THREE MAIN METHODS WHICH ARE USED FOR PRODUCING THE KORMAX RANGE OF PLASTICS MATERIALS:
Plastic Extrusion
Plastic Extrusion is a manufacturing process in which
small beads [up to 2mm in diameter] are melted and
formed into a continuous profile. Extrusion process is
commonly used for producing rod, sheet, tube, profiles
and sheeting. Not all plastic materials can be extruded
as some plastic materials are produced by casting
[chemical reaction] or compression moulding.
Plastic Casting Process
Some plastics materials can be both extruded and cast,
nylon being an example. The casting process allows just
about any size and thickness to be produced without
degradation of the materials internal structure. Along
with a large range of sizes that are able to be produced
by casting, additives can be added to improve wear
resistance, heat stability and impact resistance.
The extrusion process starts by feeding the small plastic beads from a hopper into the barrel of the extruder. The
material is gradually melted by the mechanical energy generated by the extruder screw turning and heaters in the
barrel of the extruder. The molten plastic is then forced into a die which creates the shape of the plastic, the material
then cools and solidifies into the finished shape. Material is then cut to various lengths which can vary from less than
1m to up 100m [for small profiles that can be coiled]. Custom made shapes and sizes can be produced however new
dies maybe required which can cost anywhere from $1500 up to $10000’s depending on how complex the shape
of the profile. Special runs of different colours and sizes are also possible. They however, are subject to minimum
quantities [which could be something like 500metres or 1000kg or more] depending on material and shape. Common
materials that are extruded are PVC, polypropylene, acetal, PETP, nylon and polyethylene.
Most cast plastics are produced by mixing a number of chemicals together, then introducing an activator and
catalyst which causes a chemical reaction to happen. The liquid is then poured into a mould, (some times under
vacuum, under pressure or just at atmospheric pressure). The moulds maybe heated and the material solidifies
in the mould. The material may stay in the mould for mins, hours or days depending on material type, shape and
size. Moulds can be simple to very complex [range in price for $100 to $10000’s] depending on material, part and
quantities required. Similar to extruded materials, some materials require further treatment once cast to relieve stress
and improve dimensional stability. This is often achieved by heat treating in ovens over a long period of time.
Common plastic materials which are cast are nylon, polyurethane and acrylic.
The compression moulding process can start with either a powder or partly cured material. The material is compressed
in a mould, in some instances heat is applied, whilst under pressure the material takes the shape of the mould and
the shape is formed. Some materials [PTFE for example] after being compression moulded are then required to be
sintered. Sintering is a process where the part is placed in an oven to be heated and cooled in a very controlled
manner over a number of days or even longer depending on the part size.
Common materials to be compression moulded are UHMWPE, PTFE, and PEEK

Compression moulding
Third most common method for producing plastic
materials is compression moulding. Some of the plastic
raw materials are not in liquid form, not able to mixed
with chemicals or catalysts to react, or just not easily
able to be formed by heating alone. Hence a process
called compression moulding is used.
Overview
Kormax Acetal [technical name Polyoxymethylene] generally comes in either natural white or black colour. Material
has low moisture absorption [stable in humid environments], excellent machinability and its FDA compliance allows
for direct contact with food stuffs. The black has improved UV resistance and is the preferred choice for outdoor /
applications in direct sunlight. It has good dimensional stability but should not be used in temperatures operating
above 80ºC.
Technical Information
MSD sheets, machining guidelines, chemical resistance and technical data available on request.
Availability
Most sizes are stocked in natural white colour, some sizes in black. Other colours such as red, blue, green etc., other
grades such as PE filled, metal detectable, anti static grades etc, and tube are available on special order but may be
subject to minimum order quantities.

Overview
Kormax PTFE [technical name Poly Tetra Fluoro Ethylene] is a fluorocarbon based material which has excellent
temperature and chemical resistance. Kormax PTFE is often used for non stick coatings due to its extreme slipperiness.
There are few other plastic materials which have such a low coefficent of friction. Whilst Kormax PTFE is a very dense
material, compared to other plastic materials it is quite soft and has low abrasion resistance. It is also produced with
different additives such as glass, carbon, bronze and stainless steel which improves various physical properties of
Kormax PTFE.
Technical Information
MSD sheets, machining guidelines, chemical resistance and technical data available on request.

