Extrusion, injection and even twin screw cleaning can be done without harsh chemicals or long hours of hand cleaning. Our effective blasting media, used in conjunction with the Maxi-Blast Mobile Screw Cleaning System, reduces cleaning time to an average of 30 minutes per screw.

The recommended media grade, Maxi-Clean (MC), is blasted out of a pressurized blast hose that only strips surface buildup, leaving the screw untouched and undamaged. The screw is then ready for reuse with no further cleaning or prepping needed.

In the cryogenic shot-blast deflashing process, our patented cryogenic grade polycarbonate media (CG) is blasted at rubber parts by means of a turbine blast wheel that spins at speeds of up to 6,000-10,000 RPM. The media impact parts (frozen by means of liquid nitrogen) are tumbled in the blast machine. Temperatures can reach 300o F (-184o C), effectively freezing the flash, or the excess where the mold halves meet, which is created during the rubber molding process.

This process will quickly deflash parts in an approximate 3-5 minute cycle. Once the parts emerge from the blast system and warm to room temperature, they are perfectly shaped with no signs of flash or damage.

Our extensive line of deflashing media offers plastic molders various options for deflashing plastic parts without having to worry about particle lodging. Polycarbonate grade (PC) is best for tough deflashing applications, while polyamide grade (PA) is tailored toward appearance parts. For smaller, more sensitive parts we offer a polystyrene grade (PB).

The media are blasted by means of a turbine blast wheel rotating at speeds of up to 6,000 RPM, or by air pressure nozzles at up to 90 PSI (6 bar). Where the two mold halves meet, flash, or burrs, is created. Upon impact with the media, the flash breaks off in an approximately 3-5 minute cycle, resulting in perfectly clean and deflashed plastic parts ready for assembly.

Deburring metal parts with Maxi-Blast plastic media is a unique and effective application. Many zinc and aluminum die castings require only light deburring without affecting the part surface; Multi-Blast (MB), PC and PA media work well for this non-abrasive deburring. Also, machined metal parts have loose burs that can easily be blasted away without affecting the surface.

Huge time savings can be achieved with either ambient or cryogenic deflashing/deburring of zinc, aluminum and machined metal parts in 3-5 minute cycles as opposed to old style vibratory tumbling, which can take 30-60 minutes to wear away burrs. This can be done by either turbine wheel blasting or by air pressure blasting. With plastic media deburring, the surfaces and edges are perfectly sharp and left in die cast or machined condition as opposed to tumbling and vibratory deburring, which slowly wears down edges and roughens surfaces.

The Maxi-Blast Mold Cleaning System is ideal for cleaning molds, dies and tooling with speed and efficiency. Molds do not have to be disassembled for cleaning because the system is able to hold the entire mold. Molds do not need to be cooled down either, as the plastic media is still effective on hot molds.

Hard-to-reach corners and small cavities are easily cleaned with media specifically designed and sized for mold cleanings, such as our Maxi-Clean grade (MC). The plastic media is continually recycled, increasing longevity and cost savings. With a range of media hardness, residue and mold fouling are easily removed without surface damage.

Media blasting to strip paint or remove powder coatings is a far more effective and safer method than chemical cleaning or hand stripping. Parts will not be damaged, nor will there be surface pitting or contamination. In minutes, the part is stripped and ready for re-coating.

Parts can easily and quickly be stripped in the Pressure Blast System with no exposure to hazardous chemicals. For more sensitive substrates such as fiberglass, favorable results can also be achieved with a softer grade of media like Maxi-VI (MS) or acrylic (AC).

Along with being ISO 9001-2008 registered, Maxi-Blast has achieved MIL-SPEC approvals for Type II and Type V plastic blast media (Mil-P-85891). Maxi-Blast has also been approved as a supplier for GE Aircraft Engines, Rolls Royce Aircraft Engines and many major airlines, aircraft component manufacturers and MRO's worldwide.

Both the military and aerospace industries utilize Maxi-Blast plastic blast media to strip paint and coatings from wheels, landing gear, propellers and rotors, generators, aircraft engines and other critical aviation components. With plastic blast media, consistent stripping is achieved and there is no need for chemical strippers.
