Output Reference

Reference extrusion output: SJ35 is typically quoted around 8-10 kg/h, and SJ45 around 15-18 kg/h.

Line speed is calculated from tube gram weight, so the same kg/h output can convert to very different m/min or pcs/min. Jinxin calculates practical speed from the buyer's tube OD, ID, wall thickness, material density, cut length and collection method.

Recent sample reference: On SJ45 configurations, thicker LDPE dip tubes may convert to about 20 m/min, while lighter thin-wall PP dip tubes may calculate above 70 m/min. Final speed is confirmed after sample review and factory testing.

Output note: kg/h is the extrusion capacity; m/min is line speed; pcs/min also depends on cut length.

In-Line Cut-End Profiles

Many dip tube producers buy a separate notching or cutting machine to form V-notch, slanted or concave ends after extrusion. Jinxin's servo flying-knife forms the final end profile during extrusion - flat (square) cut, V-notch (custom angle), slanted cut, or concave cut - so tubes come off the line ready to assemble, with no secondary trimming step.

Comparison	Process
Separate cutting step after extrusion	Separate notching or cutting after the tube is extruded
In-line final cut profile during extrusion	Final cut-end profile formed during extrusion

Each profile is produced by its own dedicated cutter head, built to the buyer's specification. The V-notch angle is customizable. The required cut shape, V-angle and tube length must be confirmed before production and cannot be changed after the cutter head is made; additional profiles need additional heads, which can be quoted together.

Flat (square), V-notch, slanted and concave cut-end profiles formed in-line - no separate cutting machine required.

PLC controlled single screw extruder for small diameter PE and PP dip tube production

Main extrusion module

Precision Single Screw Extruder

The single screw extruder plasticizes PE (incl. LDPE) or PP pellets and delivers stable melt flow to the die head. For typical 3-10mm dip tube production, Jinxin configures SJ35 or SJ45 platforms so the screw output, melt residence time and temperature control match stable PE / PP small-tube production.

Detail	Reference
Motor	Siemens Beide inverter-duty motor.
Drive	Direct coupling design without belt transmission.
Inverter	ABB ACS580 for stable speed control.
Control	WECON PLC and touchscreen interface.
Screw	Nitrided steel screw configured for PE (incl. LDPE) / PP melt stability.
Heating	Multi-zone temperature control with SSR control.

Die head and tube entry for small diameter dip tube extrusion tooling

Tube forming tooling

Die Head And Tooling Set

The die head forms the thin-wall tube and must match the target OD, wall thickness and drawdown behavior. Tooling is configured for the buyer's sample rather than copied from a generic tube size.

Function	Why It Matters
Polished flow channel	Helps reduce melt stress and tube instability.
Matched core and sleeve	Controls OD, ID and wall thickness.
In-house adjustment	Allows correction during factory testing before shipment.
Size-specific tooling	Supports different tube sizes through matched tooling sets.

OD calibration

Vacuum Calibration And Cooling Tank

The vacuum tank stabilizes tube roundness and OD while the tube cools. For dip tubes, this is one of the main controls behind assembly fit and leakage prevention.

Detail	Reference
Construction	SUS304 stainless steel tank.
Alignment	3-axis adjustment for die-to-haul-off centering.
Vacuum	Water-pump vacuum system for stable negative pressure.
Tube path	Integrated pressure rollers help keep the tube immersed.
OD control	Supports +/-0.05mm OD stability target after configuration.

Air knife drying unit before haul off on dip tube extrusion line

Surface drying

Integrated Air-Knife Drying

The circular air-knife channel removes surface water before haul-off and cutting. This reduces traction slip and helps keep cut length and OD stability more consistent.

Function	Benefit
360 degree air wiping	Removes water around the tube surface.
Drier haul-off contact	Reduces micro-slippage in pulling rollers.
More stable cutting	Helps improve cut length repeatability.
Cleaner collection	Reduces residual water before winding or packing.

