Ferro-Plast distributes in Italy the DIEBLAST SYSTEMS brand: high performance blast media for a wide range of applications including cryogenic and ambient deflashing, mould cleaning and paint stripping.

High Performance Plastic Shotblast Compounds
Available in three hardness grades DIEBLAST PRIME high performance shotblast media have been developed to obtain maximum efficiencies in deflashing and deburring operations. The high impact strength and abrasion resistance of DIEBLAST PRIME compounds provide significant technical and commercial advantages over standard plastic shotblast systems.

DIEBLAST PA
Based on high molecular weight nylon 6 polymer, the individually cut pellets of PRIME P.A. blast media are ideally suited for the deflashing of urea, phenolic and melamine thermoset mouldings.

DIEBLAST PM
Harder and more agressive than nylon blast media, DIEBLAST P.M.is used where additional impact strengths and greater cutting power are required in the deflashing of glass reinforced compounds i.e. S.M.C. / B.M.C systems.

DIEBLAST PC
With maximum hardness and impact strength, PRIME P.C. was initially developed for the deburring of alluminium diecast mouldings. Using unique crosslinked polymers, PRIME P.C. high performance pellets are also used for cryogenic shotblast applications at -40°C.

High Performance Cryogenic Shotblast Compounds.

Developed specifically for the cryogenic deflashing of rubber mouldings DIEBLAST CRYSTAL and DIEBLAST PENTA PRIME are produced from 100% crosslinked polycarbonate resins.

The unique polymer structure of DIEBLAST compounds offers significant technical and commercial advantages over standard polycarbonate resin used in cryogenic deflashing systems.

Reduced Media Consumption

At sub zero temperatures polycarbonate resin becomes brittle and the surface of the granulate erodes due to impact stresses within the blasting cycle.

This erosion or breakdown rate increases as the temperature is lowered until the granulate fractures on impact. Standard polycarbonate resins disintegrate @ - 80�C. While DIEBLAST compounds retain their structure and integrity throughout the cryogenic cycle withstanding temperatures to -140�C.

With DIEBLAST compounds retaining their size, shape and integrity longer, greater efficiencies within the blasting process are achieved.

The higher performance and quality of DIEBLAST compounds offer substantial cost reductions by lower media consumption, shorter blast cycle times and reduced liquid nitrogen consumption.

Each micro pellet of DIEBLAST contains anti-static agents and will continue to perform as an efficient cryogenic blast media long after standard polycarbonate systems have been reduced to dust.

DIEBLAST Silicon and DIEBLAST cube are subject to international patent application.

High Performance Non-Abrasive Blast Cleaning
The sharp, angular particles of thermoset resins act as an ideal medium when surface contamination needs to be removed with no abrasion of the substrate layer. Faster, cleaner and less costly than chemical solvents systems DIEBLAST TS was initially developed as an efficient replica-watch.cn cheap christian louboutin shoes, non toxic method for the paintstripping of aircraft fuselage with zero damage to the delicate, aluminium substrate.

DIEBLAST TS non abrasive shotblast media is now used in a wide variety of application areas ie Deflashing plastic mouldings, deburring aluminium diecasting and the blast cleaning of composite materials, epoxy, polyester and fiberglass structures.

The cleaning of mould tools in the rubber industry is an ideal application area for DIEBLAST TS non abrasive blast media.
Chemical cleaning of mould tools is costly and time consuming, while conventional bead blast cleaning can be used this tends to abrade the tool surface changing critical dimensions and substantially reducing the tool life.

DIEBLAST TS efficiently cuts through the residual build up of contaminants release agents etc restoring the tool profile to its original condition, with no erosion of the tool surface or change in mould dimensions.

Technical advances in the design of cryogenic shotblasting equipment have enabled the process of deflashing complex, precision rubber mouldings to be carried out with consistent and reliable results. Increased thermal insulation, accurate blasting parameters and a more efficient distribution of blast media have all contributed to reduced costs, higher quality and improved throughput speeds.

One area of the deflashing process that has failed to keep pace with these developments is the continued use of polycarbonate resins as the blasting media despite the considerable advances in polymer engineering over this period. At room temperature polycarbonate resin is a tough, resilient material with good impact strength and a high resistance to surface abrasion. However once the temperature falls to sub zero levels, the polymer becomes brittle and starts to breakdown into dust, reducing the shotblasting efficiency.

Once the temperature reaches -30°C the blast media has lost almost 70% of its original impact strength and this rapid deterioration in mechanical properties continue to -80°C when the polymer structure can fail completely.

While the addition of plasticizers can overcome many of these problems, the resulting blast media is soft and inefficient with poor abrasion resistance and low kinetic energy.

These inefficiencies in the deflashing process require excessive use of blast media, liquid nitrogen consumption and blasting wheel speeds to compensate for this poor performance.

Recent innovations in molecular engineering have enabled base polycarbonate resins to be crosslinked with various fluoro polymers that withstand the challenging conditions demanded in high performance cryogenic shotblast applications and equipment. Increased performance greater efficiencies and reduced cost combine with improvements in quality standards exceeding those found in standard blast compounds.

Cubic Engineering

Standard polycarbonate shotblast media is normally manufactured in the form of cylindrical granulate 30th diam (0.75mm) being the most common size for the deflashing precision mouldings.

In depth analysis of deflashing results show that cubic granulate are more efficient throughout the blasting process. The addition of extra corners and cutting edges enhances performance while the mass and kinetic energy produced by each particle is increased by up to 27%.
With both DIEBLAST grades retaining their size and shape longer than standard blast media this greater efficiency is maintained throughout the blasting cycle down to -120�C.

Breakdown rates in blast media either by surface erosion or fatigue failure have more dramatic and adverse affects on the efficiencies in cryogenic applications than conventional room temperature blast systems.

A 10% erosion on the surface of standard 45tho (1mm) granulate, reduces the kinetic energy by almost 50%.

Operating at only half its efficiency, the blasting process requires lower temperatures, increased wheel speeds or extended cycle times to compensate for this loss in performance.

These changes in blast parameters lead to even higher media consumption and the production of "expensive dust".
