Tour of Our Factory


Hydraulic Press Production Line

 

We have 7 hydraulic press machines. The pressing capacity is from 100T to 400T and is mainly used for pressing deep drawn metal parts. For example, our standard products such as access doors (up to 600x450mm, dia.1250mm) and iris dampers (up to dia.800mm).

Progressive Die Pressing Production Line

 

We have 10 progressive die pressing machines in our production facilities. Their total capacity is from 110T to 160T. Many of our products have been upgraded from a single-transfer die to a progressive die due to the high efficiency and stable quality. They are used for making corners, G-clamps, access doors, DSC regulators, holders, etc.

Robot Arm Transfer Production Line

 

The two robot arm transfer production lines are serving for the production of the big volume products such as iris dampers and metal air valves. This automatized solution has significantly improved our productivity and also reduced the labor force numbers.

We have further plans to increase the numbers of robots in our factory for the existing production lines.

Laser Cutting Production Line

 

We have 3 laser cutting machines with the total capacity from 1KW to 3KW. It can deal with the maximum thickness of up to 20mm for ordinary steel. These machines enable us to produce custom metal parts more easily and flexible without tooling cost investment and minimum order quantity request.

Robot Welders

 

We have 3 robot welders for welding the custom parts automatically. Using the robot welders in our manufacturing processes has significantly improved the welding quality and also reduced labor work.

Fully Automatic Powder Coating Line

 

For improving the production efficiency and also the painting quality, we have introduced the modern fully automatic painting line for our air distribution products such as metal air valve, swirl diffuser, iris damper and also some custom stamping parts. Any color upon request is available, with our current standard painting colors being RAL9010, RAL9016, RAL9003, RAL9006, etc.

In-house Tooling Workshop

 

We have our own in-house tooling workshop, which enables us to design, engineer and produce different types of tooling (transferred and progressive) for our customers’ needs. This capacity is one of our greatest strengths comparing to the other manufacturers who need to outsource the tools to sub-suppliers. With our in-house tooling workshop in place, we are managing to decrease the development costs, which consequently makes our products much more competitive in contract to other manufacturers in the industry.

Assembling Lines

 

At our factory, we have also introduced assemble lines for our HVAC accessories (10 assembling lines at the moment). Using the assemble lines enables us to improve our packing efficiency by at least 20%.