Haul off system for stable pulling of thin wall dip tubes

Synchronized pulling

Precision Haul-Off Options

The haul-off system synchronizes tube pulling with extrusion output. For typical 3-10mm thin-wall dip tubes, Jinxin usually configures a compact roller-type haul-off because the tube is small, light and does not require high pulling force. A precisely adjustable roller haul-off gives stable traction with a compact footprint. The key is fine roller gap and pressure control: too much pressure can mark or deform a thin tube, while too little pressure can cause slip, runout or length variation. Belt-type haul-off can be quoted when the tube material, softness or tolerance target requires a different pulling method.

Option	Best For
Adjustable roller haul-off	Typical 3-10mm thin-wall dip tubes, compact layout and stable pulling.
Fine roller gap / pressure control	Reduces slip, tube marking and deformation risk.
Belt-type haul-off	Quoted when tube softness, wall thickness or tolerance target requires it.
Synchronized speed control	Supports stable OD and repeatable cut length.

Servo flying knife cutter for in line dip tube cut end profiles

Cutting system

Delta Servo Cutting System

The servo flying-knife cuts each dip tube to length and forms the final end profile in-line. The cutter head can be customized to the required shape - flat (square), V-notch, slanted or concave.

Detail	Reference
Drive	Delta servo motor and driver.
Length control	Encoder-based repeatable cutting.
Cut profiles	Flat (square) cut, V-notch (custom angle), slanted cut or concave cut.
Interface	Touchscreen settings for length, counting and alarm.
Custom head	Quoted according to required cut geometry.

Tube collection

Horizontal Or Dual-Shaft Winder

Some dip tube production uses winding before later cutting or assembly. Jinxin configures the winding system according to tube softness, reel size and production flow.

Option	Purpose
Horizontal winder	Gentler collection for fine or soft tubes.
Dual-shaft winder	More continuous winding for standard production.
Magnetic powder clutch	Supports steady winding tension.
Traversing unit	Keeps tube layers neat on the reel.
Custom reel setup	Matched to packaging or downstream handling.

Cooling water support

Industrial Water Chiller

Stable cooling water helps keep the calibration process consistent during continuous production. The chiller reduces dependence on unstable civil water temperature.

Item	Reference
Type	Air-cooled or water-cooled unit according to factory conditions.
Role	Supports stable calibration and cooling temperature.
Benefit	Helps reduce OD drift caused by water temperature changes.

Applications

Lotion pump dip tubes used with bottle pump packaging

Lotion Pump Dip Tube Production

Lotion pump dip tubes need a stable interference fit inside the pump housing. LDPE is commonly used because it can bend inside the bottle while still holding shape during automated insertion.

Perfume pump dip tube for fine mist sprayer application

Perfume Pump Dip Tube Production

Perfume pump tubes are often narrow and thin-wall. They need clean cut ends, stable OD and sometimes V-notch or slanted cuts to match fine mist sprayer geometry.

PP aerosol valve dip tube for pressurized container application

Aerosol Valve Dip Tube Extrusion

Aerosol valve dip tubes often use PE or PP depending on stiffness, chemical resistance and valve design. Stable roundness and material consistency help the tube fit reliably in pressurized packaging.

Trigger sprayer dip tube for household cleaning bottle application

Trigger Sprayer Dip Tube Production

Trigger sprayer dip tubes for household and garden bottles may use larger diameters and wider tolerance windows than cosmetic pump tubes. Stable drying, haul-off and cutting still matter because surface moisture can cause traction slip and length variation.

Why Manufacturers And Procurement Leaders Choose Jinxin

What Our Clients Say

We run extrusion lines from multiple suppliers, but Jinxin's 360 degree air-knife was clearly the best moisture-removal design we had seen. We ended up ordering additional air-knife units from them to retrofit onto our existing production lines. It solved a residual-water problem that had been causing cut-quality issues for months.

Production Manager, Dip Tube Manufacturer, France

We needed V-cut dip tubes with a specific angle for our perfume pump assembly line. Jinxin built the custom cutter head exactly to our specification, and the cut quality has been consistent from day one. Every tube fits the pump fitting without rework.

FAQ

FAQ - Dip Tube Extrusion Line

01 PE (including LDPE) or PP - which material should a dip tube extrusion line process?

PE, especially LDPE, is common for lotion pump, perfume pump and many cosmetic dip tubes because it provides flexibility inside the bottle. PP is used when higher stiffness or chemical resistance is needed, such as some aerosol valve tube applications. Jinxin confirms the screw, temperature profile and tooling according to the buyer's material.

