Versatile specialistsApart from bimetallic cylinders,

Kluin Wijhe offers other services, such as

deephole drilling and the manufacturing

of precision products. If, after deephole

drilling, certain parts need further

machining or treatment, we shall be glad

to assist you. In this way, you save time as

well as money. If you involve us in your

production process at an early stage, you

can make optimum use of our services.

Besides, our advice often results in

substantial savings.

Cylinders made to measureIf you need single or twin-screw cylinders

for new or broken down injection

moulding and extrusion machines, then

you want them made to measure.

Literally and figuratively! Literally: the

dimensions ordered are the dimensions

supplied - accurately to the 0.01 mm.

Figuratively: delivery times and other

agreements are handled just as carefully.

Indeed, as long as your machines are

stopped you incur production losses.

Only established specialists who know

your problems and are ready to advise

and assist you, can offer you this service.

Kluin Wijhe, the bimetallic specialistsAt Kluin Wijhe, metal runs "in their

blood". Our know-how of materials and

processing techniques is exceptional. For

example, we can extend the life of injection

and extrusion cylinders by five to ten

times by using bimetallic. A specialist

technique, which is in safe hands with us.

We can apply internal metal alloys up to

12 mm thick, whilst guaranteeing

minimal tolerances.

Obviously, you can rely on us, because

we have been ISO 9002 quality certified

ever since 1982 and, besides, we are a

member of the Aalberts Industries N.V.

The hard factsKluin Wijhe uses a centrifugal techniquefor its manufacture of bimetallic cylinders.In this process, cylinders are casted witha hard metal alloy in an extremely sophisticated furnace at a temperature of approx. 1200°C.

The great advantage of bimetallic liningsis that their hardness is even throughoutthe layer thickness. Contrary to nitridedcylinders. Thanks to the bimetallictechnology, cylinders offer even betterabrasion and corrosion resistance underhigh temperatures and pressure.

It goes without saying that dimensionalvariations and inaccuracies are reducedto the absolute minimum. This meansthat the life of your cylinder can be improved by a factor of five to ten. Kluin Wijhe is one of few companiesspecialized in bimetallic linings.

How many KB do you need?The abrasion resistance of the lining depends on the lining chosen. There arefour levels of quality, of which KB 350guarantees the best abrasion resistance.

CYLINDERS

SCREWS IN PRACTICE

In injection moulding and extrusion

machines, temperatures and pressure

may rise very high. Besides, the raw

materials to be processed are often

aggressive and abrasive and reduce the

economic life of the cylinder and screw.

Since economic life and effective produc-

tion time are of vital importance, high

demands are made on the various parts.

Kluin Wijhe manufactures and supplies

bimetallic cylinders and screws which

match with the highest demands.

Speciality of the houseApart from single-screw cylinders,

Kluin Wijhe also manufactures

bimetallic twin-screw cylinders.

The twin cylinder is manufactured by

joining two cylinders of exactly the same

size. This process is carried out with

extreme precision in order to guarantee

minimal tolerances.

Should you require further details after

reading the brief description of our services in

this brochure, please contact us. We can then

directly respond to your specific questions or

requirements. For more information or an

appointment, please call ++31-(0)570-52 87 77.

Pressure sleevesThe pulsating injection of injection

moulding machines produces extremely

high pressures on the discharge side

of the cylinder. Usually, the newly

developed backing materials provide

sufficient protection. If construction or

extremely high pressures require addi-

tional strength, a pressure sleeve is

shrunk on to the discharge side of the

cylinder to ensure that the materials can

withstand high levels of pressure.

Pressure sleeve

We do more than just cylinders.For an efficient production process, the cylinder and screw must be gearedto one another to the optimum. That iswhy Kluin Wijhe as a manufacturer ofbimetallic cylinders is also able to sup-ply the right screw. As a complete unit,which does what it must do.

ScrewsOur service has come to perfection

through the additional supply of the

pumping heart of the machine, "the

screw". This is how we guarantee

optimum adjustment between cylinder

and screw. The screws and tips are

manufactured entirely according to your

requirements or applications, whether

gas-nitrided, armoured, coated or

hardened. And in the case of screws,

repair is often more economical than

replacement.
