2016.9.9 See you at N-Plus exhibition in Tokyo.

We are attending N-Plus exhibition held at Tokyo Big Sight from Sep. 28th - 30th.

N-Plus is an exhibition of materials and technologies in manufacturing field, focused on “advanced performance” and “higher value”.

This exhibition is a cross-industry exhibition. It aims to enable both of the visitors and the exhibitors from various industrial fields to find out the new business opportunities under a common goal; developing the new products with “advanced performance” and “higher value”.

N-Plus consists of several specialized exhibitions. Each follows the concepts listed below.

- Lightweight High-Strength Materials

- Carbon Fiber Processing

- Plastic Film

- Adhesion Joining Fastening

- Coating Technology

- Heat Resistance and Dissipation Technology

- Soft Material Technology

- Nanoimprint Lithography

N-Plus info;

Show Period: Sep. 28– Sep. 30, 2016 10:00 - 17:00

Venue: Tokyo Big Sight, East Hall

Dymco Exhibition Booth: M-12, East Hall 3

We are going to display the products below.

- Suction/vacuum conveyer

- Double belt press and heating conveyer

- Electroformed nickel sleeve, flow forming stainless sleeve

- Micro-pattern mold belt

- Air roll

- Air bearing inertia roll

This is the great opportunity for all viswitors to learn our latest products and technology and to have direct communication with Dymco.

Micro pattern sleeves

Recently, it is increasing for us to provide moulds for nanoinprint with micro patterned surface.

Thickness of sleeve is around 0.05mm~0.3mm and materials are Nickel or SUS.

A process to make a master mould, sleeve is pressed fit onto an axis and polish as mirror surface.

After the sleeve is polished, it is curved micro pattern on the surface.

Micro pattern belt (Seamless Pattern Mould)

However, this means needs high precision machine tools and takes much time.

Also, the master moulds have lifetime so it is necessary to have a few moulds for mass production.

We have invented a new solution to make copy mould which is totally same as its master with transfer the micro pattern twice.

It does not cost like making new moulds by curving.

Example of micro patterned thin metal sleeve

The picture is an example but we could have smaller pattern recently.
We coat electroless nickel plating on nickel sleeve first and curve after press fit the sleeve onto an axis.

The patterned sleeve is used with pressed fit onto an axis of mass production machine.

To press fit, a specific skill is necessary so we usually manufacture the axis as well.

We deal with sleeves and axes for trial or mass production.

Web handling rolls #3 of 4 : Pattern-transcription sleeve

The third handling roll is a patterned mold roll.
This is to form minute patterns on plastic film and sheet surface.
Cylindrical thin-wall sleeve has patterns on its surface and
This sleeve is set onto the core air madrell.
As this roll continuously rotates, patterning is available on the roll to roll basis. This improves production efficiency over the process on sheet-to sheet basis.
