Tips for buying a dispenser:
First, before buying a dispenser, there are two things that need to be clarified:
1. Basic characteristics of the glue used:
1) What is the glue? One-component or two-component (AB glue)?
2) If it is two-component, what is the volume ratio of AB glue?
3) The viscosity and density of the glue?
4) How long does the glue begin to cure? Full cure time?
5) How is the glue packed?
2. Requirements to be achieved in the dispensing process:
1) What are the requirements for dispensing accuracy? How much glue does each product use?
2) Is glue used for potting? Paste? insulation? Moisture-proof? bit?
3) How to achieve the dispensing operation?
Second, the purchase tips for dispensers:
1. Glue: Single-component dispenser for common glue, dual-liquid dispenser for AB glue, PU glue dispenser for PU glue, and specific syringe for UV glue.
2. Dispensing process: ordinary dispensing uses a semi-automatic dispensing machine (such as foot control), and precise positioning of the scribe line uses a desktop, three-axis, circle drawing and other automated dispensing machine. The automatic function of the dispenser is actually a subsidiary function. The dispenser functions more to control the glue. Other functions can be realized by the automated robot.
3, work efficiency and environment: less products, do not pursue efficiency, use a manual glue gun; outdoor work, use a glue gun. Require precise control of the contest and use the machine. If automated dispensing is required, use an automated machine.
4. Cost: There are various dispensing solutions. Not all dispensing requires a machine, and not all automated dispensing must be attached to the dispensing machine. In terms of cost, if a certain glue needs to use a too expensive machine, you can consider replacing the glue. If the price of an automated dispenser is too high, consider moving the product instead of the dispensing head.
