Aluminum extrusion is one of our techniques
used to manufacture prototypes and volume aluminium profiles with machining or
EDM features. NextProto works with some of the best and reliable aluminium
extruding suppliers in China. Secondary operations such as CNC machining and
EDM process to the extruded aluminum profiles are processed at Nextproto or
outsourced.
People use this manufacturing process to make metal bar and tube, heat sinks or
profiles for CNC machining in high volume production parts. The main advantage
of extruded aluminum prototypes is its ability to create very complex
cross-sections. All parts done by us will have an excellent surface finish.
Tips: Hollow cavities within extruded
material cannot be produced using a simple flat extrusion die, because there
would be no way to support the center barrier of the die. Instead, the die
assumes the shape of a block with depth, beginning first with a shape profile
that supports the center section. The die shape then internally changes along
its length into the final shape, with the suspended center pieces supported
from the back of the die. The material flows around the supports and fuses
together to create the desired closed shape.
Our strict quality system can help to avoid surface cracking, internal cracking
and surface lines. We can take very good control on the extrusion temperature,
speed and friction so that we can make sure the good quality of the extruded
aluminum prototypes. Contact Next Proto customer service team today and we will
be more than happy to give you the advice on manufacturing your extruded parts.
