How we work
Check first, then quote.
- SendPart number, or furnace model + photo of the old element.
- We checkWe reply in writing with the size line we read and anything missing.
- You confirmSize, elements per set and, for SiC rods, resistance grouping.
- Quote & productionThe quote covers the confirmed element and quantity.
Production & testing
Raw material, firing and power tests, checks against the size line, and packing in foam and crates.
Photos show typical production, testing and packing of elements of these types – not a specific order. Elements are brittle at room temperature; packing details are confirmed with the quote.

Before you ask for a price
Why don’t you just send a price?
Because a price for the wrong size helps nobody. Two elements that look the same can differ in diameter, centre distance or length. We first confirm the size line with you; the quote then covers that exact element and quantity.
Can you tell which element my furnace needs from its name?
Not from the furnace name or a part number alone. Our reply writes out the size line we read from your photos and dimensions, so you can compare it with the old element before you confirm anything.
What is the difference between 4/9 and 3/6 MoSi2 elements?
The numbers are the diameters in millimetres: hot zone / terminal. A 4/9 element has a 4 mm heating section and 9 mm terminals; a 3/6 element has 3 mm and 6 mm. Many dental sintering furnaces use 4/9; fewer use 3/6, and some documents write the size as 9/4. The two sizes are not interchangeable, and lengths and leg spacing still differ between furnaces, so the furnace model and a photo of the old element are needed.
Why does the centre distance matter so much?
The legs of a U element pass through holes or slots in the furnace roof or wall. Leg centre distance is measured centre to centre (a for MoSi2, A for SiC U rods), and it differs between furnaces even when the diameters are the same: a 6/12 element, for example, comes with different centre distances. A few millimetres decide whether the element goes in, so we always ask for it if it is missing.
Do SiC rods need to be matched by resistance?
Yes, for rods that run together. SiC resistance is specified hot (around 1000 °C), so a room-temperature multimeter reading says little; the value or test current marked on the old rod is the reference. Element handbooks commonly give ±5 % between rods in series and ±10 % in parallel, and recommend changing an aged group as a set. Tell us how your rods are connected; resistance grouping can be discussed in our reply.
Do you supply anything other than these six elements?
This site covers six heating elements only. If you also need accessories for the elements, tick the box in the form and note which ones in the comments. For any other size of these element types: send the part number.
Does sending a request commit me to anything?
No. A request is a question about one element or one list; you decide after our reply.
