Micro processing hard-to-machine materials
Refractory metal like tungsten and rare metals are hard to machine and process. Creating small quantities, even one, is no problem for us. We always carefully listen to customers needs, and try our best to fulfill customers needs from designing stage of product to massproduction. Below are some of sample products we worked with our customer.

Resin tungsten
tungsten, normally a metel, is created by mixing powders, and then, compacting powders and sintered. Pure tungsten needs additional process of forging. These processes are lengthy, and costly. tungsten also is very heavy, hard and inflexible. Compare to normal tungsten, Resin tungsten is more flexible yet it still blocks radioactive substance.
Radiation sheilding cloth and epron
tungsten is one of densest metals, and it is heavy. When used as radiation sheilding materials , cloth and epron for example, resin mixed tungsten is used.
Resin tungsten sheet and board.
tungsten is one of densest metals, and it is heavy. When used as radiation sheilding materials , cloth and epron for example, resin mixed tungsten is used.
Resin tungstenweight for fishing
Resin tungsten sheet is heavy enough, and flexible for fishing weight, you can stick to anything.
Resin tungsten Molded products
Amount of resin content can be altered depending on desired density and flexiblity. Injection molding, extrusion molding, metal powder injection molding are all possible.

Welding and assembly
We are not limited to processing using machine, we also weld and assemble various kinds of parts. We are capable of doing laser welding, plasma welding, and resistance welding. We can also weld metals with different electric potential and melting point such as tungsten and Copper. We can also braze, shrink fit and/or metalize ceramics and metals. Coils can be thermal sprayed or coated by ceramics.
