Sintra Plus

In tune with the needs of dental labs that demand a high degree of versatility from their zirconia sintering furnaces, Shenpaz has developed features that are unique to this industry niche.

The ShenPaz SINTRA oven, in my opinion, is the best sintering oven on the market today, both in features and price.
