The dispensing needle is able to determine the quality of dispensing gel, which kind of dispensing needle to choose has a great relationship with the industry. For example, flat-mouth brush needle is generally used for industrial gluing. Like the brush, it can be used for gluing, while machine gluing is more uniform. If stainless steel needle is used, the gluing effect is not as good as flat-mouth brush needle.
