding.
- Ease of installation and operation - can be retrofitted to almost all machines regardless of the manufacturer
- Few or no modifications to existing machinery required
- Potential for sizeable density reductions of up to 50% (depending on polymer, wall thickness, geometry, required mechanical properties, mold technology), as a large amount of CO2 can be absorbed
- Significant drop in costs relative to alternative physical foaming solutions
- Increased production flexibility as several injection molding machines can be supplied simultaneously
- Higher return on capital investment as the same machine can be used for foamed and solid parts
- Our PLASTINUM Perfoamer system allows you to quickly and easily integrate physical foaming technology into existing injection molding installations.
- This ready-to-run kit consists of two main components:
- An autoclave vessel in which the plastic granulate is impregnated with high-pressure carbon dioxide
- A pressurized buffer tank in which the granulate is stored for processing
- Equipped with optional conveying systems, it can automatically supply one or more injection molding machines (depending on your throughput).
