Processed Metal Products

We propose the optimal manufacturing method based on material, shape, dimensional accuracy, and size to achieve the specifications of the target parts.

TECHNO ASSOCIE, with its extensive knowledge of various manufacturing methods, is able to devise optimal process design with our affiliates and suppliers to build the optimal supply chain. We can also propose cost reductions by reducing material costs and man-hours based on drawings and the parts used.

We propose net shaping by warm and cold forging. We establish integrated production from forging to secondary processing and finishing.

Cold forging

Characteristics	Obtains the desired shape by plastic deformation without heating the material.
Advantage	Low thermal shrinkage, stable and accurate net-shape forming
Disadvantage	Formability may be limited depending on the material.
Fields	Anti-vibration rubber shafts, automotive engine and decelerator parts, gear parts, etc.

Worm forging

Characteristics	A process that heats a material to obtain a desired shape through plastic deformation.
Advantage	Because softened metal material is processed, complex shapes can be formed.
Disadvantage	Processing speed is inferior to cold forging because processing is done after heating.
Fields	Automobile fuel injection-related parts, engine-related parts, etc.

Heading

Characteristics	A method of obtaining the desired shape by plastic deformation without heating the material.
Advantage	Basically, it is specialized for manufacturing small parts, and the processing speed is faster than forging.
Disadvantage	Not as suited to processing large sizes as forging, and not suitable for processing complex shapes if the number of man-hours cannot be secured.
Fields	Screws, bolts, nuts, collars, etc.

By utilizing our own overseas plants, we can form rough materials in China and deliver them after machining and finishing at our plants in Thailand and Mexico.

NC lathe / Combined lathe

Characteristics	A method of finishing a rotating material into a desired shape by machining it with a blade.
Advantage	High-precision machining is possible because machining is performed automatically by a control device.
Disadvantage	Shape flexibility is more limited than with machining centers.
Fields	Automobile parts / Industrial equipment parts / Electric and telecommunication parts, etc.

Machining Centers（MC）

Characteristics	A construction method that finishes the metal material into the desired shape by cutting it with a rotating blade.
Advantage	Because the cutting tool moves and processes, it is possible to process more complex shapes than with a lathe.
Disadvantage	Productivity is inferior compared to lathe processing
Fields	Medical-related parts / Industrial equipment parts / Electrical and communication-related parts, etc.

Other gears, splines

We have many business partners who specialize in special machining such as gear machining and spline machining. We can also handle only secondary machining of cast blanks. We will provide the appropriate technology for the specifications you are having trouble with.

We will create industrial parts that can contribute to a new era by consistently conducting research, analysis, planning, and commercialization of new materials and technologies.

Die casting (aluminum, zinc, magnesium)

Characteristics	A method of finishing the shape of the mold by injecting molten metal into the mold.
Advantage	Filling with high pressure allows processing of products with good surface finish and high precision.
Disadvantage	Depending on the shape of the product, cavities may occur and the strength may decrease.
Fields	Automotive inverter cases / single-lens camera housings / heat sinks, etc.

Plaster and sand mold casting

Characteristics	A process in which molten metal is placed in a mold hardened with sand or plaster to obtain the desired shape.
Advantage	Although it is necessary to remold the mold after each molding, it is less expensive than metal molds and is often used for large products, small quantities, and prototypes.
Disadvantage	Surface finish is rougher than die casting and requires secondary processing.
Fields	Large and small quantity aluminum parts, etc.

MIM (metal injection molding) and sintering

Characteristics	MIM is a process in which metal powder is mixed with a resin binder and injected into a mold to obtain the desired shape. Sintering is a process in which metal powders are formed and heated to bond them together to obtain the desired shape.
Advantage	Net-shape , suitable for mass production
Disadvantage	Inferior strength compared to metal processing such as stamping and forging
Fields	Gears for precision instruments, rotating shafts for camera LCDs, automotive engine parts, etc.

Extrusion

Characteristics	A process in which heated material is extruded from the frame of a metal mold to obtain the desired shape.
Advantage	Suitable for mass production of long products due to its ability to form the same shape stably and continuously
Disadvantage	Dimensional accuracy may not be stable due to shrinkage during cooling
Fields	Metal pipe materials, sash materials, fence structural materials, heat sinks, etc.
