feature prevents con-

tamination of high-

quality materials and

provides optimum dry-

ing conditions. The

complete drying bin

body is made from a

single piece of special

glass – ideal for con-

tamination critical

process applications.

An additional benefit of the all glass con-

struction is its transparency. The operator can

always see the actual status of material in the

bin. Constant and stable conditions in the en-

tire drying hopper are an essential prerequi-

site. Therefore, the complete drying hopper

right down to the material discharge is heat

insulated because of a double glass wall con-

struction. This design is an important energy

saving advantage. The expertly designed air

diffuser provides uniform distribution of the

dry air ensuring that the material – even at

the material bin outlet – is kept at a constant

temperature and in the required dry condi-

tion.

METRO G

motan-colortronic's spotlight this year will be

focused on its innovative METRO G range of material loaders.

This development by motan engineers combines the latest tech-

nologies from colortronic and motan and also enhances those

systems with a number of new features. METRO G's modular

building block system allows users to configure and create the

optimal material loader for any application. For example, a stan-

dard material loader unit can be expanded into a clean room

version just by adding special vacuum diaphragm valve. A dust

removal module provides for fine dust removal at the material

loader, essential for some critical engineering plastics where ab-

solutely no dust is allowed to enter the process. The system can

also be fitted with modules with a tangential material inlet to

provide a cyclone effect for processing those materials where a

more coarse dust separation is required. METRO G allows users

to configure the right material loader for their specific applica-

tion.

ULTRABLEND

ULTRABLEND offers clear advantages to manufacturers of ther-

moplastic medical devices. The processing of raw material com-

pounds that are sometimes extremely expensive in hygienically

clean operations into medical primary packaging, components,

implants, instruments and equipment requires the highest levels

of cleanliness, precision and cost discipline.

The gravimetric ULTRABLEND blender has been developed for

consistently precise dosing and mixing of free-flowing raw ma-

terials – plastic granulates and additives. It improves process

quality and stability and makes its own contribution towards

minimising production costs. With the design in electro-polished

stainless steel, motan has placed great emphasis on clear func-

tions, minimum maintenance and easy operation in a hygieni-

cally clean production environment. All material hoppers and

mixing chambers have been designed without any “dead

zones”. All seams are fully welded. As a

result, no residual amounts of material can

build up and contamination of subsequent

batches is therefore eliminated.

The ULTRABLEND is especially suitable for

precise dosing of extremely small amounts

of material directly into the injection

moulding, extrusion or blow moulding

machine. A maximum of four raw mate-

rial

components can be

dosed by weight, one

after the other, precisely

as required by the recipe.

They are then mixed to-

gether homogeneously

in the downstream mix-

ing chamber (4.5 litres

volume) and fed into the

feed throat of the pro-

cessing machine. The

minimum dosing amount

is 3 g per component

(900 g lot size).

When two components

are used a maximum

throughput of 260 kg/h can be achieved.
