The decision between using a liquid purging compound or a pelleted one to clean the PET preform system is an important matter to consider in the industry. Both methods have their advantages, so it is crucial to evaluate several factors before making a decision.
Pellet purge – Widely used in the industry, Easy to handle, High compatibility.
Pellet purges were the first to be successfully used for cleaning Husky machines. Although generally limited to barrel cleaning, they are efficient.
They are often compatible with a wide variety of processes and materials.
However, if you opt for pellet purge, you will need to check the manufacturer’s recommended temperature range. The reason behind this is that these formulations use thermoplastics as a vehicle for the purging components.
Depending on which material you want to change, you will have to check its working temperature and make sure that it matches the one of the pellet compound. Otherwise, the mixture will not perform properly and will cause problems inside the machine.
Liquid Purging Compound – Fast, Efficient, Safe and Economical
Husky has recognized and accepted the use of certain liquid purges to clean its preform injection molding equipment for several years. The liquid purge, which is dosed as an additive directly into the mix, can be used to clean the preform injection molding equipment without stopping the machine at any time. This means that the cleaning process can be carried out faster and more efficiently, saving time and increasing productivity.
In addition, the use of a liquid purging compound can be up to three times cheaper, resulting in considerable savings on operating costs. Also, liquid purges require a dosing device similar to the one used in the industry for liquid dyes, making their implementation in existing equipment easier.
Another important advantage is safety for technicians. By not requiring a complete machine shutdown, the risk of accidents and injuries during the cleaning process is reduced. This is especially relevant in production environments where safety is a priority.
In summary, the decision between using a liquid purging compound or a pelleted one to clean your PET preform system should be based on a careful evaluation of cost, efficiency, safety, and specific cleaning requirements.
Both methods have their advantages, so it is important to take into account the company’s needs before making an informed decision.
