Four furnace categories
The source catalogue lists four furnace category names: dental furnace as the general term, zirconia sintering furnace for zirconia blanks, porcelain furnace for ceramic work, and press furnace for pressed restorations. Each category answers a different firing need, and a laboratory should choose from the firing route its cases require, rather than from a general idea of a furnace. The sintering furnace selection guide explains those routes in general terms, and this category page links to it as the next step for a buyer who is still choosing.
Two of the four categories have named products on this site: the 12S fast sintering furnace under the sintering category, and the PF1200D porcelain furnace under the porcelain category. The general dental furnace and press furnace categories are listed without named product pages. Ask about named models in an inquiry. These categories act as signposts. A buyer who needs a press furnace can ask about it in an inquiry.
Sintering furnaces for zirconia
A zirconia sintering furnace fires a milled zirconia blank into its final strength and shade, and the firing cycle is the most consequential step after milling. The 12S fast sintering furnace is the named product in this category, described on its own page in plain language, with a product image from the official website showing a white upright furnace with a touchscreen and a round tray inside the chamber. That image is a product publicity image, not a factory photograph, and its caption says so.
Ask for the sintering curve and temperature for the exact furnace in an inquiry. The zirconia sintering guide describes the firing sequence in general terms, from milled blank to finished restoration, and points cycle questions to an inquiry for the exact blank and furnace together. A cycle borrowed from another blank family could damage a case, so the restraint here is a safety measure as much as an evidence rule.
Porcelain furnaces for ceramic work
A porcelain furnace fires ceramic and glass ceramic work through a different route from a zirconia sintering furnace, and the PF1200D porcelain furnace is the named product in this category. Its product page describes it in plain language, without a specification table. Ask for the table in an inquiry. A laboratory doing ceramic work should read that page alongside the sintering pages, and note that the two furnace types are not interchangeable, even though both involve heat and a chamber.
The distinction matters for ordering as well as for use. A laboratory that orders a porcelain furnace expecting it to sinter zirconia, or a sintering furnace expecting it to fire porcelain, will face a mismatch that no catalogue page can fix after delivery. Naming the blanks and the ceramic work in the inquiry, and asking which furnace route each one needs, prevents that mismatch before any money changes hands.
12S and 11S, recorded separately
Two similar furnace names appear in the sources: the 12S fast sintering furnace on the official website, and an 11s big chamber fast sintering furnace on a MIC listing. This site records them separately and does not merge them into one series, because the sources do not say they are the same series or different models of one line. The 12S has its own product page. The 11S appears as a listing title; ask about it in an inquiry.
A buyer who finds an 11S listing elsewhere should quote that title in an inquiry and ask whether it matches the 12S line described here, or whether it is a different furnace. That one sentence prevents a wrong delivery more reliably than any catalogue cross-reference, because listing titles change while the product description on this page stays stable. The inquiry form has room for the quoted title alongside the product name and quantity.
Furnaces beside milling machines and scanners
A furnace never works alone: it fires what a milling machine shaped, from a case a scanner captured, and it is finished with burs and glaze paste after firing. The digital equipment index shows that chain in order, and each furnace page links back to the milling and material pages it connects with. A laboratory buying a furnace should therefore confirm the blank family it will fire and the milling machine that shaped it, in the same inquiry, so the company can answer the combination.
Turnaround is the practical question most laboratories ask about a furnace, and the 12S name itself signals a fast sintering answer. Ask for the cycle time figure for that model in an inquiry. A laboratory that needs a turnaround figure should ask for it in an inquiry, naming the blank family and the quantity per cycle, and judge the answer on its specifics.
Choosing a furnace
Furnace choice starts from the blanks a laboratory fires most: zirconia blanks point to a sintering furnace, ceramic work points to a porcelain furnace, and pressed work points to a press furnace. Within sintering, the choice narrows to speed and chamber size, and the 12S page discusses speed in general terms. The selection guide develops those choices further, and it too stops short of printing a curve or a temperature, for the same safety reason.
Once a furnace category is chosen, the next step is the named product page for that category, and then an inquiry naming the furnace, the blanks to be fired, the quantity per cycle and the destination. Then confirm the minimum order quantity, lead time, shipping method and payment terms as buyer instructions, because those vary by order and destination. A furnace order benefits from that completeness, because installation and training questions can be raised in the same message.
