Processing Operations
According to the requirements of the customer, we propose optimal processing methods such as metal and resin molding, sheet metal processing, cutting, and others.
We can handle various metal forming processes for all materials such as aluminum, copper and stainless steel.
For this manufacturing method, molten metal is poured into a mold to make a casting with a predetermined shape. This reduces mold cost and is suitable for small-lot, multi-type production.
This is one of various casting methods. It is suitable for mass production at reasonable cost, and enables high accuracy and the realization of complex shapes.
This is a casting method using wax. This reduces mold cost and is suitable for small lots and complex shapes.
This is a technology for baking metal powder together with binder at a temperature lower than the melting point of the metal. It achieves excellent dimensional accuracy and is ideal for mass production.
A method of forming a product by striking (forging) metal. It achieves superior strength.
We handle not only various resin moldings of materials such as PVC, nylon, polycarbonate, and Duracon, but also post-processing and finishing process.
This manufacturing method is to inject a heat-melted material into a metal mold where it is cooled and solidified. It is highly suitable for mass production.
This method forms a product with a fixed profile by pressurizing heated raw material and passing it through a metal mold. It is an optimal method for long products of the same shape.
With this method, the material is put into a heating metal mold, formed by applying pressure and heat while degassing, and the resulting product is then taken out after cooling. It is highly suitable for mass production.
With this manufacturing method, a film or sheet-like resin material is softened by heating and made to adhere to the mold. Mold costs for large products can be kept low.
With this manufacturing method, a resin softened by heat is extruded into a pipe shape, and compressed air is blown on the shape while it is soft to solidify the shape.
We propose optimal processing methods for processing steps such as bending, cutting, and drilling of sheet metal.
This processing method uses force to bend metals such as aluminum and stainless steel. We can handle sizes up to 8000 mm.
With this method, aluminum, stainless steel, and other metals are bent into a rounded shape.
Material can be partially cut using a press, turret punch press, laser, or similar.
With this machining method, a large number of holes are drilled in a metal for the purpose of saving weight, lighting, and so on.
Shearing, roll forming, spinning, planing, etc.
Angle cutting and precision cutting are available.
Pressing and milling are available.
Processing with a roll bender and triple roller is available.
Various assemblies
We propose optimal processing methods such as lathe processing and milling.
With lathe cutting, a workpiece is rotated and a tool blade is applied for machining.
A mill with multiple cutting edges is used for surface machining.
Cutting is performed by means of a plasma or laser beam.
Processing is performed by means of a pressurized water jet. This makes it possible to suppress deformation and alteration due to heat.
Cutting is performed by means of a fast-rotating saw.
We propose the most suitable joining method such as welding, crimping, studs, rivets, bonding, and bolting.
Spray painting with various solvents such as melamine, acrylic, urethane, and fluorine is possible.
Spray painting with various solvents such as melamine, acrylic, urethane, and fluorine is possible.
Applying a powder type paint can be carried out by electrostatic powder coating or fluidized immersion coating.
This environmentally friendly coating method makes use of the silver mirror reaction mechanism. It is compatible with various products such as exterior articles that require beautification.
This surface treatment technology forcibly oxidizes and coats the aluminum surface as an anode, mainly by utilizing electrolysis of water in strong acid.
This technology applies metal films such as gold, silver, and nickel to the surface of various materials such as metals, plastics, and ceramics.
This technology applies a thin film of vaporized metal to the surface of various materials such as metals, plastics, and ceramics.
