--- title: Inert Baking slug: process/inert-baking description: Unlock the benefits of inert baking ovens with our comprehensive guide! Discover how nitrogen gas environments enhance resin properties, improve toughness, and ensure accurate colors for elastomers, all while facilitating larger batch productions. docTags: createdAt: 2024-06-28T18:39:42.614Z --- # Overview Inert baking ovens cure parts in a **low-oxygen environment, **filling the oven with nitrogen or another gas. For certain Carbon resins, inert baking offers advantages over standard air baking. For applications with **rigid materials** that require great toughness to pass functional testing, baking parts in a **low-oxygen environment** significantly improves **toughness **while retaining other desired characteristics. When rigid parts are baked in an inert oven: - **Elongation at Break** improves +60% for EPX 82 and +57% for EPX 150. - **Unnotched Charpy** improves by +200% for EPX 82 and +90% for EPX 86FR. - **Unnotched Izod Impact Strength** improves +33% for EPX 150. For **elastomeric** applications using EPU 44 or EPU 46, inert baking improves **color accuracy** and enables baking **larger batches of parts. **See [EPU 46 Baking Considerations](docId\:x4ZRiEhw1jRxSe-LBQYOF) for more information. ## Technical Data Sheets For detailed information on inert bake performance properties, see the following Technical Data Sheets: ::::VerticalSplit{layout="middle"} :::VerticalSplitItem **Rigid Resins** - [EPX 82 TDS](https://docs.carbon3d.com/files/technical-data-sheets/tds_carbon_epx-82.pdf) - [EPX 86FR TDS](https://docs.carbon3d.com/files/technical-data-sheets/tds_carbon_epx-86fr.pdf) - [EPX 150 TDS](https://docs.carbon3d.com/files/technical-data-sheets/tds_carbon_epx-150.pdf) ::: :::VerticalSplitItem **Elastomeric Resins** - [EPU 46 TDS](https://docs.carbon3d.com/files/technical-data-sheets/tds_carbon_epu-46.pdf) - [EPU Pro 50 & 90 TDS](https://docs.carbon3d.com/files/technical-data-sheets/tds_carbon_epu-pro-50-90-black.pdf) ::: :::: ## Recommended Inert Ovens Carbon has evaluated and recommends the following inert ovens: ::::VerticalSplit{layout="middle"} :::VerticalSplitItem [Yuanyao Oven, Model YNO 225](https://www.yuanyao-tech.com/) ::Image[]{src="https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/DyU8huHvsNidicET4rqlr_image.png" size="72" width="1680" height="1802" position="center" darkWidth="1680" darkHeight="1802" showCaption="false"} ::: :::VerticalSplitItem [Blue M Oven](https://www.bluem.com/products/mechanical-convection-ovens/146-series-inert-gas-mechanical-convection-oven) ::Image[]{src="https://res.cloudinary.com/carbon3d/image/upload/t_auto_quality_format/v1754947830/Education/Process/Thermal-Curing/Inert-baking/Blue_M_Oven.png" size="48" width="454" height="726" position="center" darkWidth="454" darkHeight="726" showCaption="false"} ::: :::: ## Inert Oven Specifications If you choose to use a different inert oven from the ones recommended by Carbon, please ensure that the oven meets the specifications listed in this section. | **Description** | **Specification** | | --------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | O2 Concentration | Must be able to achieve 500 ppm or less | | Power Supply | 50-60 Hz (see table below) | | Ventilation | 3" or 4" exhaust port with damper with vent duct connected to exhaust port in accordance with local code regulations | | Cooling | Cooling with water coil | | Set Point Temp Variability | plus/minus 1° C | | Turnover Airflow | \<= 5 minutes | | Overhead Safety Temperature | >250° C | | Temperature Range | 15 C above ambient to >250° C | | Inert Gas Supply | 40 to 80 PSIG, 20 to 200 SCFH | | Seal Type | Gasket (bellofram can extruded this material is different dimensions): [Bellofam silicone 5104-NSF](https://www.belloframsilicones.com/silicone-products/5104-NSF-Certified-Closed-Cell-Silicone-Sponge-Extruded-ASTM-D-1056-2D1)

For additional information, refer to the product manual. ### Daily or Start of Operation - Inspect interior for debris. - Inspect door gasket and ensure that the door closes securely. Clean gasket as needed. ### Monthly - Inspect door gasket for any wear, cracks, tears, or any damage to the gasket. - Check that the door seals evenly around its perimeter to negate heat loss. Adjust door latches if necessary. - Check/adjust chamber pressures (purge flow + run flow). ### Quarterly - Clean the oven’s Interior.  ### Semi-annual (6 months) - Swap or clean the check valve (if equipped). - Check N2 flow meters (if equipped) adjust or replace if necessary. ### Yearly - Calibrate temperature. *** # Yuanyao Oven ## Product Manual Manufacturer document that contains safety, installation, operation and maintenance information. ::File{src="https://api.archbee.com/api/presign/uXbZOKjJTGpPhjapQ8fvM-RzSwB3LjgMhpHZwM2GgKz-20250211-062220.pdf" label="Yuanyao YNO-225 Nitrogen Oven Manual.pdf"} ## Baking Profiles The oven must be programmed for the specific resin you are using.

