Every machine price guide on OriginalPricing.com follows the same rules, so you can judge each number for yourself. This page explains where our prices come from, how the live charts work, and what we leave out.
Every price says what kind of price it is
A machine has many prices. We label each one by type, with the date we saw it:
- Manufacturer list price: published by the maker on its own site.
- Dealer or retailer price: what a store is selling for today, not the crossed-out “original” price beside it.
- Supplier asking price: listings on sites such as Alibaba, Made-in-China and IndiaMART. These are what sellers ask, usually factory-gate and before freight, duty and installation, not completed sales.
- Used and auction prices: individual listings and closed auctions.
- Public purchase records: what a city, agency or institution reported paying.
- Owner-reported prices: figures people share about their own purchases on forums. We treat these as individual reports, not market data.
- Estimates: ranges published by manufacturers or industry guides, labelled as estimates.
How the live price charts work
- Where a seller publishes prices in a form that can be read automatically, our tracker reads it once a day and adds a dated point.
- Some sites, Alibaba included, block automated reading. Those prices are entered by hand with the date and marked “recorded by hand”.
- Nothing between recorded points is estimated, interpolated or simulated.
- Averages only combine comparable machines, and each chart says exactly which ones, for example “Average of 3 film blowing machines”. A median is shown only when there are at least five listings.
- A 30-day change appears only when we have prices from both ends of that period. Until then the chart says there is not enough history.
Currencies and countries
Prices stay in the currency the seller used. We do not create a country price by converting a foreign price, because freight, import duty, local tax, installation and support change the real cost. Where no reliable local price exists, we say “Quotation required” rather than guess.
Sources and checks
- We prefer primary sources: manufacturers, retailers, official records and the standards bodies themselves.
- Forum and community discussions are used for real buyer experience, quoted briefly and attributed to the forum and year.
- Each guide links to one or two of its strongest sources; other sources are named.
- Before publishing, every figure is checked against its source. Claims we cannot verify are removed rather than softened.
- New articles are checked against our existing guides so that each one is original and adds information the others do not.
Medical and regulated equipment
Guides to medical devices and other regulated equipment cover prices, procurement and regulatory status only. They are not medical, legal or safety advice; whether a device is suitable is a decision for a qualified professional.
Corrections