02 Is 3-10mm OD enough for my project, or what if I need 2mm or 12mm?

3-10mm covers most cosmetic pump, perfume pump, trigger sprayer and aerosol valve dip tubes - it is a typical application range, not the mechanical limit of the extruder. Within this range, changing tube OD requires a matching die tooling set (die and core) and calibration sleeve.

For diameters outside this range - finer tubes around 2mm or larger tubes around 12mm - Jinxin reviews the target size against tooling, cooling and haul-off capability. Smaller tubes are more sensitive to cooling stability and haul-off alignment. Send a sample or drawing and Jinxin can confirm feasibility and configuration.

03 Some suppliers advertise 300 m/min dip tube lines - is faster better for my project?

For dip tubes, no. A headline like "300 m/min" is line speed, not output. A thin dip tube weighs very little per meter, so high line speed mainly adds cooling-tank length, footprint and energy use, not tube quality. Those lines are built for one tube size in huge volumes. For multi-size cosmetic, perfume, pump and aerosol dip tubes, +/-0.05mm OD precision, clean cut ends and fast changeover matter far more than peak m/min.

04 Is laser or ultrasonic online measurement standard?

No. Laser or ultrasonic online diameter measurement is optional. It can be added when the buyer needs continuous OD monitoring, tighter QC records, higher automation or traceability. Standard OD control relies on die matching, vacuum calibration, stable cooling, synchronized haul-off and factory test-run verification.

05 Do I need a separate dip tube cutting machine for V-notch or slanted ends?

No. The Jinxin line cuts the end profile in-line during production - flat (square) cut, V-notch (custom angle), slanted cut or concave cut - with no secondary trimming. The buyer specifies the profile and V-angle in advance; Jinxin builds the matching cutter head and verifies it on your material during the pre-shipment trial.

06 Can one line cut several end profiles, or change the profile later?

Each profile - flat (square) cut, V-notch (custom angle), slanted cut or concave cut - is formed by a dedicated cutter head built to your specification. The shape and V-angle must be confirmed before production and cannot be changed after the head is made; additional profiles need additional heads, which can be quoted together. The servo flying-knife then cuts that profile to length in-line, without stopping the line.

07 How do you ensure the dip tubes fit valves and pumps without falling off?

The key is stable OD and roundness - and verifying it the way assembly actually works, not only by measuring numbers. Jinxin controls OD and roundness through matched die tooling, vacuum calibration and synchronized haul-off, with cut ends formed in-line for clean edges.

During the factory test run, Jinxin uses a stainless steel plug gauge matched to the tube specification to test the actual fit - sliding the gauge into the tube confirms whether the clearance is right for assembly. This is closer to real pump and valve fitting than reading caliper numbers alone.

If the buyer can send their actual valve or pump components, Jinxin can also test-fit against those. Most dip tube producers do not assemble the final pump, so plug gauge verification is normally sufficient to confirm that the tube meets the fitting specification.

08 Can one line cover multiple applications, tube sizes and small batches? What do I change when switching?

Yes. Lotion pump, perfume pump, aerosol valve and trigger sprayer dip tubes share the same extruder platform - the differences are in tooling, cut-end profile and collection method.

To be specific about what changes: switching tube OD requires changing the die and core (each OD has its own tooling set), along with the matching calibration sleeve. Vacuum and haul-off synchronization are reset, but the main extruder does not change. The practical approach for multi-size production is to have a tooling set for each commonly used OD, then swap tooling between runs rather than locking the line to one fixed size.

The quotation should be based on the buyer's actual tube family - how many ODs, which cut-end profiles, which collection method - not a generic high-speed catalog model.

09 What is the lead time, warranty and packing for ocean freight?

Lead time is confirmed according to configuration, tooling, electrical setup and factory test-run requirement. Many standard dip tube line projects are commonly planned around 50-60 working days from deposit. Warranty is quoted by full-line scope and component terms. Packing uses fumigation-free wooden crates, anti-rust protection and moisture-proof film, with larger stainless-steel tanks packed separately when required.
