Product Example

- Yukaki -

under development

Dissolve, vaporize, fractionate plastic (PP, PE, PS) by high frequency and reduce it to heavy oil / gasoline etc.

- Subcriticality -

亜臨界 Perform garbage disposal and soil improvement. Perform sterilization and make soil suitable for vegetable cultivation.

  • 100% Organic Fertilizer created by "Subcritical Water Treatment" contains same level of Nitrogen in the are. Therefore it does not attract insects.
  • 100% Organic Fertilizer created by "Subcritical Water Treatment" elicits the potency of farm products, thus sufficient growth can be expected under the normal abundance of Nitrogen present in the air.

- Low‐Temperature Pyrolysis -

磁力式低温熱分解装置 Perform garbage disposal and soil improvement. Perform sterilization and make soil suitable for vegetable cultivation.

  • Organic material processing equipment which does not use fuel at all except for the initial lighting method
  • Smooth organic matter at low temperature with air containing magnetic ions
  • Flame-retardant organic matter can be easily treated, almost no harmful substances are generated
  • Installation cost is 1/3 compared with thermal incinerator
  • Pyrolyzed at low temperature without fuel and produce ceramic ash as a by-product

- Agriculture -

Working on a method that allows vegetable cultivation for all the year in all environments.

- Ecology Development Equipment -

Solar panel recycling device (Nagano prefecture new business development subsidy) Ueda area promotion office, We are working with five regional associations.


- Thread Cutting Die -

Our company's die is a part of the machine that creates the uneven part of a screw. Various roll dies are still widely available both locally and abroad. Dies are highly evaluated for their superior performance and quality, and by this technology they can be rolled without shaving materials to produce screws. It is the main strength of our Dies that it can produce screws that are much stronger than the screws produced by cutting. Our company has been the official roll dice manufacturer of Tsugami Corporation.

- Equipment Introduction -

- Overview -

  1. Procurement of parts for special machinery, assembly, wiring, integrated production up to operation adjustment.
  2. Procurement of control panel components, manufacturing, wiring and integration

Our company is engaged in manufacturing and processing machine parts, including injection molding machines that produces plastic products. We also assemble various special machines, wiring and operation adjustment.

- Manufacturing and assembly of injection molding machine
Accumulated Achievements -

Our current main production items are injection molding machines. Up to now, as a designated cooperative factory of Nissei Plastic Industry Co., Ltd., we are accepting orders among the company's injection molding machines, from parts manufacturing up to assembly and operation adjustment, and we have accumulated results through integrated production.

◆ Achievements heretofore

• Electric NEX series

NEX5, NEX15, NEX30… and such

• Small precision molding machine NP series

NPX7, HMX7… and such

• Hydraulic type horizontal molding machine NS series (small machine)

PNX40, PNX60, FNX80… and such

• Vertical Forming Machine ST Series (Small Vertical Type Machine)

STX10, STX20, TH5… and such

Synergistic effects are expected from injection molding machines accelerating the plasticization of parts used in automobiles and other small electric products. Internationalization of corporations has progressed throughout the years. But despite this harsh progression, we are continuously striving and devoting comprehensive efforts and challenges high quality and advanced technology.

Definitely, we also manufacture orders for various special machines, as well as process parts aside from that of our company. With our know-how, we may be able to provide support. Please do not hesitate to consult with us for any requests.
