COLD FORGING

Cold forging is a processing method for casting unprocessed materials, such as nonferrous steel, stainless steel, alloy steel, and carbon steel, using a mold at room temperature.

Its manufacturing efficiency is high, and its cost performance for mass production is also high.

However, cold forging requires high-level know-how for mold designing and production, etc. Marui Industries emphasized cold forging earlier than other companies, and has researched and developed this technique since the early years of the inauguration of business.

Based on such efforts, approximately 70% of the products of Marui Industries are manufactured from cold forging materials, most of which are produced by Maruei Miyazaki Co., Ltd. (Miyazaki Prefecture, Japan) of the Maruei Group.

The integrated business from material production to sales in the group is one of the strengths of Marui Industries, and enables flexible response to customers'requests.

MACHINING

Machining means a technique to remove unnecessary material off the surfaces of angular or rod-shaped works, using cutting tools such as end mills, to realize desired forms and sizes.

In Japan, manufacturing with NC cutting equipment is common, and approximately 90% of production facilities of Maruei Industries utilize NC cutting equipment.

Marui Industries even develops the production facilities in collaboration with machine makers.

Machining is a processing technique used for products that need precise processing. All of the Marui Group companies conduct cutting, and compete with one another in quality and manufacturing efficiency.

Such a system enables the efficient sharing of know-how accumulated at each production facility, and leads to the improvements in technical capacities of the entire group.
