Fine powder processing by blasting refers to the precise processing of fine particles at a micron level, propelled at high speeds. It demonstrates powerful effects in roughening the substrate surface, engraving, and removing dross and smear after laser processing. The dry films used for blasting in industrial applications are applied to LCDs, organic EL displays, silicon wafers, and more.

The "shot peening process" using blasting aims to extend the lifespan of products by striking them with abrasive materials at high speed to create compressive residual stress, thereby enhancing metal fatigue strength. It has become essential in industries such as automotive and aerospace, and is used for extending the repeated lifespan of spring steel and increasing the torsional strength of shaft materials. The abrasive materials used include "shot," "steel beads," "edgeless cut wire," "ceramic beads," and "glass beads." 【Features】 ■ Strikes the product with abrasive materials at high speed to generate compressive residual stress ■ Extends the product's lifespan by enhancing metal fatigue strength ■ Processing standards are also managed *For more details, please refer to the PDF materials or feel free to contact us.

The "sand removal" by blasting aims to remove casting sand, such as baked sand and core sand. The castings, which have been cooled for the necessary time within the sand mold, are separated from the mold frame or wooden frame along with the sand. The sand remaining on the surface of the casting is cleanly removed by blasting treatment. Additionally, the abrasive materials used are "shot" and "grit." 【Abrasive Materials Used】 ■ Shot ■ Grit *For more details, please refer to the PDF document or feel free to contact us.

The "cleaning" by blasting is intended for the removal of paint and foreign substances from the surface of products. Since soft abrasive materials are used, processing can be done without damaging the base material. Additionally, there is no concern about deformation due to heat, and because it is a dry blasting process, it improves workability and the working environment. 【Abrasive materials used】 ■ Zinc cut wire ■ Zinc shot ■ Plastic *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our company's "scale removal" using blasting. This process is aimed at removing "rust," "oxidation scale," and other contaminants adhered to the product surface, with the ability to adjust surface roughness depending on the projection conditions. Additionally, it can remove various scales and slags from rusted items, heat-treated products, welded items, and plasma-processed products. 【Abrasive Materials Used】 ■ Shot ■ Grit ■ Alumina *For more details, please refer to the PDF document or feel free to contact us.

The "pear skin treatment" by blasting adds value by roughening the surface to eliminate scratches and by creating patterns or a matte finish on the product. The finish resembles the rough texture of a pear's surface. Since no chemicals are used, there is no need for chemical water treatment after processing. It can be used for processing mobile phones, cameras, watches, glasses (bodies, parts, etc.), glass matte finishes, and frosted glass. 【Grinding Materials Used】 ■ Grit ■ Alumina ■ White Alumina ■ Stainless Steel Cut Wire *For more details, please refer to the PDF document or feel free to contact us.

The regeneration process is carried out by changing the type and grain size of the abrasive material based on the dirt and foreign substances attached to the target parts. 【Abrasive Materials Used】 ■ Zinc cut wire ■ Zinc shot ■ Glass beads *For more details, please refer to the PDF document or feel free to contact us.

• Processing Contract

Paint stripping by blasting" refers to the process of striking abrasive materials (grinding materials, media, or beads) against a workpiece to remove foreign substances and paint adhered to the surface. The type of abrasive material is selected based on the base material being processed, ensuring a finish without roughening the substrate. Since it is a dry process, only simple dust handling is required, allowing for odorless and safe operation. Additionally, damage to jigs is minimized, eliminating the need for spare jigs when outsourcing. 【Features】 - No need for drainage equipment or processing - Minimal odor and reduced risk during operation - Less wear and damage to jigs - Reduction in the number of jigs held - Shortened processing time *For more details, please refer to the PDF document or feel free to contact us.

The oversized workpiece is placed on a cart and brought into the blast room, where the operator manually operates the nozzle to blast the workpiece using abrasive material (particles) that is injected from the nozzle by compressed air from the compressor. The abrasive material after blasting is collected by a recovery conveyor, transported by a bucket elevator, and returned to the blast tank through a separator for recycling.

The shot blasting method introduced this time is a dry type, making it easy and safe to operate. Additionally, due to its compact design and short processing time, it significantly reduces the cost of surface preparation and improves quality (Class 1 cleanliness). The blasting method involves multiple upper and lower rotors projecting the material, and it is a fully automatic cycle where the workpiece is suspended from a crane for processing. The crane types HDF and SHF are available in a series.

The surface treatment of lightweight, durable, and easily processed aluminum, particularly for improving hardness and weather resistance, is effectively achieved through anodizing (anodic oxidation coating). At the same time, it can be colored in various shades, adding high value. Please consider adding Nichu's blast machine to this anodizing process. We have newly introduced a low-energy, airless blast machine that does not use a compressor, which can also handle large-scale and uniform processing. With Nichu's blast machine, you can achieve uniform surface treatment, eliminating complaints about the base treatment. Please feel free to consult with Nichu.

This is a device that has been improved for small screws, based on a direct pressure blasting system that is well-regarded for mold cleaning and similar applications. The abrasive material used for spraying is made of plastic, which is gentle on plating, allowing for the quick removal of adhered resin without damaging the screw. The sprayed abrasive material is automatically collected and reused, making it economical (the consumption rate is approximately 3-5% on average). It can be comfortably cleaned using a dedicated screw support (which varies depending on the screw size).

In conventional devices, air blast cleaning of long screws requires manual rotation and movement of the screw during the operation. While it is possible to easily rotate the screw with supports, the thicker and longer the screw shape, the more time and physical effort it takes. The automated mobile air blast device for screws is designed to automate the cleaning of such long screws without the need for manual labor.

We have a track record of delivering not only smooth shapes but also items with slight protrusions. Depending on the product shape, we can adjust the width of the belt conveyor, processing quantity, and finishing state to modify the transport speed. Since it is a belt conveyor system, the finishing on the back side will require a two-pass process by inverting the item. However, by configuring two machines with an inverter in between and arranging the layout accordingly, automatic front-side processing is possible. As long as it is within the load capacity and effective dimensions, continuous processing is feasible, and there is no concern about dents between products.
