Advantages of the extrusion process :
The extrusion process provides virtually unlimited opportunities
for aluminium product shapes. Costs are cut by designing fewer
components, which reduce fabrication and simplify assembly.
These features and benefits are unmatched by other materials and
processes
(1) High Quality
(2) Cost effective
(3) Low tooling costs
(4) Design flexibility
(5) Versatility in joining
(6) Machinable
(7) Rapid prototyping
(8) Short lead times
(9) Wide range of finishes
Questions & Answer
Q1: What is aluminum extrusion, fabrication, and anodization?
A: Aluminum Extrusion refers to a process of creating shapes with
an aluminum billet or log by forcing it to flow through a shaped
opening in a die. Aluminum can be extruded into standard shapes or
specific designs depending on a customer’s preference.
Aluminum Fabrication refers to building aluminum components by
cutting, drilling, slotting, tapping,bending, CNC machining,
mechanical assembly and welding.
Aluminum Anodization is an electro-chemical process of coating
aluminum with a thin layer of oxide to increase corrosion
resistance and harden the surface.
Aluminum also can be dyed with various anodizing colours,which in
most widely used is Brone shades.
Q2: What’s the thickness for anodizing? Can you do 15um?
A: Our normal thickness is about 10 um. Yes, we can do 15um and
above.
Q3: What color you can do for powder coating? The thickness for
powder coat?
A: We can do any color for powder coat as long as you can provide
the color sample. Our normally powder coating thickness is 60-80um.
Q4: What color you can do for wood grain?
A: Our most popular colors are Western Red Cedar, Australia Cedar,
Jarrah I, Jarrah II, Chestnut, Bush Cherry, Bush Wood, Western
Wood, Snow Gum, etc. If you need any other colors, we can do
according to the color samples you provide.
Q5: What’s the delivery time for samples and mass production?
A: (1). 2 weeks to open the new moulds and make samples.
(2). 3-4 weeks after receipt of deposit and confirmation of the
order.
