Tips to Pick a Reliable Zirconia Sintering Furnace for Your Dental Lab
Choosing the right zirconia sintering furnace directly affects your lab’s yield, rework rate and throughput. We break down key evaluation criteria and introduce our WZ‑1600, WZ‑1800S and WZ‑1900 sintering furnaces for labs of different production volumes.

Running a dental lab means constantly balancing production output, finished‑product yield and long‑term operating costs. Many lab owners and technicians tend to focus mainly on price when shopping for a new sintering furnace. However, minor fluctuations in temperature during the sintering cycle often result in cracked zirconia crowns, inconsistent crystallisation and costly rework that eats into your profit.
Before placing an order, there are several practical factors worth checking carefully.
First is temperature uniformity and reliable gradient heating, which is critical for stable results on multi‑shade gradient zirconia.
Second, check the maximum batch capacity, to see whether the furnace can handle your rush orders during peak seasons.
Third, confirm whether the machine requires regular empty firing. Frequent empty firing wastes time, power and delays your production schedule.
Finally, pay attention to the service life of heating elements and local after‑sales support, as these greatly cut your long‑term downtime.
We offer three models to match labs with different daily workloads.
The WZ‑1600 is our compact entry option. It supports fast sintering and holds up to 50 crowns per run, perfect for small labs or clinics with lower daily crown output.
The WZ‑1800S sits in the mid‑range, with a capacity of up to 150 crowns in one cycle. It suits growing dental labs that need to expand output without stepping up to our largest unit.
Our flagship WZ‑1900 intelligent zirconia sintering furnace targets medium and high‑volume dental labs. It supports pollution‑free gradient sintering and can sinter up to 400 crowns in a single run. It removes the need for frequent empty firing and delivers consistent heating performance to lower your rework rate.
If you are planning to upgrade your existing furnace or comparing different suppliers, you can contact us to get our standard sintering curves and internal lab test records for your evaluation.
