How to Choose the Right Dispensing Needle

Choose a Needle Gauge for Your Application

You need to pick a needle gauge that fits your job. Knowing about gauge sizes helps you choose the right needle. The gauge changes the inside size, which controls how glue or fluid moves. Bigger gauge numbers mean thinner needles. This changes the outside and inside sizes and the wall thickness.

When you pick a gauge, think about these things:

• How thick the fluid is

• How fast you want it to flow

• What material you are using

If your fluid is thin, use a small diameter needle. This gives you better control and more precise flow. If your fluid is thick, use a bigger diameter needle. This lets it flow faster and stops clogs. Picking the right gauge helps you get steady glue output and waste less material.

Your job needs also matter. Small jobs or micro-bonding need small needles for careful drops. Filling gaps or bonding big parts works best with bigger openings that give more fluid quickly. You must match the gauge to your job to get the best results.

Tip: Always check how thick your fluid is and how fast you need it to flow before picking a needle gauge. This helps you get the right needle for your work.

Selecting Tip Style and Length

Tip shapes are important for accurate dispensing. You can pick blunt tips, angled tips, or bent tips. Each style works for different jobs. For electronics, a 90° bent stainless steel tip with a 30 gauge and 0.5-inch length is good for careful drops.

Needle length helps you reach different spots. Long needles help you get to hard places. Short needles give you better control in tight spaces. The gauge also affects flow and accuracy. Small gauge needles are best for slow flow and careful work. Big gauge needles let fluid move faster.

Pick tip shapes based on your job needs. Contriu has blunt and angled tips. You can pick the length that fits your job. You can get custom lengths if you need special sizes.

Note: The right tip shape and length help you be more accurate and make your work easier.

Matching Needle to Fluid and Task

You must match the needle to the fluid and job. This helps you avoid clogs and problems. The fluid’s chemistry, needle material, hole size, and tip shape all matter.

Match the hole size to the fluid’s thickness and particle size. For filled epoxy, thermal paste, and silicone, use 14-18G with a tapered tip. Solder paste needs a needle hole at least five times bigger than the biggest powder particle, usually 18-22G. Coarse Type 3 paste works best with a 300µm hole. Thin glue, ink, or flux can be used with 22-27G.

The inside of a blunt needle is smooth. This stops fluid from speeding up at the tip. When the inside gets smaller and the fluid gets thicker, you need more pressure to keep it moving. Fluids with particles can block a small hole. You must pick the right hole size and tip shape for the fluid’s thickness and particle size.

Manufacturers give advice for matching fluids. For thin fluids, use a small general tip for better control. For solvents, a PTFE-coated tip stops fluid from sticking and helps accuracy. Thin glue needs PTFE-lined tips because it dries fast. For thick fluids, SmoothFlow tapered tips help flow and let you use less pressure.

Tip: Always check the fluid’s properties and your job needs before picking a needle. This helps you get the best flow and results.

You can pick the right needle by thinking about gauge, tip shape, length, and fluid match. Contriu’s product details help you choose the best needle for your job. You get smooth flow, accurate drops, and good results every time.
