4. Sales Suggestions & FAQ

4.1 Sales Suggestions

Target the "small pouch liquid + capping" customer group — cosmetic pouches (day cream, hand cream, serum pouches), sauce pouches (salad dressing, ketchup, chili sauce small pouches), beverage small pouches (juice, wine, coffee pouches). Closer to pouch needs than small bottle fillers such as the PL-88, adds capping over the DF4-1000, and cheaper than large plastic sealing machines.
Lead with the "fully pneumatic, no power supply" differentiator — the DF4-1000 is electric control + pneumatic, while the DFF4 is pure pneumatic with no power supply. For alcohol-based products, explosion-proof workshops, outdoor filling and mobile stations this is a natural differentiator. It is also simpler than the DF4-1000 (no electrical control module), with fewer failure points and lower maintenance cost.
Lead with "filling + capping in one" — most competitors need a filler + capper + conveyor three-piece setup; the DFF4 does the job of two machines in one. This answers the customer's budget worry about "having to add another capper after filling".
Lead with "liquid and paste dual-purpose" — cosmetic and daily chemical customers often produce both liquids (toner, serum) and low-viscosity pastes (hand cream, facial cleanser); the DFF4 covers both on one machine, raising order value.
Bundle sales — pair it with our labeling machines and inkjet coders to build a small pouch + capping + labeling + coding line, upgrading a single-machine order into a complete line order.
Negotiate with video — the YouTube video (https://youtu.be/Gk-akHZNx0o) shows the machine at work; remote machine inspection replaces a factory visit and lowers the barrier to closing.
Be honest about the EXW scope — the EXW quotation excludes freight and spare parts; LCL sea freight, air freight and courier are quoted at cost per order, avoiding later disputes.
Proactively advise on seal selection — rubber sealing rings versus silicone O-rings should be chosen by liquid corrosiveness, so the customer does not buy the wrong seal and lose sealing performance after filling.

4.2 FAQ

Q1: Which liquids is the DFF4 suitable for? Is it really dual-purpose for liquid and paste? Yes, the DFF4 is genuinely dual-purpose — it fills liquids (water, oil, juice without particles, liquid detergent, sauce, wine, liquid cream, etc.) as well as low-viscosity pastes (thin sauces, hand cream, facial cleanser, liquid cream, etc.). Liquids with particles, high-viscosity pastes and strongly corrosive liquids are not suitable (strongly corrosive liquids require rubber sealing rings plus a 316 stainless steel configuration). The viscosity threshold for high-viscosity pastes is to be confirmed — please check with Andrea before ordering.

Q2: Does the DFF4 need a power supply? Is the control electric or pneumatic? The DFF4 is fully pneumatic and needs no power supply — connect an air compressor and it works, with no motor and no electric spark. It is simpler than the DF4-1000 (electric control + pneumatic): no electrical control module, fewer failure points and easier maintenance, making it especially suitable for alcohol-based products and filling workshops with high explosion-proof requirements.

Q3: Does the DFF4 include capping? What are the capping specifications? An integrated capping module completes filling and capping on one machine, saving a separate pouch-clamping capping station. The detailed capping specifications (torque, cap size, capping speed, etc.) are not listed in the PDF quotation and are to be provided by Andrea.

Q4: How many nozzles come as standard? Can I choose just one? 2 nozzles as standard. You can specify 1 head or 2 heads per order — fewer heads means a lower machine price, while 2 nozzles markedly increase small pouch output.

Q5: How do I choose the nozzle diameter? Selectable within 3–12 mm. For general liquids (water, oil, juice, detergent) a 6 mm nozzle head is most common; thin sauces, wine and cosmetics use an 8 mm nozzle head; thicker liquids use 10–12 mm. Confirm the pouch mouth size and liquid viscosity before ordering and Andrea will recommend the diameter.

Q6: How accurate is the filling? What can it achieve? Filling accuracy ≤ 1 g (absolute value), typical for a piston volumetric machine. Note that this is an absolute value, not a percentage — 1 g on 50 ml equals ±2%, and 1 g on 100 ml equals ±1%. We recommend weighing and calibrating 2–3 pouches before full-scale production.

