Posted by [Steve Wilson](https://blog.coldjet.com/author/steve-wilson) on Jul 22, 2025 1:09:36 PM Share this post - [Tweet](https://twitter.com/share) 🎧 Listen to the article 5:22 # Dry ice blasting is the most effective deburring and deflashing method It is not uncommon for unwanted material to be left on a plastic part after machining or molding. Burrs can be the result of numerous manufacturing processes: grinding, drilling, milling, turning, tapping, slotting, etc. They can manifest themselves in the forms of various types: roll-over, tear, flag and even poisson burrs. It is **essential to remove this unwanted material** from the manufactured part **without altering the dimensional tolerances or marring the surface**. So when deflashing and deburring becomes necessary, [a quality solution is also essential](https://www.coldjet.com/dry-ice-blasting/applications/deburring-deflashing/). Whether in removing parting line flash or material burrs, **traditional methods have often fallen short**. These methods can be slow, involve human error and inconsistencies, cause grit entrapment, and cross contamination. ![Deburring plastic part](https://blog.coldjet.com/hs-fs/hubfs/Deburring%20plastic%20part.webp?width=3832&height=2146&name=Deburring%20plastic%20part.webp) ## Dry ice blasting is an effective deburring and deflashing solution **Dry ice blasting** ensures that the geometries of the finished part are maintained without the negative side effects of alternative methods.   **The dry ice blasting process:** - Does not alter finished product geometries - Eliminates cross contamination - Is effective for removing all types of flash and burrs - Reduces part finishing time and lowers costs - Leads to consistent quality   ## Dry ice blasting doesn’t alter finished product geometries Dry ice provides a strong, but gentle touch **without causing damage to parts**. On the Mohs Scale of Hardness, dry ice is close to the bottom (1.5 – 2 out of 10) and is therefore **non-abrasive** on most materials. Dry ice successfully removes burrs from parts **without altering the dimensional characteristics of the part nor damaging the surface**. When compared to batch (tumbling) deburring processes, the dry ice blasting stream can be **focused on just the specific area** of the part that needs the excess material removed, which results in greater precision. Tumbling the entire part can cause damage in areas that didn’t even need to be addressed. The gentle cleaning process is also used to clean molds, which results in extending the asset life of the mold far beyond what would be achieved with traditional cleaning methods, such as chemicals or water. Cleaning tooling with dry ice eliminates the wear on the parting lines and shut-offs. Such unneeded wear **eventually leads to part flash**.

Once dry ice hits the surface that is being deburred or deflashed, it sublimates, or turns directly from a solid to a gas, upon impact, **leaving no residue**. ## Dry ice blasting effectively removes various flash or burrs Despite its gentle touch, dry ice effectively removes flash and burrs from a **variety of surfaces**. Dry ice has been successful on most plastics and some rubbers, especially thermoset polymers. It has also had effective results on Nylons, PEEKs, Polycarbonates, ABS, Acetals, Delrin, PPE, Turcite, Ryton, EPDM, and more.     ![deburr 3d printed ALIF part](https://blog.coldjet.com/hs-fs/hubfs/deburr%203d%20printed%20ALIF%20(Anterior%20Lumbar%20Interbody%20Fusion)%20part.webp?width=4140&height=2894&name=deburr%203d%20printed%20ALIF%20(Anterior%20Lumbar%20Interbody%20Fusion)%20part.webp)   ## Dry ice blasting reduces deburring and deflashing time and lowers costs Dry ice blasting greatly improves the efficiency of manufacturers by **reducing the amount of time spent removing burrs and flash** and the associated costs. The process can quickly remove burrs and flashes, which is counter to manual deburring and deflashing that can take minutes per part. Dry ice does not create secondary waste, further cutting cleaning time and downtime.   ## Dry ice blasting leads to consistent quality of finished parts Removing sharp instruments from employee’s hands not only improves plant safety, but **eliminates inconsistency that can come from manual cleaning**. This is especially true if multiple people are involved in the parts finishing process. Dry ice blasting systems deliver a consistent flow of dry ice particles to remove flash and burrs in a **repeatable fashion, regardless of who is operating the machine**.   ![Automated Deburr Deflash](https://blog.coldjet.com/hs-fs/hubfs/Automated%20Deburr%20Deflash.jpg?width=1904&height=948&name=Automated%20Deburr%20Deflash.jpg) ## What is the best dry ice blaster for deburring and deflashing? The Cold Jet PCS ULTRA is the most versatile dry ice blasting machine on the market. Equipped with our patented particle control system (PCS®), this machine offers operators complete control of the particle size being blasted to fine-tune their blasting parameters for each unique deburring and deflashing application. From 0.3mm to 3.0mm, and every tenth of a millimeter between, this machine allows operators to select from 1 of 28 particle sizes to dial in their blasting parameters for optimal performance. This allows the operator to clean delicate surfaces without altering the finished product geometries. ![cold jet aero2 pcs ultra dry ice blaster](https://blog.coldjet.com/hs-fs/hubfs/PCS_ULTRA_1200x600.jpg?width=1200&height=600&name=PCS_ULTRA_1200x600.jpg)   ## In summary Dry ice has been proven to be an **effective and quick method to deburr and deflash parts** without causing damage to the part finish, causing media entrapment issues, or causing cross-contamination concerns. So instead of manual deburring or deflashing parts, or tumbling problematic parts, consider dry ice blasting. This process eliminates cross contamination, changes in part geometries, and secondary waste.   [![New call-to-action](https://no-cache.hubspot.com/cta/default/3271929/d31e8021-b11b-4133-be3b-a6e2bbeb9e98.png)](https://cta-redirect.hubspot.com/cta/redirect/3271929/d31e8021-b11b-4133-be3b-a6e2bbeb9e98) [Plastics](https://blog.coldjet.com/tag/plastics), [Deburring and deflashing](https://blog.coldjet.com/tag/deburring-and-deflashing) ### Subscribe Here! ## Featured posts ### Posts by Tag -

Because dry ice rates only 1.5 to 2 on the Mohs hardness scale, it cleans without damaging dimensional tolerances, mar surfaces, or wear down precision features." }, "name" : "Is dry ice blasting good for deburring and deflashing?" }, { "@type" : "Question", "acceptedAnswer" : { "@type" : "Answer", "text" : "Dry ice blasting effectively removes all common burr types created by manufacturing processes including grinding, drilling, milling, turning, tapping, and slotting. This includes roll-over burrs, tear burrs, flag burrs, and Poisson burrs. The process is also effective for parting line flash and material burrs left from molding operations. Because the dry ice blast stream can be focused on specific areas of a part rather than processing the entire part, manufacturers can target individual burr locations without affecting surrounding geometries." }, "name" : "What types of burrs can dry ice blasting remove?" }, { "@type" : "Question", "acceptedAnswer" : { "@type" : "Answer", "text" : "Dry ice blasting has been successful on most plastics and many rubbers, especially thermoset polymers. Documented effective materials include Nylons, PEEK (polyetheretherketone), polycarbonates, ABS, acetals (including Delrin), PPE (polyphenylene ether), Turcite, Ryton (PPS), and EPDM rubber. The non-abrasive nature of dry ice combined with adjustable pellet size and pressure means materials sensitive to other deburring methods can be processed without surface damage, dimensional changes, or material loss." }, "name" : "What materials can dry ice blasting deburr or deflash?" }, { "@type" : "Question", "acceptedAnswer" : { "@type" : "Answer", "text" : "Dry