Automated dispensing of polyurethane (PU) is often superior to manual silicone dispensing in quality and costs. Most Asian manufacturers of electronic components for solar inverters use manual dispensing techniques for potting or filling (e.g., regulators, transformers or PCBs with silicone). Shifting to polyurethane as the dispensing material, however, results in improved properties and lower production costs for the manufacturer.
When combined with a precisely defined mix ratio and exact metering of the dispensing quantity, these advantages develop their full potential. Therefore, using an automatic dispensing machine significantly increases production reliability, quality and productivity. Return on investment is almost immediate.
