Is it the same for matte or sandblasting stainless steel cutlery?

Is it the same level of process?

The two methods of treating the stainless steel surface are different.
The matt treatment method uses a matt liquid to complete the matt
electrolysis process. Sandblasting is the use of compressed air to
spray the abrasive toward the surface of the workpiece at a high speed.
The purpose is to improve the surface appearance quality by removing
the oxide layer, rust, etc. on the surface.

Many users will worry about the thickness after the sandblasting ,in fact it is no need to worry 
Sand blasting will remove the oxide layer on the surface; sandblasting abrasive  will not
be attached to the surface of the workpiece, and the workpiece will not be thickened.

 

 

If you have problems of the sandblaster blasting abrasives, there are factors and solutions will give you some knowledge
1. Run out of the abrasive. Turn off the air and refill the blasting abrasive.

2. The blast gun gets block. Turn off the air and remove the nozzle to check whether there is blockages.
3. Check whether the blasting meida is dry, because wet abrasive will cause accumulation. If wet abrasive cause this problwm, clean the gun and nozzle, discharge the abrasive, dry and seive it for resuing.
4. The compressed air with moisture enters into the machine not only causing wet abrasives but making the blasting hose damp and stick with medias. To avoid such conditions, equipping a dryer may be better.
5. Without sieve causing bigger dust and ununiform abrasive entering the media valve,
6. Filling too much blasting abrasive. Over-load of abrasive will cause unpressurized.

   Stone surface blasting is using sharpe-edged abrasives such as quartz, silicon carbide, river sand, steel grit, driven by compressed air to impact the stones resulting in a required decorated surface, also ideal and perfect for etching letters and patterns. We provide stone blasting machine to meet customer's demands.

   Stone blasting application is of a wide range, not only finish natural stone plate in stadard specifications, but also prepare lines, pillars, handrail, steps, corners and other irregular stones. Same as other methods of treatment, stone blasting supports both small and large area processing.

Sand blasting machine offers a wide application for all kinds of products and materials:

1. Pretreatment: process before electroplating, painting, powder coating and other covering process with absolutely clean surface, meanwhile greatly improves the coating adhesion and corrosion resistance.

2. Cleaning: remove oxides, dirts, impurities from castings, stampings, welding parts, heat treatment parts or other metals, clean surface of non-metal parts, clear spots of ceramic products, restore patterns.

3. Refurbishment: refurbish accessories of carts, motocycles, mechanical and electrical equipment, as well as eliminate fatigue stress, to extend the life.

4. Polishing: remove masks of all metal or non-metal surface, plastic, crystal, glass, matt process making upscale effect.

5. Moldings processing: matt and mist finishing of mold surface, graphic and text production, no harm to surface and ensure and accuracy.

6. Deburring: remove burrs of machinery parts and plastic injection parts.

7. Rework of defective products: remove unqualified coatings, colours and letterings.

8. Strengthenning: increase the hardness and eliminate the internal stress of metal parts, such as aircraft blades, springs, machining tools, weapons, etc.

9. Etching and anti-skid: etch patterns, text and antiskid for metal and non-metallic products, such as: marble, non-slip handle, seal, stone tablet.

10. Jeans decorating: achieve the decoration of scrub, bleaching, whiskeys on jeans.

1. The surface of parts will not be polluted by sandblasting process, parts and media will not cause chemical reactions.
2. Irregular shaped workpieces, hard-to-reach corners can be easily blasted by the machine while its difficult for manpower.
3. Sandblasting machine greatly improve the surface finishing productivity and quality, such as removing heavy rust and scales.
4. One blast cabinet can use various blasting medias: glass beads, white & brown corundum, steel ball, garnet, plastic abrasive, etc.
5.The media blasting machine allows all kinds of finishing process, such as refurbish vehicle parts, removing rust from metal, cleaning contaminants of parts, etc.

1)Working Principle:

Siphon Type - With the compressed air flowing in the blasting gun, the siphon action will create a negative-pressurized environment that sucks the abrasive and delivers to the blast gun nozzle, which attains the purpose of abrasive blasting on the parts' surface. For the Suction blast cabinet, the compressed air is the power source of both abrasive supply and speed accelerate.

Pressure Type - The direct pressure cabinet is specially designed with a pressurized vessel containing compressed air, which will (pneumatically)push the media to the nozzles through a media outlet valve, then blast them onto the target. The compressed air is the power source of both abrasive supply and speed accelerate.
2)Different Features:

Siphon Type

A: Suitable for light blasting job and general-purpose finishing

B: The abrasive delivery is much slower than pressure blaster

C: Achieve abrasive travel continuously through the machine.

Pressure Type

A: Perfect for removing heavy coatings and conteminants

B: The air push the abrasive 40% faster than siphon type, greatly increase the productivity.

C: The pressure vessel needs to re-pressurize and cannot work continuously.

There are 3 factors for refering to choose right polishing media and the proportion of media and workparts:
1. Shape: Polishing media manufactured in special shapes is to match different shapes of workparts, such as corners, holes, which required to be in good effect and avoid clipping into the workparts.
2. Material: the choice of polishing media material depends on the material and hardness of the workparts.
3. Delicacy: depends on the surface roughness before processed and required delicacy after processed.
