MST PRODUCTS MST : Miki pulley Sintering Technology MST that has changed the concept of P/M in a big way MST products is high performance P/M parts that is capable to be used instead of machined parts, and made possible by using MST (Miki pulley Sintering Technology). The MST allows high-density and complex geometry. It's total technology for filling, compaction and sintering mainly exclusive large CNC multi compaction press systems.

MST presses (500-ton and 1,000-ton) A high-output multistage CNC forming press is used to form high-density, high-accuracy, complex-shaped, and high-strength sintered parts. Mass measurement Mass measurement after forming. Examines all formed parts in-line. Acoustic nondestructive testing Performs non-destructive testing on all parts for internal defects and checks density after sintering.

Sintering furnace of continuous operation Parts formed with an MST press are sintered in a mixed atmosphere of nitrogen gas and hydrogen gas. A sinter hardening effect is obtained by controlling the cooling speed after the heating. Batch degreasing furnace Can perform batch degreasing and sintering after part forming. Supports varied testing purposes. Development/Quality testing equipment Can be prepared to perform diverse environmental, quality, and customeroriented tests.

MST products is the name for any part developed using the unique large multistage CNC forming press system (500-ton/1,000-ton) that provides a total system (filling through forming to sintering) for creating parts. MST products are high-density, high-precision, complicated shape, high mechanical strength parts that can be provided in small lots and at low costs. High Density High density can be achieved by a CNC press, high output, and uniform filling The strength of a sintered part is determined by elements such as the density, sintering conditions, alloy elements, and thermal processing. Of...

Complex Shapes Complex shapes can be achieved using a multistage CNC forming press MST products are formed using a multistage CNC forming press system that controls the pressure, position, and speed with a computer. This enables us to provide parts with a complex shape and large aspect ratio that were previously not possible. In addition, CNC control enables us to make parts with near net shape, without waste and with stable quality. This is an environmentally-friendly technique. Fill powder High Strength Move powder High density and high strength can be achieved using sinter-hardening materials...

Spur gear Material Fe-Ni-Mo type materials Mass 0.55 kg Density 7.1 g/cm3 For pressure lock gears used in injection molding machines. Large machined gears can now be produced via sintering. Outer rotor and the inner rotor Material Fe-Cu type materials Mass 0.3 —1.2 kg Density 6.8 g/cm3 High Density For large trochoid pumps. Sintering makes possible the manufacture of four types of rotors with varying thickness - traditionally produced via machining - with a single mold.

Various conditions of production ■ Conditions for parts that can be made from MST products ■ Iron parts ■ Punch area is 1,000 mm² or more MST products that are made at present are mainly sintered iron parts. The most popular parts are Fe-Cu parts containing 0.6% carbon. Needless to say, they can be processed thermally. MST products can also be made from 300 series stainless steel or other materials. Since presses for MST products are large (500 and 1,000 tons), very small parts are not suitable as MST products. The minimum Minimum diameter punch area of the part must Approximately φ40 mm be 1,000...