Panel Saws, Drop saws and Beam saws are a common and effective means of cutting
sheet, rod and tube to size. It is recommended to use carbide tip blades with polished
top surfaces and good chip clearance can do many operations between sharpening's.
When cutting glass filled, glass re enforced and ceramic filled materials, tool life will be
shortened considerably. Good dust extraction system is essential to remove swarf, fine
dust from the cutting area. It is strongly recommended that materials are clamped when
cutting and on thicker sheets it maybe necessary to do 1 cut of 1/2 cutting depth, clear
the cutting path and then a final cut. Ideally saw blade should have a cutting speeds of
2000m/min, a tooth pitch of 3 - 5mm, a rake angle of 5 -10 degrees and a tooth clearance
of around 10 degrees.Saw
Turning
Machining of plastics materials in lathes can be done with both high speed steel tool bits or
with carbine inserts. Tooling should have polished top surfaces to help reduce the build up of
material on the inserts. Air blasts, swarf extraction systems right at the cutting face and flooding
the cutting face with a suitable coolant can be effective and removing swarf from the cutting
path or becoming entangled with moving or stationery parts. Cutting speeds of 300m/min and
feed rates of 12m/ mins, rake angles of 5 -10 degrees work well for most materials.
Bandsaw
Bandsaws, jigsaws and cut off bandsaws can be a very effective way of cutting plastic materials
to size and shape. In most instances it is difficult to use a lot of coolant hence feeds and speeds
should be kept to around 500m / min to avoid heating up and melting of plastic. Biggest nuisance
is swarf which can get caught up around bandsaw wheels, blade, melt and cause blade to
wander off. If doing a lot of cutting recommend stopping and cleaning out swarf frequently.
Blade should have a pitch of around 3 to 6mm, rake angle of 0 - 4 degrees and tooth clearance
angle of 15 - 30 degrees
Drill
High speed twist drills work fine for drilling most plastics materials, if drilling holes with a
depth of more than 2 times the diameter, then drill part way through, raise the drill to break
and clear out the swarf, make sure material is well clamped to avoid drill from grabbing and
picking up material. A 118 deg point angle with 10 - 15 degree lip clearance is recommended.
On a 12mm dia drill, use a speed of 700 rpm and feed rate of around 3mm per second. For
larger diameter holes, use a smaller pilot hole and progressively open out similar to drilling
steel, resist the temptation to use large drills and feeds as this can cause major stress in
the material, resulting micro cracks forming or in worst case material will break into pieces
cutting speed of 100m / min and feed rate of 15m/m work on most materials, but best to trial
and find optimum for each particular application.
Plastics Machining Tips
The following is a general guidelines for machining plastics for people that have not machined plastics before and the guide gives a starting point. Some things to be aware of before getting started
Plastic materials can expand up to 10 times more than metals. When measuring material, be aware of the ambient
temperature as sizes will change when material cools.
Plastic materials soften as they heat up. Materials also warp if large amounts of material are machined from 1 side
of a piece of sheet, try and machine plastics evenly.
For precision parts it is recommended to rough out parts close to size, rest the material, then finishing machining
with small final cuts.
Coolant can be used to remove heat and swarf, some plastics can be adversely affected when in contact with some
coolants, please check with Kormax that your coolant is not going to affect the material.
Plastic materials are generally softer than metals, thus can be marked a lot easier when held in vices or chuck jaws.
Soft jaws or holding on surfaces not seen can help the appearance of the finished product.
Vacuum beds, double sided sticky tape can be useful way on holding materials whilst being machined on routers
and milling machines.
Swarf can be a major nuisance when machining plastics. It heats up, melts around the cutters, can get caught up
in chucks, drills and around the machined parts. Use air blasts, coolant flooding and extraction systems to clear
the tool path. Also chip breakers, woodpecker cycles. interrupting the machining cycle and even stopping and
removing strands of material from the cutting area can prevent material getting caught up and prevent damage to
tooling and parts while machining.
In most instances, plastics will have different machining allowances, i.e. heavier interference fits, larger running
clearances and extra allowances for thermal changes than metals.
Whilst using plastic materials can give amazing results in some areas, they do have limitations and may not always
be the "best choice" as a direct replacement for metal parts without some changes to design.
Not all plastic materials machine the same, some can be very difficult for the novice. For example, Kormax Acetal
is very easy to machine, however, Kormax Polyurethane is very difficult due to its softness, but with freezing can be
a lot easier.
Most plastics materials can be machined on wood working or metal working equipment as long as correct speed,
feed and tool geometry are used.
For best accurate sizes and good surface finish, always use cutting tools that have not been used to machine
metals first.
