It absorbs moisture, changes size with it, and softens at 70 degrees. Thirty percent short glass fibre changes all four: tensile strength doubles, the heat deflection temperature goes past 250 degrees, the expansion coefficient in the flow direction falls by two thirds, and notched impact halves.<\/p>\n<p>The mechanism is load transfer. A fibre carries load only if it is longer than the critical length for the fibre and matrix combination, and only if it is aligned with the load. Both conditions are set by the moulding process, not by the compound datasheet. That is why two moulders using the same pellet can deliver parts that behave like different materials.<\/p>\n<table>\n<thead>\n<tr>\n<th>Glass, %<\/th>\n<th>Tensile, MPa<\/th>\n<th>Notched Charpy, kJ\/m2<\/th>\n<th>HDT at 1.8 MPa, C<\/th>\n<th>Density, g\/cm3<\/th>\n<th>CLTE flow, 1e-6\/K<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>0<\/td>\n<td>80<\/td>\n<td>14<\/td>\n<td>70<\/td>\n<td>1.14<\/td>\n<td>90<\/td>\n<\/tr>\n<tr>\n<td>15<\/td>\n<td>120<\/td>\n<td>10<\/td>\n<td>215<\/td>\n<td>1.25<\/td>\n<td>40<\/td>\n<\/tr>\n<tr>\n<td>30<\/td>\n<td>165<\/td>\n<td>7<\/td>\n<td>250<\/td>\n<td>1.36<\/td>\n<td>25<\/td>\n<\/tr>\n<tr>\n<td>45<\/td>\n<td>200<\/td>\n<td>5<\/td>\n<td>252<\/td>\n<td>1.52<\/td>\n<td>18<\/td>\n<\/tr>\n<tr>\n<td>50<\/td>\n<td>210<\/td>\n<td>4.3<\/td>\n<td>255<\/td>\n<td>1.58<\/td>\n<td>15<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p class=\"tablecap\">Table 1 - Typical dry-as-moulded values for PA66 with short glass fibre. The impact column is plotted at four times scale on the first figure so that it shares an axis with strength.<\/p>\n<p>Those are dry values, and dry is a laboratory condition. Nylon at 50 percent relative humidity holds about 2 percent water, which plasticises it: a 30 percent glass grade drops from 165 to roughly 110 MPa and its impact roughly doubles. Both numbers are correct, and a drawing that does not say which one it means is not a specification.<\/p>\n<div class=\"callout\">State dry-as-moulded or conditioned on the drawing, and state the conditioning.

By the time the melt reaches the gate the mean length is a few hundred microns, and by the end of the flow it is less.

The loss is front-loaded: two thirds of the length is gone before the melt leaves the barrel.<\/p>\n<p>The screw and check valve do the most damage, and they do it through back pressure and screw speed rather than through injection. A back pressure of 100 bar instead of 20, or a screw speed of 200 rpm instead of 80, will cut the mean length by a third without changing any other setting on the machine.<\/p>\n<p>The second largest loss is the gate. A gate smaller than 60 percent of the wall thickness, a tunnel gate, or a hot-drop with a 1.5 mm tip will all shear the fibre hard. Full-round runners with a diameter at least 1.5 times the part thickness, and a gate that is generous rather than neat, are worth more than any additive.<\/p>\n<div class=\"myth\"><b>\"Faster injection fills the part before it freezes, so it must be better.\"<\/b> Up to a point. Past the shear threshold the extra speed breaks more fibre than the shorter fill time saves, and the part that fills easily is the one that fails in fatigue.<\/div>\n<h2 id=\"warp\">Warp: the anisotropy you cannot anneal out<\/h2>\n<p>A 30 percent glass grade shrinks about 0.3 percent in the flow direction and about 1.0 percent across it. A flat 200 mm plate therefore wants to be 1.4 mm shorter in one direction than in the other, and unless the flow pattern is symmetric the plate relieves that difference by bowing.<\/p>\n<p>This is a design and gate-position problem more than a machine-setting problem. Settings can reduce the gradient; they cannot remove the orientation that creates it. Annealing relieves moulded-in stress, which is a different thing, and a warp that comes from differential shrinkage comes back after annealing.<\/p>\n<table>\n<thead>\n<tr>\n<th>\u041f\u0440\u0438\u0447\u0438\u043d\u0430<\/th>\n<th>What it looks like<\/th>\n<th>What fixes it<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Differential shrinkage, flow against cross-flow<\/td>\n<td>Saddle or dome on a flat face<\/td>\n<td>Symmetric gate position, flow simulation, re-orient the gate<\/td>\n<\/tr>\n<tr>\n<td>Wall thickness variation<\/td>\n<td>Local sink with an overall bow<\/td>\n<td>Uniform wall, rib instead of thick section<\/td>\n<\/tr>\n<tr>\n<td>Uneven cooling between the two halves<\/td>\n<td>Bow toward the hot side<\/td>\n<td>Balance the circuits, 80 to 100 C on both halves<\/td>\n<\/tr>\n<tr>\n<td>Packing gradient along the flow<\/td>\n<td>One end over-packed<\/td>\n<td>Packing profile, larger gate, longer hold<\/td>\n<\/tr>\n<tr>\n<td>Ejection force<\/td>\n<td>Twist or a bent edge<\/td>\n<td>More ejector area, correct draft, slower ejection<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p class=\"tablecap\">Table 3 - The five practical causes of warp in glass-filled nylon, in order of how often they are the real one.