Maximum rigidity + long-term dimensional hold—engineered for structural brackets and reinforcement parts.
When GF30 still feels “a bit soft,” the problem is usually not ultimate strength—it’s deflection and creep in real geometry: long spans, rib-heavy carriers, fastened brackets that slowly relax, or assemblies where micro-movement turns into noise and fit drift.
ABS GF35 is built for these hard-mode parts—where your business KPI is minimum flex, stable fit, stable output.
Yongjinhong ABS GF35
ABS GF35 is an ABS matrix reinforced with ~35% glass fiber, compounded for injection molding with controlled dispersion and stabilizer systems aimed at:
-
Very high stiffness / modulus (reduce deflection)
-
Better creep resistance (hold geometry and fastener load over time)
-
Improved heat deformation resistance (hot-soak shape retention)
-
Dimensional stability (repeatable fit—when gate/cooling are disciplined)
Important reality check:
At 35% GF, the part behavior becomes more direction-dependent. Anisotropic shrink and fiber orientation effects increase, so warpage control becomes a mold + process + material system.
Yongjinhong ABS GF35 Raw Material
1) Structural stiffness that stops flex-driven issues
Engineering: GF35 significantly increases modulus vs GF30, reducing deflection under load.
Buyer value: tighter assembly feel, less micro-movement, lower NVH risk, less gap drift over time.
2) Stronger creep control (long-term dimensional hold)
Engineering: higher fiber fraction improves resistance to long-term relaxation under load.
Buyer value: better torque retention, fewer “slow changes” that appear after weeks/months.
3) Heat-cycle stability for demanding environments
Engineering: reinforcement supports shape retention under hot-soak and thermal cycling (design/test dependent).
Buyer value: fewer seasonal fit surprises, fewer rework loops after validation cycles.
Best-Fit Applications
ABS GF35 is most valuable where the part is functionally structural:
|
|
|
|
Structural Brackets & Carriers
-
mounting brackets that must not flex
-
module carriers and reinforcement frames
-
fastened components where torque retention matters
Reinforcement Backbones / Support Frames
-
long structural backbones under vibration
-
rib-heavy carriers that need stable geometry
Precision Structural Frames (function-first)
-
mechanical frames where geometry drives feel and function (less emphasis on Class-A cosmetics)
If your part is Class-A appearance or high-gloss cosmetic, GF35 is usually not the first choice unless you plan texture/paint strategy or a surface-optimized variant.
Performance Target Map
Values vary by formulation, color, fiber type, and test standard. Use this as a decision compass.
| Attribute | ABS GF30 | ABS GF35 | What to expect |
|---|---|---|---|
| Stiffness / Modulus | Very High | Ultra High | Less deflection |
| Creep resistance | Best | Best+ | Better long-term hold |
| Heat deformation resistance | Highest (ABS GF family) | Highest+ | Better hot-soak retention |
| Warpage sensitivity | Higher | Higher++ | Needs gate/cooling discipline |
| Surface fiber signature | Higher | Higher++ | Texture/paint helps |
| Process window tolerance | More sensitive | Most sensitive | Repeatability is key |
Positioning in Your ABS GF Series (GF15 / 20 / 25 / 30 / 35)
A clear product-family story helps buyers self-select:
-
GF15: balanced stiffness + easier molding/surface
-
GF20: stiffness upgrade with controlled risk
-
GF25: bridge grade (GF20 not enough, GF30 too sensitive)
-
GF30: structural grade (minimum flex for most projects)
-
GF35: maximum structural stiffness for the toughest deflection/creep cases
Injection Molding Guidance
GF35 can mold well, but it demands a stable process and a warpage plan.
Practical trial setup (starting points):
-
Drying: recommended for surface consistency and stable flow
-
Melt temperature: ~235–275°C (optimize flow while protecting stability)
-
Mold temperature: ~80–110°C (helps shrink stability and weld-line quality)
-
Injection speed: medium-to-high (avoid hesitation; strengthen knit lines)
-
Packing/holding: consistent and repeatable (avoid over-packing that amplifies stress)
Warpage control checklist (non-negotiables):
-
gate location controls fiber orientation → warpage direction often follows flow
-
uniform cooling is critical (avoid hot spots and uneven shrink)
-
rib and thickness transitions must be disciplined
-
venting prevents burn and uneven shrink from trapped gas
-
for long parts, consider flow balance and cooling circuit review early
OEM Customization (what usually matters at GF35)
At GF35, most projects ask for:
-
Low warpage route (shrink-balance + orientation control focus)
-
Heat-aging stability (hot-soak + thermal cycling)
-
Impact tuning (for bosses/snaps if fracture risk shows up)
-
Color & surface strategy (often black; texture/paint-friendly package)
What you should provide
No sensitive details needed—just engineering facts:
-
part type + function (bracket/carrier/backbone/frame)
-
wall thickness range + flow length direction
-
biggest pain: deflection, creep, hot-soak drift, warpage direction, weld-line cracks
-
surface requirement (paint/texture vs exposed cosmetic)
-
gate constraint (fixed/adjustable) and runner type (hot/cold)
Even wall thickness + failure mode + part photo is enough to start.
