Our Customer
Disclose end user only.
Engine parts of high pressure die casting

These are our product samples. High pressure die casting parts made with aluminum casting alloy-ADC12 is now the leading material in Asian automotive and agricultural machinery manufacturer's gasoline and clean diesel engine and continues to use in gear case, Inlet Manifold, Water pipe, Water Pump, engine mounting bracket.

High performance full robotized die casting line

We have a total of eight sets of full robotized HPDC line. 


A mold releasing lubricant will be delivered to each line from a centralized pump. Our system has a recycling function and it is able to reduce liquid waste drastically.


A die casting machine, if the injecting condition might be out of control standard, machines will stop immediately and strictly.


A melting furnace is an individual one for each machine, and we can choose to hold-temperature optionally by soaked type electric heater.


An articulated robot will take off products from die casting machines, that hand will set products to auto trimming press machine. The machine will separate the product and runner-gate and conveyor delivers the product to the deburring worker.


He/she can get the product without runner-gate. On the other hand, another conveyer will return the runner-gate to the melting furnace automatically.


A melting furnace has two auto charging towers, one is for ingot and the other is for runner-gate. This system is able to reduce heavyweight work 50% than the old one, and it has a good effect on occupational health, too.

Our factory has no wall, so the natural breeze blows pleasantly through the factory.


Own mold design team and tooling shop

Our products are compatible with both customer requirements and high productiveness.


Mold is one of most important our technology for die casting business and we have our own mold design team and die tooling shop. 

The mold design team always design molds to satisfy various customer requirements, and at the same time, they are satisfying productiveness.


Our mold tooling shop is adjoined to die casting factory and they are also working for mold maintenance every day.

A lot of practice is more important than theory to be a mold technician, and it is a very strong point to be able to listen to candid feedback from die-casting factory directly every day.

So, our mold engineers and technic people have more practical Kaizen competence.


We are keeping a high local procurement rate for raw materials of mold in Thailand.

Shimadzu spectrometer
Yxlon X-ray machine NDI

Measuring and assuring product dimension is the most basic and fundamental matter for die casting. An automatic running function will help to improve the accuracy and reproducibility of inspection. 


Confirming raw material chemical specifications to the required specification is the most basic and fundamental matter for die casting.





The x-ray machine is one of the most popular processes of non-destructive inspection. we are manufacturing a lot of structural parts and it is the most important requirement for them to avoid internal defects.