<\/p>\n<p>The design answer is to stop asking for flat and start asking for functional. A glass-filled nylon bracket that must be flat within 0.1 mm over 200 mm will be machined flat after moulding or will be moulded in a fixture. A bracket that must sit on three pads within 0.3 mm is a moulding problem that can be solved.<\/p>\n<h2 id=\"tool-wear\">Tool wear: glass is abrasive, and it is worst at the gate<\/h2>\n<p>Glass fibre is harder than the steel it flows past. The wear points, in order, are the gate, the sprue bush, the check valve and the screw tip. A worn gate shows up first as a stringy part or a flash line, then as a dimension that drifts slowly enough that nobody notices until the parts stop fitting.<\/p>\n<table>\n<thead>\n<tr>\n<th>Glass loading<\/th>\n<th>Gate steel<\/th>\n<th>Hardness<\/th>\n<th>Expected gate life<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Unfilled<\/td>\n<td>P20 (1.2311)<\/td>\n<td>30 HRC<\/td>\n<td>Over 1 million shots<\/td>\n<\/tr>\n<tr>\n<td>15 percent<\/td>\n<td>P20 nitrided or 1.2343<\/td>\n<td>48 HRC<\/td>\n<td>Around 500,000<\/td>\n<\/tr>\n<tr>\n<td>30 to 35 percent<\/td>\n<td>1.2343 ESR, PVD coated<\/td>\n<td>50 to 52 HRC<\/td>\n<td>Around 300,000<\/td>\n<\/tr>\n<tr>\n<td>45 to 50 percent<\/td>\n<td>Powder metallurgy steel, PVD<\/td>\n<td>60 HRC<\/td>\n<td>Around 250,000, insert replaced<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p class=\"tablecap\">Table 4 - Gate steel selection by glass loading. The life figures assume a 2 mm wall, a full-round runner and a gate of at least 1 mm; a small gate multiplies the wear rate.<\/p>\n<p>Design the gate as a replaceable insert even on a low-volume tool. It is a 40 euro part that turns a worn tool into a tool change rather than a new tool, and it lets you change the gate size after the first trial without touching the cavity.<\/p>\n<p>The screw and barrel wear too, but slowly and invisibly. A bimetallic barrel with a tungsten carbide liner is the standard answer for glass loadings above 30 percent, and it is cheaper than the downtime from a barrel that has lost 0.3 mm of clearance and can no longer hold a cushion.<\/p>\n<h2 id=\"drying\">Drying is not optional, and it is measured<\/h2>\n<p>PA66 absorbs 1.5 to 2.5 percent water at saturation. Above about 0.15 percent in the melt, the water hydrolyses the amide bonds: molecular weight falls, strength falls, and the part shows silver streaks and a brittle break. The damage is done in the barrel in a few seconds and it is not recoverable.<\/p>\n<p>Dry at 80 to 90 degrees for four hours in a desiccant dryer holding minus 20 degrees dew point. PA66 tolerates 100 to 120 degrees and dries faster, but the pellets soften and cake above about 100, so most shops stay at 90 and accept the longer time.<\/p>\n<p>Verify with a moisture analyser, not with a timer. Loss-on-drying at 200 degrees for 20 minutes is adequate for a shop floor check; Karl Fischer is the reference method for a dispute.<\/p>\n<div class=\"callout\">A dryer set to 90 degrees with saturated desiccant delivers hot humid air. Measure the dew point of the air going in, not the temperature of the hopper.<\/div>\n<h2 id=\"process\">Settings that keep the fibre long and the part flat<\/h2>\n<p>The window for glass-filled nylon is wide, which is why so many parts are moulded outside it. These are the settings that matter, in the order they matter.<\/p>\n<ul>\n<li>Melt temperature 285 to 300 C for PA66 with glass, 270 to 285 C for PA6. Below 280 the melt is too stiff to fill without shear; above 310 the nylon degrades.<\/li>\n<li>Mould temperature 80 to 100 C. A cold mould gives a glossy part with high moulded-in stress and worse warp; a hot mould gives a matte part that is flatter and stronger.<\/li>\n<li>Back pressure 10 to 30 bar. This is the single largest lever on fibre length and the one most often set at 80 bar out of habit.<\/li>\n<li>Screw speed 60 to 100 rpm, and a decompression of 2 to 3 mm before plasticising to release pressure on the melt.<\/li>\n<li>Fill in 0.3 to 0.8 s for a 2 mm wall, with a profile that keeps the gate velocity steady rather than spiking at the start.<\/li>\n<li>Cushion 5 to 10 mm, and hold until the gate freezes, which is 2 to 4 s for a 2 mm wall.