Development of New Technologies

We won the 2009 Grant to Support for Development by Small and Medium Manufacturing Enterprises for our “100% No-defect Guarantee of Net Shape Through High Precision Forging” project.

Development of a conveyance method for short items and control of material distribution

Objectives

By conveying formed products that can’t be conveyed during the cold forging process, we expanded the variety of processing possible during cold forging. We also minimized corner sagging, which is a weakness of cold forging, and reduced the mold load by making adjustments to the cold forging process and the mold structure and by controlling distribution of materials.

Effects

This enabled the cold forging of transfer press products on the plate and reduced product costs by eliminating the cost of materials.

Improvement of the processing lubrication performance by using a spray machine to blow lubricating oil

Objectives

Lubricating oil contributes significantly to reducing friction between the material and the mold during the cold forging process. Excessive application of lubricating oil causes failures in shaping and imposes a load on the mold. Spraying lubrication oil on the product prevents excessive application and also reduces the load on the mold and the environmental burden due to the treatment.

Effects

Applying only the required amount of lubricating oil on the product reduced the environmental burden by significantly cutting the amount of oil used. It is also superior to the previous method because it allows easy application over the whole product.
