When buying compounds for your plastics processing business, you have many options. Selecting a compound with the lowest cost per round could make sense, but doing so has a lot of disadvantages. A very cheap cost per round is usually a sign of poor quality. It can make it harder to clean your equipment, increase your scrap rate, and demand more material to complete the task. Furthermore, inferior products can not remove the contamination, regardless of the amount used. Compared to a high-quality compound, the sum of these considerations leads to a higher cost per purge.
Rarely do significant research and development efforts using cutting-edge materials technologies result in low-quality purging chemicals. Furthermore, businesses that market inferior cleansing compounds lack competent sales representatives and insufficient technical support. When selecting a drug, it’s crucial to understand the distinctions between high-quality and low-quality chemicals. The following are essential components to search for in a purging compound:
- Designed to Keep Injection Molding Equipment and Extruders Clean
Businesses may attempt to combine handmade mixtures, virgin resin, laundry detergent, and regrind together with chemicals. A high-quality purging compound is a plastic resin compound specially designed to clean all plastic machinery, including extruders, blow molders, and injection molding machines when the resin or color changes. Furthermore, it can eliminate carbon or color from downstream equipment and tools, such as extrusion dies and hot runners.
- Material Selection for the Items
Material affinity was not taken into consideration when producing inferior cleaning agents, according to Procurenet. Use only purging substances compatible with the substance you’re getting rid of. That guarantees thorough purges, reduces residue accumulation, and prevents contamination buildup in your machines.
- Minimal Residue Features
For effective and rapid purging, a high-quality purging substance should leave minimal residue behind. Use a grade intended for residue-sensitive applications or low-temperature resins if residue in your machines is causing frequent problems. When attempting to reduce purging chemical residue, you can use these grades as a chaser in conjunction with other purging grades because they leave less residue behind.
- There are various product grades available.
Compounds are not universal, and your procedure determines which compound you use. A high-quality compound should provide product-grade options for various resin kinds, such as commodity, engineering, and super-engineering materials. Subpar compounds frequently have restricted grade options and may be glass-filled or high-heat alternatives.
- Sealing Thermally Stable
During machine shutdowns, it is vital to seal the screw and barrel with an adequate, thermally stable purging compound. It guarantees that your purging compound displaces any leftover heat-sensitive resin from your previous production cycle.
Sealing the screw and barrel prevents oxygen from entering the barrel and is commonly done when closing down for the weekend or before extended holidays. Heat and oxygen combine to form a situation that promotes deterioration and carbonization, according to Procurenet. Residual polymer degradation can cause machine startup delays and material waste. Choose a compound carefully; don’t compromise on quality for price. A superior product will increase productivity, decrease downtime, and increase your company’s profitability.
