PT100 PUR Jetting Valve HS PF PUR30CC Hot Melt Dispensing Valve for SMT FPC PCB Assembly

PT100 PUR Jetting Valve HS PF PUR30CC High Precision Non Contact Dispensing Valve for SMT FPC PCB Electronic Assembly Hot Melt Polyurethane Adhesive Jet Dispensing Equipment

Product Introduction

The PUR Jetting Valve HS‑PF‑PUR30CC is a non‑contact high‑speed hot‑melt jet dispensing valve built for precision industrial automation. Equipped with PT100 temperature sensing module, this PUR jetting valve delivers stable heating for PUR hot‑melt glue, eliminating contact damage to workpieces during dispensing. Designed for 30cc glue cartridge, it supports ultra‑fine dot and line jetting without touching substrates. It can integrate seamlessly with most motion platforms, widely deployed for SMT, FPC and PCB precision assembly processes. As a core dispensing component, it solves common pain points such as inconsistent glue output, workpiece scratching and frequent glue blockage in traditional contact dispensing systems.

It has the following main features and functions:

1. High-precision jetting: PUR Jetting Valve uses advanced jetting technology to control the amount, speed and position of glue injection in a very precise manner. This accuracy makes it suitable for applications requiring high-precision glue application, such as fixing and sealing precision components.
2. Adjustability and programmability: The equipment has adjustable spraying parameters, such as glue spraying pressure, glue spraying time and glue spraying mode. This enables operators to fine-tune and optimize based on specific application needs. Some PUR Jetting Valve also have programmable functions, which can preset multiple glue spraying modes and paths to adapt to different process requirements.
3. Efficient production: PUR Jetting Valve has fast glue spray speed and response time to increase production efficiency. It is suitable for mass production environments, can quickly and accurately complete the glue coating task, and improve the production capacity and efficiency of the production line.
4. Strong adaptability: PUR Jetting Valve is suitable for glue materials with a variety of viscosities and fluidities, including polyurethane glue, epoxy glue, silicone glue, etc. The flexibility of the nozzle and valve design allows it to be adapted to different glue properties and application needs.
5. Self-cleaning function: Some advanced PUR Jetting Valve have a self-cleaning function, which can remove residual glue in the nozzle through cleaning fluid or gas flushing, reducing clogging and maintenance work.

Principle & Control

30CC PUR Jetting Valve

1. The PUR injection valve consists of a drum heating module, a pressurized cap module, a nozzle heating module, a flow path module, a valve body module and a heat dissipation module.
2. The barrel heating module carries the barrel as well as the one-stage heating with controllable temperature. The initial heating of the gel is completed.
3. The pressurized cap module seals and pressurizes the drum and controls the output pressure through the controller.
4. The heat dissipation module dissipates heat and reduces noise from the valve body.
5. The piezoelectric injection valve adopts a modular design, the part in contact with the gel is designed as the runner module, and the part not in contact with the gel is designed as the valve body module.
6. The flow path module can be changed to meet the dispensing requirements in different applications.
7. Nozzle diameters in series (from 40µm to 500µm).
8. The nozzles are categorized into flat jet type, needle type, and extension type.
9. Runner modules need to be cleaned regularly in an ultrasonic cleaner. Seals must not be immersed in organic solvents. Special tools are required to clean the nozzles to prevent damage to the nozzles.

Jet Valve Controller

1. The touch screen controls the piezoelectric injection valve and dispensing system, supports MES communication, powerful, safe and reliable.
2. The touch screen adopts graphic control mode, the components of dispensing system and the control display function are displayed graphically, which is concise and intuitive.
3. Nozzle heating device: The nozzle is required to be heated to a suitable temperature before dispensing. The heating device adopts one-stage heating mode.
4. Heating at the nozzle maintains the constant temperature of the gel to meet the best performance of the gel. The best performance of the colloid.

Nozzle and barrel heating

1. The nozzle is required to be heated to a suitable temperature before dispensing. The heating device adopts two-stage heating mode.
2. Heating at the nozzle maintains the constant temperature of the gel to meet the best performance of the gel. The best performance of the colloid.
