Solder Paste Screw Valve High Precision Liquid Dispensing Control Valve Rotating Tip Collar

High Precision Solder Paste Screw Valve with Rotating Tip Collar Option Liquid Dispensing Control Valve for SMT PCB Assembly

Product Introduction

In the high-stakes environment of Surface Mount Technology (SMT) and semiconductor manufacturing, precise solder paste application is the foundation of reliable electronic assemblies. The HS-2000S and HS-2000R Solder Paste Screw Valves are state-of-the-art, positive displacement dispensing solutions engineered specifically to handle the abrasive nature of metal-filled solder pastes. Utilizing a precision screw auger mechanism, these valves deliver consistent, pulsation-free volumetric metering that eliminates the defects associated with traditional time-pressure systems. Whether you require the standard HS-2000S or the advanced HS-2000R, this series ensures flawless dot and line dispensing for high-yield production lines.

The following is an introduction to the specific situation of Dispensing Valve:

product description:
Dispensing Valve is a professional liquid dispensing control valve equipment.
It can accurately apply various liquid materials (such as glue, ink, solder paste, etc.) to designated locations.

Main functions and features:
Precise control: Through precise electromagnetic or pneumatic control systems, micro-amount, high-speed dispensing can be achieved.
Strong flexibility: applicable to liquid materials of different viscosities and flow rates, with wide compatibility.
Automation: Integrated with automated production lines to achieve full automation of the dispensing process.
High repeatability: The volume and position of each dispensing are highly consistent, ensuring stable product quality.
Good durability: Using industrial-grade parts and materials, it has a long service life.
Easy to maintain: simple structure, convenient daily maintenance and debugging operations.

working principle:
The liquid material is transported from the barrel to the valve body of the Dispensing Valve.
The electromagnetic or pneumatic drive system accurately controls the opening and closing time and strength of the valve to achieve the required dispensing amount and shape.
After dispensing is completed, the valve is closed and the liquid material automatically flows back to the barrel.

Application scenarios:
It is widely used in various processes of electronic product manufacturing, such as SMT patches, circuit assembly, etc.
Used for dispensing and coating precision electronic components and PCB boards, such as thermal conductive glue, sealant, etc.
It can also be used in production processes that require precise dispensing in food, medical and other industries.

Specification

Versatile Application Scenarios

The HS-2000S and HS-2000R are indispensable for high-reliability electronic manufacturing:
