In high-end fields such as precision industrial manufacturing, electronic packaging and medical equipment, precise dispensing technology is a key link to ensure product quality. As an important part of the dispensing equipment in direct contact with the glue-the dispensing needle, its choice has a vital impact on the stability and accuracy of the dispensing process. Among the many materials of dispensing needles, stainless steel dispensing needles are favored for their excellent performance. This article will delve into the applicability of stainless steel dispensing needles to help users better understand and choose the right dispensing solution.


First of all, we need to understand what is a stainless steel dispensing needle. This type of needle is made of stainless steel material, with corrosion resistance, wear resistance and high strength characteristics. They are commonly used in dispensing applications that require high corrosion resistance and high precision, such as UV glue, epoxy resin, solder paste, grease and other liquid materials of different viscosity and composition.


Next, let us analyze the advantages of stainless steel dispensing needles:

1. Corrosion resistance: stainless steel material makes it still maintain stability in harsh environments, and has good resistance to corrosive fluids such as strong acids and alkalis, and is suitable for long-term use in special environments.

2. Strong wear resistance: stainless steel needles have high hardness, even if they are used for high-frequency dispensing operations for a long time, they are not easy to wear, ensuring a long service life and consistent dispensing effect.

3. High precision: Due to its excellent physical properties, stainless steel needles can achieve very fine dimensional tolerances, providing the possibility for micro-dispensing, ensuring the accuracy and repeatability of dispensing.

4. Temperature stability: Stainless steel needles can maintain performance in a wide temperature range, suitable for applications that require heating or cooling processes.


However, despite the advantages of stainless steel dispensing needles, the following aspects still need to be considered in specific applications:


1. Needle size: According to different dispensing needs, it is very important to choose the appropriate needle inner diameter and outer diameter. Too small needles may cause clogging, too large will affect the dispensing accuracy.

2. Needle shape: According to different applications, the shape of the needle also has a variety of designs such as straight and oblique to adapt to different dispensing angles and positions.

3. Fluid properties: Different fluids have different chemical properties and viscosities, so it is necessary to select suitable needle materials and specifications according to the actual type of glue used.

4. Glue dispensing equipment: Stainless steel needles need to be used in conjunction with glue dispensing equipment, so it is necessary to ensure that the selected needles are compatible with the equipment to avoid damage to the equipment or affect efficiency.

How to choose the right dispensing needle for the dispensing machine?

The glue dispenser is also called glue coating machine, glue dripping machine, glue filling machine, etc. It is an automatic machine that specially controls the fluid and drips and coats the fluid on the surface of the product or inside the product. It can realize three-dimensional and four-dimensional path glue dispensing, precise positioning, precise glue control, no wire drawing, no glue leakage and no glue dripping. The glue dispenser is mainly used for the precise point, injection, coating and drip of glue, paint and other liquids in the product process to the precise position of each product. It can be used to achieve dot, line, circle or arc. How to choose the right dispensing needle for the dispensing machine? The following guidelines are for reference: 1. Small point: small size dispensing needle, low pressure, short time. 2. Big point: large dispensing needle, greater pressure, longer time. 3. thick glue: oblique needle, large pressure, according to the need to set the time. 4. Aqueous liquid: small size needle, less pressure, set time as needed Fluids requiring special settings: 1. Instant glue: use safety piston and Teflon-lined metal needle for water-based instant glue, use tapered needle for thick instant glue, and use PP needle if flexibility is required. 2.UV glue: use amber syringe, white piston and inclined needle (can shield UV). 3. Anaerobic glue: use 10CC syringe and white PE universal piston. 4. Sealant and paste fluid: If the use of white piston rebound serious, please switch to the safety type, the use of oblique needle. Dongguan Xiangzhirui Electronics Co., Ltd. is located in Humen Town, Dongguan City, which is known as the "World Factory", at the head of the "Four Tigers" in Guangdong on the east bank of the Pearl River Estuary.
