Processing information for the injection moulding of GrilamidLV-3H

This technical data sheet for Grilamid LV-3H pro-

vides you with useful information on material prepa-

ration, machine re, tooling and process-

ing.

MATERIAL PREPARATION

Grilamid LV-3H is delivered dry and ready for proc-

essing in sealed, air tight packaging. Predrying is

not necessary.

Storage

Sealed, undamaged bags can be kept over a long

period of time in storage facilities which are dry,

protected from the influence of weather and where

the bags can be protected from damage.

Handling and safety

Detailed information can be obtained from the

“Material Safety Data Sheet” (MSDS) which can be

re with every material order.

Drying

Grilamid LV-3H is dried and packed with a moisture

content of less than 0.10 %. Should the packaging

become damaged or the material is left open too

long, then the material must be dried. A too high

moisture content can be shown by a foaming melt

and silver streaks on the moulded part when in-

jected freely into the atmosphere (free shot).

Drying can be done as follows:

Temperature: max. 80°C

Time: 4 - 12 hours

Dew point of the dryer: -25°C

Temperature: max. 100°C

Drying time

If there is only little evidence of foaming of the melt

or just slight silver streaks on the part, then the

above mentioned minimal drying time will be suffi-

cient. Material, which is stored open over days,

which shows strong foaming, unusually easy flow-

ing, streaks and rough surface on the moulding

part, then the maximal drying time is required.

Silver streaks can also be caused by

overheating of the material or by too long

melt residence time in the barrel.

Drying temperature

Polyamides are subjected to the affects of oxidation

at temperatures above 80°C in the presence of

oxygen. Visible yellowing of the material is an indi-

cation of oxidation. Hence temperatures above

80°C for desiccant dryers and temperatures above

100°C for vacuum ovens should be avoided. In

order to detect oxidation it is advised to keep a

small amount of granulate (light colour only !) as a

comparison sample.

At longer residence times (over 1 hour) hopper

heating or a hopper dryer (80°C) is useful.

Use of regrind

Grilamid LV-3H is a thermoplastic material. Hence,

incomplete mouldings as well as sprues and run-

ners can be reprocessed. The following points

should be observed:

•  Moisture absorption

•  Grinding: Dust particles and particle size distri-

bution

•  Contamination through foreign material, dust,

oil, etc.

•  addition to original material

•  Colour variation

•  Reduction of mechanical properties

When adding regrind, special care has to be taken

by the moulder.

MACHINE REQUIREMENTS

Grilamid LV-3H can be processed economically and

problem-free on all machines suitable for poly- am-

ides.

Screw

Wear protected, universal screws with shut-off

nozzles are recommended (3 zones).

Length: 18 D - 22 D

Compression ratio: 2 - 2.5

Shot volume

The metering stroke must be longer than the length

of the back flow valve (without decompression

distance).

Shot volume = 0.5 - 0.8 x

(max. shot volume)
