cehaGOLD is an innovative service that combines tried and tested materials with state-of-the-art technology. As a gold and silver refinery and centre of excellence for precious metals, C.HAFNER rounds off the materials offered by dental laboratories with precious metal frameworks fabricated using pioneering CAD/CAM technology – offering a fast and efficient solution without the need for costly warehousing.
Integrating the precious metal into the digital manufacturing process eliminates the need to maintain two different manufacturing processes (casting and digital manufacturing) in the laboratory. There is no need for expensive pre-financing and warehousing of precious metals.
The already very high material quality of precious metals is further improved by the industrial production of milling blanks with special processes, making cavities, pores or impurities a thing of the past. A perfect microstructure facilitates further processing in the laboratory whether through ceramic veneering or polishing.
Digital CAD design with evenly thin wall thicknesses allows for a reduction in the weight of finished pieces by up to 30% over cast structures. A milled unit weighs on average only 2 grams.
Difficulties in the production of complicated workpieces, such as telescopes or long bridges, are avoided with milling. Milled structures are also precise and largely stress-free.
Take advantage of our attractive trial offer and test our innovative “Precious metal milling” service: Your milling units will be manufactured for free until further notice – you only pay the alloy list price plus 10% processing loss! You are welcome to contact your sales representative to discuss individually adjusted terms and conditions.
C.HAFNER processes STL data from open scan systems or CAD software. To ensure absolute accuracy of fit, C.HAFNER supplies optimised settings for the dental lab’s CAD program based on the indication and material. The data delivered by the laboratory is transmitted by the “Zahnomat” tool or via e-mail.
cehaGOLD frameworks are cut from solid blanks of precious metals using state-of-the-art 6-axis milling machines. Careful adaptation of the milling strategies to the different precious metal alloys and indications guarantees an accurate fit as well as outstandig quality. The final step is a quality inspection followed by dispatch to the dental laboratory.
Innovative cehaGOLD milling technology caters for all applications of prosthetic treatment*. Six tried and tested high-grade precious metals alloys are used for fabrication.
* Component height is max. 15 mm. This may be exceeded in special cases.
We process *.stl data from open CAD systems such as Dental Designer (3Shape), Exocad or DentalWings. Our technical support team will gladly assist you in setting up the corresponding parameters (settings). Technical support can be reached on +49 (0)7044 90333 325.
We mill crowns and bridges (also fully anatomical), inlays and onlays, telescopes and bars for you.
The price per milling unit is €30. (not applicable for trial offer)
Additional retentions will be charged at €15, attachments at €30.
We calculate the used precious metal weight at the current list price minus precious metal markdown plus a processing loss of 10%.
We guarantee delivery within 48 hours (not inclusive of postage time) if data is received by 4:30 p.m., after which the 48-hour period for the next working day (Mon-Fri) begins.
Alternatively, we offer express production - delivery within 24 hours (not inclusive of postage time) for data received by 12pm and carries an additional charge of €9.50 per unit. If the data is received after 12p.m., the 24-hour period begins on the next working day (Mon-Fri).
We have no control over the delivery times stipulated by the postal service. You can choose between standard mail delivery (free of charge) or express delivery - before 12pm the following day (EUR 14.40).
