Plastics Manufacturing
Injection Moulding, thermo forming and polymer storage without condensation is possible!
Moisture in the air can cause havoc in the manufacture of plastics. Condensation will begin to form on the moulds and plastic granules will begin to absorb the moisture.
There is no external factor as detrimental to plastics processing than moisture.
HOW DOES MOISTURE AFFECT PLASTIC?
Moisture causes issues with stored hygroscopic compounds
Condensation forms on plastic moulds
Condensation absorbs into plastic granules
Bubbles form in finished product
Clarity and crystalline structure of end product is of poor quality
DEHUMIDIFIERS DESIGNED FOR THE PLASTICS MANUFACTURING INDUSTRY
A Desiccant Dehumidifier – Mould Dehumidification System
A Desiccant Dehumidifier used in the plastics industry is the ideal solution. A desiccant dehumidifier can achieve a consistent low mould temperature of 5° C or lower. It will remove the moisture from the air, eliminating condensation which allows for speedier cycle times leading to greater production rates. It also protects vital equipment. A dehumidification system safeguards the equipment against corrosion by keeping the moisture at bay.
Improved Plastic Products
A mould dehumidification system will eliminate the issue of shock cracks forming and it will improve the clarity and crystalline structure of the end product. Without water droplets forming on the mould, the surface finish of the product is highly improved.
Improved Raw Material Storage
A desiccant dehumidifier is also the optimal choice for the storage of raw materials. It is designed to eliminate moisture in the raw material before processing. Dehumidifiers are the ideal choice for storing any hygroscopic material.
Plastic granules, generally stored in silos can absorb moisture, so adding dry air to the storage space removes this moisture. The Dehumidifier does this by forcing ambient air through a desiccant wheel blowing dry air over the plastic granules.
Improved Mould Storage
Dry air can also be used when storing moulds. No need to put in time and effort in greasing the moulds - they are kept free from corrosion when the relative humidity is below 50%.
Avoiding moisture in the pneumatic system is also highly beneficial. Adding dry air will stop mould formation and stop the granules from sticking together.
No Effects from Weather or Changing Seasons
Ambient air (unconditioned air – air in its natural state) is unfavourable to many of the processes within plastics manufacture and has a direct effect on the end product. A desiccant dehumidifier is unaffected by external air temperature and can maintain a consistent temperature in all seasons.

We also offer Rental Dehumidifiers. A great way to test the technology before investing or for temporary use during the more humid months when ambient air affects your products more severely. Visit our Dehumidifier Hire page to learn more - we have seen many industries benefit greatly from the temporary use of dehumidifiers.
INDUSTRIAL Dehumidifier HIRE
Is your plastics manufacturing business looking to test the technology before investing? Or does it suffer from seasonal changes? Either way, dehumidifier hire is a risk-free option. Humiscope has a large range of industrial and commercial dehumidifiers for long and short term rent.
