STEP FORWARD!

Manufacturing for a dreamy tomorrow,
bringing the smart Mishima brand more to the world!

Our IC tray business has developed from mold tooling technology. We respond to our customers' various specifications and requests with our advanced technology. Our combined monthly production capacity in Japan and overseas is 2 million pc/month, giving us the No. 1 market share in Japan at over 40%.

What is an IC tray (Semiconductor carrier tray)?

Semiconductors are used in all kinds of products, including cars and mobile devices. This IC tray is used in the transport and heat treatment of this semiconductor manufacturing process.

Point01
One-stop supply of high-performance, high-quality products through precision molding technology

In order to maximize the use and characteristics of the products requested by our customers, we provide a full range of services from material manufacturing, product design, mold design, mold manufacturing, and molding product manufacturing.

In product design, we perform optimal structural analysis and design, such as "design using 3D CAD" and "shape optimization proposal by flow analysis", to realize cost reduction through weight reduction and stability of "warpage and dimension" of products.

We also assist customers with quick development, including prototype requests.

Point02
Establishment of an "integrated production system" that carries out all processes in-house

1. Development and production of resin composite pellets

In-house production controls the quality of resin composite pellets, the molding material for IC trays.

Customization according to customer requirements and consideration of resin composite pellet development according to needs are also possible.

We develop and produce resin composite material pellets filled with carbon black and carbon fiber based on thermoplastic resins ranging from general-purpose plastics to engineering plastics.
We can also select resins and fillers according to customers' requirements and study the development of resin composite pellets.

4. Measurement/Appearance inspection

Environment-friendly "manufacturing" with a perfect quality control system

The control center is located in Japan, and the products from the Chinese factory are also subject to a thorough quality control system.

In order to meet the demands of environmentally friendly customers, we are fully equipped with measurement devices and conduct surveys
on environment-related materials.
In particular, we use fluorescent X-ray analyzer to inspect environmentally hazardous substances, and we can also inspect each material lot
and lot of molded products.
