Materials Choosing For CNC Machining
Many products need to be made prototype by manufacturers to
test the feasibility and appearance
of products. Manufacturing prototype is the
most direct way to find defect, shortage, disadvantage
of the real prototype
compared with product design. After improve the defect, it can put into
batch
manufacturing. So the significance and precision of prototype manufacturing
directly decide
the batch manufacturing conforming to design requirements or
not. So what kind of Matters needing
attention when manufacturing CNC
prototype?
1. General prototype . The material of general prototype
always is ABS. ABS is easy to process
and the post- processing also pretty.
2.The prototype with high temperature resistance. The
material can be epoxy resin,bakelite,
black PC, PA. Except the PC, other three
materials can not be glued and need to be entirely machined.
3.
Prototype with abrasive resistance. The material can be POM or PA. These two
materials need
to be entirely manchined.
4. Prototype with high toughness. The material can be PA and
pp. These two materials need
to be entirely manchined.
5.
Transparent prototype. The material can be PMMA, transparent ABS, transparent
PC. After polishing,
the prototypes in these materials reach the effect of real
prototype with high transparency.
6. The surface finished of prototyppe can be divided into oil
spraying, plating, polishing,
silk-screen and pad printing. The oil spraying
can be divided into glossy surface, matte surface,
sandy surface, transparency,
translucency, fluorescence colour and robber process oil.
Such matters need to
be noticed.