<\/li>\n<\/ul>\n<p>On a hot runner, use a full-flow nozzle of at least 3 mm and avoid restrictive thermal tips. A valve gate with a 4 mm orifice costs more and breaks less fibre, and on a 30 percent glass part it pays for itself in scrap.<\/p>\n<h2 id=\"quality\">What to inspect, and how<\/h2>\n<p>The usual incoming inspection is a tensile test on a specimen, which tells you almost nothing about the part. These are the checks that correlate with how a glass-filled part behaves.<\/p>\n<ul>\n<li>Glass content by thermogravimetric burn-off, within 2 percentage points of nominal. It catches a compound that was mixed wrong, which is more common than it should be.<\/li>\n<li>Fibre length by pyrolysis, dispersion of the ash in a liquid, and microscope measurement. Report the mean and the 10th percentile, not just the mean.<\/li>\n<li>Dispersion by burn-off and optical examination, looking for unfused bundles that appear as light patches on a fractured surface.<\/li>\n<li>Warp on a CMM against a fixture, at 23 C and 50 percent relative humidity, after 24 hours of conditioning. Measure it dry and measure it conditioned; the difference is the moisture-driven part of the warp.<\/li>\n<li>Dimensions by SPC on the critical features only. Glass-filled nylon moves 0.02 to 0.05 percent per percent of moisture, which is more than the moulding tolerance on a long dimension.<\/li>\n<\/ul>\n<p>The most useful single number is the spread of the fibre length distribution. A batch with a mean of 300 microns and a 10th percentile of 80 microns will fail in fatigue while every coupon test passes, because the short fibres are doing nothing and the load is carried by a shrinking fraction of the section.<\/p>\n<div class=\"faq\">\n<h3>Can I mould a thin wall in 50 percent glass nylon?<\/h3>\n<p>You can, but the impact falls to about 4 kJ\/m2 and the fill pressure rises sharply. Below 1.2 mm, 30 percent glass is usually the practical limit, and a 15 percent grade with a ribbed design often outperforms a 50 percent grade in the same envelope.<\/p>\n<h3>Why does my glass-filled part have silver streaks?<\/h3>\n<p>Almost always moisture. Nylon at 0.3 percent moisture produces visible streaks and a measurable loss of molecular weight. Check the dew point of the dryer before changing any process setting.<\/p>\n<h3>Does glass-filled nylon need a hot mould?<\/h3>\n<p>Yes, 80 to 100 C. A cold mould produces a part with high residual stress, poor surface and worse warp, and the cycle time saved is usually given back in scrap.<\/p>\n<h3>Why does the part warp again after annealing?<\/h3>\n<p>Because the warp came from fibre orientation, not from moulded-in stress. Annealing relieves stress; it does not re-orient fibre. Only a gate or flow change fixes orientation-driven warp.<\/p>\n<h3>Can I use regrind?<\/h3>\n<p>Up to 20 to 25 percent, if it is dried and if fibre length is not critical. Regrind has already been through one thermal cycle and its fibre is shorter, so a 30 percent glass part made with 25 percent regrind behaves like a 24 percent glass part.<\/p>\n<h3>What tolerance can I hold on a glass-filled nylon part?<\/h3>\n<p>Plus or minus 0.05 mm on a small feature, and 0.1 to 0.2 mm across a long flow direction once moisture and anisotropy are included. Tighter than that needs a machining operation or a different material.<\/p>\n<\/div>\n<div class=\"cta\">\n<p class=\"cta-h\">Moulding a glass-filled nylon part?<\/p>\n<p>Send the drawing and the load case. We will tell you the glass loading, the gate position and the gate steel before the tool is cut, because all three are decided once and paid for forever.<\/p>\n<p><a class=\"btn\" href=\"https:\/\/uplastech.com\/ru\/custom-injection-molding\/\">Talk to an injection engineer<\/a>\n<\/div>\n<div class=\"rel\">\n<h4>Continue reading<\/h4>\n<ul>\n<li><a href=\"https:\/\/uplastech.com\/ru\/nylon-pa-injection-molding-guide\/\">Nylon PA Injection Molding: A Practical Guide<\/a><\/li>\n<li><a href=\"https:\/\/uplastech.com\/ru\/injection-mold-steel-selection\/\">Injection Mold Steel Selection<\/a><\/li>\n<li><a href=\"https:\/\/uplastech.com\/ru\/injection-molding-tolerances\/\">Injection Molding Tolerances<\/a><\/li>\n<li><a href=\"https:\/\/uplastech.com\/ru\/injection-molding-design-guidelines\/\">Injection Molding Design Guidelines<\/a><\/li>\n<li><a href=\"https:\/\/uplastech.com\/ru\/pps-peek-injection-molding-guide\/\">PPS and PEEK Injection Molding<\/a><\/li>\n<\/ul>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Thirty percent glass takes nylon from 80 to 165 MPa and from 14 to 4.3 kJ\/m2 of notched impact.
