Industry

How to ensure traceability in aerospace dispensing?
Encrypted process logs support 20+ years of traceability for military batch control.
What adhesive is used for EV battery pack sealing?
Two-part thermal/structural adhesives with A/B ratio ±1%, metered by a screw pump.
How is automotive electronics dispensing reliability verified?
Follow IATF16949 with IP67 sealing, -40°C, vibration and salt-spray tests.
What compliance matters for medical device dispensing?
Meet FDA / ISO13485: material traceability, process validation and complete batch records.
What cleanliness is required for semiconductor packaging?
Class 1000 or better is recommended, with particle control and ESD protection.

General

What is the warranty period?
12 months for standard machines; core valves can be extended with recommended maintenance.
Can you customize for our production line?
Yes. Non-standard integration with vision, weighing, MES and existing fixtures is supported.
Do you offer sample testing?
Free sample dispensing and process evaluation with customer materials before confirming the solution.
What products does FHATC offer?
Nano-precision dispensing: feeding systems, piezo jet valves, screw valves, curing and line integration.

Selection

UV or thermal curing?
UV for photo-curable adhesives, thermal for structural/silicone; dual-cure for dark or shadowed areas.
How should the feeding system be configured?
Select by viscosity, shot size and takt: pressure pot, screw pump, piston pump or heated lines.
How to feed high-viscosity epoxy stably?
Use a metering screw pump with heating and inline degassing to keep shot consistency.
How to choose between screw and piezo valves?
Use screw valves for high viscosity, high flow and continuous coating; piezo jet valves for micro-dose, high takt and non-contact.

Valve Selection

Cleaning and maintenance interval?
Clean when changing adhesive or after idle >8 hours; routine service every 3–6 months.
Can jet valves handle high-viscosity adhesives?
Yes, up to hundreds of thousands of cP with heating and high-pressure drive.
What is the minimum shot size of a piezo jet valve?
About 0.2 mg for non-contact piezo jet valves, with dose variation of ±1%.

Process

How to keep bondline uniform on 3D surfaces?
Vision scans surface height and compensates path and volume automatically.
How are dispensing paths programmed?
Teach pendant, CAD import and offline simulation; irregular paths can be generated automatically.
How is two-part mix ratio accuracy guaranteed?
Inline dynamic mixing reaches ±1%, with a static mixer for uniformity.
How to stop stringing and tailing?
Valve suck-back, temperature control and break-path optimization remove stringing.
How to control bubbles during UV curing?
Use a nitrogen dispensing chamber plus pre-degassing for zero-bubble curing.

Accuracy

Can vision compensate incoming part variation?
Yes. Position and angle offsets are compensated in real time at ±5 μm.
How is inline weighing used?
Weigh after dispensing versus the target; out-of-spec shots are corrected or rejected, and data can be uploaded.
What dispensing accuracy can be achieved?
Vision closed-loop positioning reaches ±5 μm, with even higher repeatability.

Integration

Is multi-valve synchronization supported?
Dual/quad valve sync is available for two-part and high-takt multi-station lines.
How long does line integration take?
Standard machines: 1–2 weeks; custom lines typically 4–8 weeks after evaluation.
Can the equipment connect to MES?
Yes. Output, yield, process parameters and traceability data can be reported.

After-sales

How are spare parts guaranteed?
Seals, nozzles and common parts are stocked, with remote diagnosis and fast shipping.
Do you provide operator training?
Yes. On-site installation, commissioning, process parameters and daily maintenance training.
What is the lead time for standard equipment?
About 4–6 weeks for standard machines; custom projects are quoted separately.
What is the after-sales response time?
7×24 support; urgent issues are handled within 4 hours.
