With MIM (Metal Injection Molding), even the ultra-fine pins of the nozzle can be produced without machining.

High-precision metal parts with a size of several millimeters can be mass-produced.

The photo shows a nozzle of a fiber manufacturing equipment part produced using MIM (Metal Injection Molding). The hole diameter at the tip is φ0.3mm, and the length of the protrusion is 2.8mm, making it extremely fine. By mixing metal powder and resin, then injecting and sintering it in a mold, we can mass-produce highly precise machine parts like this. In mass production, we can expect a significant reduction in lead time and costs compared to machining. Castem has researched MIM, a technology developed by NASA, and has independently obtained a U.S. patent. We have over 30 years of manufacturing experience. We have produced parts for medical devices and aerospace components that require high precision.

[Example] Ultra-precision molding of complex shapes

Achieving extremely small and complex shapes without machining! Please feel free to contact us regarding metal parts.

A small-diameter hole shaped like a conical tube, with a tip diameter of φ0.3±0.05 and a length of 2.8 mm, has been achieved without machining. Additionally, it has no burrs inside and possesses the necessary strength to prevent chipping or breaking. When dealing with multiple pieces of such shapes on a needle holder through machining, the cost and time are significantly high. With our MIM technology, which allows for ultra-precision molding, high-precision parts under 1 mm can be mass-produced without machining. 【What is MIM (Metal Injection Molding)?】 It is a manufacturing method also known as metal powder injection molding. This process involves injecting a mixture of metal fine powder and a binder (adhesive) into a mold, then removing the molded product and performing debinding and high-temperature sintering in a vacuum furnace to create metal products. We specialize in obtaining ultra-small metal parts with high precision, complex shapes, and three-dimensional geometries that are difficult to machine. Our company is the only one in Japan that develops the raw materials used for MIM in-house. We offer the best proposals for our customers through various technologies. Please feel free to contact us through our website for any inquiries regarding metal parts.