ice blasting offers several advantages over batch tumbling deburring. Tumbling processes the entire part, which can cause unintended damage to areas that didn't need deburring — flat surfaces get marred and precision features get worn down. Dry ice blasting can be focused on just the specific area of the part that needs material removed, delivering greater precision. Tumbling also creates cross-contamination risks when different parts share media in the same machine, while dry ice sublimates on impact and leaves no residue. Tumbling can take minutes per part for thorough results; dry ice blasting removes burrs quickly with no secondary waste to clean up afterward." }, "name" : "How does dry ice blasting compare to tumbling for deburring?" }, { "@type" : "Question", "acceptedAnswer" : { "@type" : "Answer", "text" : "No. Dry ice blasting is non-abrasive and preserves dimensional tolerances and surface finish. Dry ice rates only 1.5 to 2 on the Mohs hardness scale, making it softer than virtually any substrate it cleans, and the pellets sublimate from solid to gas on impact rather than transferring impact energy into the substrate. The process removes burrs and flash without altering the dimensional characteristics of the part, marring the surface, or eroding precision features. This makes dry ice deburring viable for high-tolerance applications including medical device components and other precision-machined parts." }, "name" : "Does dry ice blasting alter part dimensions or surface tolerances?" }, { "@type" : "Question", "acceptedAnswer" : { "@type" : "Answer", "text" : "Cross-contamination is a serious concern in batch tumbling deburring, where different parts share media in the same machine and residue from one part type can transfer to another. Dry ice blasting eliminates this risk entirely. When dry ice hits a part surface for deburring or deflashing, it sublimates from solid directly to gas, leaving no residue or media on the part or in the workspace. Each part is processed with fresh dry ice and no transfer medium remains, so cross-contamination between parts or batches is impossible by design." }, "name" : "How does dry ice blasting eliminate cross-contamination in parts finishing?" }, { "@type" : "Question", "acceptedAnswer" : { "@type" : "Answer", "text" : "Dry ice blasting is faster, safer, and more consistent than manual deburring. Manual deburring can take minutes per part and depends on operator skill, leading to inconsistency when multiple workers are involved. Removing sharp instruments from workers' hands also improves plant safety by reducing repetitive motion injuries and accidental cuts. Dry ice blasting systems deliver a consistent flow of dry ice particles to remove flash and burrs in a repeatable fashion, producing the same finish quality regardless of who is operating the machine. The labor reduction also lowers per-part finishing costs." }, "name" : "Why is dry ice blasting better than manual deburring?" }, { "@type" : "Question", "acceptedAnswer" : { "@type" : "Answer", "text" : "The Cold Jet PCS ULTRA is the most versatile dry ice blasting machine for deburring and deflashing applications. Equipped with the patented Particle Control System (PCS®), this machine gives operators complete control over particle size from 0.3mm to 3.0mm — 28 distinct particle sizes in 0.1mm increments — allowing precise tuning of blasting parameters for each unique application. This level of particle size control is essential for deburring delicate surfaces without altering finished product geometries, and lets the same machine handle both gentle precision work and more aggressive flash removal by simply adjusting the particle size setting." }, "name" : "What is the best dry ice blaster for deburring and deflashing?" } ], "url" : "https://blog.coldjet.com/is-dry-ice-blasting-a-good-solution-for-deburring-and-deflashing" } ``` ```json { "@context" : "https://schema.org", "@id" : "https://blog.coldjet.com/is-dry-ice-blasting-a-good-solution-for-deburring-and-deflashing#breadcrumbs", "@type" : "BreadcrumbList", "itemListElement" : [ { "@type" : "ListItem", "item" : "https://www.coldjet.com/", "name" : "Home", "position" : 1 }, { "@type" : "ListItem", "item" : "https://blog.coldjet.com/", "name" : "Blog", "position" : 2 }, { "@type" : "ListItem", "item" : "https://blog.coldjet.com/is-dry-ice-blasting-a-good-solution-for-deburring-and-deflashing", "name" : "Is Dry Ice Blasting a Good Solution for Deburring and Deflashing?", "position" : 3 } ] } ``` ```json { "@context" : "https://schema.org", "@id" : "https://blog.coldjet.com/is-dry-ice-blasting-a-good-solution-for-deburring-and-deflashing#webpage-augment", "@type" : "WebPage", "about" : [ { "@type" : "Thing", "name" : "Deburring", "sameAs" : "https://en.wikipedia.org/wiki/Deburring" }, { "@type" : "Thing", "name" : "Deflashing" }, { "@type" : "Thing", "name" : "Burr (edge)", "sameAs" : "https://en.wikipedia.org/wiki/Burr_(edge)" }, { "@type" : "Thing", "name" : "Parts finishing" }, { "@type" : "Thing", "name" : "Dry ice blasting", "sameAs" : "https://en.wikipedia.org/wiki/Dry-ice_blasting" } ], "alternativeHeadline" : "Dry ice blasting is the most effective deburring and deflashing method", "inLanguage" : "en-US", "mentions" : [ { "@type" : "Thing", "name" : "Injection molding", "sameAs" : "https://en.wikipedia.org/wiki/Injection_moulding" }, { "@type" : "Thing", "name" : "Mohs hardness scale", "sameAs" : "https://en.wikipedia.org/wiki/Mohs_scale" }, { "@type" : "Thing", "name" : "Sublimation", "sameAs" : "https://en.wikipedia.org/wiki/Sublimation_(phase_transition)" }, { "@type" : "Thing", "name" : "Thermoset polymer", "sameAs" : "https://en.wikipedia.org/wiki/Thermosetting_polymer" }, { "@type" : "Thing", "alternateName" : "PEEK", "name" : "Polyether ether ketone", "sameAs" : "https://en.wikipedia.org/wiki/Polyether_ether_ketone" }, { "@type" : "Thing", "name" : "Polycarbonate", "sameAs" : "https://en.wikipedia.org/wiki/Polycarbonate" }, { "@type" : "Thing", "alternateName" : "ABS", "name" : "Acrylonitrile butadiene styrene", "sameAs" : "https://en.wikipedia.org/wiki/Acrylonitrile_butadiene_styrene" }, { "@type" : "Thing", "alternateName" : "Acetal / Delrin", "name" : "Polyoxymethylene", "sameAs" : "https://en.wikipedia.org/wiki/Polyoxymethylene" }, { "@type" : "Thing", "name" : "Nylon", "sameAs" : "https://en.wikipedia.org/wiki/Nylon" }, { "@type" : "Thing", "alternateName" : "Ryton", "name" : "Polyphenylene sulfide", "sameAs" : "https://en.wikipedia.org/wiki/Polyphenylene_sulfide" }, { "@type" : "Thing", "name" : "EPDM rubber", "sameAs" : "https://en.wikipedia.org/wiki/EPDM_rubber" }, { "@type" : "Thing", "name" : "Tumbling (surface finishing)", "sameAs" : "https://en.wikipedia.org/wiki/Mass_finishing" }, { "@type" : "Product", "name" : "Cold Jet Aero 2 PCS ULTRA", "url" : "https://www.coldjet.com/our-equipment/dry-ice-blasting-equipment/aero2-ultra-series/aero2-pcs-ultra/" }, { "@type" : "Product", "name" : "Particle Control System (PCS)" }, { "@type" : "Product", "name" : "Cold Jet Integrated Blasting Equipment", "url" : "https://www.coldjet.com/our-equipment/integrated-blasting-equipment/" }, { "@type" : "Service", "name" : "Deburring and Deflashing with Dry Ice Blasting", "url" : "https://www.coldjet.com/dry-ice-blasting/applications/deburring-deflashing/" }, { "@type" : "Service", "name" : "Plastics & Composites Industry Applications", "url" : "https://www.coldjet.com/dry-ice-blasting/industries/plastics-composites/" } ], "name" : "Is Dry Ice Blasting a Good Solution for Deburring and Deflashing?", "primaryImageOfPage" : { "@type" : "ImageObject", "height" : 2894, "url" : "https://blog.coldjet.com/hubfs/deburr%203d%20printed%20ALIF%20(Anterior%20Lumbar%20Interbody%20Fusion)%20part.webp", "width" : 4140 }, "speakable" : { "@type" : "SpeakableSpecification", "cssSelector" : [ "h1", "h2", "h3" ] }, "url" : "https://blog.coldjet.com/is-dry-ice-blasting-a-good-solution-for-deburring-and-deflashing" } ```