The popup closes.  The top left of the screen displays PROG STOP, indicating that the program has stopped running. When a bake in progress is terminated, the oven does not initiate cooling. However, the oven will gradually cool down. When the oven temperature gets below 50°, you can open the oven door.  Maintenance ----------------- Yuanyao Oven For additional information, refer to the [Yuanyao oven manual](docId\:HUKHDKofw9hthSe0dd8LY) above. ### Daily or Start of Operation - Inspect interior for debris. - Inspect door gasket and ensure that the door closes securely. Clean gasket as needed. ### Monthly - Inspect door gasket for any wear, cracks, tears, or any damage to the gasket. - Check that the door seals evenly around its perimeter to negate heat loss. Adjust door latches if necessary. - Check/adjust chamber pressures (purge flow + run flow). ### Quarterly - Clean the oven’s Interior.  Semi-annual (6 months): - Swap or clean the check valve (if equipped). - Check N2 flow meters (if equipped) adjust or replace if necessary. ### Yearly - Calibrate temperature. # General Safety & Notes ## Cryogenic Liquid Safety ### Nitrogen Handling - Cryogens ::::VerticalSplit{layout="middle"} :::VerticalSplitItem **Cryogenic liquids are liquefied gases that are kept in their liquid state at very low temperatures. ** - Cryogenic fluids are stored and used in special, thermally insulated containers, like this **dewar**. **Liquid nitrogen** is a cryogenic liquid that can be used in the inert bake process. - At a minimum, wear **protective cryo (thermal) gloves and a face shield** when connecting and transferring liquid nitrogen. ::: :::VerticalSplitItem ![](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/9JqC0NP52JYEuuYL-Jz0a_cryo.png) ::: :::: ### Cryogen Safe Work Practices When working with cryogens, follow these guidelines: ::::VerticalSplit{layout="middle"} :::VerticalSplitItem - verify that pressure relief devices are in place and functioning properly - if valves have snowballs accumulating do not use force to dislodge the ice - if the pressure gauge is rising unexpectedly, have the pressure relief devices checked - use smallest sized dewar possible for a given job - use good lifting practices - ensure that two employees move dewars, not one - secure dewars (empty or other) with straps to prevent tip-over during an earthquake ::: :::VerticalSplitItem ![](https://api.archbee.com/api/optimize/3CesIL2dYMCHPZvRjp8S0/zP8cN49CUKuUV2Ka957dM_dewars-600px.png) ::: :::: When transferring liquid nitrogen from a large dewar into a transport dewar, ensure a diffuser is used. ## LMA Notes At this time we recommend baking **EPX 82** or **EPX 86FR **in this oven through either air or inert bake schedules. A potential fire risk exists if you operate your oven at temperatures in excess of the Carbon recommended bake profiles. See more information about LMA in [Thermal Curing](docId:7NE6rGdaSzpAPOHH5QOzm). # Contact Information ## Carbon For questions and support related to inert baking parts made with Carbon resins, please contact [Carbon Support](docId\:K86Zo5vcyN_wqJL3vdGFt). ## Blue M Blue M 2821 Old Route 15