Q7: Will the nozzle drip or leave residue at the pouch mouth? No. The bottom close positive shutoff nozzle is standard — at the end of the fill the cylinder drives a positive shutoff at the nozzle bottom, leaving no droplet and no residue. The pouch mouth stays clean and can go straight to the capping step.

Q8: What material are the product contact parts? What is the hygiene grade? Contact parts are food grade 304 stainless steel (316 optional) with a stainless steel valve system; the seals are food grade silicone O-rings rated to 200°C. The whole machine is food safe and can be used directly for food pouch filling.

Q9: Is it troublesome to change pouch sizes? Are change parts needed? No. The machine handles stand-up pouch, spout pouch, Doypack and common flexible pouches on the same unit; changing pouch type usually only requires the matching fixture / pouch clamp, and the fill volume is set through the piston stroke. The capping module's pouch clamp is also selected by pouch mouth size.

Q10: Is cleaning troublesome when changing liquids? No. The pipework uses quick-connect fittings and the contact parts are easy to dismantle; regular liquids rinse off with clean or hot water, while oils and sauces are best rinsed with hot water first and then clean water. When changing between strongly corrosive liquids, soak with the matching cleaning agent before rinsing.

Q11: How are MOQ, payment and delivery arranged? MOQ 1 set, EXW Wenzhou; T/T 100%, production and dispatch scheduled after payment; dispatch within 10 days (stock including necessary items). LCL sea freight, air freight and courier are all available, with freight quoted at cost per order.

Q12: How long is the warranty? What happens after the warranty period? One-year whole-machine warranty — faults not caused by human error and arising from normal use per the manual are repaired or replaced free of charge, with the customer bearing the freight from China to the destination. Paid lifetime maintenance is provided after the warranty period; if an engineer visit is required, the customer bears the round-trip travel expenses.

Q13: What is the packaging? How is overseas shipment inspected? Packed in a single reinforced carton including tools and parts. Net weight 95 kg, gross weight 100 kg, machine size 1850 × 550 × 1000 mm (horizontal layout); suitable for LCL sea freight, air freight and international courier. Packing size to be supplied by Andrea. We recommend requesting the latest container loading and outer carton photos before ordering.

Q14: Do you have CE certification? Yes. This model can be shipped with CE certification (please ask Andrea for the specific certificate number).

6. Workflow

6.1 Pouch Filling & Capping Process

Connect air — connect the air compressor and set the air pressure to the standard range (MPa value to be confirmed); check that the pressure gauge, filter and air signals are normal. The DFF4 needs no power supply, so there is no electrical connection step.
Load material — pour the liquid or paste to be filled into the feed tank (or feed it from the upstream line), and confirm that the contact parts use the seal material matching the liquid (silicone O-ring / rubber sealing ring).
Fit the pouch — fix the stand-up pouch / spout pouch / Doypack onto the matching fixture or pouch clamp with the pouch mouth aligned to the filling head; the filling head lift device adapts to the pouch mouth position automatically.
Select the mode and start — choose "foot pedal (semi automatic)" or "auto timer (automatic)" according to the day's production; both modes switch instantly on the same machine.
Volumetric filling — once started, air drives the piston and the 2 anti-drip positive shutoff nozzles fill simultaneously, completing dosing automatically within the 50–250 ml range (300–600 bags/hour).
Positive shutoff / anti-drip — when the target volume is reached, the cylinder drives a positive shutoff at the nozzle bottom, eliminating drips and residue at the pouch mouth.
Integrated capping — after filling, the capping station locates the pouch mouth and cap automatically, and the pneumatic capping module tightens the cap to the preset torque. Capping specifications (torque, cap size, capping speed) to be supplied by Andrea.
Unload / pass on — remove the filled and capped pouch and move it to the next step (labeling / coding / bundling / cartoning).
CIP cleaning / product changeover — when changing liquids, remove the nozzles and contact parts and rinse with clean or hot water; when changing between strongly corrosive liquids, soak with the matching cleaning agent before rinsing. Check the silicone O-rings regularly for ageing, deformation and air leakage.
