First, in the purchase of dispenser before, we must first understand two things:
　　1. The basic characteristics of the glue used:
　　① What is the glue? One-component or two-component (AB glue)?
　　② If it is two-component, AB glue volume ratio is how much?
　　③ glue viscosity and density?
　　④ Glue about how long to start curing? Complete curing time?
　　⑤ glue how to package?
　　2. Dispensing process need to meet the requirements:
　　① dispensing accuracy requirements? How much glue each product?
　　② glue is used to potting? Paste? insulation? Moisture? bit?
　　③ requirements how to achieve dispensing operation?
　　Second, dispenser purchase tips:
　　1. Glue: One-component glue dispenser for general glue, double glue dispenser for AB glue, PU glue dispenser for PU glue, glue dispenser for special UV glue.
　　2. Dispensing process: The use of semi-automatic dispensing plastic dispenser (such as foot control), precise positioning of the scribe is selected desktop, three-axis, draw the circle and other functions with automatic dispenser. In fact, the automatic dispenser function is ancillary functions, glue dispenser play more role in the control of glue, other functions can be achieved by means of automated robots.
　　3.Work efficiency and environment: less product, not the pursuit of efficiency, the use of manual glue gun; outdoor work, the use of glue gun. Requires precise control of the contest, the use of machinery. Requires automatic dispensing, the use of automated machines with features.
　　4. Costs: There are a variety of dispensing options. Not all dispensers require the use of a machine, and not all automated dispensers must be attached to a dispenser. From the cost considerations, if a glue needs too high price machines, you can consider changing the glue. If the auto dispenser is too expensive, consider moving the product over the dispense head.
