Aluminum die casting [Automotive parts, 2-wheel parts, general parts and office machine parts, etc.] ◆ Features The most commonly used die casting is aluminum alloy. This light and strong alloy has excellent corrosion resistant properties and is widely used in applications for various fields. ◆ Iwaki Diecast’s aluminum die casting production system We use a launder system, which enables us to always supply clean raw materials, when feeding the molten metal from the melting furnace to the holding furnace. The scrap material, which is generated during trimming, is returned to the melting furnace via an underground conveyor. Our casting equipment is automated featuring a unique manufacturing method that is both highly productive and very safe. It produces a smooth surface with a minimal number of blowholes. ◆ Melting process • Our melting is centralized with high thermal efficiency. • The molten metal is poured into the holding furnace using launders (troughs) and porters. • We supply clean molten metal with minimal temperature difference by using an electric furnace. ◆ Casting process • Our own automated and systematized facilities enable us to automate processes up to the separation of gates. • Our die temperature control enables us to make products of consistent quality. • Our management system CAMOS allows us to visually monitor the production status. ◆ Main usages Automotive parts, 2-wheel parts, general parts and office machine parts, etc.

【Proposal Of Near Shape】 Difficult to process materials like satellite are expensive and to process such materials into washer, color, or sleeve can be time consuming and costly. In such cases, lost wax casting can be effective in the way that it can transform a roll material into near finished shape. In other words, minimization of additional treatments, reduced processing time, and reduced cost. As a side note, depending on required precision, cast produces can be used without any other after treatments. 【Combination With Cheap Mould】 We use cheaper mold, “Quick System (lost wax mold price 49000 yen ~),” for a palm size (60x90x50) small lot (10 pieces ~) trial production. A combination with this system, greater amount of cost reduction can be expected. （Y.I）
