A surface treatment changes and alters the metal.

Electroless chemical polishing treatment

We accept and conduct a sample production for prototype plant in order to correspond the needs of deburring fabrication and surface treatment according to electroless polishing.

Delivery results

When the system utilizes an electroless solution, the system operates simultaneously a chemical polishing and a deburring of the parts which have been deposited for 1 to 10 minutes in the solution contained in a barrel or basket not by utilizing electricity or jig.

The performances have been already evaluated highly in Europe so that they are introducing and converting existing electrolytic deburring machine and the facility of Thermal deburring technology in to our system.

Scope of usages

It is suitable for the polishing and deburring treatments of carbon steel, low alloy steel and mild steel with carbon content of up to 1.3% that have been quenched or not.

If carbon content is lower than 0.4%, it becomes luster clearly, but it becomes light black if the carbon content is more than it.

It is applicable for various kinds of areas including precision machine parts, hydraulic devices, aircraft parts, automobile parts, and nozzle needles.

Effects

  • When the burrs on the whole surface deposit in the solution are removed, it becomes possible to operate a polishing smoothly into inner part of hole, lateral hole, and hollow.
  • It is possible to remove the burrs generated in deep part of hole by operating drill fabrication and polishing fabrication.
  • A surface is finished with a clean and complete metallic phase.
  • It makes available to manufacture precision parts within a tolerance level in aspect of control of metal solution removal quantity.
  • It generates oxygen only during the treatment so that it gets rid of any risk from hydrogen.
  • It does not induce any mechanical deformation that makes possible to treat parts with very thin thickness as well.
  • The treatment is operated indoors so that it does not induce any damage due to heat.

Electrolytic polishing treatment

Electrolytic polishing treatment is operated for stainless steel parts to obtain mirror surface with a high degree, uniformity, and high cleaning degree (out gas free, particle free, and contamination free), to restrain from any eruption of metal ions, and to generate immovable membranes.

Features

When a part is connected to the positive electrode (plus side), deposited in and electrolytic solution and then applied with current, the metallic surface is electrolytic removed, and the surface is polished and becomes smooth that the roughness is an order of micron. And sexivalent chrome is not contained in the surface.

Scope of available usages

All of stainless series, especially austenite series of SUS304, it is available to give a luster.

Dimensions of processing tank

800㎜×400㎜×500㎜:(width)×(length)×(depth)

Examples of usage

Food conveyer parts, medical and pharmaceutical plant parts.

Alumite treatment

Magnify the picture.

After a completion of mechanical fabrication, consequently it operates alumite treatment of aluminum alloy. Our alumite treatment is operated by manual in all.

A product treated with the alumite has not nay flows or scratches but the membrane is stabilize in a range of 1 micron that the quality is guaranteed.

  Weight per each(㎏) Dimensions of processing tank(㎜) Thickness of membrane(μm)
White alumite Up to 1kg 300×300×600 3~10
Black or green alumite Up to 1kg 200×200×600 10~20
