Powder Processing Service

Pulverization, classification, nanoparticle processing, and measurement. We serve the needs of outsourced powder processing.

We offer world-class outsourced powder processing services, including dry-type high-precision classification at a submicron level, pulverization to realize uniform super-fine powders, and nanoparticle processing to produce new materials. With our abundant experience in powder processing and advanced technologies, we are capable of various types of outsourced processing.
We are flexible enough to handle requests for high-mix low-volume production and accept orders for multiple processes including combinations of classification and pulverization. Our specialized technical staff consistently supports customers’ projects from processing request to manufacturing and after-sales follow-up.

Request for processing

First, we conduct a survey to understand what a client wants to do, so please let us know following information: the type of powder, processing details, particle size and granularity, quantity, and delivery date. Based on that, we select the equipment that realizes the request and propose the most suitable outsourced processing service.

Schedule adjustment and quotation

Once the processing details have been determined, including the preparation of raw material powder and the confirmation of the packaging style after processing, we proceed with presenting the quotation and adjusting the processing schedule. We are also flexible with sample manufacturing and short-time delivery.

Powder processing

We perform pulverization, classification, and nanoparticle manufacturing under conditions that optimize the product yield and manufacturing capacity while checking quality by granularity measurement and giving careful consideration to contamination.

Report preparation and technical support

We organize the processing service details such as the processing method, quantity, and quality, and submit a report that can be applied to the next outsourced processing. In addition, technical support is available including consultation and suggestions for improvement of powder performance.

Flow of powder processing

We offer powder processing services in accordance with the customer’s requirements, and offer integrated support from planning to technical support.

For outsourced powder processing, we provide total support from planning to technical support.
In the planning stage, we assume the quantity and yield as well as the target particle size and granularity based on past results, and propose the optimum processing method. It starts with a look at how we can achieve the customer’s goals.

The flow of processing includes inquiry, processing request, quotation/schedule adjustment, powder processing, report preparation, and technical support. For technical considerations, extensive experience and know-how about powders is essential.
In our powder processing service, we investigate from various aspects such as technical difficulty, equipment configuration, and cost, and make proposals that materialize customers’ goals while making use of our knowledge cultivated through more than 600 cases of actual processing per year.

Features

Offering a system of outsourced production equivalent to an in-house factory

We offer flexible services including the provision of quality reports and inspection data, confirmation of processing progress, and meeting the needs of any packaging style, such as cardboard boxes, paper bags, and flexible containers.
In addition, the processed materials and reports are delivered at the same time, which allows detailed processing results to be checked at the time of delivery.

Sales representative doubling as a person in charge of processing management

In principle, a sales representative doubles as a person in charge of processing management. As the person in charge can fully understand the details of the processing request, all tasks from the adjustment of test schedule to submission of the quotations can be performed in the shortest possible time.
We are also flexible with schedule changes.

Quality control in accordance with ISO 9001

Each manufacturing room is laid out independently and all processes from raw material unpacking to processing and packing of products are completed in a single room to prevent cross-contamination.
In addition, we are capable of a variety of quality inspection methods, such as electrical resistance, dynamic particle imaging, and microscopy.

Types of Processing

Pulverization

Pulverization method

Airflow-driven/High-speed rotation (dry type for all)

Suited for pulverization in the range of submicron to several hundred microns.
Applications cover a wide range from metals to minerals, ceramics, and chemical products, mainly including electronic materials. In addition, various types of pulverization, such as low heat and abrasive powder are achieved.

    For food and pharmaceuticals, equipment sales only

Classification

Classification method

Forced vortex type/Semi-free vortex type (dry type for all)

We meet the needs of delivering ultra-fine powder and purity upgrading of main components. Air classification is possible over a wide range, from several hundred microns down to the submicron level. In recent years, there are high demands for metal powder, inorganic materials, and high-performance plastics, mainly for electronic materials, and our classification accuracy has been highly valued.

Nanoparticle processing

Nanoparticle production method

Radiofrequency thermal plasma

A wide range of nanoparticles can be produced, including surface-coated metals, oxides, nitrides, fluorides, carbides, alloys, complex oxides, and core-shell alloys.
It is also capable of producing compound nanoparticles by feeding multiple raw materials at the same time and spheroidizing of raw material powders.

  • *
    Because this is a gas phase method using a reaction field with a temperature of 10,000°C, relatively any form of raw materials can be handled. Contamination-free manufacturing is possible because no combustion gas or electrodes are used

Measurement

Nisshin Engineering is at the forefront of powder processing technology and is also a world leader in powder measurement technology.
Experienced technical staff is responsible for measurement and submits the data with comments from an expert on the measurement.
