What To Include For An Accurate Quote

A bottle packaging machine is quoted from four facts about your line.
Cover them in your first message and skip a whole round of e-mails.

Sample Bottles or 3D Drawings

The fastest route to a firm quote is a set of real bottles by courier — change parts are then built to your bottle, not to a guess. STEP or IGS drawings are a good starting point.

Write it asA set of each bottle type

Bottle and Neck Specification

Material and geometry decide the tooling: PET or HDPE, bottle height and diameter, the neck finish size — and whether one machine must change over between several bottle types.

Write it asPET or HDPE, neck size in mm

Line Speed in Bottles Per Hour

Your blow moulder sets the pace for every machine downstream. Tell us its hourly output, and each station is specified so the new equipment never becomes the bottleneck.

Write it asBottles per hour, per bottle type

Plant Voltage and Destination Port

Control cabinets are built with European, American and Japanese electrical components to match your national standard — name your voltage and frequency, plus the destination port for shipping terms.

Write it asVoltage with Hz, port name

Only making bottles so far, or planning a whole new line? Say so — complete line solutions start from the same four facts.

The Sample Bottle Test Run

You Send Bottles. The Factory Sends Back Proof.

The proof step this industry is built on: two parcels travel between your plant and Zhangjiagang —
and before any machine ships, you have already watched it run on your own bottles.

Before You Order

Ordering, Warranty and Support Questions

The commercial details buyers usually settle in the first two e-mails — answered up front.

How does the sample bottle test run work?

Courier a set of your bottles to the factory in Zhangjiagang. We fit the change parts, run your bottles on the actual machine and send you the test video together with the processed samples — so you approve results, not promises, before shipment.

What does the two-year warranty cover?

Every Longsn machine carries a two-year warranty, and spare parts are free of charge within those two years. Parts are sent out to keep your line running.

Do you install the machine and train our operators?

Yes. Longsn can send professional engineers to your plant to install the machine and train your workers until they can operate it confidently on their own.

Where do Longsn machines run today?

Longsn machines work in more than 45 partner countries. The factory sits in Zhangjiagang on the Yangtze River, adjacent to Shanghai, so sea and land shipping are both convenient.
