The plastics industry faces significant challenges concerning moisture control. Airborne moisture poses risks ranging from condensation on molds to moisture absorption by plastic granules.
Impact of Mold Temperature
Injection and blow molding operations rely on thermoplastics heated to achieve plasticity and shaped using molds. Maintaining a cold surface on the mold, often with chilled water, accelerates component forming and boosts production volumes. However, low mold temperatures can lead to condensation, resulting in watermarks on products and corrosion on molds and guide pins.
Addressing Sweating with Dehumidifiers
Solving the issue of sweating, or condensation, typically involves increasing mold surface temperature. Yet, this approach prolongs cycle times and reduces output. Incorporating a dehumidifier allows maintaining mold temperatures as low as 5°C without sweating, enhancing production efficiency.
Enhancing Production Efficiency
Lower mold temperatures facilitate quicker cycle times, leading to production output increases of over 30%. Regardless of external conditions, this efficiency boost ensures consistent productivity.
Optimizing Raw Material Storage
Proper storage of raw materials, such as plastic granules in silos, requires protection against moisture damage. Dry air, facilitated by a Seibu Giken DST dehumidifier, prevents mold formation and product sticking in pneumatic systems along the production line.
Preserving Mold Integrity
Dry air proves beneficial in mold storage by preventing corrosion, eliminating the need for frequent greasing. Maintaining relative humidity below 50% safeguards molds, ensuring their longevity and optimal performance
Conclusion
In conclusion, implementing moisture control solutions, including dehumidifiers, proves indispensable for enhancing efficiency, preserving equipment integrity, and ensuring consistent quality in the plastics industry.
